[phatmanmike]

hey all, what happens when you fiberglass over 1/4" thick pvc.. i have a starnge idea about glassing over some pvc sheets i have, but dont know if the epoxy will melt it or anything else weird like that... im into making small boats and canoes with plywood, the stitch and glue way, but i wanna try to make a kayak like that, but use these 1/4" pvc sheets i have instead of plywood.....dont try an talk me out of it, unless it will melt

doubt resin will melt it, but proper adhesion may be an issue....

Nope,<br />No Melt......<br />Sand it good,+ rough, <br />It Might even Stick.........<br />Some Plastics you need to Polarize, with a Propane Flame.......

Epoxy resin will work fine for ya. Polyester resin will dissolve the pvc.<br /><br />c/6<br />Hooty

hey hooty....would you still polorize the pvc with a torch for adheasion like mentioned above???? ......to be glued in with thickened epoxy resin...<br />hermit

Re: fiberglass vs. PVC

Heck no. Epoxy will adhere to anything . Even tha crack of dawn. Wash the PVC with Dawn dish soap and water, rinse good and get after it.<br /><br />c/6<br />Hooty

Heck no. Epoxy will adhere to anything .

I'm not Sure about PVC,<br />But, for cross-linked Poly, You Must Polorize.....<br />And, Yes, this is for Epoxy......<br />Polyester Won't Stick At All.................

Hi,<br /><br />West system says their epoxy can be used on hard plastics, and they even mentioned PVC as an example, <br />But they say results may vary depending on just what type of plastic you are working with.<br />As stated you should ruff the heck out of it to make sure the epoxy has plenty to key into<br />I would try a small experiment with some scrap PVC to see how it works before you start the big project. I epoxied some short pieces of PVC pipe through my stringers for compartment drainage and I roughed em up real good with 50 grit paper. They ain't goin' nowhere.<br />H90
