Abstract
A curing composition for concrete that is an effective water barrier and that is relatively easily removed contains an acrylic or a styrene polymer latex and a polysaccharide. The polysaccharide makes the coating composition susceptible to enzyme action and thus easily removable by flooding the surface of the coated concrete with a dilute solution of enzyme reactive with the polysaccharide.
