Peeling plaster is a common problem that can occur in older homes or due to moisture issues. Here are some steps to repair peeling plaster:
1. Remove loose plaster: Use a putty knife or scraper to gently remove any loose or peeling plaster. Be careful not to damage the underlying wall.
2. Clean the area: Use a damp cloth or sponge to clean the surface and remove any dust or debris.
3. Apply a bonding agent: Apply a bonding agent or primer to the area to ensure proper adhesion of the new plaster.
4. Patch the area: Mix plaster according to the manufacturer’s instructions and apply it to the damaged area using a trowel or putty knife. Smooth the surface and let it dry.
5. Sand and finish: Once the patch is dry, sand it down to create a smooth surface. You can then paint or wallpaper over the repaired area to match the rest of the wall.
Remember to take necessary safety precautions and consult a professional if you’re unsure about the repair process.
Dealing with peeling plaster on a wall may seem overwhelming, but it’s actually a straightforward process once you know the right steps. Before you start, it’s important to understand why the plaster is peeling or bubbling in the first place. If water is the cause, it’s best to seek professional help to address the issue before attempting any repairs. Water can cause significant damage and cannot simply be covered up.
Step 1
Begin by preparing the surface. Scrape off any old paint or bubbling texture using a putty knife or wide blade scraper. Wipe away any residue with a damp sponge.
If the surface is mildewed, it must be treated with a mildew remover. Spray the remover on and leave it on the surface. Reapply if necessary. Rinse the surface well. Once it’s dry, scrape off any loose particles. You may also consider applying a layer of mildew killer, such as a plaster sealer or KILZ.
Step 2
If there are deep holes, pits, or cracks, plan on filling them. Mix a joint compound, such as a fast-dry setting type or Sheetrock® Easy Sand™. For long cracks, you may need to slightly widen them before filling them in with a joint compound specifically made for walls. If the cracks are too large, apply drywall paper tape to reinforce them.
Step 3
Apply the joint compound in thin coats, known as “skim coats,” until the flaws are covered. Use a modified arc sweeping motion with the towel angled at about 15 degrees to the wall. Smear the edges to create a taper. If desired, use a damp sponge to smooth out any ridges. Allow the compound to dry completely. Sand between coats.
Step 4
Apply a final coat with a texture that matches the previous surface. If you’re working on a large wall with an all-over application, feel free to experiment with different techniques.
Step 5
If desired, paint the repaired area. However, wait several days to a week for the plaster to fully dry before applying paint.
