When an unsightly cement haze covers the facade, ILKA®-SZ (Hydrochloric acid free) can help. It can also be used to remove efflorescence and rust. The acidic cleaning concentrate dissolves the impurities of natural and artificial stones, concrete and clinker in the outdoor area completely without hydrochloric acid.
To do this, dampen the surfaces with water, apply ILKA®-SZ Hydrochloric acid free with a painter's puff or brush, allow to act for 10 - 15 minutes and wash off with cold water + brush or spray off with a high-pressure cleaner - done! So easy you come back to a clean facade.
Always read labels and product information before use.
1 liter units are supplied in bottles, 10 - 30 liter units in canisters, 120 - 220 liter units in barrels and the 1000 liters in IBC.
Pre-wet the soiled surfaces with cold water. Apply ILKA-SZ-Cement Film Remover free of hydrochloric acid with a painter's puff or brush until saturated, allow to act for 10 - 15 minutes. Then wash the surface with cold water and a brush. Alternatively, the surface can be washed with cold water and a high-pressure cleaner. ILKA-SZ free of hydrochloric acid can be diluted with cold water, but should be used undiluted in case of heavy soiling. It should be tested on a sample surface before application. ILKA-SZ free of hydrochloric acid is not suitable for marble, enamel and glazed, polished or finely ground stone surfaces, metals, aluminum, lacquers or acid-sensitive surfaces. ILKA-SZ must not be applied with a high-pressure device.
