Coo-Var Rust Converter will protect surfaces from further corrosion by allowing the application of topcoats onto substrates where rust cannot be fully removed.

It is a water based coating for use on iron and steel surfaces. This product will turn any rust on the substrate into a stable surface allowing the user to then be able to coat the substrate without the risk of any further corrosion.

Surface Preparation

Surfaces should be clean and free from surface dirt, dust and grease. Light to medium rusted steelwork must be properly prepared by wire brush or power tools (SSPC SP3) to remove loose millscale and flaky rust or paint, which is not sound or tightly adhered. Weathered steel should be high pressure water or wet abrasive blasted to SSPC SP6. Best results are achieved if some bright metal (10%) is showing in the rusted area.

Mixing Instructions

Stir or shake lightly - Do Not Thin.

Application Conditions

Apply when humidity is between 40 and 90% and the temperature is above 5°C. On warmer days it is recommended to damp down warm steel surfaces with a mist of water prior to application.

Preceding Coat

Apply direct.

Subsequent Coat

Coo-Var Zinc Phosphate Primer.


When using Coo-Var Rust Conveter, always decant into a separate container and never return surplus material to original bottle. The product is best applied by brush or deck scrubber to encourage penetration of rusted surfaces.
