What you’ll need

  • Damp cloth
  • Sharp knife
  • Latex gloves
  • Sealant
  • Wall paint
  • A repair kit which includes a putty knife, sandpaper
  1. Repair

The best way to repair door handle holes and many others up to 13 centimeters (five inches) in diameter is to use a repair kit available at a local hardware store or DIY store. A typical kit contains a filler and a glue fitting made of fine and perforated metal or mesh fiberglass.

Some kits even provide sandpaper and a putty knife. The kits are available in different sizes. Choose the one you need.

Brush or cut off the loose paper and remove the crumbling plaster. Wipe the surface with a damp cloth to remove dust or dirt. Let the wall dry.

Size the repair if necessary. Mesh metal fittings can be cut with scissors. Remove the repair bracket, center it, and glue it to the wall. Press the edges to stick them well.

Apply the coating to the repair with a drywall knife, flattening well beyond the edges. Once the plaster is dry, sand and apply a second coat.

Finally, apply a third coat for a smooth, sufficiently large repair with slightly sloping, less visible edges.

  1. Let it settle down

You don’t want to repair a crack and, two months later, it is back, do you? The problem is usually due to subsidence, which is a common problem in new homes, especially at the corner of windows and doors. It is advisable to plug the small cracks that reappear with mastic paint which is more flexible than the filler.

Another tip: Put on a latex glove and wipe the caulk gently with your finger. For larger cracks, use soft sealant and apply with a putty knife.

The final step in any wall repair is to sand the repaired area and then smooth it before painting. But sanding, even if it is only a small repair, creates large amounts of fine white dust that will be dragged throughout the house. To avoid getting dirty, wipe the component with a damp sponge. It will allow you to smooth the surface as well as sandpaper it while leaving you less cleaning to do.

  1. Repair the blisters

If a blister forms on the joint, the person who laid the wall probably did not put enough joint compound on the joint. To solve the problem, simply cut the blistered area with a sharp knife, then use plaster to repair the damage and then smoothen and retouch the painting.

  1. Corner problems

Drywall corners projecting outward may be prone to get damaged when hit probably by a laundry basket, child’s toy or furniture. Fortunately, the repair is easy.

The outer corners are protected by a metal piece, called a corner wand. It is molded on the corner, nailed to the plasterboard and then covered with a joint compound. If a corner wand is bent, give it its shape by gently tapping with a hammer and file the sharp edges to make them smooth.

As the existing corner strip provides support for any repairs made, you have the option, in this case, to plug with a quick-setting sealant or putty compound. Fill in the damaged area and smooth with a putty knife.

Once the repair has dried, sand or smooth with a sponge, before applying a coat of primer and then paint.
