Areas Of Usage: 

Spackle is suitable for using on both exterior and interior surfaces. It can significantly heal the chasms and holes in plaster, painted metal, wood, masonries, and others. Simply, spackle has no boundaries to be used on for mending defective spots. 

However, the wood filler has a limited area of being used. It’s better suited for wood only. Very occasionally it can be used to repair drywall but it’s not so effective. Also, can’t effectively be used on exterior areas. 

Composition Of Materials: 

Wood fillers are a combination of elements including clay, polyurethane, and epoxy. All of these materials create a great repairing element that fabulously works on healing crevices and gouges in the wood.
