HH-66 Vinyl Cement



Customer Rating:


Product Description

HH-66™ vinyl cement makes strong seams on vacuum bags. Each can has a built-in brush attached to the lid for easy application. This vinyl cement is clear, fast drying, waterproof, and remains flexible. HH-66 has a nearly instant bonding action on most vinyl surfaces when prepared and applied appropriately.

This product is designed to work with vinyl membranes and sheeting. However, we have found that it will also bond our polyurethane sheeting if the material is cleaned with acetone or xylene and lightly abraded with a synthetic wool pad. Polyurethane material requires clamping for 24 hours for a successful bond.

HH-66 dries quickly with a very strong, yet flexible bond. It is not affected by weather and temperature extremes, and is highly resistant to oil, fuel, grease, and many other chemicals. The 1/4-pint (4 oz.) is enough to build one large (4 x 8) vinyl vacuum bag or several smaller bags.

About Our Pricing: You may notice that our price is higher than many other suppliers. Search around online and you can save a few bucks. Our pricing is higher because my wife and I had to take a very expensive training class just to be able to ship this product. We don't sell much of this adhesive so it's going to take time for us to pay off that expense. We are currently selling HH-66 at our net cost.

Update: The manufacturer has been raising prices by significant amounts - there have even been multiple large increases in a single year! I recently tested a few other vinyl cement products and I believe they all work about the same. So if you can find a less expensive option, it should work fine on our vinyl and polyurethane.

Product Reviews

  1. Excellent Hold, Fast Drying

    Review by Crystal Tucker

    This glue is incredible. Do be aware that it has a very short working time, but it REALLY sticks, and fast. We used this for patching am industrial high-speed door (a thick vinyl material) but I highly recommend it when you need something to really stick!

  2. Pond Linder Project with Billboard Tapes and HH-66 Cement

    Review by Michael Povia

    HH-66 cement does a great job bonding vinyl billboard tarps together; we are using them as a pond liner for 120' x 120' pond. Thanks to Joe and Christine our orders are filled and shipped quickly. We will definitely return because of their superior service and great pricing. Thanks Guys!

  3. Review from Grand Junction, CO

    Review by Bart Day

    We used this on the awning on our old trailer and it never came loose or started to peel... we owned it probably 5 years. We are now needing HH-66 on our new trailer awning.

  4. Review from Chadds Ford, PA

    Review by Jim McAndrew

    I found this product recommended by many sources as the best for repairing vinyl pool covers. However it is difficult to obtain and expensive. I was very happy with the price and fast delivery from Joe.

  5. Satisfied and Then Some

    Review by Rick Wargo

    Joe's custom bag making article was the inspiration for me to make several vacuum bags for my press. He recommends the HH66 vinyl cement and I can attest that this is a superior product. You'll find that it bonds vinyl in such a way that the two pieces almost melt together and become one piece. For the torture that I subject my vacuum bags, such strength is essential. Two thumbs up and five stars.

  6. Exactly As Advertised

    Review by Sean Osborne

    I have purchased from Joe several times now and the experiences have been nothing but positive. The HH-66 does exactly as advertised. Thanks again Joe!

  7. This Does The Trick

    Review by Ka Harms

    Not only does HH-66 do the trick on vacuum bags, but it does wonders on pop-up campers that have mice damage on the canvas and need patched up tight. We repaired 20 large holes and we are leak free! We have nick named her, Oh... patchy!

  8. I Couldn't Tear It Apart

    Review by Benjamin Batilidge

    I was suprised by how easy it was to build the vacuum bags. The hh66 bonds the vinyl permanently. I couldnt tear it apart if I tried. And since it dries clear, the seams look professional and almost invisible.

  9. I Love Building Things

    Review by Frank Jenna

    I am a part time woodworker but a full time tinkerer. I was going to buy a premade vacuum system but I love building things on my own and this vacuum press was just what I needed. I built a bag that was 6' long and 2' wide with the vinyl here and it worked quite well. One thing I did notice is that you definitely have to "paint" the seams as Joe suggests in the article part he calls "the secret". This made a huge difference and now my bag is 150% air tight. Last night we did a curved panel for a small drawer front and the vinyl was did the job very nicely.
