Petra Max Rock Glue for Landscaping, 1 Gallon Concentrate

My wife and our eldest son did all the work, it applied with little difficulty. Due to health issues, I was limited on what I could do. The application wasn't exact per instructions, it went down well and 7 days later it looked good and when we blew the wind debris it came off easily. It dried a little less than stated time and did not puddle up with the rain (1") overnight. It never felt sticky, the grandkids tested, with our puppy, the finished product and it held well. Our tamper is a McCloud tool, very universal, actually mostly used as a wildfire tool.

We have a lot of areas with 1/4-1/2 inch gravel stone that our dog loves to dig up. She does not do that anymore. It takes several coats, but this stuff works very well. As an added bonus, I like that it dries in such a way that it leaves the stones with a shiny wet look. It seems to take about a half day to dry one coat. Maybe faster if it’s hot or you have full sun. Go in knowing that this is not going to work with a single coat. I think I used 4-5 coats. It’s quite difficult to pry the stones up now. When it rains, the glue does liquify again. I would imagine in time it will degrade, but we’ll see.

So I used this in multiple places. One is around paver's we walk on where sometimes people step on them. In this area I followed instructions and while spraying the sprayer constantly clogged. We are talking 10min total in time. The amount needed for even a small area is crazy but I started with a small area. After the first day they were hard to the touch and seemed to work. However on day 2 I tested a small spot and stepped on them. They were tacky and stick to the bottom of your shoes / feet and clusters of stones pulled up. I gave the rest another 2 days to dry and it’s a hotter day today. Just went out and it’s almost like the glue is softer and no longer hard. All they just pull up in sticky clusters. I now have an area where all the stones have a tacky sticking shiny finish and stick to everything. So instead of stones just being kicked and you happen to walk on them, now they stick to your feet and shoes and stay on the bottom which is worse. At this point we will probably have to rake up all the stones and replace them as it’s just a mess now. The other area I mentioned is just a flower bed so it doesn’t matter that they are sticky. But also I have no reason to use it there as no one moves those rocks so more of a pointless use case. This stuff is basically Elmer’s glue that doesn’t like heat.

It works but I would need more coats and it feels like it won’t last more than a year. Not rock solid like I was hoping.

I bought another glue in another place and didn’t work even with more than one application, however, this one worked perfectly. It was really easy to apply, it dried fast and the rocks in backyard have been stick to the grass for more than 2 months without any problem.

*updated - Seller promptly addressed my issues with the product. Original Review - I used three bottles, coated pea gravel using a sprayer, mixed to required amounts. Applied it to dry clean gravel. The gravel still moves after spraying, so no hold as expected with this product. I'm disappointed in that you can't see results until you use the product. After use, it isn't returnable. Contacting manufacturer to see if there are other options. Extremely disappointed and would not buy again. Manufacturer wanted photos, so I took some and sent them to them. Thought they were worth a view here too. The gravel is as lose as it was before application.

This works really well you definitely need two applications the first time but once applied the stones are good and stuck. Even heavy rainstorms do not move the small pea pebbles. It has been about 4 months since I applied and still going strong. The stones also look like they were rained on even after 4 months of the hot southern sun.

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.
