High Quality Fiberglass Gelcoat

We offer 2 variations of our high quality gelcoat. Brushable and Our Original Exterior Gel Coat both have their purpose. Our Brushable Gel Coat is fantastic for spot repair and small projects like hatches, saving you time by skipping the spraying process. Our Original Exterior Gel Coat is perfect for large applications such as a complete re-gelcoating of a boat, or for in mold manufacturing applications. Exterior can be used inside the boat as well as above and below the waterline. 

Certified for Food Grade Use

Additionally, our gelcoats are certifiable for food grade use. All certifications have to be done by the end user. 

 

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! 

FGCI’s 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 determine the final properties of the product. Such as:

– Weatherability

– Color Stability

– Water/Osmosis Resistance

– Durability

– Chemical Resistance

– UV Light Stability

– Ease of Application

FGCI’s high level ISO/NPG resin based Gelcoat, composed of the highest quality pigments, will provide the best combination of the above mentioned properties.

FGCI’s Gelcoat and Brushable Gelcoat are very well suited for a broad range of high quality, open mold, lay-up applications. This includes:

– Marine Applications

– Swimming Pools

– Sanitary Wares and Sinks

– RV’s, Commercial/Mass Transit Vehicles

– Industrial Components

 

Brushable Gelcoat 

Brushable Gelcoat is formulated to be applied like paint and eliminates the need of spray equipment.

A second coat may be required to achieve full hide/coverage when applying to darker surfaces. Excessive brushing may cause pinholes.

Gelcoat Instructions

 

Original Exterior Gelcoat Instructions

 

Materials Needed:

 

  1. Mix & Measure Buckets
  2. Gloves
  3. CC Cups
  4. MEKP
  5. Mixing Sticks
  6. Spray Gun
  7. Depth Gauge
  8. Sanding Aid (not for use in a mold)

 

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 2.5% MEKP with a working surface and Gelcoat

temperature of about 77° F. Please refer to the Catalyst Concentration Chart for quantities. Mix Thoroughly.

 

Step 4:

For best results, Gelcoat should be sprayed on to the application substrate 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: 

A second coat can be applied prior to completing the cure of the initial coat, unless the Gelcoat contains Wax.

 

Step 6: 

The coating should be cured before sanding and buffing. Allowing it to cure overnight is preferred.

 

Step 7: 

Refer to additive chart for quantities of SandingAid for use in final coat/post mold/out of mold applications.

 

Clean Up Procedure:

 

Cleaning FGCI Gelcoat: Use Acetone to clean spray equipment, brushes, and rollers. A small bucket of solvent can be used to clean tools and spray nozzles.

    “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.”
