Damaged plasterboard:DIY repair

Repair depends on the type of damage and the characteristics of the drywall. The most frequent damage is given by the classic hole caused by a sharp object. You were probably trying to hang a picture on a plasterboard wall or you were just a little clumsy. Don't worry, a hole in the drywall can be repaired.

How to fix a hole in a plasterboard wall?
First, get some super flexible duct tape. You can find it in DIY stores, in the construction - carpentry department. This tape is used to cover the cracks and holes in the walls. The tape is very dense and should be applied like simple adhesive wallpaper. The duct tape does not need filler or further finishes, in fact it is available in different colors according to your needs. To make you understand thesimplicityof this repair, just look at the type of material you need to use: white cloth tape for repair and decoration.

In case of plasterboard with special finishes

To obtain an ideal finish, you can apply a mesh tape (fiberglass type) on the hole to be covered, perform a first grouting and then continue with the finish suitable for the rest of the perforated panel.

The anilox tape has very dense meshes able to anchor the filler. It is a suitable support in case of medium sized holes because in case ofdamaged plywoodwith very large holes, in addition to the use of fiberglass it will be necessary to use wooden strips (including plywood).

To get an idea of ​​the type of material to use, I refer you to the Amazon page which offers rolls of good quality anilox tape: glass fiber 25 x 50 cm.

In case of very significant damage

If the hole is extended and also affects a large part of the wall support support, the repair work becomes a bit more complicated. In this case you can still use the anilox tape but the repair may leave something to be desired.

Extensive damage requires a preparatory phase in which you will cut away the shattered edges of the plasterboard using a cutter. Once you have a square hole (even 20 sides, you just need to have each side straight!) You will go and sand the edge of the cut.

With the aid of rigid cardboard strips, reconstruct the internal shape of the break: this shape will act as the basis for anchoring a wooden profile that will become the new support for the perforated part of the plasterboard wall. We advise you to use wood, birch plywood to be fixed with fast two-component glue (epoxy or polyurethane glue, fast weighing for wood) is fine. Exclude the use of vinavil because it is too slow in drying.
