What is the mixing ratio for fiberglass resin?
A 2 oz. tube of liquid hardener (MEK Peroxide) is sufficient to harden the entire contents of a gallon container. Add 14 drops of liquid hardener per 1 oz. of Fiberglass Resin (or for ¼ can of Fiberglass Resin, use ¼ tube of liquid hardener).
How do you calculate resin for fiberglass?
General Formula for coverage of Epoxy resin to fiberglass cloth. A general formula is to plan a ratio of 1:2.5 resin. This means for every ounce of cloth, you use 2.5 ounces of resin in a total of about 3 coats.
How much resin do I need for fibreglass?
The ratio of resin : fibreglass is approximately 2.5 : 1 i.e 1 kg of fibreglass requires approx. 2.5kgs of resin.
How much hardener do you use with fiberglass resin?
For small applications use 10 drops of hardener per ounce of resin. Working time will be 10 to 12 minutes. For larger applications, use half of the fiberglass resin hardener supplied, to half of the resin container.
Will fiberglass resin harden without enough hardener?
You let it sit, and sit, and sit, but it never completely hardens. Chances are you did not add enough catalyst, the chemical that hardens the resin. It’s a chemical process and depends on how close you were to the proper amount of catalyst.
How do you mix fiberglass resin jelly?
Mixing: Knead cream hardener tube thoroughly. For a golf ball-size amount of resin jelly, squeeze out 1 1/4 inch strip of hardener, or mix a 3 inch diameter circle 1/2 inch thick of resin jelly to a 3 inch strip of cream hardener. Mix thoroughly to a uniform color on clean, non-porous surface.
What is the ratio of resin?
Mix the resin VOLUME – To achieve the correct 2:1 mix ratio by volume, simply measure out 2-parts resin to 1 part hardener before mixing the components. WEIGHT – The exact weight measurement for these ratios is slightly different from the volume ratio due to resin and hardener density.
How do you calculate gelcoat?
When looking at the thickness, gelcoat is recommended to be about 15 mils thick, or roughly the thickness of a credit card. You can apply up to about 20 mils, but anything thicker can result in cracking. Once you know your thickness, at 15 mils, you will get about 25 square feet per quart or 100 square feet per gallon.
How do you calculate resin ratio?
Resin Weight = (resin ratio / (resin ratio + hardner ratio)) x desired weight. Hardner Weight = (hardner ratio / (resin ratio + hardner ratio)) x desired weight….
| For a ratio of: 10:1 | ||
|---|---|---|
| Total weight of epoxy | Weight of resin | Weight of hardner |
| 106 | 96.4 | 9.6 |
| 108 | 98.2 | 9.8 |
| 110 | 100 | 10 |
What do you do when fiberglass resin won’t Harden?
How do I Cure Fiberglass Resin That Doen’t Have Enough Hardener…
- Set the fiberglass in the sun. The curing of fiberglass resin is an exothermic reaction, meaning that heat makes it work.
- Use a heat gun on the fiberglass.
- Spray a mist of catalyst onto the fiberglass with a spray bottle.

Can fiberglass resin go bad?
There are few things worse than having finished a large project using fiberglass, only to not have it fully cure. You let it sit, and sit, and sit, but it never completely hardens. Chances are you did not add enough catalyst, the chemical that hardens the resin.
What removes fiberglass resin?
– Use a more powerful heat gun. – Work more slowly. – Remove the glass on a slight angle to the grain direction of the wood to reduce wood peel or pull from the opposite direction. – In stubborn areas, force a thin dull putty knife under fiberglass that has been softened with heat.
