HH-66 Vinyl Cement, 8 oz. can - Vinyl Adhesive, Cement Glue, Inflatables, Waterproof, High Strength, RH Adhesives

Works well for repairing pool toys and inflatable boats. Fumes can be quite strong so make sure you have proper ventilation. Using craft syringes makes application easy and the bond is stronger than the base material. Just make sure it doesn't get too hot as it can break down the glue.

I have a generic paddleboard that I modified with extra D-rings and straps using the HH-66 vinyl cement. This stuff has excellent hold in heat and wet conditions. The only problem seems to be the thinner outer layer of vinyl on the attached items. The thicker center of the D-rings is solid, but the outer edges are coming loose. I do not think that’s the cement though, because the same thing happened around my fin, and I had not glued anything there… but did use HH66 to patch it. The handles are newly applied and not tested yet. The D-rings were applied last summer and have held up great with tight bungee straps holding heavy weights… even with outer edges loose in spots. My spare paddleboard also had a leak somewhere around the seal where you pump it up. I applied a couple layers around the insertion piece for pump and the leak is gone. This is my second jar of HH-66 and I highly recommend it. My only caution is do not get any of it on your clothes and don’t get any around the rim of the container or it will be permanently sealed shut 😂

I wish I had this when I first put the headliner in. This stuff is awesome. Don't try to put the headliner in without it. It glued edges that don't wrap around anything, which is pretty cool.

Pro: it works wellCon: the remainder in the container will dry out within weeks after it's opened (some suggest storing in freezer?)Be sure you follow the steps seen in U toob videos or you'll fail to seal the leak in ahigh pressure IK or SUP.

Making a truck bed cover to replace a torn tarp, I got 2yds. of 18oz vinyl PVC fabric from Big Duck Canvas. Sewing this is possible, but we don't have a machine that could do the job, so I ordered the HH adhesive, hoping it would be better than contact cement: It is. Smear it on both surfaces, WAIT TILL IT'S TACKY, carefully fold over seams (or patch, etc.). It's stuck, solid - literally can't pull it apart. Get it right the first time, there's no pull it apart and repositioning possible. I'm guessing it chemically bonds to the vinyl - the smell is strong solvent - work it a ventilated area. Because there's no redo, I found working foot-long sections at a time was best.

Good product but be careful to use it up before expiration date.

I bought this to repair a large hole in my swimming pool liner which was just above the water liine. The product instruction tell you to paint both surfaces (i.e the liner and the patch). The patch was no problem but trying to paint the product on the liner below the water line was a disaster. As soon as it hits the water it spreads out in a thin sheet sticking to anything nearby including me (fortunalely it does not stick very well). I finally put the patch on without the liner being painted below the water. It adhered well where it was dry and less well underwater. The further down you went the less it adhered. We are planning to replace the entire liner after this season so I guess it does not matter, but I really needed an vinyl adhesive that can be applied below water. This is not it.
