Best Urethane Adhesives of 2026

"I used this on my 2009 Audi A4 convertible's rear glass window and was impressed by its amazing sticking power and quick drying. I highly recommend using the primer and applying the adhesive with care for a clean repair. Take your time and use gloves, and you'll get great results."

"After my convertible glass fell out during a heatwave, I used this product with the recommended primer. The adhesive cured rock-solid after 48 hours and saved me from replacing the entire top. Applying it was a bit intensive, but careful trimming and patience paid off."

"This product did a great job reattaching the rear window to my wife's 2006 Crossfire Roadster. When used in combination with the 3M primer, it offered a durable, long-lasting bond. The total project cost was reasonable, and planning ahead made the process manageable."

"As a semi-professional woodworker, I rely on this polyurethane Gorilla Glue for joinery. The bond it creates is impressively strong and reliable, and the longer working time makes assembly much easier compared to standard yellow glues. It can be a bit messy if you use too much, but with a little practice, the results are outstanding."

"I've used this glue on everything from wood projects to outdoor repairs, and its waterproof, incredibly durable hold never disappoints. The expansion helps fill gaps and it sticks to almost anything. Just be sure to lightly dampen surfaces and clamp well for best results."

"This original Gorilla Glue is my go-to for heavy-duty repairs. I've trusted it on wood, PVC, and even concrete-to-wood bonds, and it's held up great over time. As long as you follow the instructions and avoid over-applying, it's a dependable choice for tough jobs."

"I found that warming the tube made application much easier, and the caulk flowed smoothly using a regular caulking gun. The adhesive held my excavator door glass securely even in cooler temperatures. Cutting a V in the tip after the angle helped lay a perfect bead."

"After a few tries, I learned that heating the tube is a must for easy application—otherwise, it's tough to work with. It's been reliable for sealing windshields and body cracks on my vehicle, and although it's very messy, it cleans up with isopropyl alcohol. Gloves are highly recommended!"

"I used this to seal a leaky window after a poor install, and it completely solved the problem. Saved me a trip and dealing with another repair company. Great product for fixing leaks!"

"I always keep Gorilla Clear Glue on hand because it delivers a strong, crystal-clear bond for all my workshop and DIY projects. Whether I'm joining wood, metal, or making leather strops, this glue never disappoints. The fact that it's water-resistant and easy to work with makes it a permanent staple on my workbench."

"This glue is perfect for jewelry making and small repairs. I've learned to avoid clogging by keeping the cap clean and upright, and even if the top gets sticky, a little effort gets it working again. Durability is top-notch—just be sure to let it dry thoroughly for best results."

"Compared to other glues I've tried, Gorilla Glue stands out for its easy-to-use, clean applicator and consistently strong bond. Clean up is simple with soap and water, and I appreciate that the applicator tip is easy to clean even after drying."

"When it comes to construction adhesives, this one has exceptional bonding strength—in fact, it's the best I've tried from Loctite. While it's definitely thick and requires effort to get out of the tube, that's precisely what creates such a strong, rock-hard hold. I also appreciate that it's sandable, paintable, and even works well as a filler for cracks or nail holes. Overall, it's a top-notch product for demanding jobs!"

"I used this adhesive for installing new stair treads and was impressed with how well it performed. However, I have to mention that it's very dense, and a regular caulk gun just couldn't handle it—my 12:1 ratio gun even broke. Upgrading to a 24:1 thrust ratio made a huge difference, and the product dispensed smoothly. For anyone planning to use this, I strongly recommend a high-thrust caulk gun."

"From my experience, Loctite PL Premium Fast Grab Polyurethane Construction Adhesive didn't quite deliver the long-lasting, high-strength bond I expected. It works fine for temporary fixes or lighter repairs, but for projects that require robust, permanent adhesion, I found it lacking. The easy application and quick set time are nice, but I would look for other options for heavy-duty tasks."

"I used this to replace the windshield on my Chrysler Town & Country, and the results were fantastic—super easy to apply, bonds tightly, and there were absolutely no leaks after curing. The included gloves were a thoughtful addition, and I truly believe this is a professional-grade product at a great price. I’d recommend it to anyone handling windshield installations."

"I used this sealant for my rear windshield and found it to be very easy to work with and provided plenty of time before setting. The adhesion is extremely strong—so much so that removing the glass later will be tough. Be cautious, though, as it’s sticky and can be a pain to clean off your hands."

"This is a great product, but I learned that it’s much easier to apply if you warm the tube up a bit beforehand. Otherwise, it can be pretty tough to squeeze out. A sturdy caulking gun is a must."

"I've used this glue on all sorts of surfaces—wood, plastic, glass, and more—and it never disappoints. The bond is incredibly strong and holds up over time, even outdoors thanks to its waterproof formula. Just a small amount goes a long way, especially since it expands as it dries, filling in any little gaps. I always keep this on hand for repairs because it's so reliable and versatile."

"I had some loose bricks in my backyard and decided to try Gorilla Glue. Once it set, those bricks were rock solid and didn’t budge—even years later when I took down the wall! I’ve also repaired a coffee cup handle with it, and it’s held up for over a decade. It can expand and leave a yellow residue, but the strength is unbeatable so I just scrape off the excess after it cures."

"I recently used this glue to fix a tile on my walkway and it’s now firmly in place. The drying time is quick—about 10 to 15 minutes—which made it easy to fix some loose veneer and even ceramics. Just be careful not to get it on your skin because it’s really tough to remove!"

"I’ve relied on this glue for years and it’s never let me down. The strength is incredible—I’ve used it to bond wood for heavy projects and even for repairs like attaching a felt seal inside a dryer. It stands up to heat and moisture effortlessly. You do need to remember it foams as it cures, but if you follow the directions, the bond is unbreakable."

"As a semi-pro woodworker, this polyurethane Gorilla Glue is my favorite for joinery. It gives me plenty of working time and actually makes assembly easier since it doesn’t tack too quickly. Once cured, the joints are rock solid. It can get a little messy if you use too much, but it’s absolutely worth it for the reliability and strength."

"I use this glue for all sorts of projects from wood furniture to PVC to concrete. As long as I dampen the surfaces and clamp well, it’s always dependable and forms a super strong bond. It does expand, which is great for filling gaps, though I watch for squeeze-out. I keep a fresh bottle on hand at all times because once opened, it doesn’t last forever."

"I really liked this product for quick spot repairs. The small tube made it simple to use just what I needed, and it sealed tightly for storage. Once cured, it was just like solid rubber—absolutely perfect for fixing the side of my windshield."

"I used this polyurethane adhesive to install a rear window in my RAM 2500, and the results were excellent. The adhesive flowed smoothly and was easy to apply, even at moderate temperatures. For anyone looking for a reliable polyurethane, this is my go-to recommendation."

"This windshield adhesive was just what I needed for a small crack repair. It came with an applicator tip, was easy to apply, and cured much faster than I expected. The bond is extremely strong, weatherproof, and cost-effective—much cheaper than dealing with insurance. You can't even tell my windshield was ever cracked!"

"I always keep Gorilla Clear Glue in my workshop because the bond is dependable, it dries completely clear, and it stands up to humidity and moisture. It’s my first choice for joining wood, metal, and leather in my DIY projects."

"I use this glue for jewelry making and repairs. It holds fused glass pieces securely and is extremely durable, but you need to follow the directions for best results. The only downside is the top might clog if left open, but it’s easy to clean."

"This glue is a great all-purpose option when you need a strong bond and a clear finish. The applicator is convenient, and cleanup is simple with soap and water. It’s second only to epoxy in my experience."
