To be read with Preliminaries / General conditions.
170 MASONRY COATING
Raindance Water-Repellent for Masonry (solvent free)
Raindance is a concentrated colourless water-repellent for masonry based on UV resistant siloxane resins. Raindance can be used on old and new buildings to protect against penetrating damp and to keep masonry clean. Raindance will not block the pores in masonry so water vapour is able to escape.
Wooden and metal window/door frames and glass surfaces should be covered up before treatment, since removal of silicone resin splashes after drying can be very difficult.
Raincheck Plus Water-Repellent for Masonry (alkali-resistant)
Raincheck Plus is a colourless water-repellent for masonry based on UV resistant siloxane resins. It is alkali resistant and can therefore be used in situations where other siloxane-based water-repellents are not suitable; on newly pointed brickwork for example. Raincheck Plus can be used on old and new buildings to protect against penetrating damp and to keep masonry clean. Raincheck Plus will not block the pores in masonry so water vapour is able to escape.
Consult Safeguard Europe Ltd technical literature for details. Safeguard Europe Ltd can also provide a design and specification service and it is recommended that they are consulted early in the design process.
