> 3 dayIve been struggling with a cracked pool step for a few years. Ive used two step epoxy sticks and flextape, and other quick fixes. I finally got fed up when the step developed a new crack. this stuff is awesome. I applied white pigment for epoxy before I added the hardener to the epoxy and stirred well. I added the hardener as stated in the directions. I also used this 3m bondo fiberglass cloth just to give extra trength because the step seems hollow underneath and dips in the middle. worked out great. the directions state it has a 12 minute work time after the hardener is added. poured well and covers easily with a cheap paint brush. it hardened in just an hour. cure time is 2 hours. the key is to stir for several minutes after the hardener is added. dont be lazy in this step. it has to thoroughly be mixed, paying close attention to get the bottom of the container you use to mix it in. if you dont, the stuff on the bottom, after you pour, will be on top after pouring and will be tacky and not cure properly if you dont mix it thoroughly. i am very pleased. its easy to use. i cut this to size, poured a thin layer of epoxy, then laid the cloth. i poured another thin layer of epoxy over it and brushed the epoxy into the cloth, saturating it and removing air pockets. then i poured the rest of the epoxy to cover the whole project. the step is strong and waterproof now. all cracks have been fixed and reinforced by this cloth and epoxy.

> 3 dayI have used this fiberglass cloth to repair a bathtub and now my pond insert. This is sturdy, has great adhesion when used as directed, and is fairly easy to use. Great price for size of fabric sheet

02-06-2025Good stuff. I needed a woven fiberglass that would be able to flow in, out and around the contours of a boat transom and stringer joints, this is just the right thickness to work with. 3 layers of this with 3M polyester resin and a few smaller pieces of 24oz cloth to reinforce corners gave me just the right strength but kept it thin and lightweight. Thanks Amazon!

> 3 dayProduct measures 25.5 X 47 inches rectangular. Some have said that this is a heavy cloth but in the world of fiberglass cloth this is really a light to medium weight. It came folded so close and tight that at the fold corners the weave has separated. See attached pic. So if if doing a layup of several layers this is really not much of a problem. If however you are doing a finish cover to be exposed to the view of the world like my present use it is detracting since it has these weave separations in about a 5 X 5 inch pattern over the entire sheet. If this is your case you might try to find the cloth which comes off a roll.

> 3 dayLarge enough for any D.I.Y job. It worked well to fix cracked plastic using epoxy but I am getting proper resin and hardener for fiberglass.
