Spray, splash or pour Galv-Etch onto surface and spread with non-metal brush/broom/scouring pad. Be careful not to contaminate the solution in the bottle with black oxide formed on applicator.
Leave Galv-Etch on for at least 15min, but no longer than one hour
Rinse with clean water and light abrasion (brush/broom)
Allow to dry for at least one hour before painting. During this time, etching of surface will take place
Preferably paint the same day, as leaving overnight can cause dew to form, resulting in the formation of white mildew (also called white rust) that will need to be washed off with water and a scouring pad before surface can be painted.
Before painting, make sure that the Galv-Etch treated surface is water-break free and contains no loose powder dust.
If there are bright, smooth patches still remaining on the surface, re-apply Galv-Etch over these areas until the entire surface is roughened and ready for painting.
It is important that good painting practices are adhered to, such as same day second coat application. The first coat of paint usually forms microscopic holes as the paint dries and will allow moisture creep if left overnight or if wet weather conditions appear before second coat is painted. The second coat will effectively seal the surface, but if moisture is trapped under the paint, it will result in paint failure.
In coastal conditions the use of water-based paint is recommended, as the second coat can be applied much sooner as can be done with oil based paint, therefore avoiding salt deposit and subsequent salt creep.
When the surface is ready, a minimum of two topcoat layers should be applied. Adhere to good painting practices in order to achieve a longer lasting, flake-free result. Do not paint in damp conditions.
When spray painting or baking, the use of a primer is recommended.
