7 tips on Patching and Repairing Drywall - Small holes (such as nail holes) can be easily repaired with a small amount of spacklingcompound and a putty knife. Simply let the compound dry, sand over it, then prime and paint.
- Patching plaster should be applied in several layers for especially wide or deep cracks.
- To help strengthen a large patch, apply some fiberglass tape to the seams and then spackle over the tape.
- For large dents, allow the compound to dry overnight and then apply a second and even a third coat if necessary.
- Be sure to remove any high spots in the patched area with a fine sandpaper.
- Allow several hours drying time between layers.
- For larger holes in drywall you may need to build new backing. One easy way of doing this is to cut a piece of cardboard slightly larger than the hole and tie a string through the middle of it. Insert the cardboard into the hole and pull the string tight. While holding the string apply the first coat of patching. Once the first coat is dry cut the string and apply the second coat.
