Mixing Instructions:
The gelcoat you are buying is an Isophthalic, NPG gelcoat with wax additive for an air dry post applied application. Mixing instruction depends on the temperature and preferable dry times. The higher percentage of catalyst the faster it will dry. Air and surface temperature will also affect the drying of the gelcoat. The colder the air temperature, the higher the percentage of catalyst you should use. Do not go below 1/2% or above 2%.

Tips

1 mL = 1 cc

If using wood mixing stick, place stick in resin before adding catalyst so wood doesn't absorb catalyst
