Expands As It Sets Fast-Setting Dozens of Adhesive and Repair Uses CRL Rockite is a gray, hydraulic type cement that expands as it sets, and is specially formulated to give it unexcelled strength and bonding qualities. When mixed with water, it pours into place as smoothly as molten lava. It sets within 15 minutes, and within one hour, it develops a compression strength of 8,000 pounds per square inch. When fully set, Rockite grips metal to concrete permanently. Use it to set railings, brackets and other fixtures because it will not shrink, crack or dry out. It has excellent durability to weather extremes and chemicals, so it can be used to set and grout tiles and mosaic pieces. It is also used to fasten terminal wires and posts in electronic assemblies and insulators. Rockite is a versatile adhesive cement with dozens of uses.
