    Osmosana is based on lime and hydraulic binders, botticino, kaolin, silica aggregates, tartaric acid, different silicates and carbonates. It has no traces of resins, solvents and radioemissive aggregates.

    The hydraulic reaction of Osmosana produced by the natural chemical combination, of water lime and kaolin (metakaolin or industrial cocciopesto (lime mortar with crushed pottery)), also called "superpozzolanic" reactivity, is comparable to the hydration reaction of cement materials, but in ecological building key.

    Fields of application
    Waterproofing treatments of brick or mixed external walls, provided they are sufficiently porous and absorbent and free from any waterproofing and / or water-repellent surface treatment, whether chemical (siloxanes, epoxies, polyurethanes, etc.) or natural (wax-up), before backfilling. Anti-capillary rising damp treatments in the construction of subbase screeds.
    Allowed supports
    Mixed walls (bricks and stones)
    Stone walls
    Preparation of supports
    Application surfaces should be clean, free of soiling, crumbling and non-adhering parts, dust, etc., water repellent treatments in general, etc. conveniently saturated with water until they reach the condition "saturated with dry surface".
    Mode of use
    Pour about 2/3 of the mixing water into the mixer, add Osmosana and the remaining water; continue to mix until a homogeneous lump-free mixture is obtained. After mixing is completed wait a few minutes before applying.

    Apply on site with a brush, spatula or roller, depending on the desired result. The mixing water indicatively necessary is 24-36% by weight (6-7 litres/bag for applications with the spatula, 8-9 litres/bag for applications by brush or roller).
