Altro Whiterock offers an easy to clean, impact resistant and grout free wall finish that meets all current EU directives on health and hygiene. By comparison with traditional ceramic tiling where grout can absorb grease and oil, Altro Whiterock is fully bonded with all edges and abutments sealed, remaining air and watertight so that no contamination can get in between the wall finish and wall. Altro Whiterock has also been tested to BS EN438-2-1991 Drop Ball Test and found to have a high impact resistance, outperforming ceramic tiling by a considerable margin.
