The special gel composition is designed for treating metal surfaces in order to remove corrosion or rust. It protects the treated surface from subsequent atmospheric and climatic influences. It passivates the metal surface, transforming corrosion products into a solid coating that can serve as a base for painting. Usage instructions: For best results, it is recommended to use at an ambient temperature of not lower than +10°C. Clean the surface to be treated from loose rust using a metal brush. Shake the can well. Apply the product to the surface using a brush or sponge. Repeat the treatment after 10-15 minutes. Allow the composition to work for 30-40 minutes. Rinse with plenty of water and dry the treated surface with a cloth. Paint should be applied no later than 2 days after treatment. Precautions: Caution! Contains acid. Work with the use of personal protective equipment (gloves, goggles) in a well-ventilated area. Volume: 250 ml Composition: Desalinated water >30%, orthophosphoric acid ≥30%, oxethylene diphosphonic acid <5%, corrosion inhibitor <5%, thickener <5%.
