Key specifications

Choosing the right option

Conventional enamels should not be used over zinc rich primers unless a barrier coat such as Etch Primer is first applied over the Zinc It coating; see CRC Etch It Etch Primer for White & Yellow Metals 2110 - 400ml. For a zinc rich paint that dries bright silver see CRC Aerosol Bright Zinc Galvanic Rust Protection 350g.

Using it

Thorough surface preparation gives longer protection. Ideally use abrasive blasting to AS 1627.9 Class 2, which substantially removes millscale, rust and foreign particles so that grey metal is visible. Apply to a firm, dry, thoroughly abraded surface.

Shake the aerosol thoroughly to mix before use. Correctly mixed, it is smooth and uniform throughout and dries a flat mid grey.

Overpainting: conventional enamels should not be used over zinc rich primers unless a barrier coat such as Etch Primer is first applied over the Zinc It coating.

For clean-up after spraying, use thinners.

At 20 °C it is touch dry in 20 minutes, recoatable in 8 hours and hard in 24 hours.

Storage and handling

Do not puncture, incinerate or store above 50 °C. Do not place in direct sunlight or near any heat source. It has a conditional warranty of 5 years from the date of manufacture.
