The most common walls are plaster and drywall. The normal fasteners used to hang pictures and decorative items do not work well on either and result in unsightly cracks and holes. Walls will crack normally from settling and shrinking. Nails used to fasten plasterboard to studs will loosen because of moisture and occasionally pop out.

Popped nail heads:
Place additional nails above and below 1 ¾ inches popped heads. Re-drive the nails, until a “dimple appears” this includes the popped head. Clean the areas and fill the dimples with plaster and a wide putty knife. Leave until the plaster shrinks and re-apply more patching plaster. After drying, sand with fine sandpaper and paint.

Large Cracks
You will need to purchase a roll of patching tape. The large crack will not allow the plaster to stick. Clean the area of loose plaster. The crack is then filled with plaster and the perforated tape is pressed into the wet plaster with a wide putty knife. Smooth carefully and allow drying then lightly sand, and paint.

Small Cracks
If the cracks are small and narrow then you can fill them with patching plaster. Clean the area using an icepick or knife to make the crack larger. Clean off all dust and loose plaster, and dampen the crack. While filling the crack use a criss- cross motion. Feather the edges approximately 2 inches on each side. Dry and paint.

Gouge or small hole
1. Use a small piece of cardboard, in the center pull a piece of string with a knot at its end. Push it through the drywall hole by folding it in half. Now pull the string tight to hold the cardboard against the in-side wall. Using a putty knife apply patching plaster to the hole. Make sure the plaster goes behind the wallboard. Fill the hole until it is about 1/8 inch below the wall surface.
2. In about 5 minutes the plaster will begin to harden, you can then release the string. When the plaster has hardened, cut the string and score the surface with the edge of the putty knife. The topcoat will be premixed Spackle. Let the first coat dry then apply a second thin coat of Spackle. Feather it beyond the edge of the repair. Apply a coat of wall primer then paint.
