Iso Water Stop Isocolor® is a ready-to-use water-repellent protective treatment based on a non-film-forming siloxane emulsion, specifically designed to protect mineral surfaces and building materials from water penetration and weathering.

It penetrates deeply into the substrate without altering its appearance, creating an invisible barrier that significantly reduces water absorption and limits deterioration caused by rain, humidity, frost and atmospheric pollution. Thanks to its high resistance to alkalis and its rapid water-repellent action, it helps preserve the integrity of treated surfaces over time.

Iso Water Stop protects the substrate against the formation and growth of mould, moss, algae, fungi and bacteria, improving the durability of façades, claddings and surfaces exposed to external agents. Its non-film-forming formulation preserves the material's breathability, allowing the natural release of water vapour.

Ideal for the protective treatment of plasters, natural stone, concrete, facing bricks, cement-based coatings and mineral surfaces exposed to water and moisture.
