After shaking/stirring primer, thoroughly mix four parts 2K Urethane Primer Sur- facer 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).
