Repairing large holes in drywall
Simply gluing the patch is NOT suitable for large holes. there is a high probability of the glued fragment falling out. Therefore, before repairing a hole in drywall on a wall measuring 10 cm or more, you will have to stock up on tools and materials:
- Screwdriver and / or drill;
- Self-tapping screws;
- Wooden block or Fence;
- A piece of drywall of the appropriate size;
- Serpyanka;
- Primer, putty, putty knife.
First, a quadrangular fragment from the GCR is cut out, slightly larger than the hole. Applied the resulting patch to the damaged surface, mark the edges of the future hole. Then carefully cut the drywall along the outlined fishing line. In order to prevent the seam from cracking in the future, the edges of the liner and the holes are cleaned with a knife at an angle of 45 ° so that a groove is formed with a triangular section.
Next comes the turn of the frame for the patch: a wooden block (Picket) is cut 5. 6 cm longer than the hole and pushed inside. Presses it to the seamy side of the drywall, screw the wooden frame with self-tapping screws from the front side. The number of bars depends on the size of the hole. they should be enough for a fixed position of the liner.
After fixing the patch, the surface is primed. The joint seam is sealed with a serpyanka and filled with a base putty. After drying, apply a finishing putty and sand.

Renovation of a modern apartment is rarely complete without drywall. The alignment of walls, the device of partitions or the formation of design delights in the form of arches, curly niches, columns is NOT complete without this versatile material.

- After the glue dries, the sealed hole is putty.
Further actions depend on the type of decorative wall covering: painting requires careful alignment, since the slightest flaw is noticeable on the painted surface. Therefore, you may need another layer of putty and a thorough smoothing with fine-grained sandpaper.
Damage sealing 3. 6 cm
Repair of holes in drywall with a size of 3 to 6 cm or more is done using patches made from the same material. This is why you shouldn’t throw away drywall trim after renovation. a few pieces should be left just in case. Otherwise, you will have to ask around from familiar builders who work with GCR.
The easiest way is to cut a round hole in the damaged area using a drill with a drywall attachment (crown). The hole is made with smooth edges.
Then they start making the patch with the “crown”:
- Cut out a square with sides 4. 5 cm larger than the diameter;
- A circle is drilled from the seamy side, do not reach the front paper layer;
- With a knife, chisel or any tool at hand, they clean the plaster. The result should be a round insert with a square front part of paper;
- The patch and the surface of the drywall are primed, and not excluding the filling of the hole and the ribs of the liner;

There are several ways to solve this problem:
- Using a hammer drill or a powerful impact drill;
- An ordinary electric drill or screwdriver;
- Diamond drilling.
It should be remembered that for walls made of relatively soft materials, it is impossible to use victory drills, since the holes will turn out to be uneven, and the wall will collapse. It is also impossible to work with metal with such a tool.
To create large-diameter holes or cut a doorway, diamond-coated core drills are used. To use such a tool, it is necessary to use special installations, they allow you to make holes with a diameter of up to 250 mm.
Since the cost of such equipment is high, it is easier to hire specialists or you can rent it.

For the base, furniture (faced) chipboard with dimensions of 300 × 250 mm and a thickness of thirty mm was used. For the table (working plate), a hard duralumin plastane with a thickness of four mm is selected [.]
Drill
The tool is suitable when you need to make multiple holes. You can use a conventional drill. When immersing a victorious drill into the body of the wall, sometimes it is necessary to break concrete. A punch, which coincides in diameter with the hole. This is necessary when the drill starts to get stuck in the surface bumping into too dense areas. The process is quite laborious.
For greater efficiency, you can use universal drills, which have a diamond coating. They are installed only on a conventional drill or on a tool where the vibration function is disabled.
For large-scale work, an impact drill and drills with victorious tips are used. They are designed for holes up to 12 mm. The drill is suitable for working with metal, concrete.
How to properly drill a reinforced concrete impact drill for a pipe
