Osmotic two-component type weatherstrip adhesive cement

A two-component, certified cementitious adhesive based on hydraulic binders free from harmful additions, with modifying and flexibilising resins, selected siliceous and calcareous sands, reactive fillers with high pozzolanic activity and cellulosic thickeners, perfect for the preparation of adhesive mixtures that are trowelable with high deformation and impermeability capacity. Ideal for bonding coatings of any kind, even with low absorption, on horizontal and vertical surfaces, both internal or external, including with low porosity (for example, coatings on indoor swimming pools).

    Fields of application
    Bonding tiles, waterproofing and anti-humidity coatings, structures and masonry exposed or underground 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). Bonding small vitreous tiles for swimming pools. Bonding tiles on Osmocem Flex or Osmocem D type osmotic coatings on terraces and balconies.
    Allowed supports
    Cement-based or lime-based mortars
    Floor screed
    Porous stone
    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
    Mix the powder component (component A) with the hydrating solution (component B) with a drill at a low number of revolutions, pouring the powder progressively in the liquid, continue mixing until a homogeneous lump-free mixture is obtained. After mixing is completed wait a few minutes and stir again before proceeding with the application.
