Designed for the treatment of metal surfaces to remove corrosion or rust. It transforms corrosion products and inhibits the corrosion process on various surfaces and products made of steel and cast iron with a rust layer thickness of up to 80 µm. It reacts with rust products, modifies them, and transforms them into a supportive layer for painting. Thanks to the presence of active zinc ions, it provides additional surface protection and extends the service life of steel products. Application method: Shake well before use. Clean the metal surface from loose (peeling) rust. Apply the product to the surface with a brush, roller, or spray method at an ambient temperature not lower than +10°C on a dry degreased surface in two layers with an intermediate drying time of about 30 minutes. The surface can be painted after the complete drying (at least 30 minutes at a temperature of +20°C). Temperature range of use: from +10°C to +30°C. Volume: 1 liter. Composition: Deionized water ≥30%, inorganic acid 15-30%, zinc salts ≤5%, functional additives ≤5%.
