Loctite PL500 Landscape Block & Stone Adhesive, 10 fl oz, 12, Cartridge

This glue holds the cement blocks tight.

This adhesive is superb and I am really pleased with how strong the product is. It worked perfectly on the project I used it for and a little went a long way! I will continue to use this product in the future and am not disappointed with it's performance. A+++++

Sticks to blocks great

This really works well! We were putting up a three tier paver block wall and this was just the right product for that!

Happy with purchase.

Works great on my brown stone, a whole lot easier than tuck pointing with cement mortar for most just put back stone in place...

Be careful when you apply this adhesive, because it's soft and sticky. It has the consistency of toothpaste and the stickiness to adhere to rock and stone and wood and, uh, fingers. So try not to get it on your hands.It dries and hardens over a few days, turning into a solid that's nearly like stone.I don't yet know how well it will stand up to snow and water, but it works like a champ so far this summer.

I used this to set some pavers along the steps off my patio. I was hesitant because I figured they would come loose with use but they have been in place for months now and zero movement even with rolling heavy grilles and things over them. Much easier than trying to bed them in grout.
