Tips on Drywall Repair

  

A sheet of regular drywall weighs about 1.7 pounds per square foot, which is about 54 pounds and that is how heavy this kind of material that you will be dealing with during your repair on it.

There are two kinds of pre-mixed joint compounds in repairing drywall for coating cracks, holes, etc. on a drywall - all-purpose joint compound and the lightweight joint compound. The all-purpose joint compound contains more glue agents than the lightweight compound and is used to embed or coat over paper tape on seams on a damaged drywall and used as a first coating. The lightweight joint compound, which contains less glue agents, is mainly used as a second coating, but more as a finish coating over seams and corner bead of drywall areas.

Use a peel-and-stick patch which is an aluminium screen covered by a fiberglass mesh, in repairing a doorknob hole of a drywall, and press the patch over the doorknob hole using a 4 inch or 6 inch drywall knife to apply all-purpose joint compound over the mesh and make about three coatings of the compound over the mesh.

Repairing battered corners can be fixed following these procedures: first, cut away the metal corner bead with a hacksaw; second, use a nail bar to remove the damaged section of the corner bead; third, hold the new corner bead in place by marking its length; fourth, cut a new section of the corner bead to length and nail it and sand the surface of the bead if it is glossy; fifth, coat the bead with several coatings of lightweight joint compound using an 8 inch drywall knife.

The following steps are suggested to repair soggy, drywall ceilings: use a hand sander and coarse sanding mesh to remove out texture and smooth out the damaged ceiling area; if water is the cause of the drywall ceiling to sag, re-attach the ceiling along the seam, nailing the drywall to the joist; apply a coat of stain-sealing, shellac-based primer over the damaged ceiling; use a roller to apply a mixture of drywall compound with water over the ceiling; after the drywall compound has dried up, add texture back to the ceiling using a short-handled stomping brush.
