How to fix a hole in a concrete, brick and plasterboard wall

Walls of premises, whether they are brick, plasterboard or concrete, often receive damage of a variety of character. Because of this, they often form holes. Understand how to repair a hole even if it has no experience in construction work. Holes are easy to cover, but in order to do it qualitatively, one must understand that the nature of the work depends on the material from which the wall is built.

Blanking holes in the wall

Fixing holes in brick or concrete walls, like any other case, begins with preparation. The first thing to do is estimate the size of the hole.

To seal small holes need:

• Vacuum cleaner;
• Small trowel;
• Combination pliers;Dowel-nail.

The hole is cleaned from the inside with a dowel-nail, squeezed into the pliers. Then all small building debris is removed by a vacuum cleaner. The cleaned hole is covered with a putty. The trowel movements should be simultaneously indenting and leveling.

Remember that from how well the hole is cleaned, the aesthetic qualities of the wall will hang.

If the hole is large, then first you need to decide what to wall up the wall. Good for alabaster, plaster or cement mortar.

These tools will be needed:

• Spatula, large and small;
• Alabaster, plaster or mortar - to choose from;
• Sandpaper;
• Sponge.

. As with small holes, first clean the surface of the crumbled plaster. Then it is necessary to moisten the cleared area and wait until it dries. After that, you can plaster the hole and the area around it. When the material is hardened, sand it with sandpaper.

Closing a hole in a gypsum plasterboard wall

Questions about how to seal a hole in a plasterboard are more common, since this material is less durable than brick or concrete. In this case, it is not easy to cover the wall, but to repair the damaged part of the wall. You will need:

• Pencil and ruler;
• Spatula;
• Screwdriver;
• Hacksaw;
• Self-tapping screws;
• Sandpaper;
• Putty;Drywall and wooden board.

With a hacksaw, the hole is given a rectangular shape. To do this, the contours are first applied with a pencil. Now you need a wooden board or profile.

It is necessary to pick up the board so that its width is slightly less than the diagonal of the hole, and the length exceeds the opening width by 6-12 cm.

The board is placed on the back of the wall. In order to fix it, you need to screw the screw into the center of the board first, it will serve as a "handle" for fixing. After fixing the board, the "handle" can be removed.

After screwing in the screws that hold the board, they must be "inverted" into the drywall. Otherwise they will interfere and look ugly.

Next, a plate made of plasterboard is cut out corresponding to the size and shape of the hole, it is screwed with screws to the board, and the fiberglass tape is glued on top. After that, apply the main and finishing layer of putty. When the glue dries, the surface is rubbed with sandpaper.

Those who did not work with gypsum plasterboard before, have difficulty in cutting it. How to get a smooth piece? To begin with, you need to apply a contour, along which the cutting will be performed, on both sides of the sheet. Next, you should make deep cuts along the lines. Then holding the main part of the hand, it is necessary to break the sheet, it does not require any special efforts.

Before closing the hole in the gypsum board, you should estimate the hole dimensions. If it is too big, then you should not bother with fixing the patch. In this case, it is better to resort to a complete replacement of the sheet.

Embedding other types of holes

Some practical tips for sealing holes on the ceiling and walls, depending on their type.

Cracks in the joint of the floor with the

wall. They are closed in the same way as the holes in the walls, with one feature - before the sweep the gap must be widened by 5-10 mm along the entire length. This will give more reliable adhesion for new plasters.

Holes in the ceiling after plastering

The easiest way is simply to cover with a new layer of plaster, but this decision will not be correct, since soon a hole will appear again, because it is not easy to remove the "symptom" and completely cure the "diseased organism".The procedure is as follows:

• Before closing the hole in the ceiling, it is necessary to carefully clean the damaged surface. It is important to do it qualitatively;
• Treat the surface with an antifungal agent, because it is the fungus that is most often responsible for the staining of the plaster;
• Bypass the hole and the area around it by a primer;
• Fill the surface in 2-3 layers, depending on the required thickness, and do not forget that each layer needs to be allowed to dry;
• Wipe the ceiling and re-prime.

Cracks at the joint of

panels The problem that often occurs in panel buildings. Sealed in the same way as the cracks between the ceiling wall, but for reliability you need to glue along the entire length of the fiberglass mesh.

Holes near risers

Often, plumbing works to replace the riser are performed in bad faith and after their execution, cracks and holes appear. Small holes up to 5 mm can be filled with silicone sealant.

With larger holes is more difficult, you need to make a simple reinforcement, then a hole in the hole. When the foam hardens to cut it 5-10 mm above the ceiling, and putty with plaster filler. If the hole is large, then the perfect Rothband is used for plastering.
