It can be laid over galvanized netting or safety mesh, but must be separated by a 5mm barrier of inert non-absorbent, non-reactive material. SUPPORTING STRUCTURE Supporting structure should be designed in compliance with NZ 3604 or AS/NZS 1170 to ensure structural integrity. Surfaces should be clean of grease and dirt that may mark the backer coat and incompatible materials that may cause corrosion.
