Key specifications

Choosing the right option

For the liquid packs, for long-term results coat the converted surface with CRC Metal Armour as a protective primer coat. CRC Prep It and CRC Coloured Zinc can be used as overcoats.

The liquid is applied by brush, roller or sprayer and is not classified as dangerous goods. The aerosol is an extremely flammable aerosol, UN 1950.

Using it

Preparation: remove blistered, loose paint, other coatings and loose or heavy rust scale with a scraper or mechanical sander. Remove dirt, grease and oil from the surrounding surfaces and mask the surrounding area. Rubber gloves are recommended. Apply only at 10°C to 32°C.

Liquid: mix or shake well and pour the estimated amount into a clean container; it cannot be returned to the original container. Work it into the rusted surface with a synthetic bristle brush for maximum penetration, or use a roller or sprayer for large areas. Clean equipment with cold water immediately. Allow at least 12 hours cure before overcoating. Overcoat with an enamel topcoat; with a water-based topcoat, use a stain-blocking primer.

Aerosol: shake well. If the first coat does not fully convert the rust, apply a second coat once it is dry.

Test on a small inconspicuous area first.

Storage and handling

Liquid: store above 5°C and protect from freezing. Aerosol: keep away from heat and ignition sources; check the safety data sheet for storage limits.
