  • Preparation : All surfaces to be treated with CX WATERSEAL WH must be thoroughly cleaned by a wire brush or other mechanical means, to remove all dust, laitance or debris. The surface must also be free from oil, grease, wax or any other form of foreign matter which might affect adhesion. Spalled and deeply disintegrated concrete or mortar must be removed to a sound substrate and repaired suitably before coating.
  • Mixing Ratio : For white colour - mix white cement, for other colours; add cement compatible pigments to white cement.

  • Priming : Before application, the surface should be primed with CX WATERSEAL WH as follows:
    1 part of CX WATERSEAL WH: 2 parts of Water: 4 parts of Cement Mixed material with the above proportion will cover an area of 16-17m2 for 1L of CX WATERSEAL WH.
  • Topcoat : CX WATERSEAL WH acrylic polymer shall be mixed with neat cement in the ratio of 1:2 respectively, to obtain uniform and consistent slurry avoiding any lump formation. This can be achieved with a low duty, low speed drilling machine attached with a mixing paddle. Do not mix for more than 2 minutes. Do not mix more material than which can be used within the pot life. Retempering the mix with water should not be done.
    Occasionally stir the material till the entire quantity is applied, so that solids do not settle at the bottom of the containe.
  • Application : For best results, wet the surface before coating. Apply the mix with a short, stiff bristle brush like paint to an approximate thickness of 1 to 2mm, during the first 12 hours of curing, CX WATERSEAL WH surface must be protected from abrasion, rain or other adverse conditions. No traffic shall be allowed within 48 hours after application. Normally 2 coats of application of CX WATERSEAL WH are recommended. First coat should be allowed to air dry for 5 – 6 hours. After application of the final coat, initial air drying shall be allowed for 2 to 6 hours. During this period water should not be used for curing. Moist curing should be done for the next 24 hours by spraying water on CX WATERSEAL WH coating. Following moist curing, CX WATERSEAL WH should be allowed to dry for three days before subjecting it to submersion in water.
  • Packaging : Available in 1, 5,20, 50 & 200 LITER packs.
  • Coverage :
    Priming coat: 16-17 m2/L/COAT
    Topcoat - 4.5 - 5.0m2/L/ coat.
    However the practical consumption varies depending on the texture and porosity of the surface and the application thickness.
  • Storage : CX WATERSEAL WH liquid has a shelf life of 12 months, when stored in unopened containers under normal warehouse conditions.
