HH-66 Vinyl Cement 16 oz - Waterproof PVC & Vinyl Glue for Pools, Tarps

Give me a great review on this product. HH-66 Vinyl Cement 8 oz The HH-66 Vinyl Cement 8 oz is one of those products that earns its reputation the hard way — by consistently working when cheaper glues fail. If you need a strong, flexible bond for vinyl repairs, this cement delivers professional-level results without the hassle. What makes HH-66 stand out is its incredible holding power. Whether repairing torn boat seats, inflatable gear, tarps, awnings, pool liners, truck covers, or outdoor furniture, it creates a tough waterproof bond that holds up against heat, cold, moisture, and heavy use. Unlike many adhesives that become brittle over time, HH-66 stays flexible, which is critical for vinyl materials that bend and stretch. The application is straightforward, and the cement grabs quickly without requiring complicated tools. Small repairs can often be completed in minutes, and once cured, the repair feels solid and durable. Many users also appreciate that it works well for both patching and seam sealing. Another big advantage is reliability outdoors. Rain, sunlight, humidity, and temperature swings don’t easily break down the bond, making it a favorite for marine, automotive, and recreational repairs. A little goes a long way too, so the 8 oz can lasts longer than expected for most household or hobby projects. Pros: Extremely strong vinyl-to-vinyl bond Waterproof and weather resistant Flexible after curing Excellent for marine and outdoor repairs Fast tack and easy application Trusted by professionals and DIY users alike Things to know: Strong fumes mean good ventilation is important Works best when surfaces are properly cleaned beforehand Dries quickly, so precision helps during application Overall, HH-66 Vinyl Cement 8 oz is a top-tier adhesive for anyone serious about repairing or bonding vinyl materials. It saves money on replacements and provides repairs that actually last. For DIY projects, marine use, or emergency fixes, it’s hard to beat.

This is something that if you make any vinyl repairs to your pool is a must. It behaves a lot like PVC cement but it's not the same thing. I have noticed that many big box places will not have this on the shelf. Best way to use it is clean the area you are applying the patch, pre-cut the patch and then apply the glue liberally to one side of the patch. Don't put the glue on the liner. You can apply this underwater if you want. Do this before the sun hits the area to be patched, before the sun gets it hot or after the sun goes down. If you apply it to a patch and the surface is really hot, you will get poor results. One trick I've discovered this year is how to apply it better. I take a regular old dinner plate, lay the pre-cut patch on it flat and coat it with the glue. This works very well at getting an even coat and the patch doesn't stick or get dirty. And, you have a firm flat surface to apply the glue brush. The last thing you want to have happen is to hold the patch in your hand, try to coat it with this glue and drop it on the ground. You've ruined your patch and used up some glue. Once applying it, it depends on where you're putting it, but if above the waterline, I like to put a clamp over it for a while to make sure it sets the way I want it. Or you can sometimes hold a board or something rigid behind it to press it firmly. When it sets, it's not going anywhere. If it's under the waterline, some people fold it over until they're right at the spot to put the patch. You can put this underwater. Above or below, the real secret to getting a good adhesion is taking a plastic spatula and smoothing it out to get the air bubbles out. If you have a pool that has an inflatable ring that a cat or other animal has clawed, this will patch it but it's really not worth the time to try to do and come back later to see if it'll hold air. this is more designed to hold water back than it is to hold air in. I let it cure for a 24 hour period, came back with soapy water in a squirt bottle to test it. Some patches held and others had one leak making it very difficult try a second time. I finally decided to go another route. The best way to fix that is cut a slit(s) on the outer part of the ring away from the waterline just big enough for an empty two-liter soda bottle (with cap on) to slip in. You may want to make around four slits around the pool and insert these empty soda bottles. You want to pack them in but not so tight that it stretches the ring. If you stretch it taut, the sun will crack the vinyl. After getting the soda bottles the way you want, cutting a strip of a vinyl patch and using this glue will solve your problem. I've never had any problem with this method and it holds up the pool, keeping the water in. You can add the noodles inside with the soda bottles and it'll work just fine. The sun will not degrade either inside the ring. The sun will degrade a noodle left in the pool but not the plastic soda bottle. One can is likely going to be enough to last you for your needs. But, like PVC cement, don't expect the unused portion to still be liquid the next season. So, use it liberally. This is the best type of glue for vinyl pool patches that I've found. Now that you have the best glue, pair that with quality patches. Cheaper, thin patches will pucker up with this glue and you will get poor results. One thought on the patches, pre-make your patches so that you can apply them one right after the other. Match it to the hole and make it bigger. You can center the patch area on the liner and mark it very lightly with a felt marker, just enough so that you know where it goes. When you make your patches, always make them rounded. Don't make corners that can catch on something. The goal is to get the glue on the patch and vinyl liner but not coating the patch with glue on the edges outside the patch. To clean the vinyl liner, soapy water will work followed by rubbing alcohol or just rubbing alcohol. Any stronger chemical I would would do a test patch as it could dissolve the patch or liner. If it starts to get gummy, you don't want to apply that cleaner on either the patch or liner.

The glue worked great however, the first two times I bought it to can was less than half empty. The last can I bought the third can was 3/4 full.

I used this to fix the D-ring pads and "daisy chain" attachment to my Tahé SupYak as well as reinforce the seams and hopefully extend the life of the inflatable paddleboard. Ease of application was ok, although a little bit messy with the brush attached to the lid that did tend to shed a little. It seemed to sorta blob on thickly and was a bit tedious as I ended up having to smear it around with my fingers because the brush quality wasn't great and just made more of a mess. It also does dry pretty quickly, but that's a good thing as it needs to dry enough to be tacky on both sides you're gluing belt sticking them together for the tightest grip. The 8 ounce jar was plenty for what I needed, even glopping it on so thickly and I still have some left in the event I need to fix or secure a couple more spots. It seems to be pretty durable so far, I've only used it a couple of times since gluing it, but it's all holding up well so far. I will see if it stands the test of time. I have hopes that it will. In all, I'm happy with this purchase so far, and would recommend it to a friend for family member. In fact, I have. The one star was removed for the brush shedding and the application being a bit more messy and thicker than necessary. Perhaps a separate brush not as thick and not stored in the lid would be easier. In order for one to get that now, he/she might have to buy a paintbrush separately to get to spots that are harder to reach than the thick nubby brush that is included can reach and fit between.

We'd stored our inflatable Hobbie kayak in our hit garage. After 2 years 10 if the attachmend pads popped off. This was the recommended glue. I followed all the recommedwd steps and let it set 48 hours. They are firmly attached again! I also repaired my leather phone case/wallet. Just be sure your in a well ventilated space away from flames. Very happy with it. Just hope it doesn't harden in the can befire I need it again

I had never heard of this before. I used it as a secondary layer of defense/repair on some failed boost seat seems that I first re-stiched with curved needles and top marine thread from sail rite. I used a double needle approach found in YouTube... After sewing was completed, I first cleaned the area thoroughly with 91% rubbing alcohol. Then I used a baby medicine syringe to apply about an 1/8“ coat of the HH-66 (I did not use the included brush) to the immediate center of the repaired seem, then flattened that slightly to cover all thread holes too. About 30 minutes later, I applied another bead, but just let gravity cause it to flow towards flat. I then let the seats sit flat for 24 hours and immediately put them to work on a day of boating with my family... The seams did not fail or show any signs of pending failure... Application could be messy if your not careful... Mind drips or cover other areas to protect. This stuff does dissolve the vinyl slightly, so will cause issue if applied where you don't want it... It dried crystal clear, and was rubbery, like soft vinyl. It also rejuvenated the crispy edges of the vinyl where it have been torn, making them softer too which I'm sure will contribute to the repairs lasting...

Excellent for under water repairs on an Intex pool. Rip at the side bottom of a 52 inch repair under water. Tried others and the patch came right off NOT THIS ONE! POOL IS FIXED!
