NEO SILICONE
    PRODUCT CODE: SS20
    TECHNICAL DATA SHEET NO. 04-Repair & Renovation
    JULY 2009

  1. Product Description

    NEO Silicone (water repellent) is a deeply penetrating silicone resin solution, which helps to minimize the water and humidity absorption of masonry, concrete, unglazed tiles and bricks, as well as Kalksandsteine and fibre cement.
  2. Application Areas

    • Interior and exterior use.
    • Masonry, concrete, plaster, fibre cement walls, Kalksandsteine.
    • Unglazed bricks and tiles.
  3. Product Features

    • Reduces the water and humidity absorption of masonry, concrete, unglazed bricks and tiles, fibre cement and Kalksandsteine considerably.
    • Silicone resins penetrate deep into the substrate forming an invisible barrier. This prevents other substances and liquids from penetrating under the surface.
    • NEO Silicone should be used as a preventive treatment and coating. Should salt and other minerals be present in the plaster or floor screed, NEO Salt Stop (ss30) should be used.
    • NEO Silicone penetrates deep into the stonework and dries to an invisible coating. The product does not stain the substrate.
    • Unglazed tiles become water repellent. NEO Silicone is ideal for treating terra cotta tiles, slasto and terrazzo floors because, once treated, spilled liquids like alcoholic beverages and cool drinks can be removed from the floor surface without leaving stain marks.
    • Kalksandsteine treated with NEO Silicone do not absorb rainwater and the so called “cool house effect” is minimized.
    • Excellent penetrating, binding and water repellent properties.
    • Excellent adhesion.
    • Once sealed, can be top coated with a wide range of NEO Paints’ water and solvent based products.
    • For exterior use the water repellent effect lasts approximately 5 years - much longer for interior surfaces.
    • This product is not suitable for water proofing masonry based water storage tanks or dams with a high hydrostatic pressure.
  4. Product Data

  5. Application Details

    • Mixing Apply NEO Silicone un-thinned to porous substrates. The more porous the substrate, use more NEO Mineral Turpentine (mt00) for thinning.
    • Application Method Paintbrush or spray application. Roller application is not recommended.
    • Thinning NEO Mineral Turpentine (mt00).
    • Cleaning NEO Mineral Turpentine (mt00).
    • Application • Always apply two coats of NEO Silicone.
    • Allow to dry before over-coating with the required NEO Paints’ primer or topcoat.
    • Apply NEO Silicone un-thinned to porous substrates.
    • The more porous the substrate, use more NEO Mineral Turpentine (mt00) for thinning – this ensures invisibility of the repellent.
    • When dry (over night), repeat the procedure.
    • Only apply in areas with good ventilation and never eat, drink or smoke whilst using the product.
    • Apply with paintbrush or spray.
    • Roller application is not recommended.
    • If required, NEO Silicone can be over-coated with conventional paint coatings such as PVA paints and eggshell/gloss enamels.
    • Clean up application equipment with NEO Mineral Turpentine (mt00).
    • Do not apply before 09:00 and after 16:00 in the winter.
    • Do not apply exterior if it looks like rain will occur within 4-6 hours of application.
  6. Surface Preparation

    • Uncoated dry porous concrete/plaster surfaces
    • Uncoated fibre cement
    • Kalksandsteine surfaces
    • Unglazed bricks and tiles
    • Remove all dust, foreign material, fungal and algae growth.
    • Apply NEO Silicone un-thinned to porous substrates.
    • The more porous the substrate, use more NEO Mineral Turpentine (mt00) for thinning - this ensures invisibility of the repellent.
    • When dry (over night), repeat the procedure.
    • Allow to dry before over-coating with the required NEO Paints’ primer or topcoat.
  7. Colour Range and Quantities

    • Clear.
    • Available in 1 litre and 5 litres (20 litres on request).
  8. Precautions

    • Silicone resins are non-toxic and in no way harmful.
    • NEO Silicone is flammable during application with a flash point of 37 degrees Celsius.
    • Use only in well ventilated areas and do not eat, drink or smoke when applying this product.
  9. Disclaimer

    NEO Paints can not be held liable if the product fails due to improper surface preparation or application.
