Breathable anti-vegetative water-repellent for stone, marble, terracotta, and klinker. Natural effect 1AS. It is a water-repellent protective agent with high penetration, ideal for creating a barrier against water absorption without blocking the natural transpiration of the materials.
It does not alter the color of the substrates and can be used in all cases where absorption and retention of rainwater cause humidity problems such as salt efflorescence, mold, and algae, which lead to premature deterioration of materials, while simultaneously reducing the risk of frost flaking. 1AS is ideal for protecting floor joints. Ready to use.
Coverage 6/12 sqm/liter depending on the absorption level of the substrate. It is recommended to apply two coats with at least 4 hours between each application.
