Pumice Gelcoat Additive


Our FGCI Pumice Gelcoat Additive is a perfect paint or gelcoat additive to create an anti-slip surface. We offer different grain sizes. The smaller grain can be mixed into the gelcoat or paint and sprayed on your desired surface. Our pumice additive will not affect the final color of your paint or gelcoat

With FGCI, you can rest assured that your batch will be within specs every time, with the same color, viscosity, strength and application characteristics as you would expect from a high quality product. After all, we haven’t been in business for over 60 years without ensuring our quality standards are the highest, and accompanied with the best customer service!

Pumice Additive


The instructions for this product are rather straight forward and easy.

Step 1:
Mix and apply your first layer of gelcoat.

Step 2:
Follow gelcoat instructions to build up the proper millage of gelcoat needed.

Before your final coat, and while your previous coat is still tacky, tape off the area you want the non skid. Sprinkle by hand, or by your personal choice of application. Then apply your final coat of Gelcoat with the Sanding Aid Wax Additive. You will end up with a shiny, non skid surface!

    “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.”
