CRC Blue Zinc Anti-Corrosive Satin Enamel Coating 400ml Aerosol

CRC Coloured Zinc is a zinc enriched satin enamel coating in an aerosol. CRC's data sheet says high levels of anti-corrosive zinc complexes are embedded in a resin system, forming a quick-drying enamel coating with adhesion to bare metal.

This listing covers Blue (CRC product number 2097) and White (CRC product number 2090), both 400ml aerosols. The CRC range has seven colours; only these two are listed here. CRC also describes a coating system: CRC Zinc It as primer, CRC Prep It as an intermediate coat if a high film build is needed, and Coloured Zinc as the finish coat.

Selecting the right option

CRC recommends priming with CRC Aerosol Zinc It Galvanic Rust Protection 350g and using CRC Prep It Anti-Corrosive High Build Easy Metal Primer 2114 - 400ml as an intermediate coat when a high film build is wanted. The other colours in the CRC range are on CRC Zinc Rust Protection.

Using it

Surface preparation per CRC: remove signs of corrosion with a wire brush or emery paper. If rust cannot be removed, treat the surface with CRC Rust Converter after thoroughly abrading the rusty areas. Clean with CRC Brakleen or a similar degreaser if required, and where possible abrade with disc grinding, wire brush or sandpaper.

Shake the can until the agitator ball is moving freely, then for at least 1 further minute. Apply a number of thin coats with smooth even strokes to a clean, dry surface, holding the can approximately 25cm from the surface.

When finished, clean the valve by turning the can upside down and pressing the button until only pressure escapes. Clean up with mineral turpentine or white spirits.

CRC's data sheet gives two recoat statements: the application data says overcoat within 1 hour or after 24 hours, while the feature line says recoat within 30 minutes. The application data is used on this page.
