Quantum HB epoxy primer activator is combined with Quantum 45 epoxy primer base (sold separately) to create a high build primer that covers gouges and other surface defects easily and effectively.
There is no need to apply a surfacing primer over it. The high build primer's unique pigment blend lets you apply Quantum 99 topcoat directly over it without compromising gloss levels or smoothness.
Quantum strongly recommends Quantum epoxy primers in order to maximize adhesion and gloss for Quantum 99 polyurethane topcoat.
Available in quart and gallon sizes.
Warning: Do not apply paint materials to surfaces less than 5°F above dew point, or to surfaces warmer than 125°F. Substrate (application surface) temperature should be minimum 45°F to maximum 125°F.
