Asked by: Rebecca Vigil
Fiberglass chopped strand mat (CSM) is rated in ounces per square foot and requires 2 times its weight in resin for adequate wet out. 1.5 oz. CSM will need 3 oz. of resin per square foot of mat.
How do I calculate how much resin I need?
For a round surface, you will need to measure the diameter. Divide the diameter by 2 to calculate the radius. To calculate volume in cubic inches: (radius squared) X pi (or, 3.14159265) x (desired epoxy coating thickness). Divide by 1.805 to convert cubic inch volume to US fluid ounces.
How much fiberglass epoxy do I need?
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.

|---|---|---|
| 1mm | 62.5g | 500g |
| 2mm | 125g | 1kg |
| 3mm | 188g | 1.5kg |
How much hardener do I need for 1 gallon of fiberglass resin?
For best results, bring resin and hardener to room temperature (minimum 65ºF). 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.
How much does 16 oz of resin cover?
about 8 square feet
8 oz. will cover about 4 square feet, 16 oz. will cover about 8 square feet. 32 oz. will cover about 16 square feet, and 2 gallons will cover about 128 square feet. You can use a brush to spread the resin thinner for lighter coats.
How much fiberglass resin do I need per square foot?
Fiberglass chopped strand mat (CSM) is rated in ounces per square foot and requires 2 times its weight in resin for adequate wet out. 1.5 oz. CSM will need 3 oz. of resin per square foot of mat.
How much resin and hardener do I mix?
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 much hardener do I need for 8 oz 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.
How many drops of catalyst do I need for resin?
a. Fibreglass Resin: for 100ml of resin (cold day) use 2.5 to 3ml catalyst; and for 100ml resin (hot day) use 1.5 to 2ml catalyst. 3. Use a measuring cup for the amount of catalyst needed or if using the dropper bottle 1ml = 50 drops.
What happens if you put too much catalyst in resin?
Adding too much of either resin or hardener will alter the chemical reaction and the mixture will not cure properly.
What is the ratio of catalyst to resin?
The ratio range for catalyst to resin is 1 to 2 percent hardener to the total volume of resin to be used. For example, four drops of hardener will be 1 percent of 1 ounce of resin. Adding more of less of the catalyst agent will speed up or slow down the curing time for the resin.
How much catalyst do I need for 500ml resin?
6. Liquid Catalyst – (MEKP-NA2)
| Resin | Liquid Catalyst – MEKP NA2 (ml) |
|---|---|
| 250 g | 5 ml at 2% |
| 500 g | 10 ml at 2% |
| 1 kg | 20 ml at 2% |
| 1.5 kg | 30 ml at 2% |
What kind of hardener do you use for fiberglass resin?
Bondo fiberglass resin liquid hardener is designed specifically for use with Bondo fiberglass resin and Bondo metal reinforced filler. This hardener is easily mixed with resin or filler; a chemical reaction creates an extremely strong, waterproof repair material.
How do you mix Fibreglass resin and hardener?
It's just a job of mixing. It. Any sort of clean wood or plastic will do as long as it has flat size for a thorough. And complete mix.
Do you add catalyst to top coat?
Topcoat will require catalyst to convert it to a cured coating. Do not forget to add catalyst. Topcoat provides a durable cosmetic finish and works as a UV barrier preventing UV degradation of the laminate. It is essential to apply Topcoat.
How much top coat do I need?
You should always apply one coat of base coat, two coats of polish, and two coats of top coat for an optimal manicure. The key to a salon-like mani is covering your nail in three strokes – any more tends to result in streaky, clumpy nails.
Can you fibreglass in the rain?
Rain interferes with the fibreglass resin and can alter its properties. If it starts to rain, don’t continue working. Instead, stop what you’re doing and cover any resin that you’ve applied with a waterproof sheet.
How much hardener do you add to top coat?
Pour a ratio of 4 to 1. You will be using 4 oz. of clear coat for every 1 oz. of acrylic hardener.
Do you need to add catalyst to resin?
Resin and Topcoat both require catalyst. Topcoat is not paint. It is essential to add the correct quantity of catalyst. Too much catalyst weakens cured resin and topcoat.
What happens when you put too much hardener in automotive paint?
Incorrect mixing ratio: If too much activator/hardener is used, or if the correct ratio is not properly mixed, defects may appear in the finished dried paint film. Environmental conditions: Excessive heat or humidity during application and curing can cause surface imperfections such as cracking.
