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 to a bright silver similar to new galvanised iron.

For clean-up after spraying, use enamel thinners.

At 20 °C it is touch dry in 20 minutes, recoatable anytime 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.
