How to Repair Plaster Walls

It is inevitable that any plaster wall will become damaged over time. Whether it is a hairline crack or a deep gouge, these structural damages can not only make any decor look unappealing, but also can potentially bring down the property value of the home. The good news is that you don't have to hire a contractor to repair a plaster wall. With the right tools and materials, damage can be repaired quickly and inexpensively.

Things You'll Need

• Spackling compound or mixed joint compound
• Fiberglass mesh
• Drywall knife or putty knife
• Rubber float
• Sandpaper

Instructions

1. Prepare the surface of the crack by smoothing it with sandpaper. Scrape the edge of the opening. If the damage is a hairline crack, you might have to widen it to give you more room to fill it in.

2. Use a putty knife to spread spackling compound or mixed joint compound and fill the crack or gouge. This should be at least 1/8 inch in length.

3. Place the fiberglass mesh over the crack. Press the tape into the compound.

4. Using a drywall knife, scrape off half of the compound and apply two more coats. Smooth the final layer of the compound with a rubber float.

5. Allow the compound to dry thoroughly. Once it has dried, the repaired section is ready to be painted over.
