Repair is the most common occupation that accompanies a person throughout his life. And even if it was done thoroughly, then in a year something will have to be repaired. Grease, glue and even plaster. After all, it often happens that, through negligence, when moving furniture, they scratched their expensive, so carefully glued wallpaper, but that's nothing. And if they were torn, and even in the most conspicuous place. What to do? How to repair wallpaper so that its traces are not visible?
Preliminary preparation of walls
When renovating apartments, wallpapers play a major role, because they are the most contemplated element of any home. Therefore, the base should be prepared as efficiently as possible.
First of all, before starting gluing, you should inspect the place of damage. If it is deep enough, then the surface must be putty and cleaned with sandpaper. Then a piece of the wall is treated with a deep penetration primer so that the wallpaper does not fall off again in this place.
Often among the damage to the wallpaper there are tears due to cracks in the wall. This happens mainly in new homes. Moreover, both in one-storey and in multi-apartment multi-storey buildings. This process is inevitable, because any structure shrinks, in which cracks appear in the weakest points of the walls:
- joints of plates;
- thin partitions.
Before repairing damaged wallpaper, do the following:
- Remove the wallpaper with a strip of at least 20 cm wide along the entire length of the crack.
- Remove the old filler and make the crack wider so that the plaster mixture can be applied to it.
- Before plastering, it must be treated with a high penetration primer. After complete drying, plaster this piece of wall, while laying the metal mesh. When leveling the surface with a filler, it is also recommended to use a glass fiber reinforcement stack.
Types of damage on wallpaper
A wide variety of damage can occur on the wallpaper, the causes of which can be anything:
- human factor;
- poor quality glue or improper preparation of the base in some places;
- old age.
As a rule, in the latter case, the walls are completely re-glued, therefore everyone will not like redness, and against their background pieces of new wallpaper will stand out very much. Therefore, we will consider cases with physical factors. But before starting work, the first thing you need to do is choose wallpaper for repairs that match in color and texture.
Scratches are the most common causes of damage to wallpapered walls. They can be both large and small. Based on this, the scope of work is selected. Here, the geometric parameters of the wall should be taken into account, if the scratch is on a small separate section of the wall, then it can be re-glued completely, which will be the best option. If the scratch is in the middle of a large and flat wall. Then on the wallpaper they mark a rectangle, square or strip of the correct shape and cut it out carefully using a mounting knife and a level, rule or ruler. After that, a piece of the same regular geometric shape is cut out of a new piece of wallpaper, but with a margin of 1-2 cm on all four sides. The prepared piece is glued to the wall using known methods. After that, using the same assembly or wallpaper knife and a ruler, all sides of the piece are cut through with an indent of 0.5 - 1 cm from the edge. The cut edge is carefully removed and the edges of the newly glued piece are raised to remove the old wallpaper from under it. And everything is rolled into place with a wallpaper roller. If the wallpaper has a certain pattern, then, therefore, it is necessary to select it.
If the damage happened exactly on the drawing itself, then you can only replace it by cutting it carefully along its contour. With this method of repair, defects will not be visible at all.
If the scratch turned out to be small, then using a thin brush, the glue is applied to the lagging pieces. Then gently press down with a clean and dry cloth to remove excess. Be sure to keep the piece wet with glue. After that, the place can be rolled with a roller, expelling the air.
If for some reason the wallpaper turned out to be torn, then there are two options for action:
If a piece of them is still hanging, then you can simply glue the wallpaper with some liquid and white glue. For these purposes, the glue for gluing wallpaper can be known to everyone as PVA.
Be sure to let the edges soak to soften the edges and make them more pliable.
It should be remembered that heavy wallpaper requires the use of a more durable glue. And to speed up the drying process, you can use a regular hair dryer to dry your hair and set the average temperature of the air flow.
If a piece of wallpaper is missing. Then here you should act as described in the first case.
When scuffs of large sizes form on the surface of the wallpaper with the manifestation of their structure, then it is necessary to act here as described earlier. Cut a piece of the correct geometric shape on the wall and from the remains, but larger. Then glue with PVA and roll on. Next, trim off the edge and remove the remnants from under the piece just glued.
Wallpaper gluing can also be carried out in the second way when scuffing is formed. The piece to be glued does not need to be cut along a straight line and in the form of a regular geometric figure. It can be torn off while the tear should go in the opposite direction so that the edges of the wallpaper are not noticeable from the front side. This will make these edges thinner, which will provide better adhesion and blending with the background. Here, the main thing is to roll the piece well with a roller and coat it with glue.
Air or blistering wallpaper
We take an ordinary syringe, collect PVA glue and introduce a little into the cavity in different places. Then we smooth the surface.
The gluing of wallpaper joints is carried out as follows:
- Using a thin brush, gently smear the bent joints of the wallpaper.
- Then, using a roller, they are re-rolled against the wall.
- Let the canvas soak.
A radical method. If, after diligently smoothing the wallpaper, seams form at the joints, then they can be successfully masked. To do this, you need a thin brush and paint to match the color of the wallpaper. The edges of the wallpaper should be carefully torn away from the wall, if possible. Then paint the wall at the junction and let it dry.
You can also play it safe if the preparation of the wall is not good enough, at the joints, glue paper tape (the usual one for cash registers is suitable), this procedure is good to carry out at the time of pasting the walls with wallpaper.
