Product Overview:

Description

Eastwood Urethane primer is a two-component surfacer designed for overall jobs.

  • Mixes 4:1 with 50241ZP Activator
  • Fills well and builds quickly
  • Dries fast and easy to sand
  • Apply over epoxy primer, body filler, existing finishes
  • Made in the USA

It fills well, sands easily and provides excellent color holdout for all top coats. Mixes 4:1 with 50241 ZP catalyst. May be applied over Eastwood Epoxy primers, old paint, body filler & even bare metal. Ideal for block sanding in 3-4 hrs after application. When primer is mixed 4:1 with activator it makes 5 spray-able quarts. Primer is VOC 4.8 lbs per gallon.

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).

SPRAY GUN SETUP when used as a HIGH BUILD PRIMER SURFACER
HVLP Gun Fluid Tip 1.5-1.7 mm Spray Pressure 8-10 psi at Air Cap (25-30 psi at regulator before gun)

APPLICATION INSTRUCTIONS
Eastwood 2K Urethane Primer Surfacer should be applied in two medium wet coats, with a 10-15 minute flash period between each (at 70 °F). Typically, two coats is enough to achieve the desired 2 mil. dry film thickness, though more material may be applied as needed.

Urethane Primer Surfacer may be topcoated after approximately 30 minutes, or up to 18 hours (at 70 °F with sufficient cross-ventilation), with no additional prep required. After 18 hour recoat window, primer MUST be sanded prior to topcoat application for adhesion purposes.

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

Rated 5 out of 5 by from Great Primer Great Product. Dries quickly and works very well for a primer. It make the finished product look more smooth than other primer products we've tried. The extra expense is more than off set by the time we save waiting for it to dry to sand in comparison to other products.

Rated 5 out of 5 by from 5 Stars Absolutely love this product. Will be using on all future projects as well.

Rated 5 out of 5 by from Great primer I have used the black 2k as a final primer for several years now in my restoration shop. It sprays, and fills well and sands pretty easy. Also after 400 you can wet it down and easily check your panel for imperfections.

Questions & Answers

Can this primer/surfacer be used on ‘70’s polyurethane bumpers? Does a flex agent need to be added?

Asked by: Trashcan78
Technically yes, but it is likely to crack when the bumper flexes. A MUCH better option would be a flexible primer such as this here: https://www.eastwood.com/sem-flexible-primer-surfacer-aerosol-gray.html

Is this product compatible with other products with no worry of a reaction to other brands of automotive top coats?

Asked by: Tim 67
We can not guarantee compatibility between our products and products/brands we do not sell. Every brand uses different solvents and resins at different percentages. When you mix/apply one over another there is always a chance a negative reaction can occur.

Do I wet sand after application or dry sand and what grit do you recommend

Asked by: Kaleb
Dry sanding would be ideal. We recommend finishing with 400 if then applying a solid color and 600 grit of applying a metallic/pearl.

Can this product be used as a sealer?

Technically, yes. It needs to be mixed 4:1 with the catalyst then reduced by 20% with any of our Urethane reducers.

Will this stuff seal against moisture? I plan to put this on and I’m going to wait to paint when I have the money.

Asked by: Luke
Urethane primer will not seal off against moisture. It will absorb moisture if exposed to it. Epoxy primer will seal off from moisture though.
