Notes:

1. Do not forget to add plus minus 10% wastage when calculating the area of the pool.
2. For 600gsm of chopped strand mat use the 300g table and multiply the glass and resin volume only by 2 , as there are 2 layers of 300gsm each.
3. Catalyst is calculated at 2% of resin weight. Minimum of 1% and a Maximum of 3% depending on the temperatures is added to the resin and top coats.
4. Resin required per square meter of fibreglass:
Fibreglass 300gsm = 750g of resin.
Fibreglass 450gsm = 1.13kg of resin.

PLEASE NOTE:

Where catalyst weights become critical is that vol% is slightly more than weight %.
i.e. S.G. of catalyst = 1.16

Therefore:
vol% x 1.16 = mass %
1.5% x 1.16 = 1.74%
2.0% x 1.16 = 2.32%

Therefore for large weights such as 25kg rather use 1.5% than 2%


Quantities used per product:
Ideally Gelcoat is applied between 500 to 700 g/m²
Resin to Fibreglass ratio: 2.5kg of resin to 1 kg of fibreglass.
