<p>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. The first layer of concrete ( 4 ) is wet bonded and cross-cured to the second layer of concrete ( 6 ). The second layer of concrete ( 6 ) comprises a fiber-reinforced concrete material and provides improved tensile strength for the laminate concrete panel ( 1 ). The backing board ( 8 ) may be any suitable fibrous board, such as MDF. The backing board ( 8 ) is bonded to the second layer of concrete ( 6 ).</p> |
