fiberglass resin

[slickchaos]

hey guys,

im in the process of gathering the material needed to do a foothold install this winter...

Last nite at home depot, i noticed they had 1 gallon of fiberglass resin made by Bondo. Says its can be use for marine and its waterproof.

they also carried the the fiberglass strips and mats, as well as the hardener..

I know most people on here like to order from us composites, but has anyone used this brand before ?

I haven't used it but the cloth is not Biaxial at home depot, at least not in my area.

 

[slickchaos]

what does the biaxial do ? im new to anything fiberglass related..

im assuming its going to be stronger ?

I use the bondo fiberglass and fibers (mats) for all my repairs since it is the most available around here. So far it has been very resistant to shocks and water. I suggest getting an extra hardner bottle. I find that for bottom of hulls and some steep sides the glass is too liquid and more hardner helps laying it out without getting my shoes covered.

The bondo resin is Polyester resin.
I do not recommend you use anything but Epoxy resin.

 

[slickchaos]

thanks for the tip.. im just going to be using it on footholds, rather something under the water line...

ohh.. thanks matt.. i didnt know there was a difference...

It is extremely difficult to find epoxy resin in stores. Most likely, you'll have to order it. (I buy 3 gallons at a time for 158 shipped)

You can work with polyester resin on a Roundnose topdeck, but not on the bottom, and not on top deck of a Square.
I think the hood on a Round is out, too.

 

[slickchaos]

so polyester resin would be ok for footholds as its topdeck ? but you recomend using the epoxy resin instead for strength ?

 

[Matt_E]

It should be, but no guarantees. I have never done it with anything but epoxy resin.

hey slick - you can buy epoxy resin on ebay or at westmarine.com

 

[tor*p*do]

epoxy = good
bondo = bad
do it right the first time or do it again!

 

[slickchaos]

Epoxy it is.. thanks !

Very good resin, great price. Awesome for laminating, comes with pumps, and it cures clear.

The pumps are nice to use!

How much do you need to do footholds and to reinforce the hull?

i was told 1 gallon of resin was enought for footholds and for reinforcing the tray.

 

[ChrisGooch]

you shouldnt have to use any more hardener that what comes in the kit. If you are mixing it in the wrong ratios, you may have issues down the road.

Where are you located in ontario? I know of a few places (spread from downtown toronto to hamilton) that carry epoxy resins, glass, carbon, whatever you want.

Way more than enough.

You could probably do with one quart. I'd get two quarts just in case.
Personally I stick with the quart cans just so I never have too much old stuff sitting around. (Especially the hardener you don't want hanging around for like years)

You can use the home depot/auto store woven glass cloth (bondo brand or whatever) with epoxy. The chopped strand mat has binders in it so you need to watch about compatibility.
