Spreading rate 4 - 8 m²/l
Drying time The drying time for wet layer thickness 200 µm 20° C / 65 % RH: Touchdry after 1-2 hours, Dry after ~4-6 hours, Fully cured after ~6 days. The drying time depend on layer thickness, temperature, relative air humidity, and air circulation.
Pretreatment/cleaning Clean the surfaces from dirt, dust and salts. Clean the surface with Iso A-Clean according to instructions. The surface must be totally dry, clean and absorbing to ensure good penetration. Soak the surface with HydroBlock SB till saturation point by spraying “wet on wet”. HydroBlock WB must be applied in 1 – 2 “layers” in order to obtain the best result. Avoid application of the product in presence of strong wind or rain as this may cause stains or blotches. A surface already treated with a water-repellent product will not allow the penetration of other impregnating agents (hydrophobic solvents). Liquid not absorbed can cause stains on the surface – these are very difficult to remove. All splashes, if any, must be wiped away from windows immediately. It is recommended to cover windows before applying HydroBlock SB. Newly plastered or rendered walls must be fully hardened and dry before the application of HydroBlock WB.
Environment Avoid spillage into drains, water systems and soil. Destroy liquid waste according to the local regulations. Recycle or dispose of empty, dry cans in accordance with local regulations.
High “water-pearling” effect. Allows water vapour coming from inside the structure to pass through. Reduces salts moving to the surface of the structure. Does not form a superficial film. Reduces the growth of algae and green discolouration. Prevents frost damages.
