Equipment
Apply with a low-pressure sprayer (maximum 3.4 bar), roller or masonry brush. Do not atomize or use high pressure for application; rinse thoroughly after cleaning.
Practical advice
Test a representative area with the equipment and preparation planned for the job. Let it dry before assessing the result and coverage.
Rinse thoroughly to remove all cleaner and residue. Where pressure washing is unsuitable, use plenty of clean water with a sponge or soft brush and collect the rinse water. Work bottom to top on vertical surfaces and ventilate interior areas.
Clean tools with fresh water before the product dries. Immediately wash splashes off glass, aluminium and other adjacent surfaces.
