A water-repellent breathable treatment designed to protect masonry surfaces from water penetration without altering the natural appearance of the structures, as it becomes transparent when cured.

This solvent-free material prevents spalling and cracking of surfaces such as concrete, stone and brick, while reducing dirt retention. It is supplied as a concentrate, which can be easily diluted on-site with water and applied by brush or spray to provide long-term protection and maintain building fabric insulation properties.
