Petra Max Rock Glue for Landscaping, 32 Ounce - Ground Coverage & Pet Safe Mulch Glue for Rocks - Lockdown Gravel/Pebbles/Stones - Sticky Clear Gravel Binder & Decomposed Granite Stabilizer (50 Sq Ft)

I just redid my side yard and had gravel put in around the walkway. The loose rocks drove me crazy so I purchased gravel glue - two 32 ounce bottles, along with the applicator. The first time, I screwed up the mix ratio and watered it down. The second bottle, followed the directions on the back and applied it correctly (I think) using their applicator, which I love!I Waited for it to cure and it held and it held well. I was happy. Then we were inundated with rain that lasted for three days. The glue held really well in the large sections of gravel, but not other sections - particularly between the pavers. It was as if I didn’t apply the glue at all. I didn’t understand what I did wrong as I had applied it evenly throughout. I knew that the application needed to be fixed/adjusted, and likely due drainage and moisture.I messaged the company with my questions. After sending them pictures, explaining the water to glue ratio I used, they recommended that, due to the heavy rain we’ve been getting, I try a 1:1 ratio, and apply 2-3 coats. I am going to do that when we are not expecting rain for a day or two. It’ll work - not concerned. Again, it held up in other sections, just not all.As for the glue - here’s a picture following my second application. I do like that it has a color to it when you apply it, but dries clear. The gravel against the house - large sections believe it or not - are the sections that held and the glue is still intact. With the exception of the gutters, there’s no overhang that gives that section shelter - so not sure why there it held, and not everywhere else. Again, I suspect drainage or moisture that may have existed before I applied, but that’s a guess.I would just make sure the area is completely dry, no rain expected for a couple of days, and if you live in an area that is experiencing a lot of rain, thicken the glue and apply 3 coats. Of course, you can always reach out to the company with any questions, and ask for guidance before you start the process. They are responsive and extremely helpful. Also, get their applicator! It’s easy to use and makes the application easier allowing you to evenly distribute it throughout sections.But I do want to give a shoutout to the Petra! I appreciated their responsiveness and their willingness to walk me through the steps, and come up with an alternative solution. A company that is willing to do that, without issue, is a good company to stand behind and support. I will definitely be a repeat customer.

So far 5 stars. We sprayed 2 generous coats on from each side, back to back. It was a hot 92* day sap they dried to touch in about 2-3 hours. Pretty amazing so far. Love that its tinted blue so easy to see where it’s going and where you’ve missed. Rocks are shiny & most feel stuck together. Will do one more coat in 2 days. Main reason we are trying this product, is to make leaf removal easier, and to keep the rock that are sloped up in place. There will be little to no foot traffic. Will update review in about 2 months after we’re dead in the middle of our intense summer.

To me, it is well worth the expense. I ordered two more bottles, I've only just started the landscaping work. If I'm going to take the time, expense, and sweat equity to remove old messy rock and replace with a new weed barrier and fresh mulch, I want it to stay clean and neat. This glue did the job very well. Allow the fresh mulch to dry before applying the glue, waiting a day or two after you put down the mulch before you apply the glue. A thin layer won't cut it if you have 3 inches of new mulch. I applied it heavily, letting it soak in, then reapplied again. Take your time applying it and do it correctly. A few days ago I mowed, then took the blower to blow away the grass clippings that landed in the new mulch. The glue held the mulch excellently, and I easily identified areas where I didn't apply enough glue and the mulch moved. I'm very pleased with this product. Be sure to follow the directions, take your time, and apply heavily, or you will likely be disappointed.

I have used this glue to hold down pea gravel to prevent my puppy from ingesting. It is super easy to apply with a sprayer. Just mix with water ( little goes a long way) Secure gravel ( I used a tamper to flatten the gravel) and start spraying. The glue has a purple hue when applied so you can easily see where you applied it. It will dry clear. I secured the gravel with one application but because the area will get walked on, I plan on applying additional application. Overall, so far very happy with the glue and recommend for land scaping projects- bonus it is PET SAFE

Did real well. Locked in the rock I needed locked in. You need to use more if it’s bigger than pebble style. But still works well

I have used this in various place in my yard to hold small-med size rocks in place. (1/2"-3"). It rains a lot here. So I now mostly use it for touch ups and in high traffic areas. So happy someone told me about this product.

Its OK. The glue isn't as strong when I mixed the required recommendations and did two wet coats. I waited more than 3 days for the "cure" to be the best and (without rain weather) I still had a handful of the top rocks pretty loose. If I had to compare, it would be equivalent to a bottle of diluted Elmer's glue. It may be better suited for smaller pebbles versus my 2 inch sized rocks.

This mulch glue which I put down yesterday, appears to do the job. The one major drawback is the fact that it does not go a long way especially if you spray all of your mulch. I use 12 yards of mulch in my landscape so I only did around the edges and places where water washes away the mulch. I barely finished one coat for my front yard. Now need to order another to work on my backyard in the same manner. Doing 2 coats will take me broke.
