A classic case of “stupid”: The plan was actually to install spots, but then it shouldn’t be anymore. But what if the holes have already been drilled? Fortunately, the affected wall is drywall, so repairing it isn’t a big deal. However, there are a few things to consider. We show how easily wrongly drilled holes in a plasterboard wall can be repaired so that the hole in the plasterboard wall can be repaired.
TOOLS AND MATERIALS
Repairing holes in drywall doesn’t require many tools. Every DIY enthusiast has most of them ready anyway. A drill, a circular hole saw, a precision saw, a cutter knife, a cordless screwdriver, a screwdriver as well as a construction bucket, and a few spatulas are sufficient.
The material required is a wooden lath, the remnants of a drywall sheet, a few drywall screws, filler, and some joint tape.
With drilled and circular holes, it is not necessary to use repair nets for drywall. The most straightforward repair in these cases is to replace an equally large piece of drywall. Of course, this requires the right filler pieces. These are to be made before the actual repair of the plasterboard wall.
For this purpose, a suitable counterpart is sawn out with a circular hole saw from a leftover piece of drywall. That didn’t happen spectacularly and quickly. Then the filler pieces are chamfered so that the transition remains invisible when filling.
Next, an approx. 3 x 1 cm thick wooden lath, the length of which is twice the defect diameter, must be cut to length. This is then pushed into the defect in the course of the project and screwed to the intact drywall. The filler piece can then very easily be screwed to this lath, and the hole closed in this way. Awesome.
The preparations for the repair of the plasterboard wall are already completed.
REPAIR THE HOLE IN THE PLASTERBOARD WALL
Now the hole or holes in the plasterboard can be repaired. To do this, the edges of the wrongly drilled hole are first chamfered. Then the wooden slat is placed over the defect, and its outline is transferred to the plasterboard. Two additional lines on the wood provide orientation for the alignment of the lath in the defect. Because as soon as this has been inserted into the defect, the alignment can no longer be determined without any doubt without such markings.
Then the wooden lath is screwed to the intact drywall. The drywall screws are screwed in so far that they are sunk a little bit into the plasterboard wall. In this way, the screws can be completely concealed during the subsequent filling.
Once the makeshift substructure is ready, the filler pieces can now also be added. These are inserted into the existing holes and fixed with a drywall screw. This is generally sufficient and provides the necessary support. Perfect! The hole would then already be filled. In the next step, the repair area is covered with joint tape and neatly filled.
Note: Drywall screws with a coarse thread are used for wooden substructures – in contrast to metal substructures, where screws with fine threads are used.
FILL THE REPAIRED HOLE
Of course, the filler is now also required for filling. This is prepared as follows: cold water is placed in a bucket, and the filler, preferably smooth filler, is slowly sprinkled in until it is just below the surface of the water. If the filler is too thin, a little more filler can be sprinkled. But not too much, because you will not be able to add more water!
Tip: Before the filler is mixed, it is advisable to let the mass soak for a few minutes. This ensures lump-free mixing and provides a perfect result.
Once the filler has been mixed, it is applied to the defect at a flat angle with a wide spatula. After the compound has been allowed to dry briefly, two joint tape strips are placed next to each other and the defect is covered again.
After it has completely dried out, the repair area is briefly covered over again and filled again. Then the already closed hole in the plasterboard wall can be painted with paint.
Done! The hole in the drywall was closed and neatly filled. As soon as the defect has been painted, absolutely nothing can be seen of a hole in the plasterboard wall. That’s how it should be! And almost the most beautiful: the repair was a lot easier than expected!
