4L Aquellux S Masonry Water Repellent

A silane/siloxane solvent-based water repellent for external use that does not alter the appearance of the surface (some slight surface colour change can occur depending on the porosity and type of substrate). Used to make concrete, brick, stone, and other mineral surfaces water repellent whilst allowing trapped moisture to escape from the substrate. Excellent penetration depth. Highly stable on concrete and other surfaces containing cement. Used to treat vertical and inclined surfaces such as walls and roofs. Use on concrete, cement plaster, block work, bricks, roofing tiles, cement asbestos and fibrous cement, GRC panels and natural stone (test substrate for suitability before use). Porous concrete blocks may not be suitable for treatment.
