BS H2O is a special water-repellent emulsion made with reactive resins dissolved in water. Its special formulation, specifically developed to be applied on the bottom of the tiles and slabs, creates a protective membrane that prevents humidity from rising through the material, without, however, affecting its original breathability and at the same time, increasing the adherence between the treated material and the adhesives used to install it.
BS H2O is used as a back treatment before installing any of those materials subject to rising humidity and all of the problems linked to it. BS H2O is always used in combination with a Faber pre-installation treatment applied to 5 sides (top+edge) to guarantee maximum protection and perfect adherence with any type of bonding agent.
BS H20 can also be used as a bonding additive together with cement-based products to create mortar with the best possible chemical and mechanical resistance and adherence, even to old surfaces in bad condition.
