Options for aging metal by decorative painting. Painting of forged products

Iron is susceptible to corrosion, so regular painting of garage doors is essential. How to properly prepare the surface of the gate, and what resistant paint to choose? There are folk tricks that will help reduce costs and labor costs, as well as speed up the process of bringing the garage door in order.

If the gate is new, then special preparation is not necessary, it is enough to clean the surface of dust and coat it with a primer that protects the metal from corrosion and provides better adhesion of the paint to the metal.

How to paint garage doors if they are old and rusty?

Surface cleaning

There are several options for cleaning metal, the choice of method depends on the condition of the metal. If the metal is rusted to holes, then only replacing the gate will help, not painting. We offer a choice of methods for preparing old metal for applying a primer and paint.

Inexpensive and efficient

Budget, but tedious method. You will need the following tools:

spray bottle for water
metal and regular hard brushes;
skin (number 60 or 80, depending on the layer of rust);
"Kalosha" gasoline - should be used as a solvent for residues old paint, it is better than white spirit;
rag.

The cleaning process can take a whole day, but the costs are minimal. The sequence of actions is as follows:

thoroughly wash the gate and clean the dust and dirt with a stiff brush;
after washing, the metal must dry completely;
old paint that peels off, we clean it with a metal brush;
all the irregularities of the layers of the old coating that remain should be cleaned with sandpaper;
after stripping, it is necessary to degrease the metal with gasoline.

Do not forget that it is necessary to clean from rust not only the gate, but also the fasteners, and the welded frame, which is built into the walls. Often, rust from cold bridges quickly spreads from metal elements embedded in the walls to the entire surface of the gate.

Mechanized cleaning of metal from rust

Before you paint the garage door, you can clean the metal more the easy way- use simple tools:

a screwdriver and a brush attachment perfectly clean off dirt and paint residues, but the battery will be set to zero very quickly, and it will be problematic to use the tool again;
orbital sander - good alternative brush and sandpaper and is relatively inexpensive (up to 2000 rubles);
grinder (low power) with a metal brush nozzle. A soft version of the nozzle for the grinder, for old metal and paint - brass brush nozzles, for heavy pollution surfaces - brushes with interlaced threads.

Important. When working with a grinder, sparks and a strong emission of the smallest particles of paint are possible, therefore we work only in a mask and thick gloves.

The most expensive but reliable option for cleaning paint is sandblasting. To do this, you have to remove the gate. After sandblasting in specialized workshops, they offer a layer of paint in a special bath. The guarantee of strength and durability of such an update is 6 years, even under the most difficult weather conditions.

Chemical cleaning

The option is controversial, since after applying the solvent to the old paint and rust, the surfaces should still be cleaned of the old softened coating. Many users complain that after applying a rust remover and painting garage doors, they peeled off after three months.

Not surprising. Having softened the old layer of coating, they applied a new one. Therefore, after a while, two layers flew around together, because adhesion could not be achieved at all.

The best option for loosening rust and how to paint a garage door is Hammerite metal paint, there are also cheaper domestic counterparts. But, before applying, all the same, the peeling remnants of the old coating must be cleaned and degreased.

If the gate is new, still covered with grease, then you must first remove the layer of grease with white spirit, then rinse with acetone. It is not difficult to check the quality of degreasing - we apply a sheet of thin paper to the surface - if not greasy spot, then you can paint.

Rust neutralizer

Advice. Be sure to clean all the glossy and smooth details of the gate by grinding so that the surface becomes rough, then the adhesion of the paint to the metal will be more reliable and stronger.

Rules for painting and applying a chemical remover of old paint and rust, to the final coat:

We apply a reagent on the mechanically brushed surface of the gate. Washes in the form of a gel are better and more effective, as they have a higher covering power;
cover the surface with polyethylene - this will speed up the process of dissolving the paint;
we expect about half an hour (you need to follow the instructions, which indicate the exposure time of the wash);
with a spatula, remove the swollen softened old coating;
sometimes it is necessary to use the wash again;
before painting the cleaned Garage Doors you need to degrease the metal with kerosene and apply a layer of primer against rust.

Delete powder paint from a metal surface is easier. In this case, special detergents based on surfactants and mineral reagents.

The surface is cleared, now you should choose the right one good material for painting.

Choice of paint and primer for garage doors

Pigments that affect rust.

Garage door paint must meet certain requirements:

good covering ability of paint;
enhanced adhesion on a metal surface;
should not contain components that oxidize the metal;
high resistance to moisture and good water-repellent characteristics are required;
the elasticity index must correspond to paints for metal so that it does not crack at high temperatures;
thermal range of use for painting - frost resistance and heat resistance;
resistance to aggressive chemicals– gasoline, solvents and technical oils;
high resistance to impacts and mechanical wear.

Which garage door paint ideally matches the above characteristics:

organosilicon enamel - high strength and elasticity of the paint, with excellent resistance to moisture and long service life. The adhesion to metal of these garage door paints is excellent, the covering power is uniform. All silicone enamels have anti-corrosion properties.

Advice. This paint can be used to paint garage doors that are constantly exposed to direct sunlight, especially in southern regions countries. The coating withstands temperatures up to 600 degrees without changing color and durability.

alkyd enamel - high elasticity and durability, suitable for interior and exterior finish, big choice colors. Alkyd-urethane enamel - reliable a budget option paints for any garage doors;
hammer paint - resistant to corrosion, you can not clean the surface to the ideal, no need to primer, excellent dirt-repellent effect. It is better to apply from a spray gun under pressure;
acrylic enamel is an ideal, easy-to-use solution. best paint today, can be used for any garage door. Has everything required characteristics- withstands a sharp temperature drop, is not afraid of moisture and aggressive substances, is resistant to any atmospheric phenomena and high temperatures. The color palette, although small, is rich and deep. The only negative is the high price.

Important. When choosing what paint to cover the gate with, give up oil paints, they will crack very quickly.

For a metal surface, craftsmen advise using fire-retardant coatings "Polysteel" and electrically conductive dyes from ZINGA. This is special paints designed for auto repair shops and other special garage operating conditions.

Brands of popular domestic and imported paints for metal

primer-enamel "SPETSNAZ XV-0278" Yaroslavl paints, on rusty surfaces;
hammer Hammerite, dark brown color, should dry and polymerize for three weeks, then I cover the second layer;
Alpina Direkt auf Rost can be applied over rust. Must be fully cured to coat a second time. Color - white, black and silver;
you can choose Kuzbass-lacquer for metal surfaces, one layer is enough;
the entire line of materials for metal "Smile" - beautiful view and resistance to high humidity;
"Dufa" hammer, for metal, can be applied with a brush, the view is excellent, but it must dry for two days to paint again.

When choosing a paint, a lot depends on the condition of the gate and, of course, financial capabilities. Some simply dilute the silver powder and coat it on the most inexpensive primer, but it looks like a very expensive elite coating.

Primer

We offer several interesting proven options for a primer that must be applied before painting a garage door:

ship minium is a reliable and inexpensive solution;
silver - it is used when priming a car body before. Gives a metallic and pearly tint to any paint. It is cheaper and better to choose a simple option - buy aluminum powder separately and dilute it with drying oil. Coating - in one thin layer;
phosphating primer VL-02;
use minium metal;
primer for metal GF-021.

We prime only on previously cleaned and degreased dry metal surfaces.

Color selection

The color of the gate depends only on the preferences of the owner of the garage, what paint to cover. But, it must be taken into account that dark colors attract heat from the sun, and light colors reflect. Most popular colors- dark green, brick, light blue and burgundy.

Sequence of work

Garage door painting – necessary tools:

spray gun - the most convenient option, allows you to apply the coating in an even layer, without streaks, reduces paint consumption;
roller - leaves stripes that need to be rolled several times;
a brush is the worst solution for applying paint, there will always be streaks and streaks. Consumption is doubled;
respirator and gloves.

How to paint the gate in the garage - we act in sequence:

all surfaces that should not get paint are sealed with masking tape, ordinary adhesive tape is also suitable;
all paint and primer applications start from the top, moving down. This will eliminate streaks and sagging;
so that the transitions are not visible, overlap one parallel layer with another. This will ensure uniformity of color, without sharp color transitions and shades;
now you need to wait until the coating layer is completely dry and carefully inspect the surface. There are always areas that are missed, we paint them again;
paint all hard-to-reach places - hinges, grooves, latches with a thin contour brush so that there are no pieces of open metal left. Such surfaces provoke the rapid spread of rust;
any paint dries for a day;
The second layer is applied only after the first has completely dried, not before. Otherwise, the coating will quickly bubble and crack.

Advice. Do not apply more coats of paint than required, as excess weight coating reduces durability and strength. Two layers is enough.

Temperature regime

It doesn't matter how you paint your garage door, but the temperature and weather in which you will work is very important. Best temperature regime from ten to twenty degrees Celsius in calm weather.

It is desirable that at the time of work there was no direct sunlight, which heats the metal very quickly. If you do not pay attention to the temperature, then there may be unpleasant results:

rapid swelling of the coating, since adhesion decreases on heated metal;
the color will be uneven and dull;
there will definitely be streaks and streaks.

The ideal time is cloudy weather and a temperature of +12 - +15 degrees.

By choosing the right coating option and following the entire sequence of work, it is quite possible to inexpensively and beautifully paint the garage door yourself. The main rule is that you cannot paint on an old peeling coating and on rust, it is contraindicated to use oil-based paints. Priming is a must.

Metal structures are found everywhere. AT country house This metal fences, forged fences, forged railings and forged canopies. In a city apartment, we install wrought iron bars on windows, wrought iron elements on a balcony or loggia. Is it possible to paint forged products? Many people are sure that it is impossible and consider this the main drawback of such metal structures. But this statement is fundamentally wrong. Forged products can and should be painted in order to avoid rust in the first place.

Rust causes metal structures, forged products a huge, sometimes irreparable harm. Corrosion not only worsens the appearance of products, it reduces their strength, and in some, especially advanced cases, it can completely destroy them. Protect metal constructions and forged products from the harmful effects of rust can only be special compositions.

Very often in order to protect forged products from aggressive influences external environment, metal galvanizing is often used. This method is considered one of the most reliable methods protection of metal structures. Galvanizing is done by welding a zinc coating to the metal. Zinc melts and protects wrought iron railings, wrought iron gratings or wrought iron visors as long as its anodes are working.

But this method has one big drawback - the lack of visual appeal. Special forge paint can give the necessary decorative effect to the product, but it is possible to paint a forged product only six months after galvanizing.

Special blacksmith paints are made taking into account the features inherent in forged products. As a rule, blacksmith's paints have increased adhesion, moisture resistance, and resistance to any weather conditions. A forged product coated with such a composition is not afraid of rain, wind and snow, such paint does not fade in the sun, and most importantly, it protects the metal from corrosion.

High-quality, and, of course, expensive blacksmith paints do not lose their brightness and freshness for years, pleasing the eye with brilliance and juicy shades. A variety of colors inherent in blacksmith paints make it possible to enrich forged products, to make forged elements more expressive. But still, the main function characteristic of blacksmith paints is the protection of metal structures from corrosion.

What causes corrosion? As a rule, electrochemical processes that occur on the surface of a metal structure are to blame for this. And an indispensable participant in any such process is water. It can get on the metal during rain or condense from the air. In order for corrosion to fail to attack the forged product, this reaction must be stopped. And the easiest method is to isolate the surface forged items from contact with moisture using a coating with a special composition.

There are two ways to paint metal structures - modern and classic.

Classic way

In this case, special primers are usually used, which can be divided into phosphating, passivating and designing. Phosphating primers form a special film on the surface of metal structures, consisting of iron phosphates. Passivating soil compositions bring the metal surface into a passive state, oxidizing it. The composition of the protective primers includes zinc dust, which has a higher reducing ability. Thus, zinc acts as an anode, which protects the forged product, destroying itself. Insulating primer compositions create a dense coating on the surface of a metal structure that does not allow moisture to pass through.

All of these compositions have good adhesive properties. But their main drawback is that they have low wear resistance, which requires another appropriate composition to be applied on top. In addition, such primers are characterized by low decorative properties.

The classic coloring method implies a certain order of operations:
- removal of traces of rust from the surface of the metal structure, as well as old paint;
- transformation of corrosion into a composition that will protect the surface of the metal structure;
- application of a primer;
- application of decorative and protective composition;
- surface protection with an additional special compound.

When choosing a primer composition, it should be remembered that there are primers only for interior work, for example, Grepp Grundfarg from BECKERS. But the primer Metallprimer from the same company is intended, on the contrary, only for outdoor work. But the vast majority of companies produce universal primers that can be used in any conditions. The most popular primers are from companies such as CAPAROL (Capacryl Haftprimer product), OIKOS (Novalis Aggrappante composition), TIKKURILA (Rostex Aqua composition).

Alkyd enamels, such as BECKERS ("Hammarlack Hammer enamel"), MEFFERT (Hochglanzlack) CAPAROL (Capalac Seidenmatt-Buntlack and Capalac Hochglanz-Buntlack) , and etc.
Recently, water-soluble acrylic enamels have been used very often, for example, Novalis Smalto enamel from OIKOS is especially popular.

Modern way

Recently, more and more often, manufacturers offer to use universal compositions that perform several protective functions as protection for metal structures.

Rather than buying paint and primer separately, it is more convenient to purchase both of these compositions, as they say, "in one bottle." Such paints can be applied as a primer, and can be applied directly to rust. The service life of such products is at least 10 years. 2 in 1 compositions are offered by both domestic and foreign manufacturers, such as Metallgrund & täck from BECKERS. This alkyd paint can be used on wrought iron railings, metal fences, forged peaks and other forged elements.

special attention deserve special blacksmith paints WS-Plast, which are offered in a wide range by the German manufacturer WEIGEL + SCHMIDT LACKCHEMIE. Such compositions can cover any surface, including those that were previously painted. The coating in this case will serve at least 6 years. Average consumption - 120-130 g ha 1 sq. m.

WS-Plast paints are produced on the basis of adhesive synthetic materials, forming a high-quality decorative coating that is resistant to abrasion, exposure to sunlight, as well as to sudden changes in temperature.

WS-Plast paints are best applied to the surface of metal structures using electrostatic painting. The composition of WS-Plast Dickschicht M 4200 with zinc content provides decorative protection for several decades.

With the help of the composition WS-Patina, produced by the same company, a forged product can be artificially “aged”, giving it the effect of a copper, silver or gold coating.

The Belgian company ZingaMetall produces an unusual composition - Zinga, a one-component product that can be immediately applied to any metal surface. The peculiarity of this composition is that it contains electrolytic zinc powder, which forms a special thin film on any forged product - whether it be a forged railing, a forged fence or a forged gate with a gate. It provides both electrochemical and mechanical protection from rust, which affects all metal structures. The manufacturer guarantees that the service life of such a composition is from 10 to 50 years, depending on the thickness of the film.

In addition to “two in one” compositions, there are also “three in one” paints that combine the properties of a corrosion converter, a primer and decorative coating. The most well-known manufacturer of such compounds in Russia is the English company HAMMERITE. Paints of this company are distinguished by ease of application and quick drying - only an hour and a half. In order for the coating to serve for a long time, forged products must be coated with a layer of at least 100 microns thick. The service life of such a composition does not exceed five years.

If you plan to paint forged products in several layers, consider an important factor: after 8 hours, the coating begins to polymerize, and a new layer can be applied only at the end of this process, that is, after 2 weeks.

Similar compositions are also offered by other foreign manufacturers - SENTAPOL - Hammer Paint, MEFFERT - Correx product. NOVA paints, such as the two-component Novax composition, or the Novax anti-corrosion alkyd enamel, specially designed for forged products that are operated in an aggressive humid environment, have gained no less popularity.

Metal forging has always been considered a heavy and revered art. It is art, since it is one thing to simply weld two pieces of iron to each other, and it is quite another to make something beautiful and pleasing to the eye out of this.

But to create a real masterpiece, the skill of one blacksmith is not enough, the finished product still needs to be painted, and we will talk about how and with what it is better to do this in this article.

Someone might say that painting a forged product is no different from painting, for example, a wooden countertop, but this is far from the case. Firstly, these are of course special paints, which will be discussed below. And secondly, the method of painting, especially if there is a need to do painting work with your own hands, but there are no skills in this matter.

Interestingly, with the wrong approach, even the most expensive and high-quality paint will be powerless to protect the product from corrosion.

If we talk about the methods of painting, then they can be very diverse:

Brush.
Spray gun (see).
Tampon.
Dipping.

Important! When working with an airbrush, it should be remembered that the thicker the consistency of the paint, the harder it is for it to spray and the more pressure must be set on the compressor.

But you should always remember about difficult places, which are always abundant on forged products. For example, these can be places of welding, the fact is that during the forging process, the metal is exposed to strong heat and weakens by itself, and welding burns even more protective film, which is always formed on the surface.

It is in the places of welding that corrosion begins in the first place, and from there it diverges throughout the product. Another important nuance, which should be remembered is the cleaning of the product, no, not from possible rust, since three-in-one paint for forged products can safely cope with it, but to clean it from scale and metal delamination.

Cleaned and ready for painting

The fact is that at the moment of calcination, inhomogeneous parts of the metal begin to flake off, upon a cursory examination, this may not be noticed, but it is enough to carry out finished product with a metal brush, as soon as particles resembling scales begin to fall off.

Cleaning with a metal brush is also necessary if the product has already been painted, and now you just need to renew the coating. Paint for metal has a very high adhesion to the surface to be painted, but it can peel off the old coating.

Forging paints

A game of color contrast, looks perfect on wrought iron gates

If the question of how to paint forged products yourself is more or less clear, then what paints to use, this question is much more complicated and extensive. If you do not pay due attention to it, then you will have to repaint the product annually, especially if it is located on the street.

Today, there are a lot of paints specialized on metal (see), and each of them has its own unique set of qualities, and such a variety only confuses an inexperienced person even more. We will not dwell on the entire range presented in modern hardware stores.

And let's talk only about the most popular and, as a result, high-quality materials designed specifically for metal surfaces, taking into account the fact that the product will be used outdoors and constantly exposed to negative effects.

hammer paint

Hammer paint, or hammer effect paint (see) is so named for the similarity of the coating to the ruts from hammer blows to metal. The embossed surface of the paint perfectly hides all the small flaws and flaws that inevitably occur on a forged product, especially if we are talking about real hand forging, and not about stamping on machine tools. Instructions for applying hammer paint involves working with any convenient tool.

It can be:

Airbrush.
roller.
Brush.
Tampon.

It all depends on personal skills and preferences, the quality of the coating will not suffer from this at all.

Important! Hammer paint, very thick, and even working consistency material may not be amenable to a simple electric spray gun. Therefore, if it is not possible to use a compressor, pneumatic tool, then it is better to use simpler and more affordable methods.

Pros:

High degree of adhesion to metal.
Three-component paint does not require an additional layer of primer.
The polymer coating is completely resistant to water and sunlight.
Durability. A product covered with hammer paint does not need to be updated for many years.
Large selection of colors.
High resistance to mechanical damage. The hammer coating is very difficult to damage, even with heavy or sharp objects.

Unfortunately, even this material has several disadvantages that must be considered when choosing hammer paint as a coating.

Minuses:

The relatively high price, which, however, is more than offset by the durability of the paint.
Large consumption of paint square meter, especially when working with a spray gun.
If it is necessary to repaint, hammer enamel is very difficult to remove, and another coating does not lie on top of it.
Hammer paint is presented in a very wide range color scheme, but despite this, if not picked up required shade, there is no way to use color paste.

As you can see, the minuses of hammer paint are less significant and are fully offset by the pluses, but they exist, and this imposes a number of restrictions on the use of this material.

blacksmith paint

On the picture, special solvent for blacksmith paint

Painting forged products with blacksmith enamels is considered the most durable and high-quality. To date, paint of this quality is produced by only a few European companies, and, accordingly, the cost of this material is simply sky-high.

But considering that the manufacturer himself gives a minimum warranty period for his products of 25 years, the price becomes much more attractive. The peculiarity of this paint is that it consists of stable polymers, and outwardly it may resemble ordinary bitumen, but this is not so, forge enamels are not only much more stable than mastic, but also have a shine characteristic only of oil dyes.

One more interesting feature blacksmith's paint is that it dries very quickly and even at low temperatures. This makes it possible to paint the product right on the street and not be afraid that the coating will spoil the rain or unexpected frosts.

Even a well that is in constant contact with water can be painted with blacksmith's enamels.

If we talk about the minuses, then in addition to the high price, we can single out the need for a mandatory preliminary layer of soil, which must necessarily be of the same brand as the paint itself. Otherwise, the manufacturer automatically disclaims all warranty obligations regarding the durability of the coating.

Interesting! If financial opportunities are limited, then you can simply use the forging soil, and apply on top of it regular paint PF. In this case, all the characteristics of enamel increase several times, although the result of 25 years is unlikely to be achieved.

And in order to clearly understand how to work with blacksmith paints with your own hands, you can watch a video that clearly shows all the stages.

Paints ML

Paints ML for painting cars

Enamels under this brand - attempts domestic manufacturers create a kind of hammer enamel. Unfortunately, their quality is much inferior to foreign analogues, but their cost is much lower.

Outwardly, this paint resembles ordinary PF, but unlike it, it has higher technical specifications including durability and resistance to mechanical damage.

The gate guarding the car in the garage or the entrance to the yard need regular maintenance and restoration. Door painting is done not only for aesthetic appearance. It is important to protect the metal from destruction due to corrosion. It is necessary to choose the right paint and make the preparation of iron sheets and forged elements. At the same time, an original look of the gate is created with their own hands.

Scale and rust on iron gates

The word "gate" itself means that the structure is outdoors under the influence of moisture and temperature changes. It protects against illegal entry into the garage and yard. Therefore, the gate must be strong, easy to open. They need to be looked after: lubricate the canopies, cover protective compounds the entire surface.

My friend built his house and the next summer came to me with the question of painting the iron gate. During the year they all lost their attractive appearance, began to corrode. The paint was flaking along the edges and at the joints. Restoration required different designs:

sheet steel garages;
forged at the entrance to the yard.

Vadik wanted to do everything with his own hands. I told him the main stages of painting the gate:

Clean the structure from dust and dirt, wash it well and dry it.
Remove rust.
Degrease the entire surface.
Coat with metal primer.
Apply fresh exterior metal paint.
Decorate the gate if desired.

Each of the operations can be simplified by using special tools and tools. discussion various options my friend and I got busy.

Sheet metal garage doors

Vadik brought a garden hose with various attachments. First, he washed off the dust and debris with a jet of water. Then I sprayed the cleaning solution. Gates made of sheets had practically no transitions. With an ordinary brush, they walked with him on all planes, washing off dirt, oil stains.

The weather was good. The water with which we washed off the remnants of the solution quickly dried up. Then we had a competition. Vadik cleaned one leaf with a metal brush. The second I cleaned with a drill with sandpaper nozzles.

The dust was removed with a vacuum cleaner. They didn’t bother with the manual method with a whisk and a sponge. My friend is tired brushing.

The primer for metal was applied with their own hands, with brushes. Carefully brushed:

places of welding;
around awnings, handles, lock;
ends;
sheet joints.

Covered the entire surface. In places of doubt, walked twice. Don't forget the pens. The whole surface was completely dry only the next day. Painted with hammer paint. Used a spray gun.

The walls around the gate were covered with foil. We don't need paint. Sheds were greased with grease. Opened and closed several times iron gate. Then the excess grease was wiped dry. The lock was sealed with tape.

Difficulty cleaning forged elements

The forged gate at the entrance to the courtyard had many twisted and bent elements with large quantity hard-to-reach places. They were near the road and were heavily splashed with mud by passing cars.

If possible, washed them first with a strong pressure of water from a hose. Then the cleaning solution was sprayed. Attached to the drill round nylon brushes. Our wives wash such jars inside. Removed almost all dirt. The rest was removed with water.

Inhibitor and modifier will make it easier to clean the gate

Quickly paint the iron gate

They did not sand the rust in the gate structure with a large number of hard-to-reach places. Vadik asked me to tell him about other easy ways to clean corrosion with your own hands. I took out a pre-purchased two-component anti-corrosion compound from the trunk:

the modifier enters chemical reaction with iron oxide, and changes its formula to inactive;
the inhibitor suppresses the processes of connection with oxygen and the formation of corrosion.

The two substances are packaged in different containers and are mixed immediately before use.

After applying the rust modifier, Vadik went over all the surfaces with his own hands with a round metal brush, called the “witch”. He fixed it on a drill and set it to medium speed. For cleaning complex design a metal gate my friend spent a couple of hours.

hammer paint

We produce high-quality painting of iron gates

We covered the base with hammer paint. The two actions could be combined. On sale there are paints, which include modifiers and inhibitors. After application, the surface has a glossy appearance. But in places severely damaged by corrosion, rough spots remain.

Iron gates can be painted with different colors:

nitro enamel dries quickly, but is aggressive to all other materials and does not last long;
oil under the influence of moisture quickly collapses and ceases to protect the metal;
alkyd resistant, but emit toxic substances;
acrylic is unstable to temperature fluctuations and loses its appearance;
hammer has an original appearance, resistant to moisture.

We settled on hammer paint. The silicone resin base makes it flexible. She gets into the cracks. Metal pigments and synthetic fibers, after drying, form a solid film on the surface with a pattern of small stains. It can cover even iron that has not been cleaned of rust.

High paint fastness is used in the machine tool industry. There it withstands not only water, but oils, emulsions, hot chips. Appearance kept for several years.

Imitation of different types of forging

For decorative design Vadik and I used paints imitating a textured, forged surface. They were called molotov. They have a golden and silver hue, are yellow and white.

Having picked up the colors according to the theme of the drawing, my friend and I began to paint curls and spirals with thin brushes. Vadik decided to turn the gate into an element of architectural decoration.

Why is it necessary to paint metal products and why do it at all? After all, this is a strong and hard-to-wear material, and, for example, new garage metal gate already painted. Is it just for beauty? Answering these questions is required to understand the actions to preserve metal products from corrosion.

Identification of the need for staining

metal gate country house, both garage and entrance are used daily, which is necessarily reflected in their canvas. However, they are installed outdoors. And on the metal structure located under open sky, temperature and humidity affect, eventually leading to corrosion of the product.

Rusted canvas gives the gate an unaesthetic appearance. This indicates not only the influence of natural factors, but also the improper preparation of the surface for painting. Therefore, it is necessary to pay attention to the process of preparing and painting metal products.

The need for painting is determined visually. This is not only clearly visible rust, but also the presence of internal corrosion, which leads to the appearance of small bubbles on the surface and further flaking, as well as peeling of the paint. If the preparatory work is done with high quality, then the next painting will not be required soon. It will only be necessary to periodically tint, or rather, refresh.

Paint selection

When choosing a material for outdoor work, certain requirements should be followed. They are dictated by the need for a long period of preservation of the surface from external factors. Here are the properties that the selected paint and varnish products should have:

good adhesion to the surface (adhesion);
sufficient elasticity, since expansion and contraction are the response of metal products to temperature effects;
the presence of water-repellent properties;
possibility of use in a wide range of temperatures;
resistance to chemically active substances;
strength under mechanical stress.

When choosing a paint and varnish product, it is necessary to take into account all the points of this list. After all, iron gates are used in various conditions. They may be affected not only by temperature and moisture, but also by mechanical stress or accidental ingress of oils and other chemicals.

Knowing the requirements for paints for outdoor work, you can proceed directly to the choice. Available for sale big variety paint and varnish products, the cost of which varies widely.

The most used types are as follows:

Nitro paint is quick-drying, which makes it easy to use. However, it peels off, and then, within six months, it peels off. Not recommended for use over other types of paints and varnishes.
Oil. Allows you to cover the product with a thick layer, but dries for a long time. Depending on the company that produces the goods, the drying process can last from a day to a week. For such a long time, small particles stick to the canvas, which reduces the attractiveness of this type of paint.
Alkyd enamel - universal, has good resistance to abrasion. There is a wide range of colors and a choice of textures - the usual glossy or matte. The durability of the painted surface is from 3 to 7 years. Drying time - within a day.
Acrylic enamel - well withstands sudden temperature changes and exposure to moisture, as well as aggressive substances, is elastic. Received wide use in use.
Silicone enamel - has good adhesion, is durable and elastic. Particularly distinguished by heat resistance, anti-corrosion properties and low consumption during painting.

Choosing a coloring tool

This is an important moment in the production of paint work. The right approach is needed to preparatory work, and to the coloring of the gate. Which tool to choose is an independent process, depending on specific conditions and circumstances. An important factor here is the professional level of the worker.

Roller, brush and spray gun - the tool you need to do the job. Paint only with a brush, ineffective due to the appearance of streaks on the working surface. The work will have to be done again. It is impossible to paint with a roller in corners and narrow places. Therefore, their combined use is recommended.

The spray gun can only be used by a person who has the skills to work with it. It requires not only a timely change in spray pressure, but also the knowledge of what viscosity the paint must have in order to paint the gate. Lack of skills will lead to strong streaks over the entire painted area.

Preparatory work

Preparation for painting the gate must be carried out in strict sequence. It is necessary to perform the following work steps:

Washing or cleaning from dirt. The removal of contaminants is carried out, as well as the washing off of other substances adhering to the canvas. The most thorough work can be done using a hose. Pay special attention to corners and hard-to-reach places.
Surface cleaning. At this stage, it is necessary to remove peeling paint from the canvas. If the layer of the previous coating is large, then it is necessary to remove the entire thickness of the old stains. Works can be carried out both with a metal brush and building hair dryer. It is possible to use a grinder or a drill with a special nozzle - a “brush”.
Grinding. Produced sandpaper fine-grained structure, regardless of the way the work is done - manually or using a drill, which has a special nozzle. The mechanized method speeds up the work. However, without the use of manual grinding is indispensable in hard-to-reach places.
Degreasing. It is carried out with a solvent after cleaning and grinding. It is important to process the entire surface without gaps, not forgetting about hard-to-reach areas. It depends on the quality of the coupling. further coatings with metal.

Of course, changes and additions to the order of work are possible. Some gate owners wash after stripping and grinding, using detergents. This allows you to save on degreasing agents. But it should be remembered that these works must be carried out very carefully, and detergents cannot replace the solvent.

Carrying out painting work

You can paint the most evenly with a spray gun. The work is done quickly and efficiently, with coloring of all hard-to-reach places. You should be careful not to get small drops of paint into the respiratory tract, which fly in the form of a suspension in the surrounding space when working with such a tool.

The most common way to paint is to use a roller for large areas and a brush for hard to reach areas. It is necessary to carry out painting work from above, gradually falling down. Apply paint in parallel lines that overlap by a few centimeters.

After painting is completed, it is required to evaluate the integrity of the work. To do this, move back a few meters to identify gaps and other defects. Paint over the found areas with a brush.

If the color of the paint after drying turned out to be dull, then a second layer is required. Work is performed in the same sequence - from top to bottom. Multiple layers can be applied to achieve bright color painted surface.
