Product Description

Teknos Rensa Terrace is a very efficient detergent for washing wooden terrace floors and garden furniture before wood oil treatment. It removes dirt, mould, algae growth and other impurities that prevent the wood oil from absorbing in to the surface.

Best Uses

Rensa Terrace can be used on all wooden surfaces which endure cleaning with water and are to be treated with wood oils, wood stains or exterior paints for wooden surfaces. It is a strongly alkalic detergent. It can also be used for pre-treating very dirty and chalked painted surfaces before maintenance painting.


Dilute Teknos Rensa Terrace with water depending on the purpose of its use:

For washing of and pre-treating surface to be painted: 1 : 1 (1 litre of detergent to 1 litre of water) For very dirty surfaces: use undiluted.

Wet wooden surfaces with water before applying the detergent. This prevents the detergent from absorbing too much and drying too fast. Apply the detergent to the surface to be cleaned by using either a brush or low-pressure garden sprayer. Note! Avoid splashing – the detergent may damage painted surfaces. Let it act for approx. 5 minutes.

Enhance the cleaning effect by brushing. The detergent must not dry on the surface to be cleaned - wet the surface again with the washing fluid, if needed. If the dirt is very embedded, a second treatment with Rensa Terrace may be required. Rinse the surface thoroughly with clean water. When using a pressure washer avoid excessive wetting of the wooden structures, such as weather boards and outer walls.

Let the surface dry for about 24 hours before painting or other treatment.
