LOCTITEPL 500 Landscape Block and Paver VOC Construction Adhesive 10-Ounce Cartridge (1654392)

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.

Sticks to blocks great

Seemed to work as advertised. Held tight after only 24 hours. Interested to see if it survives a cycle of seasons.

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

So I only needed this for a small project to fix a stone that fell off the side of my house. When I got this I popped the seal, cut the tip, and then had it struggle a bit. Even though the seal was opened, I'm assuming a part of it was hard and clogged it, which in turn put too much pressure on the canister, so it popped the top off making a mess and unusable after the first use. Got what I needed done, but the rest was a complete waste.
