Patching Nail Holes and Small Cracks
Some walls can be like a pin cushion with dozens of small nails or thumb tacks. After removal, all these holes must be filled with a suitable compound; donâ€™t rely on the paint to fill these small holes.
The best patching compound for small holes and cracks is light weight spackle.
Use your finger to fill the nail hole with spackle. After application lightly rub the surface to distribute the spackle and blend it with the surrounding surface. The same technique works for small cracks. A light sanding is recommended after the spackle has dried, typically 1 hour.
For larger nail holes or small dents use a putty knife to fill the area. After allowing the spackle to completely dry, lightly sand the area and blend the patch with its surroundings. A second coat can be applied after the first has completely dried.
