Raincheck LS


A colourless water repellent for limestone based on UV resistant silane-siloxane resins. The composition of Raincheck LS allows the water repellent material to bond to the carbonates in limestone. Raincheck LS can be used on old and new buildings to protect against penetrating damp. The product is suitable for the treatment of absorbent limestone rather than less absorbent dense limestone.

To be applied by a suitably qualified contractor.
