CRL Rockite® is a gray, hydraulic type cement that expands as it sets, and is specially formulated to produce unexcelled strength and bonding qualities. When mixed with water Rockite® pours into place smoothly, sets within 15 to 20 minutes, and when fully cured develops compression strengths in excess of 8000 pounds per square inch. Rockite® is great for any interior application. Use it to set railings, brackets, and other fixtures because it will not shrink, crack or dry out.
