Step 1

The ideal working temperature is around 77°F.

Best results can be obtained at temperatures between 70°F and 85°F, in a clean, dry, dust-free environment.

Step 2

Measure product in accordance to the B-sides associated mix ratio:

  • 2700 – 3:1 by volume or 100:28 by weight

Step 3

The material must be mixed thoroughly for at least 3 minutes.

Use a drill mixer or a stir stick to thoroughly scrape the sides and bottom of the cup as you mix.

Step 4

Apply the material liberally by pouring, then work the epoxy into fiberglass with a paintbrush or roller.

Gel Time at 77°F is around 25 to 30 mins at room temperature in a 1/2 pound mass (0.5 pt)

Cleaning Uncured Epoxy

Tools can be cleaned with Acetone, Denatured Alcohol, or Isopropyl Alcohol.

Use small bucket of solvent to clean tools.

Immediate clean up will provide the best results.

    “I love fiberglass coatings. They have great products and excellent advice. I'm trying to open a boat repair shop in St . Mary's, GA and my supply WILL come from fiberglass coatings. When I lived in the Fl. Keys for 36 years and worked for a towing and salvage Co for 15 years all our supplies came from Fiberglass coatings. Great service and never were disappointed. Keep up the great job everyone.”
