About Teknos Rensa Galvanised Steel Cleaner

It is a pre-treatment agent for maintenance painting.
It is primarily for washing new untreated zinc-coated and galvanised steel surfaces before painting with a relevant paint for sheet-iron roofs.
It removes zinc salts, grease, dirt and other impurities.
Rensa Galvanised Steel Cleaner is also suitable for washing of previously painted sheet-iron roofs before maintenance painting.
Rensa Galvanised Steel Cleaner is environmentally friendly and biodegradable.
It meets the requirements by OECD and by the Detergent regulation of European Parliament and the Council on detergents for biodegradability (OECD 301B, EC 648 / 2004).
Direction For Use
Dilute Rensa Galvanised Steel Cleaner with water depending on the purpose of its use:
For washing of and pre-treating surface to be painted: 1:3 (1 litre of detergent to 3 litres of water)
For very dirty surfaces: 1:1
Remove loose dirt and dust from the roof by brushing. 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 e.g. a brush or low-pressure spray (so-called garden spray). Let it act for about 10 minutes. Enhance the cleaning effect by brushing strongly.
NB: 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.
Rensa Galvanised Steel Cleaner is an efficient, but environmentally friendly and biodegradable product. However, using the detergent must be followed with a reasonable caution.
Avoid skin contact and breathing the spray mist. Protect eyes from splashes. See Material Safety Data Sheet.
The detergent may harm garden plants – avoid unnecessary splashing.
The most sensitive plants can be covered or wetted with water before the treatment.
