DISSIPATIVE CURING AND COATING COMPOSITION FOR CONCRETE |
| 摘要 |
A coating composition for concrete that is an effective water barrier and that is relatively easily removed comprises an acrylic copolymer or a styrene copolymer 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.
