Before applying Rapid Rock cement based anchoring product, remove all unsound concrete as well as grease, oil, dirt, laitance and other contaminants. Thoroughly saturate the concrete bonding area with water. Remove excess water and allow surface to dry slighting before placing grout. Note that holes should be at least 2 inches deeper and at least 1 inch later in diameter than embedded fixtures. Cavities and voids should be at least 1/2 inch deep. Mix the product according to directions and promptly pour mixture to avoid entrapment of air voids. Rapid Rock does not require special curing. In fact, air curing at ambient temperatures is all that's needed.
