Lightweight Spackle
This article is about the newer
light weight spackles (Sherwin Williams C-77, Red Devil One Time Spackle etc….). You can still buy the older oil or latex heavy spackles, but they are not used much anymore.
Spackle is a surfacing or patching compound that differs from drywall compound in that it is not re-wetable once it dries and will not dissolve with water (as drywall compound will). Spackle feathers out finer than drywall compound and the new light shrink free versions do not shrink.
Advantages of spackle.
Spackle is for the most part “shrink free”. The benefit of not shrinking is that you can often fill small / shallow repairs in one or at worst two applications. The fine feathering allows tight to the wall fills that often don’t need to be sanded or sanding is very minimal.
Spackle is quick drying. Sherwin Williams C-77 can usually be recoated in 30 minutes to one or two hours. Spackle is a good pre-paint patching material. Sands fairly well (drywall compound sands better and easier), and is re-coatable with either latex or oil paint once dry.
Uses for spackle
Most lightweight modern spackles are interior and exterior products. They are primarily used on interior drywall, but can be used to fill nail holes in wood trim. Spackle is not intended to be used to float drywall joints. Use spackle for dents and nicks and small repairs, use either chemical setting or regular joint compound for drywall joints.
Spackle is not intended to be used on joints or cracks that will expand and contract or “move”, or the rubber crack spray. Use caulk for gaps in wood trim and between trim and drywall.
Spackle is used for it’s quick dry pre-mixed, non shrinking advantages. Drywall compound on the other hand is used for larger and deeper surfacing when multiple coats can be applied over a few days time to take advantage of the easy sanding properties of joint compound.
Spackle works well in bathrooms because it is not as affected by moisture as regular drywall compounds are.
Most spackles do not need to be primed, you can paint over them directly with your finish paint after removal of all sanding dust. If you are using a sheen paint , in order to get good sheen uniformity , you will have to spot prime to prevent gloss absorption and a flat spot. Don’t use a stain blocking (stain kill) for spot priming because you will get “shiners” on the spot priming where the paint will be too glossy. The best type of primer is the finish paint itself or a PVA (polyvinyl acetate) new drywall type of primer.

What is spackle?
Filling nail holes
Spackle is used on new wood trim instead of "putty". Oil based putties will cause staining (and adhesion problems in some cases) when used under latex trim paints.
Spackle will not cause staining, and will fill nail holes in one application because it does not shrink.
