Teknos Rensa Roof is an efficient detergent for the washing of tile roofs and previously painted very dirty sheet-iron roofs.
Best Uses
Teknos Rensa Roof is a pretreatment agent for maintenance painting. It is primarily meant for washing old tile roofs before painting with Teknos Kirjo Tile paint for tile roofs. It removes very efficiently both dirt and algae as well as lichen growth. It is also suitable for washing painted very dirty sheet-iron roofs before maintenance painting.
Application
Dilute Rensa Roof with water depending on the purpose of its use:
For washing of and pre-treating surface to be painted: 1 : 6 (1 litre of detergent to 6 litres of water)
For very dirty surfaces: 1 : 3
Remove loose dirt, moss and growth from the roof by brushing and/or using a pressure washer. Wet the tile surface 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 a brush or low-pressure spray such as a garden spray. Let it act for around 20 minutes. Enhance the cleaning effect by brushing strongly.
Note: The detergent must not dry on the surface to be cleaned - wet the surface again with the washing fluid, if needed.
Rinse the surface thoroughly with a plenty of clean water by using a pressure washer.
