Description
Hamrit Rust Gurd" appears to be a misspelling of "Hamrit Rust Converter," a product for treating and priming rusted iron and steel. The company that manufactures it, Metachem Industries, is based in Karachi, Pakistan.
How it works
Hamrit is a rust converter, not a rust remover. Instead of scraping rust off the surface, it uses a chemical process to change it.
It converts rust (iron oxide) into an inert, stable black substance called magnetite.
It then creates a zinc phosphate coating that provides a base for paint and resists further corrosion.
Hamrit's one-step process is considered a more eco-friendly alternative to sandblasting.
Key features and uses
Application: Can be applied using a brush, roller, or spray.
Water-based: It is non-flammable and cleans up easily with soap and water.
Versatile: It is used in automotive, industrial, marine, and household applications.
Base for paint: The resulting finish creates a strong bond for oil-based or water-based topcoats.
Drying time: The surface typically dries in 4–6 hours at room temperature.
How to apply Hamrit
Prepare the surface: Make sure the surface is degreased and free of contaminants. Remove any loose, flaking rust with a wire brush or scraper.
Apply the product: Brush, roll, or spray a liberal, even coat of Hamrit onto the rusted area.
Allow to dry: Wait 4–6 hours for the product to react with the rust and fully dry.
Finish: Apply a layer of paint or oil to the treated surface as required.
