Repair the plasterboard 2nd part - Important damage

Evaluation of damage

Important: if the hole is large, we will need a reinforced network with a metal core suitable for this type of situations and metal uprights (or alternatively wooden slats) to be positioned possibly inside the hole. Proceed then placing a piece of new drywall cut to size to "cover" the damaged area and obviously we will stucco to finish everything.

Repair in 8 moves

• place a 4x4 covering cloth on the ground to protect the floor from dust and debris.

• cut a piece of plasterboard just bigger than the damaged area, place it on the wall and use a construction pencil to trace the shape of the hole we are going to make.

• cut the slab section with a professional saw for plasterboard.

• cut pieces of metal section for plasterboard structures or alternatively two strips of wood about 6 cm wide and fix them inside the hole created with 3.5x25 phosphated self-drilling screws, leaving a visible part.

• Insert the previously created piece of plasterboard into the hole and screw it onto the visible part of the pieces of metal section for plasterboard structures or the two strips of wood.

Note: if the piece of plasterboard does not enter the hole in a fluid way, proceed to file the parts in question using a plasterboard saw or a professional planter.

• Now place the joint cover tape on the joints and fill all the part concerned with a professional spatula.

Note: allow the grout to dry and repeat the operation until a perfect shave is obtained.

• sand the area with a manual grinder to make the surface uniform and smooth.

• whiten with special paint for plasterboard and an interior roller
