Concretis Polished Concrete Veneer flooring Concretis Polished Concrete Veneer flooring is a veneer, concrete overlay that looks like polished concrete. The Concretis Polished Concrete Veneer overlay is laid over existing surfaces at a finished depth of 10-12mm. It is a seamless flooring which means there is no need for joints or grout, providing a stylish finish that is very easy to maintain. Concretis Polished Concrete Veneer flooring is a unique system which provides a consistent look throughout and due to the installation method the finish will be free of boot prints, water damage and screed marks which can occur when traditional concrete placement is undertaken. Designed to adjoin to other flooring (such as tiles, timber, carpet), therefore no set-downs are required on new constructions.
