Technical Info
My Hands-on Test: Henry’s Adhesive

It’s only been down for a week, so I can’t be certain about its long-term performance, but so far, the vinyl tiles are staying on the plywood.
✅Pros: Henry’s Adhesive
Incredible Grip
The first thing that impressed me was its incredible grip. It holds everything in place securely, which is exactly what I needed for my custom cutting and installation.

The adhesive doesn’t set up extremely fast, giving me more time to achieve a proper application. It’s easy to use and provides excellent adhesion, surpassing all the other adhesives I’ve used before.
Good Performance
In terms of performance, the adhesive has pretty good stickiness, and it doesn’t take a really long time to dry, which is cool. However, I did notice that it takes several days to dry on two non-porous rubbers, but once it does, it sticks well. On porous surfaces, it dries overnight or in just a few hours, which is impressive.

Ease of Use
In terms of ease of use, Henry’s Adhesive is top-notch. It comes ready to use right out of the container, eliminating any need for additional mixing or preparation. This convenience saves me time and effort, allowing me to focus on the task at hand. It has a thick consistency, which makes it easy to apply without any mess or splatter.
❌Cons: Henry’s Adhesive
The product is easy to use and spread out. However, it took longer than expected to seal. It actually took more than 24 hours to fully set, but once it did, it worked great!
One thing to note is that the tiles tend to move immediately after placing them, so you’ll have to backtrack each time you lay a new tile to ensure they’re flush.

FAQ: Henry’s Adhesive

A: Henry’s Adhesive is effective on various surfaces, including concrete and wood. It is crucial to ensure that the floor is clean, dry, and above 65 degrees for optimal results.
Q: Can I use Henry’s Adhesive for repairing luxury vinyl planks? I have a few planks that need to be re-glued.

My Hands-on Test: JB Weld Plastic Bonder

✅Pros
Although the crack wasn’t significant, I wanted to prevent it from becoming larger, especially considering the potential abuse the deflector could face. Replacing the entire part seemed expensive, so I opted for this adhesive.

Easy to Apply
Applying the J-B Weld adhesive was a breeze. I was initially concerned about its adhesion to the deflector since I wasn’t sure about the type of plastic it was made of, but it worked perfectly. Once the adhesive cured, I was pleasantly surprised by its appearance. It blended seamlessly with the deflector, and the only noticeable difference was a slight variation in texture, with the adhesive being smoother.

Enduring
It has been four years since I made the repair, and I’m happy to report that there have been no issues with the adhesive or the area where it was applied. The crack has remained unchanged, despite the constant vibration and punishment the deflector endures while cutting the grass on my 4+ acre property. This durability is impressive and far more cost-effective than purchasing a new deflector.
JB Weld Vs Gorilla Glue
J-B Weld Original is steel reinforced, has a tensile strength of 5020 PSI and can withstand temperatures up to 550 degrees Fahrenheit (287 degrees Celsius); gorilla glue is nice for repositionable, gap filling, paintable, easy to dispense

Versatility
I have used this adhesive for various other applications, and it has been effective in all of them. One instance was repairing a cracked plastic table foot.
❌Cons
JB Weld Plastic Bonder is black in color, which may not be ideal for all applications. If you are using it in a visible area where the glue will be noticeable, it’s important to take this into account.

FAQ: JB Weld Plastic Bonder
Q: Can I repair a long crack in a plastic tub of a dehumidifier by super gluing it and applying a protective coating to prevent water damage to the bond?
A: I have successfully utilized this method for various repairs. JB Weld becomes waterproof when applied and acts like plastic. Considering its affordable price, it’s definitely worth giving it a try.
Q: Can JB Weld bond HDPE and LDPE plastics together?
A: It is likely capable of bonding HDPE and LDPE plastics.
Q: What is the temperature resistance of JB Weld?
A: JB Weld is versatile and reliable, suitable for both indoor and outdoor use. For specific temperature-related inquiries, I recommend contacting the manufacturer.
Q: Could I use JB Weld to repair the cracked touch screen on my smartphone?
A: JB Weld can prevent the cracks from worsening. However, it is likely to disrupt the functioning of your touch screen and may void your warranty. Therefore, I do not recommend using JB Weld for that purpose. T7000 is a better choice. You can see my test here: b7000 vs t7000
Q: Is this an epoxy or just an adhesive? Is it stronger than Gorilla Epoxy?
A: Two years ago, I used JB Weld to bond my car bumper to the fender area, and it is still securely in place. I can vouch for the effectiveness of JB Weld.
Q: I need to fill a gap in a plastic anvil caused by a cutter blade. Should I use JB Weld or J-B Weld 50132 PlasticWeld?
A: I’m unsure about your specific situation, but the Plastic Bonder does offer some flexibility.
Q: How does JB Weld perform in high temperatures?
A: I can share my experience of using JB Weld to glue together interior trim pieces of a car in the Palm Springs, CA area, where temperatures reached 122 Fahrenheit this year. Despite being exposed to extreme heat, the JB Weld adhesive held up exceptionally well.
Q: Can you patch a plastic gas tank with JB Weld?
A: Yes, it should work. Just ensure that you thoroughly clean the repair area before applying the adhesive. It’s a great product for this purpose.
Q: Is this the appropriate epoxy for bonding plastic pieces that will endure significant vibration? How flexible is it in terms of ductile strength?
A: While JB Weld is suitable for bonding plastics, it is not particularly flexible or ductile. It tends to harden and become rigid.
