In detail: DIY repair of a wooden window frame from a real master for the site my.housecope.com.
Many modern people strive to make their home as environmentally friendly as possible and are in no hurry to replace their usual wooden windows with new plastic. And this is not surprising, because wood is considered a valuable natural material with a lot of advantages. One of its main advantages is the possibility of repair. The restoration of wooden windows is not an easy task, but it can be solved. It makes it possible to give the old structure the appearance of a completely new product.
Do-it-yourself wooden window restoration allows you to save your budget and improve the dilapidated window structure. Before starting the repair, it is necessary to take into account the "life" of the material from which the frames are made. Larch and pine can last no more than 35 years, oak and beech - more than half a century.
Restoration of wooden windows is unlikely to lead to the desired result if:
The structure of the wood is so loose that when pressed, strong dents are formed;
There is a complete loosening of the window frames in the openings;
Large dark spots are visible under the paint, which are usually indicative of dust and decay;
Frames are bent or strongly deformed;
Wooden windows are severely damaged (for example, cracked frames).
After reconstruction, the old window looks like a new one
The restoration of old wooden windows is usually carried out according to the "Swedish" system, which allows combining the repair and thermal insulation of the window structure... To work, you will need a certain list of tools:
Selector (zenzubel) - a plane for the formation and cleaning of grooves, folds and claws;
Several chisels 4-30 mm wide;
Saw blade 0.3 mm thick and 4-6 mm wide;
Palette knife or flat knife (boot);
Carpenter's Square;
Core drill for wood (8-10 mm ID);
Level and plumb line.

For a high-quality restoration of the structure, you need to stock up on special tools
About 300 grams of "liquid nails";
Drying oil;
0.5 kg of wood putty or 0.5 kg of fine sawdust;
Zinc or titanium thick-grated white;
Kerosene;
Brushes;
Carnations (500 gr. Small and 60-80 mm);
Sandpaper;
Plywood or board board slightly larger than the window frame;
Plastic bag 0.5 m wide, 1.7 m deep;
Pieces of water-repellent plywood with a section of 1-1.5 mm;
Silicone based aquarium glue - 10-20 ml.
A plastic bag and kerosene will not come in handy if you use a factory hair dryer. It is not recommended to use deep-penetrating polymer putties on wood on water, as they will significantly increase the thermal conductivity of wood parts.
It is better to start repairing wooden windows with your own hands in warm, not damp weather. Recommended humidity - 40-65%... In the event of bad weather, window openings must be temporarily tightened with waterproof material.
The repair of wooden windows begins with an inspection and check of a double-glazed window. It is necessary to remove the sash, remove the glazing beads or remove the putty, remove the glass.
Repair begins with inspecting the surface of the frame and removing the old putty.
Dismantle the fittings (a new one will be installed in its place). Carefully remove the external wooden sills, remove all fasteners and iron squares.
Window restoration should only be started after thorough drying of all wooden parts..
There are several methods to remove paint from old-style windows.
Removal of the coating must be done carefully and carefully. It is recommended to remove the glasses in advance, as they may crack if hot air is directed.
The recommended temperature of the hair dryer is 250 0C. With increased values, the wood will char and lose its characteristics. When heated, the paint will begin to bubble and can be easily removed with a professional knife or palette knife.
The most effective method of removing paint is considered to be the use of a building hair dryer.
Old wooden windows will not withstand the aggressive effects of solvents or solvent, therefore, only kerosene should be used to remove paint:
Wrap the wooden frame with fabric material and lower it into a plastic container;
Thoroughly moisten the cloth with kerosene, close the container and leave for a couple of days;
Remove the strips one by one and remove the paint. If all the parts are pulled out at the same time, then the kerosene will evaporate, the paint will harden again and stop flaking;
Remove any remaining paintwork with an emery cloth or grinder.
It is recommended to use kerosene as a chemical solvent.
The decayed section of the frame can be replaced or restored. An epoxy wood filler is required for the restoration. The damaged area must be freed from paint and debris removed. Then apply the putty, carefully filling all gaps and cracks. Form the missing part. It should be slightly larger than the required size, since the excess will be removed during subsequent grinding.
If the decayed area cannot be replaced, the defect is eliminated with a putty
Leave the frame to dry for at least a day. Sand the repaired area with sandpaper or a grinder.
It should be understood that such a repair of old wooden windows helps to restore the appearance, but does not provide the necessary reliability, especially in areas of active use. But on a blind or rarely used window, this method will allow you to restore the structure without a cardinal replacement.
Before carrying out this operation, it is necessary to identify cracks, chips and other defects in wooden windows, mark them with a marker and process with sandpaper. Then cover the marked areas with latex or oil putty. The work is carried out with a rubber spatula, immediately removing excess material. If necessary, after the first layer has dried, apply the second one. At the end, the wooden surface is treated with fine-grained sandpaper. The primer is applied in 2 layers.
In order for the repaired old and Soviet windows to serve as long as possible, they need to be coated with linseed oil... It will block the development of new embryos of rot and, if possible, restore the structure of the old wood.
Coating with linseed oil will extend the life of the window frame and prevent the formation of rot
The drying oil is applied with a brush in 3-4 layers: the next one - after the absolute absorption and drying of the previous one... Such processing will last for 2-3 years (until the next repair). Impregnation for many decades has been carried out in a piece of iron pipe 10-12 cm thick, sealed at one end. All actions must be performed only on the street, away from residential buildings.
Install the pipe at an angle of 300, fill ¾ with linseed oil and heat from below with hot air from a hair dryer or electric stove. As the temperature rises, the drying oil will begin to swell - this will release moisture and air. If there is a sharp increase in the smell, you need to move the heater aside and wait a little. Impregnation begins after the bubbles disappear:
Prepare an iron hook with a sharp end, 5-6 mm thick;
Place the part in the pipe and press it down with a crochet hook for 4-5 minutes;
Hook the bar with the tip of the hook, remove and lay to dry;
It is forbidden to touch the parts with your hands (even with gloves), since the temperature of the hot drying oil exceeds 130 degrees.
Such processing allows to extend the service life of wooden window frames by more than 100 years, and if they are coated with an oil composition, then repainting will be required no earlier than 15 years later.
The prepared sashes are laid on the board and carefully aligned to squareness. Particular attention should be paid to the details of the vents: a 1 mm difference in the diagonals will provide a 0.7 mm gap.
The leveled area is fixed with glue or nails, carefully driving them into the shield near the sash. They are looking through the old pins ("chopiks").
When assembling the sashes, it is necessary to strictly observe the rectangularity
Drill them in the middle of the corner using a larger diameter drill. If any of the pins is shifted to one side, then you need to:
Fasten it along the border with a few drops of "Super Glue";
Drill the correct location;
Stretch the saw band through the slots between the fixing bars and saw through the old nail.
After assembling all the corners, you should get a fairly rigid structure. Now you can take the frame and install the sashes into it. They will sit more tightly if plywood strips of the appropriate width and thickness are glued to the frame.
Place all parts on a leveled canvas and press down with a load (approx. 100 kg). Leave to dry and level for 2-3 days.
High-quality repair of wooden double-glazed windows includes their insulation, which can significantly reduce heat loss at home. You can insulate windows with your own hands in several ways:
Silicone sealants;
Special paper;
Cloth stripes;
Tubular profiles;
Heat-saving film;
Seal in the frame sashes.
The last two methods are considered the most effective. First, the joints of the sash and glass are covered with silicone sealant. Then they take a milling cutter and cut a 5 mm depression along the perimeter of the sash at an angle of 450. They clean it from shavings. The PVC sealant is sequentially pressed but not stretched into the resulting groove.
When restoring the structure, a mandatory step is to insulate the window frame
Most often, the repair and restoration of wooden windows ends with painting. For this, it is recommended to use special compounds that are well resistant to temperature extremes and the effects of precipitation: oil paints, acrylic and alkyd enamels.
The coating must be applied in 2-3 layers
It is advisable to cover the windows with two or three layers of paint, spreading it as it ends... Optimal consistency will create an even, non-flowing layer. Initially, it is best to work with a thinner paint. You should not try to immediately close all the visible flaws on wooden windows, since the bulk of the initial layer will still be absorbed. The second layer is applied only after the first one has completely dried.
It is advisable to paint the window frame with the glasses removed. This will allow you to skip the unpleasant smudge removal procedure.... But if the glasses have not been pulled out, then to protect them, you can use a special masking tape glued back to the frame.
The restoration of wooden double-glazed windows ends with the installation of glass. The procedure consists of several stages:
Squeeze out some silicone aquarium glue under the inner corners of the frame;
Insert glass and secure with studs;
Remove glue drips with a cloth soaked in vinegar;
Do not completely scrape off the silicone from the fasteners: it will protect them from rust;
After the glue has set, fix the glass with putty (chalk + drying oil) or pre-treated glazing beads.
It is necessary to properly fix the glass in the window frame
