47ft Cat - How Much Laminating Resin?

[Beluga]

I am estimating how much laminating resin (MAS Epoxies) I need to cover:
1. 1,216 sq. yds of 24 OZ BI AX WR
2. 2,958 sq. yds of 1 1/2 oz mat

This is a calculation I am incorporating into my estimate of materials cost of a 47ft Cat.

My original calculation came out way too high (1,278 gallons). I am not sure I am doing it right. If you need more info or are interested about the project I could share more details, just ask.

Regards,
Carlos

I would ask two different resin companies, and take the larger number!

You should be buying by the drum. Check with your supplier that excess unused resin can be returned. Wouldn't want to run out just before the end on a long weekend.

The same goes for cloth...

There were some estimated resin requirements here for the mat: Fiberglass Mat

Based on those, you need about 450-500 gal of resin for the mat alone.

You know the total weight of your BI-ax and mat
You know the weight of your resin per gallon
You know what glass- to -resin ratio you have to attain for the required strength
With those numbers you can approximate your resin weight, converted to gallons
Back in the 70's, in the polyester days, I think we used to lay-up 70% glass-30%resin. Lost a few brain cells to those VOCs, so don't use those figures
