Just works.
Needed to get a couple of 2m long railway sleepers on a concrete wall to make a bench. I didn't want to drill on the wall or the wood, so used this to secure the sleepers. Worked perfectly. Even with some overhang, they're perfectly secured in place. Added bonus, I'm expecting that with the flexibility, even if the wood expands or contracts, I won't have problems with cracks.

It sticks
Holy.... I use this to fix everything now. Fixed a leak in my bathroom sink. Hold the curtain rod in place. So many uses, so reliable

Expensive and Hard.
Needed in a hurry so had to pay premium price. It may have been old stock but it was hard to squeeze out of dispenser. It did stick down reasonably well but in my opinion no better than standard grab adhesive from Screwfix. I chose this product from reviews of best adhesives for my project and was somewhat disappointed.

I should have trusted the 1 star rating but allowed myself to be swayed by the YouTube video that the manufacturer clings to that says the product is amazing. Well, it’s amazingly bad but that’s it. Do not waste your money on this product. It’s impossible to get out of the tube and in the rare event you can get it out, the adhesive is almost dry and certainly won’t hold two materials together. Please buy something else - I wish I had.

Super strong. I’ve used it to hold the base of a birdbath that gets constantly wet. It grabbed straight away and so far, no problems

This stuff is fantastic. I had pieces of my curb break off. It was very uneven. I cleaned up the pieces and the concrete still attached and used this to attach it. It is permanently in place. It set up immediately and looks almost like nothing ever happened. I did buy a heavy duty caulk gun as they suggested and it worked great. Went on smoothly without any mess. Highly recommend this product.

This adhesive is thick and needs a heavy duty caulk gun. I too attempted to use a standard cheapo 5 dollar caulk gun only to find it would not work and broke when i squeezed hard. This does not mean the product is bla bla bla or defective, it means I was a cheapskate that bought several cheap caulk guns that always break. I ran to home depot and bought a heavy duty caulk gun and wouldn't you know it, the product dispensed with no issue AND worked brilliantly! When they advertise Hi-Grab, they mean it! One note, CLEAN BOTH SURFACES and if one is metal, rough it up with sandpaper to ensure a good hold. Here is a decent heavy duty caulk gun I bought to have a second on hand. https://www.amazon.com/dp/B01N0QGWAZ/

It's thick and is really strong. If you need something attached well it's worth the extra money
