Water and pollutants transported by water are the worst enemies of construction (corrosion of metal reinforcement structures, growth of algae and fungus). Many building materials are porous like concrete and natural stone. Everdrai prevents the absorption of water as well as oils and dirt, while maintaining the natural appearance of the substrate. Water slides on the treated surfaces without penetrating them. Breathable, allows the flow of water vapor. Application: Apply by roller, brush or spray gun. Allow a thin liquid layer to form while spreading. Apply at least two layers, using the “wet on wet” technique: when the first layer has been absorbed and stops shining, apply the next layer without waiting for long periods of time. *Test prior application in a small hidden area. In some exceptional cases it can alter the color of the stone. *Do not use aggressive cleaning products (acids, alkalis or cationic surfactants). *If splashes occur in unwanted areas, clean with water immediately. Drying time: 1-2 hours Results: The hydrophobic effect develops in 24-48 hours Approximate returns: 20-0.3 m2 / l (natural stone) 3-10 m2 / l (fiber cement) 3-0.5 m2 / l (brick) 2-4 m2 / l (concrete) 5-7 m2 / l (single layer mortar) 1-2 m2 / l (plaster)
