HH-66 Vinyl Cement, 16 oz. can - Vinyl Adhesive, Cement Glue, Inflatables, Waterproof, High Strength, RH Adhesives

When you have to attach to vinyl, this is good stuff

Worked as advertised. Tried several other adhesives on reinforced flexible (billboard) vinyl and they didn't hold. This actually welded the pieces together and I could not pull them apart after a few hours.

The best adhesive I've found for vinyl

Just what I needed to fix my tarp. Wish the price was lower though.

Works as it should. Good Price

I had to repair an Intex explorer inflatable kayak. It had a small hole that I cut bigger to try to fix using fancy gorilla tape (worked for a little while, but was bubbling and obviously not a permanent fix), but that didn't work.So, I followed the instructions carefully, cut out a piece of extra raft vinyl, and used this to seal it. I then kayaked 8 miles of the Colorado River in the cold, and it held beautifully (all of my other patch attempts had not held air). It looks nice and permanent. Hopefully it holds for many more seasons---now I have enough to patch many more holes that are bound to happen on that kayak and several others I have for others to enjoy.

I bought this adhesive to fix large 132 gallon vinyl rain barrels.The hot-pressed seal line expanded under water pressure. The opening are either hairline, pin hole up to about 1 mm, or crack line no more than 1/4 inch by 1/32 of an inch.I applied 2 coats from both inside and outside (one each time then let it dry fully for 2 days at temp >60 deg F). It works well afterward.For larger rip, an addition piece of vinyl is required. Cut the patch to cover at least 1/4" to 1/2" from the nearest edge of the rip. Then apply the adhesive to the patch, wait for a few seconds (longer if you're doing this at temp below 50 deg F and immediately if you're doing this in 80-90 deg temp), and press the patch onto the hole. Let it dry in open space.Follow the manufacturer's safety guidelines on the can. Do this out in the open, well ventilated space away from any potential ignition sources. Avoid inhaling while using it.

I needed to build a custom PVC box to mount a utility box on the side of my house. With vinyl siding you don't really wanna just go screwing utility boxes into the siding, and I couldn't find a box that looked right, so I made my own. In order to weld the PVC together I used this product. It sticks pretty quickly, dries very fast, holds well, and doesn't leak if you did it right. It does smell bad, so make sure you use it outside.
