MIXING DIRECTIONS

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.

SPRAY APPLICATION

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.

BRUSHING & ROLLING

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 UP

Clean equipment immediately with water.

I used Stewarts system before on another airplane, it is water based so not toxic and or cancer causing . It works good, easier to use and not requiring a breathing device just a mask. I have not shoot this color of paint but we shall see. Again like with the cylinders I bought a few weeks ago in 10 years I will be able to tell you how good this material is, well see how long it lasts.

I have used this primer for about 4 years and had good results, even when the primer was well past the claimed shelf life.

As an experiment I tried using a foam roller and than a brush to apply this primer.. according to the on can instructions you shouldnt have to thin it. without thinning it did not flow and the foam roller caused a lot of bubbles that left a texture when dried that took a lot of sanding to get out. After adding distilled water and using a good brush i got better results. However spraying is by far the preferred method. It produces a nice hard but easily sand-able surface

I love the Stewart system. We have covered 2 wings and the products are great.

This primer may not be quite as tough as epoxy primer, but its other properties more than make up for it. It's easy to spray with no need for extensive protective gear and no solvent fumes. Whatever you don't spray can be poured back into the can - try that with Akzo. My only very minor gripe is that it's fairly easy to knock off of sharper corners, but I think it's a problem with any primer.
