Fiberglass cloth is a woven material available in various sizes to allow custom strength, thickness, and weight in projects. Fiberglass cloth provides great strength and durability when layered with a resin to form a hardened composite.
Fiberglass cloth has many advantages: It has greater tensile strength than steel wire of the same diameter, it has excellent fire and heat resistance, it has exceptional thermal conductivity (making it useful for insulation applications), its chemical resistance properties are similar to glass, and it's very durable and economical.
The description says a pack, 38" x 3 yards, yet the drop box says 38" x 1 yard. Which is it?
Use the drop down arrow next to the price to select the length you want.

Hi,What 'oz' fiberglass would be good to cover a new plywood deck?John D
I used 10 oz. on my replacement plywood decking and it was fine. Just have plenty of epoxy on hand, you will use more than you think.Ted
I honestly don't know precisely. I used 10 oz to cover the bottom surfaces to protect them, and to reinforce plywood joints, which was quite adequate. If your objective for your deck is not for reinforcing, but to provide a non-slippery surface for example, then 6 os may be adequate.

6oz is fine. If you go too heavy the weave will become visible.
How many square feet will a 38" X 10yard cover?
I agree with John D
95 sq ft 3'2"X 30'=95 sq ft
90, assuming you overlap 2" out of the 38"
Sir, I am rebuilding a 1965 Glasspar Avalon 14ft boat, I tore out the original boat carpet, then scraping the carpet adhesives out, which in turn, some of the fiberglass areas came out, this was above the wooden floor, which fiberglass cloth and adhesives to apply the new fiberglass down, prior to putting new Shaw marine carpeting onto the floor. Thank you for your assistance?Charles Dorman, Tacoma,WA
I'm not sure what your question is. Are you thinking of using the fiberglass cloth to replace the fiberglass areas that came out after scraping? Unfortunately, I didn't use the cloth for similar purposes and therefore can't answer the question. I used the cloth to act as insulation in back of an electric heating element which when electrified, became hot and was used to soften and shape light plastics. Once the heating element got hot, the cloth protected the wood backing from burning by acting as insulation. It worked great for that application.
I only have experience with general fiberglass repair. That being said, if it will be covered with carpet, then I would use 10 oz. fiberglass cloth and epoxy resin in a standard repair situation - sand it out, and cut increasingly smaller patches, and then laminate all together. Easy-peasy.
I used a fiber cloth and fiberglass resin from a local automotive store. If you need a little more support I would suggest a heavier fiber cloth. If you are just trying to cover up the areas that it pulled out of you could probably get away with a lighter cloth.
I was applying fiberglass cloth to the bottom of a plywood boat I am building from scratch. I used 10 oz. cloth and West Marine epoxy (205 resin with 206 hardner)I followed the instructions suggested in the West Marine epoxy manual. I must caution that I am NOT an expert and was just following instructions, but they seemed to work pretty well in my case and I don't see why they should not work in yours. Just sand the surfaces well before applying the epoxy/cloth.

Can I use it in steam pie?
Can I use it in steam pipe?
I am puting a new floor in a 20 center consol..wood is down should I use mat or cloth and what weight?
Use fiberglass cloth. Ten ounce is plenty heavy if you are going to be stomping around on the deck. I assume this is going over plywood. You might also consider Dynel cloth. It soaks up a lot of epoxy but makes a nice non-skid surface.
I contacted you before about my boat it is 16 ft long,it is shaped like a kiyack.I want to glass inside and the outside.f i add the sides and bottom and top it comes to89 inches. What tools will i need and how much resin and hardner. Last time you said around 9 packages of cloth. would you sugest 6 oz or 10 oz? You said a roller and spreaders.
Hi Ronald,For a boat that size, six-ounce glass will almost certainly be enough; 10-oz cloth would likely add unnecessary weight. You'll want a gallon of resin, with hardener, to put on at least three coats: one to wet out the cloth, another to fill the weave, and a third for sanding. You don't need a roller to apply cloth or glue, but you'll need plastic spreaders, and razor blades to trim your cloth.The big issue with this job will be sanding. The best tip I can give you is: minimize it. Some will be necessary; how much will depend on the degree of perfection you pursue in your finish. You'll want a random-orbit sander, with dust collection, a good mask, and plenty of 80-grit paper. You can cut down on sanding by using an epoxy that doesn't blush. The best trick of all, though, is to use cabinet scrapers instead of sandpaper whenever possible. When you're working with epoxy, a scraper is your best friend.--Tim.
Good stuff to repair broken things
My car's rear view mirror's cover was broken, but I don't want to replace the whole mirror because everything else works. So I used epoxy to glue a layer of fiberglass cloth on both inside and outside of the mirror cover. After the epoxy cured, the strength is enough to withstand the wind on the road.
Found the "right stuff"
I wanted to line my Halo costume with fiberglass but I needed to do multiple layers with the stuff you get from auto part stores. This 10 oz fiberglass was perfect! I could use one layer and it was stronger and quicker and cleaner looking. Very happy with this product.
The product was easy to lay out and form to the hull. The 25 yard roll with no inner core was sligjtly difficult to roll out and keep on the hull alone. It worked well, absorbed/ wetted easily and i found it stayed bonded to the wood once cured without air pockets forming underneath.
i would buy this again
Would be easier to roll over the boat if the roll had a core.
Excellent data on this product
Am building a wooden/plastic resin boat and will need about 60 sq yds to glass outside of the boat. It was suggested that because I was doing the work myself, to work with one sq yd pcs. This saves being wind blown, both in the cutting of the material and in taping onto the surface. Each sq yd comes in a Ziploc type bag and very easy to use. I lose some yardage because of overlapping but that's better than working with a large piece that I have to really hustle to fill with epoxy.

Very good product! worked very well
I had to replace the belly fuel tank of my boat and found the stringers and structure to be water damaged. I replaced the entire stringer structure and cockpit deck and used this type fiber glass cloth and 2 part expoxy for all wood covering and structure bonding, finished with Interlux bilge paint. New deck top will be gell coat spray on.

Worked fine for me.
Used it to glass the bottom of my new 16' lumber yard skiff.
