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).

May be wet sanded after 2-3 hours, or block sanded (dry) after 3-4 hours.

Customer Reviews

Rated 5 out of 5 by from Best product Lays down perfectly. High build. Easy to work with. Sanded down with a guide coat in minutes. Wet sandable in 2 hours

Rated 4 out of 5 by from Thick Primer Really like how it builds up thick to level parts. Hate spraying it speaking for me though. You have to use larger nozzle cause it's thicker which drains my air compressor fast. So you either wait for air or keep spraying and the surface which turns out rougher and smaller fan. Easy mixing.

Rated 4 out of 5 by from Thick Very thick make sure you have a larger tip. I sprayed with a 1.7 tip and had to add reducer so I did a 4-1-1 ratio and it sprayed ok then.

can urethane primer be thinned out to be used as a sealer? if so can it be tinted? what is suggested to tint it with?

Asked by: yeah dawg
Yes, this can be. You would mix this at the 4:1 ratio it calls with the catalyst/activator then reduce that by 20% with any of our Urethane reducers. This can not be tinted or mixed with anything other than more of our same 4:1 Urethane primer.

After dry or wet sanding. To clean the surface for base. Do I use a pre paint cleaner or just water and a rag? 

Asked by: Christopher
You can spray the PRE onto the rag and then wipe to clean. You just do not want to saturate the surface in any way.

I plan to repaint a plastic front bumper that has a lot of stone chips. Is this the right product to prime with after sanding?  Will this adhere to the plastic bumper without adhesion promoter?  What should I use to fill the stone chips?  

Asked by: Randy
I would watch YouTube videos of paradise auto body.  Eastwood has gotten terrible with helping others on projects

When I put down 2 coats of epoxy wait 45min and put 2 coats of the urethane. How long do I have to wait to throw down the base and clear coats? Is it true also the urethane will shrink if I don’t wait long enough? Thank you 

Asked by: Chris
We state the Urethane can be top coated as soon as 30 minutes. Personally I would recommend waiting a minimum of an hour after applying to avoid shrinkage.

I have my car primed in this. I plan on spraying base coat clear coat. What sanding progression do you recommend?

Asked by: Tt48
You will want to start your sanding at 320 grit and then work up to 400-600 grit depending on the type of paint you are top coating with.

After spraying on my epoxy primer.  How long after do I have to wait before I can start separating the urethane primer. Over it. And can I spray epoxy or urethane primer over areas where rust encapsolator platinum was put on. 

Asked by: Chris
Yes you can spray over Platinum Rust Encapsulator. Do not understand separating urethane primer? If applying two or more coats of epoxy primer, you should wait 45 minutes to one hour before top coating or applying urethane primer.
