1. Application area temperature should be between 70 and 85 degrees Fahrenheit.
2. Mix well before using. DO NOT SHAKE…STIR ONLY Make sure any solids that might have settled to the bottom are mixed back into suspension.
3. Thin by adding 10% distilled water (by weight). SS EkoPrime Primer/Sealer may be sprayed right out of the bottle for heavy build up to fill scratches.
4. Always pour mixed and thinned primer through a medium paint filter before spraying.


1. The first coat of SS Waterborne Primer/Sealer is applied as a light tack coat. Allow to dry untill tacky.
2. Apply 2nd coat to achieve solid coverage.
3. If top coating is desired, allow to dry. Lightly sand with 320 grit open coat sandpaper or ScotchBrite with red ScotchBrite pad.


For best results we advise spraying. But, if brushing or rolling is desired, you can achieve a nice finish with a foam brush or roller. Do not thin the primer with additional water unless it will not flow out.


Clean equipment immediately with water.
