The Custom Building Products Fix-It-All Patching Compound is a must-have for paint tools and supplies. It helps in patching cracks and holes in plaster, wallboard, wood, brick, and concrete. It has a strong bond and does not shrink. The patching compound can be sawed and drilled when hard. The fiber reinforcement allows the Fix-It-All to be sawed, drilled, filed, or sanded after drying.
