Waterblock is a ready-to-use, non-silicone, mineral solvent-based, colourless water-repellent impregnating agent for hydrophobic impregnation and surface protection of walkable floors. Waterblock penetrates the substrate and reacts with carbon dioxide in the air to form an internal water-repellent barrier. This reaction takes place as the solvent evaporates from the vehicle. Waterblock leaves no surface film and does not alter the colour or characteristics of the treated material. The depth of penetration depends on the hygroscopic characteristics of the substrate, bearing in mind that more porous materials have a greater capacity for absorption. This allows protection over time without the risk of surface deterioration. Waterblock prevents water permeability but allows water vapour transpiration. This is possible because the microporosity of the substrate is not completely occluded. In fact, it is well known that water molecules in the liquid state are aggregated, while in the gaseous state they have ample freedom of movement. Laboratory tests show that treatment with Waterblock responds to this principle, just as it has been observed that some treated surfaces (even after a few days) can release traces of moisture with consequent surface deposits of salts. This does not mean that the treatment is ineffective, it is simply a phenomenon due to the moisture contained in the sub-layer which, as it evaporates, tends to release certain salts (such as sodium sulphate and potassium sulphate) that crystallise on the surface.

Waterblock is a specific product for the waterproofing treatment of walkable surfaces subject to water infiltration (balconies and terraces). It is suitable for ceramic floors, porcelain stoneware, stone, klinker, terracotta, mineral surfaces and wood. Waterblock is a penetrating, safe and effective product that leaves no surface marks and does not alter the material characteristics and colour of the treated surface. It has proven efficacy for long periods (up to 10 years) without loss of functionality.
