Description

Eastwood Gray Urethane Automotive Primer and Activator

Get ready for the final coat on new parts or autobody repairs with this gray 2K primer and activator combination. High-build urethane primer is a versatile surfacer that can be applied over bare metal, body filler, epoxy primer, existing paint and much more. Since the primer is sandable and fills imperfections as you spray, it’s great if you want to get an older surface perfectly smooth. The activator promotes adhesion for the primer and also helps it dry faster so you can get to painting.

Our 2-component gray automotive primer kit is an ideal all-around solution if you’re repainting an entire restored vehicle or running a professional shop. It’s made in the USA with excellent color holdout at temperatures up to 150 degrees A gallon of primer mixes 4:1 with the activator to create five sprayable quarts, which covers 140 square feet — more than enough for the average car or small truck. Eastwood provides lifetime tech support by phone or email to help you Do the Job Right.

Specifications

MIXING RATIO

After shaking/stirring primer, thoroughly mix four parts 2K Urethane Primer Sur - facer with one part Urethane Primer Activator

Option

To reduce film build, 4:1 mixture may be cut by up to 20% with a urethane-grade reducer or other appropriate solvent product. Doing this may also improve the flow and leveling of primer. Eastwood suggests using a Zero-VOC reducer to avoid potential compliance issues. Use caution in mixing materials as epoxy primer may begin to gel after approximately two hours (at 70 °F).

I'll be using epoxy primer 1st, then this urethane primer, my question is can I spray acrylic enamel over this ? I was going to have my factory color mixed at napa

Asked by: Kenny
Unfortunately we can not guarantee compatibility between our products and products/ brands we do not sell. Our paints are Acrylic Urethane based and this is all we test with. If you still wish to try this then we have to recommend trying on a scrap piece of metal first or a small inconspicuous area before applying liberally to the surface.

Can I spray PPG base color over the Eastwood high build primer?

Asked by: Car42jam
Unfortunately, we can not guarantee compatibility between our products and products we do not sell; since it has not been tested. We would have to advise you to test on a scrap piece of metal first or on a small inconspicuous area before applying liberally over everything.

The instructions say 25-30 psi “spray pressure”. Normally a “at the tip” pressure is given. Could you be more specific in your directions?  Is 25-30 an at the tip pressure?  Seems high…

Asked by: Timm
25-30 PSI is the pressure the regulator attached to the bottom of the paint gun. This should yield about 8-10psi exiting the air cap.

An answer to a previous question is that this urethane primer can be sprayed over fiberglass. Would a sealer then be recommend over this primer?

Asked by: chpjr
Yes, this can be used on fiberglass surfaces. A sealer is only required if you plan on leaving this primer exposed to moisture or humidity before you get around to sealing it off with your top coat. If this is needed we recommend using our Epoxy primer (mixed 1:1 with its catalyst) and then reducer by 20% with Urethane reducer.
