Major restoration of interior doors. Do-it-yourself interior door repair (photo and video) Do-it-yourself wooden interior door repair

Doors are a structure that is in any home and this structure is subjected to the strongest loads every day, and therefore it is not surprising that from time to time the doors break and fail. Of course, professionals can be invited to repair door structures, but their services are quite expensive, and therefore a zealous owner should be able to repair the door with his own hands. Consider the main types of breakdowns of door structures, as well as methods for repairing doors from different materials.

The main types of damage to door structures

To qualitatively and quickly repair interior doors, you need to study in detail the main types of breakdowns:

Pinching the door structure or sliding it on the floor surface. This problem occurs because the hinges of the product are loose or loose. Repairing the door in this case is quite simple - you just need to strengthen the screws in the hinges. In a more difficult case, the screws will have to be replaced with new ones, or the hinge fastening should be moved a little higher or a little lower.
The door sagged and scratched the floor. To eliminate such a malfunction, experts recommend rearranging the loops. You can try the following method: between the upper and lower hinges you need to place a washer or a wire ring and the door structure will rise when landing to the required height (see photo).
It is also necessary to repair the product if its material has dried out due to high humidity in the room. A cracked door needs restoration and, in some cases, it can be done by hand, but in case of severe damage, the structure will have to be changed.
The product may also require repair due to errors made in the initial installation. If the hinges are not installed correctly, the product may be pinched in the handle area. To eliminate such a defect, the door will have to be removed, and the hinges to be strengthened again.

We have considered the most frequent breakdowns of door structures, and now we can move on to a detailed review of the repair of doors made of different materials.

Repair work to eliminate breakdowns in MDF door structures

MDF is a material that is highly vulnerable to external influences, and therefore it is easy to scratch it. Is it possible to remove scratches from the door leaf with your own hands? Professionals assure that this work is simple and not costly in terms of materials. To repair an MDF canvas, you will need to prepare in advance:

Sandpaper with grit up to 200;
Special putty for wood;
Priming;
Enamel for wood;
Brushes.

To begin with, the MDF surface must be cleaned with sandpaper in the area of \u200b\u200bdamage. It is necessary to clean not only the place where there is a scratch, but also the space next to it. After the cleaned area is treated with putty and allowed to dry. As soon as the putty material dries, the door is sanded again with sandpaper. After that, everything is simple - first, a primer is applied to the door, and after it dries, enamel.

You can learn more about tips on how to repair damage to an MDF door structure by watching the video that you will find at the end of the article.

Features of repair of products made of veneer, chipboard, wood, fiberboard

The following problems are typical for door structures made of veneer, chipboard, wood and fiberboard:

Products made from these materials often crack due to high humidity in the room. Moisture causes wood sheets to warp or move along the box.
Due to shrinkage of the web, gaps may form;
Detachment of the top coat. This problem is often seen on veneered products;
Rotting, chips and other external damage to the canvas.

The owner can easily cope with some problems on his own, but it is better to entrust the repair of complex problems to professionals, especially if you have never worked with wood, veneer, fiberboard and chipboard before.

Fiberboard and chipboard - the materials are quite flimsy, and therefore, in the absence of experience, you can not repair the door, but finally break it.

Plastic doors break much less often. Plastic is a material that is quite resistant to external influences, and manufacturers put fittings on products of decent quality. But, nevertheless, the plastic door structure can also break. How to repair a plastic door without resorting to the help of specialists? Let's share some useful tips on this topic.

One of the most common breakages on plastic products is a loose handle. The handle is loosened because during the opening and closing of the structure, which occurs regularly, the process of unscrewing the fixing bolts is gradually going on. This unpleasant breakdown is easily fixed - you just need to tighten the bolts to the desired degree and the handle will stop hanging out.

It is even easier to adjust a sagging plastic sheet - it sags after prolonged use under its own weight. As a result, the structure begins to poorly, and open and close. You can solve the problem by twisting the loops - upper or lower. If the canvas has shifted horizontally, then you need to adjust the upper loops, if vertically, tighten the lower loops.

Much harder to deal with a broken lock. Consider the causes of breakdowns of the locking mechanism on the plastic sheet and possible options for self-repair.

How to repair the lock on a plastic door yourself

To begin with, you will need to remove the lock from the canvas and see which particular part of it is damaged. In general, if you are not an expert in locking mechanisms - do not disassemble the lock into parts, trying to determine what is wrong in it - just buy a new mechanism and install it on the door. And save time, and repair the door.

If you understand locks well enough and can identify a breakdown of a particular part, buy and change it, and then install the lock in its original place. A little advice from professionals: it doesn’t matter what exactly you will buy for repair - a lock or a separate part of it, it is important to purchase products from the same company that made the basic hardware for the door leaf.

Door restoration: how to fix a wooden structure

Old wooden doors are sometimes easier to replace than to repair, which is what many designers offer to do. But very often it is possible to repair wooden doors, so do not rush to change them - first try to restore them.

The reason for repairing an old wooden door can be both the loss of its original appearance and the problems that have arisen with its functioning. Many of the reasons leading to problems with the door are quite easy to fix with your own hands. Therefore, do not rush to save money for the purchase of a new product, first make sure that repairing a wooden door is impossible.

While the design looks good and does not cause problems with opening and closing, few people think of taking care of it (see. But from time to time, even the highest quality design needs preventive inspection and maintenance - lubrication and adjustment of hinges, cleaning, coating with special compounds.

If this is not done, one day you may find the following:

The door sagged and scratched the floor.
dangles on hinges, creaks.
does not close well, entering the box tightly.
On the contrary, it does not close, because large gaps have formed between it and the jamb.
The box itself wobbles.
The structure dried up, cracks appeared in it.
The panels do not hold well in the strapping.

Repairs may also be required when the exterior decorative finish is damaged - the paint has peeled off (see), the laminate is swollen, the veneer has peeled off, etc.

How to strengthen and repair the box

If you notice that the box does not hold well in the opening, you can fix it like this:

Remove the trims.
Align the box vertically and fix it in the correct position.
Drill 2-3 holes in the lock and hinge posts, deepening into the wall a few centimeters.
Drive steel pins or pins into the holes made from solid wood. Before that, they must be lubricated with epoxy glue.
Re-install trims, stepping back from the edges of the box by 1–1.5 cm.

How to fix: reinforcing the box

Attention! If the door is in a concrete wall opening, you will need to remove the box to drill holes in the wall with a puncher.

How to troubleshoot loops

If the structure is pinched in the upper part, touches the floor or threshold, does not close well or hangs on the hinges, it is most likely that it is not necessary to repair, but to adjust, replace or re-hang the hinges.

First, check that the top hinge is firmly attached and, if necessary, tighten the screws. If this does not help, it is necessary to deepen the recess in the strapping beam under the hinge plate. But first, if the door has not settled very much, try putting a metal washer or a ring made of wire (in the case of detachable hinges) on the hinge pin.

How to straighten: adjusting the door with a washer put on the hinge

Important! Hinges and washers must be lubricated with machine oil before hanging.

Sometimes the screws turn and cannot be tightened.

In this case, you can do one of the following:

Replace screws with longer ones.
Seal the holes for the screws by inserting matches into them.
Remove the hinges from the jamb, grease the holes for them with glue. Also grease the new screws with glue, let them dry and put the hinges back in place.
Rearrange the hinges below or above the previous attachment point.

If it's not the loops

Sometimes, even with a cursory examination, it becomes clear that the cause of the door malfunction is not in the hinges, but in violation of the geometry of the leaf. It can swell from high humidity or, conversely, shrink. And sometimes, after several stainings (see), too much paint is formed on the edge of the product and the folds of the box, which does not leave a gap between them. What to do in such cases?

Close the door tightly, if possible, and check for a gap. If it is not there or it is very small, it is necessary to clean off the paint or remove the product from the hinges and cut the strapping, ensuring that the gap around the entire perimeter is 2-3 mm.

Broken door: repairing gaps

If the door does not fit into the folds of the box at all, stand on the side of the porch, press it against the box and outline its gap with a pencil right along the canvas. Thus, you will get the correct contour of the door leaf and will be able to cut off the excess with the help of a planer.

Attention! Before planing the door, make sure that the frame is level and has retained its configuration: measure its angles and diagonals.

How to eliminate large gaps between the door and the frame

If the door was made from uncured wood, it may dry out and shrink during operation. And there is no passage at all. As a result, large gaps form between the canvas and the frame, the door begins to hang on its hinges, and the latch tongue does not reach the striker.

In such cases, repairs are also required, which is carried out by attaching strips of the required thickness to the edges of the door.

How to strengthen the panels

If the panels do not hold well in the strapping grooves due to the fact that the door has dried out, restoration can be done in two ways:

Reinforce the door with steel squares. They are attached to the strapping bars with screws on both sides.
Re-glue the strapping bars. To do this, the product must be removed from the hinges, disassembled and thoroughly cleaned of dirt and old glue. Then connect the bars together, lubricating the spikes with carpentry glue, insert the panels in place and place the structure in the clamping device.

How to repair cracks in a wooden door

Methods for repairing cracks and scratches depend on their size and depth. Below is a detailed instruction on how to repair the structure in such cases.

Attention! If the door faces the street, at least 2-3 coats of varnish must be applied to it to form a weather-resistant coating.

How to repair wooden sliding doors

The main reason for the repair is the poor performance of the rollers in the guide rail (see). This can happen due to the loosening of the mounting bar on which the guide is fixed, or due to unadjusted carriage mechanisms.

In the first case, the beam must be strengthened in approximately the same way as the box. Second, adjust. Sometimes it is enough to put locknuts under the adjusting bolts.

We hope that our article will help you to repair wooden doors in accordance with all the rules.

Most of the defects in the inner door frame are easy to fix. the biggest difficulty that lies in wait for the master is the dismantling of the canvas and correcting the shape of the box. Other types of repair work are more likely to be cosmetic in nature, and they do not require special skills.

Types of failures and damage

All types of internal door malfunctions are divided into two categories: a damaged product appearance and improper functioning.

To correct defects in the decorative cladding, a reconstruction of the canvas will be required. Such work is carried out in the same way as for the restoration of cabinet wooden furniture.

Door malfunctions are expressed as follows:

The sash closes unsatisfactorily and loosely, as a result of which rubbing occurs on the floor. It is required to repair the hinges and adjust the position of the canvas;

Important! When the sash often comes into contact with the box, you need to set the position of the leaf relative to the frame.

Uneven clearance around the circumference of the porch (slits appear on one side, and on the other, the cloth rubs against the box);
Sagging sash. This deformation is caused by its own weight. If the deformation is not corrected for a long time, this will lead to a skew of the box;
When the canvas moves, a creak is heard. In this situation, you simply need to lubricate the hinges. If the creak has not gone away, in this case it is worth checking the frame for skew;
The door doesn't swing open. If the humidity is high in the room, this negatively affects the door frame. From moisture, the frame is deformed, and distortion occurs. A breakdown of the locking device can also lead to such a malfunction.

Sometimes a particular type of door deformation becomes the result of several factors, so you need to consider all the options for problems that arise with the doorway and be able to fix them yourself.

Causes of defects:

Incorrect door installation;
Poor-quality or weak loops for a heavy canvas;
Wear of the loops or deterioration of their fixation;
Shrinkage of the building;
Weak fixation of the box in the doorway.

Important! If the problems are related to a malfunction of the hinges, it will not be difficult to repair the door. It is much more difficult to correct the errors made during installation or to eliminate the consequences of shrinkage. You have to re-mount the box and canvas.

How to fix a door frame

The most difficult breakdown is the deformation of the door frame; it is not always possible to fix it on your own, since you have to completely redo the frame.

Important! If the damage is not eliminated, then soon the canvas will shift diagonally, begin to rub, and with prolonged and intense pressure, the stand may also be deformed. This is fraught with repairs not only to the door, but also to the walls.

How to align and adjust the door frame after installation

To repair the inner door frame, you will need to remove the panel from the hinges. Next, measure and designate the place where the displacement occurred. To determine the sag, you need to check the diagonal.

Remove the decorating elements from the door structure and screw additional bolts into the leaf. Such manipulation will help to fix the structure more firmly in the correct position.

The old mounting foam will need to be removed and the spacers wedge in.

Using a special knife, get rid of the old layer of foam

After this work, the structure can be foamed.

Re-foam the box

Restoration of the inner door frame

Restoration work is carried out without removing the door. This is not required for puttying and masking scratches formed on the surface.

One of the simplest repair processes is the adjustment of the latch lock. Rubbing the "tongue" against the end plate on the box is a common defect. There are many reasons for this kind of problem. The most common:

A slight violation of the shape of the canvas or opening;
Slight sagging of the sash.

To eliminate such a problem, sometimes a few light blows with a hammer on the end in the window of the plate from the rubbed side are enough. A more decisive and time-consuming way is to remove the plate and increase the dimensions of the recess in the frame, seal the old mounting holes and install the plate again.

Incorrectly or poorly delivered box, shrinkage of the building, which led to a direct deformation of the shape of the doorway, require the dismantling of the old structure and its new installation.

Dismantling the door product, photo

Important! If the dismantling process is carried out as accurately as possible, then all the elements of the box can be put back on.

The removed platbands reveal the mounting seam, and the hinges and the end plate on the box, on the contrary, “hide” the mounting points.

After the mounting seam is released, the fasteners are unscrewed and the box is removed. If the frame is fixed with foam, then the dismantling process is greatly simplified.

Sometimes it happens that the mounting bolts cannot be unscrewed. In this case, they are cut off, and the box is slightly shifted so that the new attachment points do not come into contact with the old ones.

The door frame is reinstalled, observing all the requirements regarding the levels in the vertical and horizontal planes and the size of the gaps between the leaf and the frame.

Installing and fixing the box

Important! Be sure to keep a gap between the floor covering and the canvas for supply and exhaust ventilation.

The final step is hanging the canvas and checking the functionality of the structure, fixing the end plate of the locking device and the platbands.

Door frame repair when fasteners are loose

If there has been a weakening of the wood screws that hold the frame, you can simply move them. Sometimes this method does not work, because the screws do not hold well in the loose holes.

In this case, it is advisable to replace the fasteners. Still old holes can be equipped with plugs and self-tapping screws can be mounted in them.

If the door frame was fastened with nails, it is worth strengthening the structure with additional self-tapping screws.

If the door frame is fixed in masonry, then holes are drilled in the slopes, and dowels are used for fastening.

In case of loose closing and vibration of the door in the frame, repair work consists in rearranging the locking device. For this purpose, the fixing screws are unscrewed and the mechanism is carefully removed. To move the latch of the locking device, you need to expand its socket. This is done with a chisel, the old mounting holes are closed, and the device itself is installed in a new place.

If the sash swings open and closes with difficulty, the canvas rubs against the threshold, which means that the fastening loops have loosened. To correct the situation, tighten all the screws so that the loops stop walking.

Important! If the drawdown recurs over time, the screws will need to be replaced.

door frame trims

if the platbands are worn out, have acquired an unpresentable appearance, in some places they move away from the jamb, this indicates the need to replace them.

New platbands are purchased taking into account the immediate dimensions and type of connection.

The platbands are removed, and the surface of the frame is sanded. When removing the casing, a gap may form between the wall and the frame. During the repair, this gap is foamed.

Platband replacement algorithm:

Perform markup. The part is applied horizontally so that the upper edge recedes from the outer border of the vertical casing by approximately 5 mm, and the edge on the inside from the edge of the frame by 5 mm. If necessary, the structure is leveled;
Holding the part, put a mark 5 mm away horizontally from the inner edge of the frame. Similar manipulations are performed with another casing;
Relative to the applied marking, the blanks are cut at an angle of 45 degrees. Then fix them on the box;
A vertical platband is also made and attached;

Important! The corners of the new design are also fixed with self-tapping screws.

The installation of the door and its adjustment should be carried out as accurately as possible so as not to deform the panel or the box.

Experts recommend that if there are wooden interior doors, preventive maintenance should be done, although once a year, and then the door product will last for a long time. If there are doubts about your own adjustment and repair, then it is better to entrust all manipulations to specialists.

Sometimes interior doors fail or lose their original appearance. In some cases, it is much easier to change them than to repair them, since repairs can result in a massive waste of money. Replacing interior wooden doors is not always advisable, especially in cases where the old doors were quite expensive and were of good quality.

To make a decision, it is necessary to weigh all the pros and cons in favor of replacing or repairing doors based on many criteria, it is necessary to take into account both the amount of money available and the complexity of the restoration work. Our article will tell you how to repair doors in case of some breakage, or loss in a "tradeable" appearance. Consider the main repair methods and ways to eliminate shortcomings.

Canvas repair

A common problem is that the canvas does not close properly, it touches the box. This may be due to the fact that the wood from which the door is made has swollen and expanded in size. The reason is the increased humidity in the room, or the banal old age of the canvas. As a result - the deformation of the box with the inability to close the door.

Repair with such a breakdown is quite simple. First of all, it is necessary to understand which part of the door frame is deformed. To do this, examine the gaps between the door frame and the canvas. If the gap is significant - it's in the rack, which is located on the opposite side of the gap. Another possible cause of the malfunction is canopies fixed with self-tapping screws. In order to bring them to their original state, it is necessary to twist them deeper.

In order to eliminate the above problem, two main methods have been devised.

The first of these is suitable for cases where the canvas rubs against the rack of the box. In the case when the door still closes, but with some effort, repair work can be done independently. To do this, it is necessary to deepen the landing of canopies. The canvas is removed from the hinges, which are unscrewed from the box. Then, using a chisel, the attachment points are deepened by several millimeters. After the canopies and the door are installed in place. As a rule, this procedure allows you to completely eliminate all problems.

The second way is to deliberately deform the rack of the box. To do this, it is necessary to remove the platbands, free the cavities from filling. Next, the door closes, the place where the canvas touches the box is determined. Using a drill, a hole is drilled from the inside of the box. Using a perforator, another hole is drilled through the previously drilled hole from the end of the opening.

A block of wood is taken, installed between the racks and the box is wedged, and a self-tapping screw is inserted into the hole. After removing the spacer, during normal operation of the door, everything returns to its place, and the gaps foam.

There is a third option in order to solve the problem of rubbing the canvas, but it is not recommended to use it. It consists in reducing the size of the door leaf by trimming it. It is better to cut from the side of the hinges, however, the appearance of the product may be permanently damaged.

Restoration of appearance

Restoring doors to their original appearance is a laborious process that requires quite serious efforts. In order to restore the appearance of the door structure, you must first dismantle the canvas. If a small, cosmetic repair is required, you can do without removing the canvas and eliminate the flaws on the fixed door.

So, if the damage is minor (there are small scratches, chips, and other defects in the coating), grinding the door is necessary. First of all, the surface is puttied, and only then it is polished. The damaged area is cleaned of dirt, the top layer is removed from it. Then putty is used, the excess of which, after drying, is removed from the surface of the canvas with sandpaper.

If the damage is serious, it is impossible to restore the door without removing the canvas from the hinges. The recovery process is quite complicated and requires a lot of effort. First of all, you need to remove the old paintwork of the door. It can be removed both mechanically and chemically. Preferably mechanical.

In this case, special nozzles are put on the drill, with which you can grind the surface. The chemical method is not safe. The beauty of the mechanical method is that, simultaneously with grinding the surface, it restores its original appearance. At the end of grinding, a new decorative coating is applied to the door.

Veneer and laminate door repair

Damage to the canvas can be of a different nature, depending on what the door is made of. If the doors are made of veneer or laminate, the top layer may come off or be scratched. In this case, no putty will help. These types of doors have their own ways of restoration.

If the top decorative layer of the surface peels off, this is not a very terrible problem. You can simply glue it back using superglue, or in another way: a sheet of paper is used, through which the damaged element is ironed with an iron, and then the paper is pressed against the surface of the door with a rag.

Chips, as well as scratches or cracks, can also be repaired. To do this, you should purchase a special pencil to remove damage. It is made from wax and comes in a variety of colors. It must be kneaded to a homogeneous consistency, and then applied to the canvas with a spatula. After it hardens, it needs to be polished using felt.

Fixing cracks in wood surfaces

Restoration is quite complex and painstaking. However, the result of removing cracks from interior wooden doors exceeds expectations.
Let's analyze the process step by step:

Removing the canvas from the hinges, with its subsequent location on a flat surface in a horizontal position;
Removal of the outer coating, which is done using a solvent and sandpaper;
Grinding the surface with sandpaper or a grinder;
If there are large gaps on the canvas, they are removed with a putty, selected according to the color of the surface;
After the surface has dried, it is necessary to re-sand the canvas;
Once the sanding process is completed, the surface must be primed and varnished.

Glass replacement

The presence of a glass insert is a definite plus for the door. These doors look beautiful and interesting. Unfortunately, not all types of glass are sufficiently reliable; some of them may break under mechanical stress. If this situation occurs, it is quite possible to replace the glass with your own hands.

To do this, remove the glass element from the canvas. To do this, loosen the fasteners that hold the glass insert. As a rule, fasteners are made of wood. After that, you need to wrap your hands with a rag so as not to damage them, and remove the remaining pieces of glass.

On some door structures, an additional rubber protective insert is installed, which must be removed. If it is not damaged, you can use it in the future.

In case the glass is rectangular, you just need to order glass of the same size from a specialized workshop. Figured glass can also be ordered, however, it will require a redrawing of the picture, made with unsurpassed accuracy.

Before inserting new glass, it is better to remove the canvas. This will protect against the likelihood of damage to the new glass in case of accidental damage. In addition, working on weight is not very easy.

Silicone glue is applied to the glass, and then a rubber gasket is inserted, after which the structure is fastened with a glazing bead.

Sliding door repair

Sliding doors are becoming more and more common in modern homes. As a rule, they are installed in order to save space. Various elements of fittings can easily fail and need to be replaced from time to time.

The main breakdowns include heavy opening of doors, jumping out of the rollers from the guides, as well as loose fasteners.

If it's the rollers, you can try cleaning or replacing them. To do this, the door is removed from the guides, and the rollers are cleaned and lubricated, or replaced, and then the canvas is installed in place. If the fasteners stagger, it is necessary to fix its elements more tightly.

If repair is not possible

In the event that the repair of the door is impossible for a number of reasons, it is necessary to replace it. This is much easier than repairing certain structural elements of the door. In order to change the door, it is necessary to remove the canvas, dismantle the box with a crowbar. After that, the installation site is cleared of various debris and the opening is measured.

As you purchase a new door, you will need to install fittings on it, and then proceed to install the box.

The box is installed using a level, and after installation, the remaining hollow spaces between the wall are foamed. The platbands are fixed only after the mounting foam has dried. Next, the canvas is hung on the loops.

So, if the door needs repair, in most cases the procedure can be successfully performed on your own. How to do this, you need to decide depending on the type of breakdown that has occurred. If decorative repairs are required, it is possible to update interior wooden or any other doors using the methods described above. In case of hardware failure, it can be easily replaced with a similar one, and in some cases it can be repaired. The main thing is to approach the issue wisely and then the result will not disappoint.

You can repair the interior door with your own hands. The biggest difficulty that can lie in wait for a home master is the dismantling of the door leaf and correcting the geometry of the box. Other types of work are cosmetic in nature, do not require professional skills and tools.

Types of malfunctions and defects

All types of malfunctions or defects in interior doors can be divided into two large classes: damaged appearance and improper functioning.

In the first case, restoration (restoration) of the decorative coating will be required. The methods of such repair have the same technology as for cabinet wooden furniture.

In the second case, the nature of the faults may have a different manifestation:

the door sagged and “clings” the flooring;
uneven gap around the perimeter of the porch (on the one hand, a gap, on the other - the door leaf rubs against the frame);
the door is not fixed in the half-open position (it closes or opens by itself);
latch does not work well, etc.

The reasons for malfunctioning can be subjective or objective:

installation errors;
low-quality or weak hinges for a heavy door leaf;
wear of the hinges or weakening of their fasteners;
poor fixation of the door frame in the opening;
building shrinkage.

If the hinges are “guilty”, then repairs are easy to carry out. It is much more difficult to correct installation errors or eliminate the effects of shrinkage - in most cases, you will have to dismantle and reinstall not only the canvas, but also the door frame.

How to remove and repair a door leaf

Small scratches in the paintwork of a wooden or veneered door can be eliminated without removing the canvas. It is enough to choose a shade of paint to match (for example, for artwork) and make local staining along the trace of a scratch. From above, this area is varnished (if the door is varnished) and polished.

To eliminate serious and extensive defects in the decorative coating of the door leaf, it must be removed. Do this by unscrewing the screws securing the hinges to the door frame.

Advice! Dismantling is more convenient if you first remove the trim, because usually their decorative coating also suffers. And the restoration of the canvas and platbands, so that they do not differ in color, must be carried out simultaneously.

Then the door is placed on a table (or workbench) and the following procedures are performed:

degrease the surface (oil stains have a bad effect on the adhesion of repair compounds and web material);
clean the entire surface with sandpaper with grain P60-P80 (“matte”);
putty deep scratches, cracks and chips (it is better when the putty is tinted);
dry;
grind (start with sandpaper P100-P120, finish with P200-P240);
dedust;
primed;
apply a finishing layer (lacquer, one-stage wood paint or “base” + varnish).

Repair and replacement of hinges

The simplest reason for door sagging is fastening with short screws or large diameter holes for them drilled in the door leaf and frame. In this case, it is necessary to replace the screws with longer ones (if the thickness of the box and wall material allows) or thicker ones (if the diameter of the holes in the hinge allows). In the second case, you can insert chopsticks into the holes by dipping them in PVA glue.

It may also turn out that two hinges are not enough to withstand the load from a heavy door. This is usually noticeable by the state of the upper attachment points - it is in this place that the weight of the door leaf “works to tear”. The elimination method is simple - an additional loop is cut in at the top (by the way, this installation method is typical for most modern doors made of solid wood or laminated MDF).

Weak or broken hinges must be replaced with new ones.

Repair and replacement of platbands

Repair of the decorative coating of the platbands follows the same rules as the door leaf.

The most difficult stage is to remove the platbands without damaging them. Modern products made of solid wood, veneered wood and laminated MDF are mounted on screws (and mask the attachment points) or on a finishing furniture nail (which has practically no hat). It is not difficult to remove them - you need to find and unscrew the screws or, slightly squeezing the casing from the box (through the slot from the side of the wall), pull out the nails with pliers.

The trim of old doors (with several layers of paint) is almost impossible to remove without damage. But if this succeeds, then we must take into account that their cleaning and grinding will take a lot of time. Better to replace them with new ones.

How to repair a door frame

Cosmetic repairs of the door frame are carried out "in place". To putty and mask scratches in a small area of the visible part of the box, you should not remove it.

One of the simplest types of repairs can be called the adjustment of the latch lock. A common defect is the rubbing of the "tongue" of the lock on the end plate on the box. This can be even with minor and imperceptible violations of the geometry (cloth or opening), slight sagging of the door, after repair or replacement of the hinges. Sometimes a few light blows with a hammer on the end in the window of the record from the “rubbing” side are enough. A more radical method is to remove the plate, increase (if necessary) the dimensions of the recess in the box, close up the old mounting holes, and install the plate again.

An incorrectly or poorly installed frame, as well as shrinkage of the house, which led to deformation of the geometry of the doorway, will require dismantling and reinstalling the door. If dismantling work is carried out carefully and accurately, then all elements of the interior door (frame, canvas, trim) can be reinstalled.

Note! The removed platbands open the mounting seam, and the hinges and the end plate on the box "hide" the places of its fastening with anchor bolts or self-tapping screws in the opening.

After the mounting seam is cleaned, unscrew the fasteners and remove the box.

If the box is fixed in the opening only with mounting foam, then dismantling is easier.

But it also happens that the anchor bolts cannot be unscrewed. You will have to cut them off with a grinder, and shift the box a little so that the new attachment points do not fall on the old ones.

Then the door frame is reinstalled, observing the requirements for levels in the vertical and horizontal planes, the size of the gaps between the leaf and the frame. At the bottom it is necessary to leave a gap between the door leaf and the floor covering (or threshold), sufficient for natural supply and exhaust ventilation.
