APPLICATION / PREP STEP

(1) For heavily rusted surfaces, prior to wire brushing or scraping, dissolve Prep Step powder in hot water in these recommended amounts and spray with a spray bottle or garden-type pump sprayer-

24 ounces Prep Step dissolved in 1.5 gallons preferably hot water

6 ounces Prep Step dissolved in 0.5 gallons preferably hot water

4 ounces Prep Step dissolved in 1.5 quarts preferably hot water

Wire brush or scrape surface to remove loose scale, then rinse thoroughly with plain water to remove the loosened rust and any other contaminants. Follow step #2 below before painting surface.

(2) For conditioning clean metal surfaces (prior to painting) dissolve 6 ounces of Prep Step in 3.5 gallons of preferably hot water and spray on clean surface with spray bottle or garden-type pump sprayer. Let Prep Step solution dry thoroughly on metal surface before painting – DO NOT rinse with plain water. (NOTE – this step will prevent flash rust from forming on metal surface for up to 30 days, depending on temperature and humidity conditions, so immediate painting is not necessary.

(3) For power washing, dissolve 24 ounces of Prep Step in 10 gallons of preferably hot water and spray at 3000 to 4000 psi.
