Putty "Knauf uniflot" - description, application, cost. Knauf uniflot (25kg) high-strength gypsum putty

Special putty for seams Knauf UNIFLOT is designed for sealing joints drywall sheets and panels based on them (panel finishing elements, perforated and slotted panels).
When using UNIFLOT putty, butt joints are sealed without the use of reinforcing tapes. Particularly recommended for sealing transverse joints of drywall sheets (chamfered edges).
Designed for sealing joints of KNAUF gypsum boards (GKL), KNAUF super sheets (GVL), KNAUF superfloor (floor elements from GVLV) and perforated KNAUF-Klineo boards.
When using a mixture of Knauf-Uniflot, butt joints of sheets with a semicircular thinned edge (PLUK) are sealed without using a reinforcing tape.

Designed for interior work.

High-strength gypsum putty KNAUF-Uniflot surpasses all similar materials in its technological and technical performance. Particularly effective when sealing transverse joints of Knauf plasterboard sheets.
Does not crack and does not shrink. The material is made of environmentally friendly natural mineral (gypsum) and does not contain substances harmful to human health.

Surface preparation
Knauf sheets must be firmly fixed to the supporting base (framework).
When puttying plasterboard joints formed by chamfered cut edges, treat the edges with a KNAUF-Tifengrund primer.
Allow the primer to dry after application (min. 3 hours). Avoid dusting the primed surface. When puttying plasterboard joints formed by longitudinal unedged edges, clean the surface of the joints from dust without moistening.

Solution preparation
Pour the dry putty mixture into a container with a clean cold water, evenly distributing over the surface until dry "islands" appear (approximately 1 kg of putty per 0.5 l of water). It is not necessary to leave to swell. Stir with a spatula-trowel until a homogeneous creamy consistency is obtained, without adding more dry mixture.
The water temperature for mixing the dry mix should be between +5 and +30 °C. More warm water impairs the water-retaining capacity of the putty and can cause cracks in the putty.
It is not allowed to add other components to the putty mixture, as this leads to a significant deterioration in its properties! Do not use a thickened putty solution, adding water and mixing do not restore its working properties.
Contaminated containers and tools help to reduce the duration of the possible use of the material.
The duration of the preservation of the working properties of the putty solution before thickening is at least 45 minutes.

Work order
The sequence of operations when forming a joint:
- application of the first layer of putty
– laying the paper reinforcing tape on the putty layer by pressing it with a spatula, while avoiding the formation of wrinkles and bubbles
- applying a leveling layer of putty on the hardened and dried first layer.
When sealing the joint formed by the edge of the PLUK, the reinforcing tape is not used. Puttying is carried out using a spatula with a width of ~ 150 mm, preferably with a handle adapted for screwing protruding screws, which allows you to quickly eliminate possible problems during puttying.
installation defects.
It is recommended to work with a wide (20 cm) spatula with a screwdriver on the handle. Fill the joints by pressing the material with a spatula. After a short exposure (after about 50 minutes), remove excess material in places where thickenings appear and smooth down. Places of installation of screws also puttied in 2 passes.

Recommendations
After the putty has hardened and dried, remove the unevenness with a grinding tool (grater with a sanding net). For high-quality painting on the puttied surface, apply a layer finishing putty, for example, Knauf Rotband-Finish, Knauf Multi-finish, Knauf
Rotband-Paste or Knauf Multi-Finish Paste.
Before application decorative coating(paint, wallpaper, decorative plaster) Treat the puttied surface with a KNAUF-Tifengrund primer.
When facing ceramic tiles surface areas of Knauf-sheets that are exposed to water require the application of Knauf-Flachendicht waterproofing. All tools and containers used in the process of work must be made of stainless materials. Equipment and tools should be washed with water immediately after completion of work.

Application area

KNAUF - Uniflot - a special putty for seams, designed for sealing joints of Knauf-sheets (GKL) and panels based on them. When using Uniflot putty, butt joints of sheets with a semicircular thinned edge (PLUK edge) can be sealed without the use of reinforcing tapes.
The use of Uniflot putty is especially recommended when sealing transverse seams of gypsum boards, where there is no thinned edge. In this case, it is necessary to cut the transverse seam at an angle of 22-45 degrees. (See Planer for GKL)

Solution preparation

Surface preparation
Sub-base surfaces must be sound, firm, load-bearing, clean and dry.
Material consumption
The consumption of dry mix per 1 m2 when puttying plasterboard joints and screw installation sites is:
for ceilings 0.3 kg;
for partitions ~~0.5 kg.
Operating procedure
The temperature of the base and the air in the room must be at least +10°C.
As a rule, puttying with Knauf-Uniflot is carried out in two passes. It is recommended to work with a spatula with a screwdriver on the handle and a wide (20 cm) spatula. Fill the seams by pressing the material with a spatula. After a short exposure (after about 30 minutes), remove excess material in places where thickenings appear and smooth down. Places of installation of screws also puttied in 2 passes. Seized material must not be recycled due to the risk of cracking!
Possible minor bumps can be sanded after drying.
All tools and containers used in the process of work must be made of stainless steel.
Equipment and tools should be washed with water immediately after completion of work.
Packaging and storage
Uniflot is packed in paper bags of 5 kg and 25 kg.
Seal the opened bag well. Store in a dry place - shelf life is approximately 6 months.

Technology for sealing joints on drywall sheets:

1. Apply a layer of putty with a spatula 50-75 mm wide on the joint formed by thinned-edge lined cardboard. Align the laid mass, at the same time removing excess putty.

2. Cut off the required piece of paper tape to the length of the seam. To increase elasticity, dip the paper tape in water and shake off excess water. Press the moistened paper tape with a spatula into the putty layer. The operation should be carried out immediately after applying the putty, before the start of the setting (hardening) process.

3. Using a spatula 150 mm wide, apply a covering layer of putty, carefully smooth the seam, removing excess putty.

Decoration Materials, it would seem, do not form the basis of the house, and therefore play a smaller role. But it's not. At the stage of puttying walls and surfaces, the inner beauty of the room is determined.

The evenness of the walls, the integrity of the seams and corners, and durability depend on the putty. decorative design and the comfort of the whole house. One of the highest quality putties that are sold on construction markets and in supermarkets - Knauf Uniflot.

Material Features

The purpose of the material is the formation of a flat and smooth surface, on top of which further fine finish. Also, the putty layer performs minor waterproofing properties.

Use as a leveling layer is relevant when there are minor surface drops, small chips or cracks. If there are big problems with the evenness of the surface, it is better to replace the material with plaster.

Knauf Uniflot is used everywhere - both for floors and walls, both in residential premises and in basements or attics.

This material is from well-known manufacturer mainly used on drywall

• Gypsum plasterboard sheets;
• Super sheets or gypsum fiber sheets GVL Superpol;
• GLVL floor elements;
• Perforated boards with edges, etc.

However, for any other surfaces, its use is also possible and also relevant. Can be used on wood and concrete surfaces brickwork, thermal insulation materials(styrofoam, polyurethane foam).

Uniflot putty is designed for indoor use only. She not only level and cover the walls, but also seal the seams, level the corners and even glue drywall sheets and slabs to flat surfaces.

High adhesion allows you not to experience any problems with surfaces glued to this type of putty.

Uniflot is sold dry, based on building mix- gypsum, it is supplemented with special polymer additives. Individual fractions of the finished and dry mix do not exceed 0.15 mm. traditional color the mixture is white, but on sale you can find colored putty (from shades of gray to pink).

The color is acquired by adding natural dyes, it does not change any characteristics. On the contrary, it gives the material new properties - decorative. Thus, if desired, plaster can also be used as a finishing coating.

By the way, in non-residential premises and various public buildings often do just that, simply finishing the walls with putty. Cheap, fast, practical and simple, and it looks beautiful.

Uniflot putty is applied easily, the maximum coating layer is 5 mm, the minimum is 1 mm. Material consumption depends on the type of surface, on average, 0.3 kg is spent on the ceiling, 0.5 kg / sq.m. on partitions. meter. This material is very plastic, vapor-tight and absolutely safe for health.

In the store you will be offered a dry mix in Uniflot Knauf 5 kg and 25 kg paper bags. The shelf life in this form is up to 9 months, provided that the packaging has not been broken.

Advantages and disadvantages

Among the analogues of putties, Knauf Uniflot is confidently in the lead. Due to its properties, this material is not only safe and easy to use - it has a number of undeniable advantages that make it one of the most purchased and sought-after compositions. In particular:

• does not shrink (which means it will not crack after drying, which is especially important for seams and joints);
• relatively easy to use (although it requires some experience);
• allows you to form a flat, uniform surface;
• is cheap;
• can be applied to almost all modern Construction Materials(including thermal insulation).

The material still has drawbacks, but they are not related to quality. This material requires a certain amount of experience, both when mixing and when applying.

How to apply?

Apply the material only on a dry and even surface, without oils and other substances complicating bonding. If you are renovating and not building from scratch, then paint or wallpaper should be removed from the walls and partitions. Although textured plaster is still used for this.

The mixture is diluted as follows: 2 kg of the dry mixture is poured into a liter of clean water and stirred until smooth. The “recipe” is general informational and does not encourage action - The right way cooking must be read on the packaging!

Remember that the mixture will begin to harden after 20 minutes - so you have a limited amount of time at your disposal.

This makes the application process less convenient if you want to cover large area(and this is usually the case with repairs). You simply will not have time to apply the solution to the surface of all the walls of the room (for example), and you will have to prepare it again.

However, this drawback is not too significant, and it takes a minimum of extra time. And in fact, almost all solutions from other manufacturers have the same properties, so you should not focus on this.

Now we will describe in stages how exactly the application of Knauf Uniflot will look like (and, in fact, any other putty):

1. The surface is cleaned from the old coating, dust and dirt.
2. Ideally, the surface is primed to improve the adhesion of the putty.
3. The solution is prepared in the required amount.
4. The application is carried out with a spatula (metal or plastic) - the solution is smeared with it over the surface, after which it is leveled with a plumb line.
5. The first layer of putty is recommended to be no thicker than 5-7 mm (again, read the instructions on the package).
6. Cracks, joints and chips should be treated several times.
7. After the layer has dried, it should ideally be cleaned with sandpaper.

The second layer (and subsequent ones, if any) is applied only after the previous one has completely dried. Then you can putty on the walls under the wallpaper and apply plaster on the wall.

The purpose of Uniflot Knauf putty and its characteristics

The technical characteristics of Uniflot (Knauf) putty, its purpose are determined by the composition of the material. The basis of the building mixture is gypsum. It provides the putty with ideal plasticity, which allows you to create an even layer, qualitatively close up irregularities, roughness, and depressions. The material is environmentally friendly, so it can be freely used in residential areas. Gypsum base does not provide a mixture high performance moisture resistance. Therefore, these building materials are used in interior work.

Uniflot Knauf putty is used in finishing:

• Ceilings
• Partitions
• sexes

The material is ideal for sealing joints between sheets and Knauf boards. In this case, reinforcing tape does not need to be used. Ready putty can be applied in layers of 1-5 mm. Consumption Knauf Uniflot per 1 m 2 when finishing partitions, walls is 500 g, when finishing ceilings - 300 g. The strength of the layer for bending is 2.7 MPa, for compression - 5.2 MPa. The material dries quickly, so the amount of the prepared mixture is calculated for 20 minutes of work. Thanks to high speed hardening of the solution, an hour after applying the first layer, you can proceed to the finishing putty.
