reinforcing the hull

[ranger42]

hello every one.im in the middle of replacing stringers and transom in my 15ft bowrider blazer iv noticed a crack under one stringer that goes all the way thru and a chisel hole i made while taking out the old stringers. anyways the bottom seems thin to me. im thinking about laying a sheet of fiberglass cloth over the entire bottom. what weight of cloth should be used to do this.

Re: renforcing the hull

how would this work Quadaxial Fiberglass Cloth 37 oz

That would work, just make sure the old glass is sanded down to good fresh glass and wiped down with acetone to promote a good bond with the new.

i wanted to be prepared for the sanding i went to day bought resperator a suit and mask goggles and gloves. can i use the polyestor type of epoxy like the stuff that autozone sells for boat repairs

Re: renforcing the hull

You could but I would not. It is not for marine use, it's expensive and you will need approx. 5 gals or more just for the hull reinforcement not counting the rest of the glassing you will be doing. You need a good quality Laminating Un-waxed Polyester Resin U.S. Composites, Inc. - Fiberglass , Epoxy , Composites, Carbon Fiber is a good online source.

Re: renforcing the hull

so i need to use 5 gallons epoxy to lay 5ft by 13ft of 37 oz mat

Re: renforcing the hull

Epoxy and polyester are very different types of resin, so you need to pick one or the other. There are differences in how they are used, so any answers will be specific to the one you choose.

37 oz fabric is very heavy, it may not be what you want to use.

Re: renforcing the hull

i orderd 24 ounce cloth to. would this work better. im thinking on going with polyester resin due to cost. and i have 1 gallon allready. im going tomorrow. buying 4 more. and i wasnt thinking. but it needs more than one coat doesnt it

Re: renforcing the hull

Mat and cloth are also different products, and 24oz wouldn't refer to either of them. I'm not trying to hassle you over the terms, only that it makes a difference in how the questions are answered. It will be a little difficult at first, but you will catch on quickly. Read a few other threads and you'll get a good idea of the terms, there are stickies at the top of the page with a great deal of info also.

Hi ranger42,
What "ondarvr" is talking about is the TON of information that is located here...http://forums.iboats.com/boat-resto...r/how-tos-other-great-information-288451.html

Lots of good info...

Also noticed that you said you already had a gallon of resin...Is it laminating/lay-up resin, or some general purpose resin?
Where did you get it at?
The reason I am asking is because there are types of resin that contain a wax additive in them.
You don't want to use these...

L8r,

I'm sorry if you feel you need to go elsewhere, but for accurate answers we need to know exactly which products you plan to use and what you have on hand. If the names and terms used are not correct, or are changing, we can't be sure of the exact products you are asking about.

Re: renforcing the hull

ok here is what im going to use. Bondo? Fiberglass Resin is the same high-strength polyester resin that is used to build most boats. It can be used alone or with fiberglass tape, cloth or mat to repair damaged fiberglass boats, snowmobiles, jet skis, bathtubs and showers. It can also be used as a sealer on damaged and rotted wood, it seals concrete, is great on large or small metal rust-outs and joins most surfaces together while creating a strong and long lasting bond.

Sandable in less than 2 hours
Compatible with all paints, including gel coat and marine paints
it doesnt say anything about containg wax
