Can anybody help me with estimating the amount of epoxy resin needed in my boat building project?<br />I will use 6 oz fiberglass cloth. Is there a per square foot coefficient I could use in estimating? I'm ready to order and don't know how much I'll need.<br />Thanks,<br />otterbfishin

Re: HELP How TO Estimate Quantity of Epoxy Resin

if you buy it from a good place (like uscomposites.com), they will tell you exactly how much you need. i know cloth is measured in oz. per square yard, and I know at least with mat and woven roving, you order at least 1 oz. of resin for every one oz. of material. i assume it's the same with cloth (only done small jobs with cloth for custom audio parts for cars, and i never measured how much it needs).<br /><br />but figure out how many square yards of cloth you have, multiply that number by 6, and that should be the number of ounces of resin you need (and just convert that to gallons/quarts).<br /><br />since i haven't done large cloth jobs, wait for someone else to back me up on this.

Glass is glass. 1 oz of resin per 1 oz of cloth for estimating...measure in sq ft or sq yd.

1:1 is the proper ratio for use as BillP says, but you may want to double up on the resin purchase as you are sure to waste much of what resin you start with. ;)

Any way to estimate epoxy for saturating and sealing okume plywood. Not the fiberglass side, but all of the inside surfaces?<br />Thanks
