QA Aqua Rainguard
A chemically crosslinking siloxane / silane complex emulsion that provides a water repelling protection for exterior masonry & brick walls. Once applied to the surface it hydrolyses & is converted into a silicone water repellent. Reduces the capillary absorption of the building which it has penetrated, but does not clog pores or capillaries. Therefore there is little or no impairment of the building materials ability to breathe.
Benefits

Surface Preparation
Clean surface of al contaminants using water blasting or hosing & scrubbing if the surface is dirty & contaminated. QA Aqua Rainguard needs to penetrate into the surface to do its job.
