Teknos Rensa Anti-Mould is an environmentally friendly and biodegradable substance which kills mildew, lichen and algae growth from the external surfaces of buildings.

Best Uses

Teknos Rensa Anti-Mould can be used on all constructional surfaces, which endure cleaning with water: wood, concrete, bitumen sheet, plaster etc. and old painted surfaces. It works extremely well on porous surfaces where it gets to absorb in, for example concrete roof tiles and paving tiles, bitumen roofing felt, plaster, press-impregnated wood.

It can also be used together with Teknos Rensa Façade cleaner on pre-treating badly mildew growth contaminated surfaces before they are repainted.

It is easy to spray on e.g. tile and felt roof, stone paving, brick wall or fence and let the growth be removed by the effects of weather. Teknos Rensa Anti-Mould also disinfects the surface and gives a long-term protection.


Dilute Teknos Rensa Anti-Mould with water depending on the purpose of its use: For surface protection and pre-treating before painting: 1 : 5 (1 litre of detergent to 5 litres of water) For very dirty/mildewed surfaces: 1 : 2.

Mildew Protection

Remove loose dirt and other matter from the surface by e.g. brushing. Apply protection against mildew to the surface to be cleaned by using e.g. a brush or low-pressure spray (so-called garden spray). Do not rinse. Weathering actions, wind and rain will remove dead and dried growth.

Pre-Treating Surfaces Before Painting

Wet the porous and absorbing surfaces with water before cleaning. Apply protection against mildew to the surface to be cleaned by using e.g. a brush or low-pressure spray (so-called garden spray). Let it act for about. 2 days. After that wash the surface with Teknos Rensa Façade cleaner.
