5 Tips on Various Fiberglass Coatings Solvents

1. Acetone is good for cleaning polyesters, but not epoxies.


2. Lacquer Thinner tends to be a good solvent for cleaning surfaces to remove wax and oils.


3. Isopropyl Alcohol 99% (water free) is a mild solvent that is recommended when using Epoxy Table Top Resin and cleaning new epoxy surfaces.


4. Mineral Spirits works well with paint and polyurethane enamel.


5. Styrene reduces polyester, iso and vinyl ester resins for better wood penetration.


4 Tips on Boatyard Polyester Resin

1. Boatyard Polyester Resin may or may not contain wax. If it contains wax, laminates will dry tack-free. If it does not contain wax, the surface will have a tacky feel unless sanding aid is added to the final coat.

2. This is an economical laminating resin for repairs on boats (not recommended for use below the waterline), autos, etc.

3. This a non-spec resin. It is a mix of different types of polyester resins, according to what is manufactured that day. Boatyard resin contains varying ratios of orthopthalic, isophthalic, and low profile resins and should be sanded between cured laminations to enhance the bond.

4. The ideal temperature is at 77°F. Best results for this product can be obtained at temperatures between 70°F and 85°F, in a clean, dry, dust-free environment.

5 Tips for Using Vinylester Resin

Vinylester-Resin-Kit1. Vinylester Resin requires 2% MEK-P every time it is used in order to cure properly.
2. The maximum heat temperature is 220°F.
3. This product can be used to help gelcoat bond with epoxy.
4. The ideal temperature is at 77°F. Best results for this product can be obtained at temperatures between 70°F and 85°F, in a clean, dry, dust-free environment.
5. Do not go over 1/8” in thickness. More than 1/8” in thickness will generate too much heat.

5 Tips for Liquid Urethane Foam

Liquid-Urethane-Foam-Set-Ju1. 2 quarts of 2 lb. foam will cover 2 cubic ft.
2. 2 quarts of 4 lb. foam will cover 1 cubic ft.
3. 2 quarts of 8 lb. foam will cover 1/2 cubic ft.
4. The 2 lb. foam expands the most, with the 4 lb. & 8 lb. foam expanding progressively less.
5. Once the foam hardens, the only way to remove it will be to sand or grind it.

5 Tips for Using Gelcoat

Gelcoat Photo1. When spraying gelcoat, we recommend using spray guns with 2.0 nozzles or bigger.
2. We recommend chilling the gelcoat down to 70°F to prolong the working time.
3. Before using gelcoat, it must be stirred/agitated. The use of a mechanical agitator is preferred. Do not whip air into the gelcoat.
4. Gelcoat is suited for a broad range of high quality, open-mold, lay-up applications including boats/yachts, swimming pools, sanitary ware, sinks, recreational vehicles, commercial/mass transit vehicles and industrial components.
5. Apply in smooth brush strokes yielding a wet film thickness of 18-20 mils. Gelcoat can be brushed, poured, rolled or sprayed .
