Valspar® Block Filler Primer

This fast-drying filler seals porous masonry surfaces. It fills the voids in cement and cinder blocks, reducing the amount of finish coat needed to coat such surfaces and provides an ideal primer surface for latex and oil-base topcoats. Formulated for professional painter use in residential, commercial, institutional and industrial applications. NOTE: Exterior use requires topcoating with exterior paints for maximum performance.
