The folks at the fiberglass place said one gallon will do 200 square feet on layers of resin that wet the cloth. With following coats of clear resin, one gallon will cover 350 square feet.
General Formula for coverage of Epoxy resin to fiberglass cloth. A general formula is to plan a ratio of 1:2.5 resin. This means for every ounce of cloth, you use 2.5 ounces of resin in a total of about 3 coats.
To build up 1/4 ” of biaxial fiberglass cloth, you would need approximately 8 layers. here
A cedar strip won’t sink to the bottom of the lake, and solo and assisted rescue work just fine without tanks. It’s a different story in canoes that don’t have the built-in buoyancy of a cedar strip. [links]
I usually do 2-3 (0.8 oz per pump of resin ) squirts of the resin and hardner at a time in small cup. I use a rubber squeege to spread epoxy and then use a small (6″) foam roller to spread a thin coat on the canoe.
Actually Cloth is stronger. It has continuous threads running in each direction. The mat is more like a bunch of small (1 to 2 inch) threads in various directions. here
How many layers of fiberglass do I need for my boat?
People also ask, how do I calculate how much resin I need?
If you plan to drag the boat a lot on beaches, the Xynole would be one of the best choices. Two layers of six ounce fiberglass, especially if both layers are saturated at once, isn't a lot heavier than a single layer and will still add a fair amount of abrasion resistance compared to painted plywood. here

A seal coat is an extra layer of epoxy, albeit a thin one. You'll need to purchase more epoxy if you're using a seal coat than you would if you weren't using a seal coat. Do not mix the epoxy for both the seal coat and the final coat at the same time, though. You won't be applying the final coat until the seal coat has cured. If you mix all the epoxy at once, it will cure in the bucket while you are waiting for the seal coat to cure. more
If you're preparing to add a coat of epoxy to something, you're definitely wondering how much epoxy you need. This is a question that brings a lot of stress for inexperienced epoxy users, because once you start mixing the epoxy you feel like you're in a race against the clock to get it mixed and poured before it starts gelling, and you want to have everything you need ready to go before you start.
Casting resin is thinner than coating epoxy, which means it spreads more and you could use a smaller amount of it to cover the same surface area. However, casting epoxies do not make good coats. Casting resin is really meant for use in encasing things for display, not forming a protective coating on a broad surface. They will not provide the same level of durability and protection as a coating epoxy will, because they are designed to be poured into very thick layers, rather than spread out over a counter top or a table in a thin layer. They simply aren't strong in layers that thin. [links]
A seal coat is a thin layer of epoxy that you apply with a brush. On wood or other porous surfaces, the seal coat prevents air bubbles from forming in the final epoxy layer. It's a thing enough layer that if air is bubbling out of the wood, it won't get trapped by the epoxy. You can just brush over that spot again after the air escapes. Then, once the seal layer has cured, you can apply the final, thicker layer of epoxy without worrying about air bubbles.
There is a general rule to help you understand how much epoxy you need. For coating epoxies, one mixed gallon (half a gallon each of resin and hardener) will cover twelve square feet at a thickness of 1/8 of an inch. This may vary by brand though, so always check the manufacturers instructions to be sure.
If any pigments, tints, thickening agents, or other additives are to be added, dispense them into the mixed epoxy, and mix in thoroughly prior to pouring. more
Most coating epoxies such as tabletop and bar top epoxy require thin pours of no more than ΒΌ inch per application. If these types of epoxies are poured thicker, you risk an accelerated reaction, which will cause the epoxy to heat up, which can ultimately crack, fish eye or yellow. Understanding the desired thickness of the final project is critical to calculating the necessary epoxy for a given project. For deeper pours, use a pouring resin which can be poured up to 2 inches in one pouring.
