Spackle, putty and epoxy wood filler are products that if properly used, can repair and eliminate unsightly defects and blemishes before a coat of paint is applied.
Spackling paste, also referred to as spackle is heavy paste filler typically consisting of calcium carbonate and chemical binders. It can be used on wood, drywall, and plaster to conveniently fill holes up to a half inches deep, small cracks, and other minor surface defects. Because spackle has a tendency to shrink, it is best to overfill the damaged areas. Once the paste has completely dried, it can be sanded to a smooth even surface. Spackling paste is designated for interior use, exterior use, or interior/exterior use.
Painter’s Putty is pre-mixed, ready to use, wood filler typically consisting of ingredients such as ground limestone, calcium carbonate, linseed oil, and titanium dioxide. It is well suited for interior and exterior use on new or previously painted wood to fill nail holes, small cracks, and other minor voids. Because of its dough like consistency, painter’s putty is not readily sand-able and does not function well as a surfacing compound. Painter’s putty should be allowed to dry to the extent that the surface has skinned over before a coat of paint is applied.
