Preparation and working conditions

Use above 4°C and avoid overnight freezing. Protect adjacent surfaces; do not use on polished marble, limestone or travertine. Thoroughly pre-wet the surface with water.

Best results at 4°C or above. Do not clean frozen surfaces or when overnight freezing is expected.

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.
