Duratec Hi-Gloss Additive for Gelcoats

Add a high gloss to your Gelcoat

Duratec Hi-Gloss Additive is added to gelcoat in a 3:1 or even a 2:1 mix ratio. MEK-P Catalyst is still used and is recommended for the gelcoat at a 2% mix ratio. The Duratec can change the look of your gelcoat project into a paint project with little effort.

Duratec is also great for thinning your gelcoat to allow it to be sprayed without damaging the gelcoat or the color.

Temperature should be at least 64 degrees, with lower temperatures requiring longer cure times.

Mix Duratec in a 3:1 ratio (75% gelcoat, 25% Duratec) all the way up to a 1:1 ratio, depending on desired gloss.

Catalyze at 2% mix ratio with MEK-P 925

Spray over the repair or the surface at around 8 mils per pass, building up to 12-15 mils before allowing to set for 30 minutes before adding another 12-15 mils.

Allow to cure for 24 hours before sanding or buffing for best results.


This product should not be mixed with Sanding Aid or Wax.

    “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.”

    “Been working on a skiff project and using all FGCI products. They came highly recommended by my friends who are boat builders. It is the highest quality resins, glass, and gelcoat for the money. They made it really easy for a newer person to boat building. The customer service is phenomenal and they are always knowledgeable and ready to help with any questions I had.”
