About Eastwood 4:1 Tan Urethane Primer and Activator Kit

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

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).

HVLP Gun: Fluid Tip 1.4-1.6 mm Spray Pressure 25-30 psi
Conventional Gravity: Fluid Tip 1.4-1.6 mm Spray Pressure 40-50 psi
Conventional Siphon: Fluid Tip: 1.4-1.8 mm Spray Pressure 40-50 psi

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.
