3 x 1.7 Raindance.
£342.00 Regular Price
Raindance is a colourless water-repellent for masonry based on UV-resistant siloxanes. It can be used on old and new buildings to protect against rain penetration (penetrating damp) and to help keep masonry clean. Raindance does not block the pores in masonry so water vapour is able to escape (thus preventing the "spalling" associated with less advanced products).
Raindance does not affect the natural finish of the substrate (although some darkening may appear). However when rainwater lands on the treated surface it will form droplets and run off, rather than soaking into the substrate.
Raindance is supplied as a concentrate that is diluted with tap water before use. It is applied to masonry by brush or coarse spray.
The performance of Raindance is affected by highly alkaline substrates such as new concrete and newly-pointed brickwork. Where these substrates are to be treated, the concrete / mortar should be allowed to cure for at least 28 days before Raindance is applied
