These sponges prevent debris from accumulating on the abrasive surface and keep operating temperatures low. Flexible enough to sand around curves and in corners, these sponges provide the comfort and control of a sanding block.

Sponges with Stearate Coating—A dry powder lubricant applied to the surface reduces friction and heat buildup, which reduces wear on the abrasive.

Sponges with Channels—Raised, brick-shaped layers of abrasive material let you achieve highly consistent finishes. Widely spaced channels in between the bricks prevent clogging by collecting and redirecting debris away from the abrasive surface. This makes these sponges good for coarse sanding applications, but they are not as good for fine finishing as sponges with stearate coating. Style B have larger layers of abrasive material than Style C to abrade surfaces more quickly, but they have fewer channels and handle a moderate amount of dust. Style C sponges have more cleaning channels than Style B, making them good for sanding surfaces that generate a large amount of dust.

36 and 60 Grit—Use for paint stripping.

80-150 Grit—Use for bare surface sanding.

180 and 220 Grit—Use for sanding between coats of paint.

The long sides of these sponges are angled to get into corners and edges that a flat sponge might miss. Flexible enough to sand around curves and in corners, these sponges provide the comfort and control of a sanding block. The abrasive is one grit on the top and one side, and another grit on the bottom and the other side.
