A.    The Altro Whiterock system is designed to be fully bonded to the substrate using a quality, polyurethane all-over adhesive with a 5mm notched trowel to ensure you always get the best hygienic, robust, long-term solution. Inferior systems may use gunned or ‘dot and dab’ adhesive. This practice can leave a gap which traps bacteria between the sheet and the wall, undermining hygiene performance and also giving bugs somewhere to hide! Be aware that when temperatures change, the wall sheet can expand and contract. If sheets are applied using gunned or dot and dab adhesive the sheet can show surface rippling or even de-bond.
