Fixing Thin slate Veneer cladding panel sheets
We recommend a product called Ultrabond S997 1K which is produced by Mapei and available from most builders merchants or timber stores as it is part of their wood flooring range but has been proven to be the best product at this moment in time for attaching securely to surfaces it comes in a sausage type packet containing 600ml for use with a application gun. One sausage should cover an area of approx 2 sheets. Fully cover the surface you are going to clad with the adhesive spreading the glue around with a 3-5mm notched trowel, the panels will stick to this instantly but still giving a little movement to adjust into the final resting place.As always follow the manufactures guide when using this product.
