RENSA STEEL

Washing agent for galvanized surfaces

»

RENSA STEEL is a very efficient citric acid based detergent for pretreatment of galvanized sheet-iron and zinc-coated steel surfaces before painting.

RENSA STEEL is a pretreatment agent for maintenance painting. It is meant for washing new untreated zinc-coated and galvanized steel surfaces before painting with paints for sheet-iron roofs. It removes very efficiently zinc salts, grease, dirt and other impurities. RENSA STEEL is a biodegradable product. 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).

Surface preparation

Remove loose dirt and dust from the roof by brushing.

Dilute RENSA STEEL 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. 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 approx. 10 minutes. Enhance the cleaning effect by brushing. 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 clean water.
