Raincheck Plus 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. Raincheck Plus does not block the pores of masonry, so water vapour is able to escape (thus preventing the “spalling” associated with less advanced products).
Raincheck Plus is a solvent-based formulation that is supplied ready-for-use. It is applied to masonry by brush or coarse spray.
Raincheck Plus is alkali-resistant, and can therefore be used in situations where other siloxane-based water repellents are not suitable – e.g. new concrete and newly pointed brickwork.
Raincheck Plus 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.
When considering the application of Raincheck Plus it is important to determine how exposed the site to be treated is in relation to wind speed. Treatments may fail at wind speeds in excess of 100 km/h. In these situations a rendered finish incorporating Oldroyd Xp Plaster Membrane should be considered.
Safeguard used to sell a concentrated masonry water-repellent called “Raindance”, which was diluted with tap water before use. This has now been replaced by Stormdry Masonry Protection Cream.
