HIGH BUILD
High Build Epoxy Primer is an epoxy surfacing primer, used where high build and filling is required above the waterline. Ideal for use over Awlgrip primers and fairing compounds, can also be applied directly to pre-prepared wood or fiberglass.
Conventional or airless spray only. Pressure feed equipment is required.
Surface Preparation Best when used as a surfacer over other Awlgrip primers and fairing compounds. May be applied directly to properly prepared wood or fiberglas, however best results are obtained when these surfaces are first sealed with 545 Primer. Gelcoat/Fiberglass sand with 100-150 grit paper. Wood: Smooth sand with 80-100 grit paper.
Mixing and Reduction Mix by volume one part base with one part converter to a smooth homogenous mixture.
Induction time after mixing: 15 minutes.
Reduce 10-20% with appropriate reducer.
Anticipated Pot Life time at 77 F/50 relative humidity is 8 hours. Higher temperatures may shorten pot life.
Application Instructions
Spray: Apply Awl-Grip High Build Epoxy Primer in even coats of 8 to 10 mils (200-250 microns) wet film thickness yielding 4 - 5 mils (100 to 125 microns) DFT. Two to three coats may be needed.
Note: Do not apply to surfaces warmer than 105 F or colder than 55 F. Do not attempt to cure products at temperatures below 55 F. Do not apply to surfaces less than 3 C or 5 F above Dew Point or to surfaces warmer than 41 C/105 F. Ambient temperatures should be 13 C/55 F - 41 C/105 F.
