Fluted silicon carbide rub bricks makes dressing down concrete fast and easy. The 8" x 3-1/2" brick is fluted on a diagonal, which provides long, sharp edges to help with stubborn materials while carrying away the excess debris. The 1-1/2" thick 20 grit rub brick smooths out concrete to a fine finish. Attached to a contoured plastic handle to minimize fatigue. Preferred by cement finishers and masons for its ease of use. A popular tool to create a smooth professional finish on block walls, wet tile, and concrete, especially excess cement from forms. The favorite tool for decorative concrete prep and applications. Proudly made in the USA.
