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.

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

We used this product on a small walkway with pavers and small decorative rocks. We followed the instructions carefully, which were actually clearer than many of the other products we considered, so we had high hopes. Unfortunately, the adhesive didn’t perform as expected for our project, and the rocks didn’t hold in place. We eventually ordered a different product with a thicker consistency that worked better for our needs. This product may still work for other applications, but it wasn’t the right fit for ours.

Very clever idea works good a little pricey, but it keeps the birds from hauling off my little blue rocks

This turned a pretty solid outdoor walking path into focal point. We had large pavers with small gravel to fill in between over sand. With how much foilage we get in the backyard we didn't want the gravel spreading far while we use our leaf blower. Once the glue dries it made the rocks look more permanently wet with much more color. I like it so much I will buy some more and spray some bigger river rock less for the hold and more for the color. It's two months of rain and leaf blowing and they stick together really well. Obviously as I walk on it some parts become unstuck. I may need to spray again in two years

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.
