need to lay some galss on a flat deck on my boat? what weight and style should i use…
Thanks in advance.
ft worry.
Really will depend on what purpose the glass will be for and what it is going over, wood or old glass, to reinforce, build up, patch a crack, etc… Fiberglass mat has little fibers running everywhich a way “glued” together. Fiberglass cloth is long strands woven together bi directionally. Mat is normally used to prevent the “print thru” to the gel coat of the cloth and in areas not requiring a lot of strength, it will conform to odd shapes pretty easy and will build up thickness pretty easy. It comes in weights from about .05 ounce(light) up to about 3 ounce(heavy) Fiberglass cloth gives superior stength but will not form over odd shapes as easy. It comes in weights from about 4 to 20 ounce. Woven roving is even heavier up to about 40 ounce.

just goin over a flat wood deck that im puttin on my high tide. took the top shell off. no crazy shaping or anything… i was lookin at the biaxial type cloth. around the 10-15oz
ft worry.
If your putting it onto a wood surface one “should” use epoxy resin vs laminating resin, it flexes closer to the rate of wood and can have better adhesion. Epoxy also costs a whole lot more as well. With that said, one “can” use regular laminating resin as well if cost is a issue(not overly recommended but it still works and lasts a long long time). Roughen up the wood a little bit to promote better adhesion and preseal the plywood with resin before laying up the cloth on it to prevent the wood from sucking up all the resin that you are trying to wet out the cloth with. . If all the glass is being used for is to seal off/waterproof the wood deck and not add significant strength the lighter the cloth you can go will make it easier, 10 oz cloth should do fine. If you don’t want the weave pattern of the cloth to show thru any paint you paint it with you can use a plastic squegee with some resin that has been thickened a bit with cabosil or similar to fill in the weave once the cloth is down and has set up.
Helps a lot when cutting the cloth to run a piece of masking tape on the cloth and cut thru it to prevent the ends from fraying and such, makes it a LOT easier doing the final sanding/cleanup without all those hardened frayed ends to deal with. Key word to wetting out the cloth is Stipple!!! Stipple!!

You should tell him the danger of breathing the epoxy with all
that. </font id=“blue”>
Good point Reelscape.
Use a charcoal respirator if doing it inside a garage or a fan to blow the fumes away and definitly a dust mask for doing any sanding on the glass. Some people cannot tolerate using epoxy resin at all, makes them break out in a rash, me, it never bothered at all, I actually love the smell of isothalic resins myself, but not the best stuff to be breathing in. pair of dishwashing rubber gloves is a good idea as well, once they get covered with resin you can wash them while still on your hands with some acetone before the resin kicks off. They start to glue themselves together if you don’t, making them a hassle.
