Gelcoats are defined by the base unsaturated polyester resins. We offer several different grades of Gelcoats specifically based on Ortho, ISO and NPG resin systems. The relative percentages of these resins in the Gelcoat determines the final properties of the product, such as:

- Weatherability
- Color stability
- Water/Osmosis resistance
- Durability
- Chemical resistance
- UV light stability
- Ease of application

Directions for use:
Step 1: The application site should be wiped clean of contaminants such as dust and debris. If coating a mold, the mold must be waxed, buffed, and prepped prior to catalyzing the Gelcoat.
Step 2: Gelcoat must be stirred/agitated, preferably with use of a mechanical agitator. Be careful not to whip air into the Gelcoat.
Step 3: We recommend a catalyst loading of 1.5 to 2% MEKP with a working surface and Gelcoat temperature of about 77°F. Please refer to Catalyst Concentration Chart for quantities. Mix thoroughly.
Step 4: For best results, Gelcoat should be sprayed on to the application surface or mold at about 25 mils (measured using depth gauge) in order to achieve a final optimum cured Gelcoat thickness of 18 to 22 mils.
Step 5: For out of mold applications, a second coat can be applied prior to complete cure of the initial coat, unless Gelcoat contains wax.
Step 6: The coating should be cured before sanding and buffing. Allowing to cure overnight is preferred.
Step 7: Refer to Additive Chart for quantities of sanding aid for use in final coat / post mold / out of mold applications.
