309 Gelcoat Plus (Cures Tack Free)

  • 309 GELCOAT PLUS is an “air dry” gelcoat used for re-gelcoating, refinishing or as a finish coating over a polyester or vinylester fiberglass laminate.
  • Can be sprayed, brushed, or rolled onto a sanded gelcoat or a sanded primed surface (use Duratec Primer).
  • When a smooth gloss finish is required, spraying is the best application method. Use a siphon spray or HVLP spray gun with a larger tip, suitable for primer.
  • To spray, catalyze and thin 15-30% with acetone and strain before loading the spray gun. Use Preval Sprayer (pg.21) for gelcoat patching
  • Spray thin coats (2-3 mils) and allow acetone to evaporate for 1-2 min. before applying the next wet coat to that area.
  • Continue to apply wet coats until a wet film thickness of approximately 20 mils is achieved. Then let cure to a mat finish that usually has an orange peel texture.
  • The gelcoat then can be wet sanded and buffed to a gloss finish. Start with 400 or 600 grit on a rubber sanding block and progressively to finer grits, finish with a wool buffing pad and 3M Super Duty Buffing Compound.
