Customer Questions & Answers

I bought one tube and couldn't squeeze any out, figured it had gone bad. Got another tube, it won't come out either.

Am I doing something wrong, or just got two old hard tubes of the stuff. irritated to have to go a 3rd time to the store.

Can this be used to around an outdoor fireplace?

What's the max temp rating?. I'm thinking on using this to hold blocks one on top of the other (not to hold them to the sides of the fireplace). The actual fire box is covered with fire blocks, so the adhesive won't receive direct heat.

This application with High Heat, I have never used.But seems to work with everything and stays but forever.. Golf Shoes I would be careful not to get to close to the edges.Keep Paint thinner close just in case it oozes out , not to make a mess!

I'm getting ready to build a raised garden using concrete blocks. Can I use this between layers to secure the blocks? Is it safe for use around gardens (IE will it leach into the soil and harm the veggies i'm growing?)

Can this product be used to stick smaller river rocks together to form a "barrier" between yard and mulch?

Asked by: Yardfixer1
I don't see why not. But be careful applying it as it does not dry clear. You would probably have to dot the rocks as you lay them.

10 fl.-oz. PL 500 VOC Landscape Block Adhesive is rated 4.0 out of 5 by 20.

We put together a retaining wall around a pool and glued it all together using PL Landscape adhesive. It started to set in an hour or so and was fully hard in less than 24 hours. We just received 4 inches of rain in less than 3 hours and the wall is still holding up great! That wall is not going anywhere thanks to PL!

Rated 5 out of 5 by from homestone I've used over 175 tubes of this and it works. I use on all landscape block (even with lip) not just the caps. No problems. I use about a tube for every 7 or 8 blocks. Capstones about the same rate. If working in the hot sun, you had better get it on, check it a few times (tends to slide around some). The next day you will need a chisel and hammer to pry off. Make sure your blocks are clean and dry. Adhesive doesn't stick at all to a damp surface.

Rated 5 out of 5 by from This stuff ROCKS I used 3 boxes of this stuff building all of the walls in our new backyard landscape. Easy to work with and holds up great. I even used it to stick the decorative birds to blocks to keep them from tipping over. You can pickup the whole thing by grabbing the legs of the bird. Fantastic product. Just be sure to keep a big screw handy to plug the end between uses.

Rated 2 out of 5 by from Not Worth Using I used this product on a retaining wall that is only two blocks in height. (A garden) After 2 years, 50% of the second level blocks were loose. All blocks were clean when I created the wall as the dirt had not been poured in yet. I had to reinstall the blocks with PL Premium 10 fl. oz. Advanced Polyurethane Construction Adhesive. That seemed to do the trick. If you are planning on creating a block stack in any way, I would go with something that has better quality, or you will be redoing your project again in a short amount of time.

Rated 5 out of 5 by from Worked well on a stacked wall. Good adhesion once cured in concrete landscaping blocks. Ample time to move blocks of needed before it cured. I applied it to about six blocks at a time. Will purchase again for future projects.

Rated 5 out of 5 by from Bonds like a rock! Built a rumble stone freestanding wall (and a small garden retaining wall) and this adhesive did the job very well -- everyone loves sitting on the walls and each block is very secure. I've used other Loctite products from super glue to other construction adhesives and so far I am very impressed.
