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.

This product works great. I highly recommend it. Just make sure whatever area you’re spraying is clean. Wash it with water before hand. Let it dry thoroughly, follow the directions and mix the adhesive with the water per the instructions. This was a 40 x 3 foot path. spray your first coat. Let it dry for two days at least that’s what I did then spray your second coat. I have seen some comments in the reviews about the sprayer not being any good. I already have another yard sprayer that I use for different items, but I think this was worth getting the one that came in the kit because it has the correct nozzles. The only thing you have to remember is that immediately after you’re done you have to take it apart and clean it thoroughly with water Keep in mind. This is an adhesive if you don’t clean it it’ll dry and stick to everything and clog your sprayer! Clean it out and let it dry and you won’t have any problems. I am a backyard do it yourself guy and I found this product to be really great and worth the money. I can’t speak to durability yet as it’s only been on for a few days.

. Update: I m changing my review to a 4 star. Even though the product didn't work for me, the seller reached out to me and offered a full refund even though I never asked for one. That alone will bring me back as a customer.

Its great if you follow directions but... I used half rock glue and half water for my display because thats what worked best. Had a summer display for about 6 months. Will redo in spring

Wasn’t really worth it. I have a couple pathways with pea gravel and stepping stones. I mixed the glue and applied 5-6 coats to the stones and then waited till the next day, the pea gravel were barely stuck together. They easily came apart just by running your hand over them. I had no delusion that they would hold up to everyday walking but they became separated after taking the first step on them. Perhaps if I mixed the gravel in the glue and spread it out like concrete it would work better but the amount of glue I would need to get would cost a fortune. It wasn’t really worth the money for me.

As a backyard lover and gardener, I’m thrilled with the Petra Max Rock Glue for Landscaping! It’s an absolute game-changer for keeping my rock beds, gravel paths, and decorative stones exactly where I want them. The adhesion is incredibly strong, locking everything in place even after heavy rain or wind. The thickness of the glue is just right — not runny or messy — and it spreads evenly for clean, professional-looking results. The color dries perfectly clear, leaving a natural appearance that enhances my garden’s look instead of dulling it. It dries quickly, too, which is a huge plus when working outdoors — I was able to finish an entire section in one afternoon without waiting around. Once cured, the appearance is flawless, giving the rocks a slightly polished look without making them shiny. I’m also impressed by the durability — it’s tough enough to withstand all kinds of weather while keeping everything securely in place season after season. It’s also pet-safe, which gives me peace of mind while my dogs roam the yard. Overall, this glue is strong, clear, fast-drying, and long-lasting — exactly what every gardener dreams of. If you want your landscaping to look neat, clean, and stay put, this is the product to get. Five stars all the way! 🌸💪

Works exactly as described! Easy to use, instructions included, goes along way, easy to mix & affordable.

This glue fulfills its function and has good adhesion for landscaping work and decoration with stones. I used it to fix rocks and, once dry, it stands firm. However, drying is not as fast as expected and it is important to apply it carefully to avoid excess product.

Product delivered exaclty what I need to keep the mulch from blowing around!

Whole bottle was clumpy and unusable Waste of money

This product hardened in the container prior To opening. Once likened could not use. Would appreciate solution. Item was stored properly. NOTE: the company was very accommodating to fix the issue and did so. Very please w the customer service and sense of urgency.

This product came delivered hard and unusable, by the time I went to use it it was too late to return, very disappointed as I wish I would have opened it right away but due to weather I didn’t want to have the product go to waste. Only to find out it was already garbage

Once it’s hardened it works pretty good but don’t sweep it or hit it with a hose. It washes away. I clean the path with my shop vacuum now.
