Sovereign Water Repellent is based upon the active ingredient polyoxoaluminium stearate in an aliphatic solvent and is designed to prevent penetrating damp. Sovereign Water Repellent can be applied by brush or spray onto brick, stone, concrete, masonry and other porous surfaces. Sovereign Water Repellent meets the requirements of BS6477:1992 – Specification for Water Repellents for Masonry Surfaces.
After curing, Water Repellent will produce an invisible hydrophobic barrier. Treated surfaces will repel water, however the vapour permeability will be unaffected, allowing the walls to breathe. Liquid Water Repellent will prevent penetrating damp and reduce the risk of damage caused to masonry by the freeze/thaw cycle.
