Abstract: A concrete laminate panel (1) comprising a sealant layer (2), a first layer of concrete (4), a second layer of concrete (6), and a backing board (8). The sealant layer (2) is a transparent, wear-resistant material, such as a urethane material. The sealant layer (2) provides a waterproof and alcohol-resistant layer with excellent wear properties, both in a dry and a wet condition, plus an ultraviolet filter to prevent yellowing. A two-stage, two-part polyurethane material comprises these properties, and we have found this material to be particularly useful as a sealant layer. The transparent nature of the sealant layer (2) allows the uppermost surface of the first layer of concrete (4) to be viewed therethrough. The urethane material contains an anti-microbial additive that will inhibit the growth of bacteria, fungi, molds, mildew, and algae. The first layer of concrete (4) provides a viewable thin, hardened, and decorative surface.
