a.Fill the pores and voids of concrete block to create a smooth base for topcoats
b.Add gloss to the final finish
c.Waterproof wood siding
d.Replace the need for a topcoat

Concrete masonry units are porous with open voids, and a high-build block filler fills those pores to create a uniform, smooth surface. This reduces topcoat consumption and improves appearance and moisture resistance. It is applied before the primer or finish coats on block walls.
