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 love this stuff. You can use it for more than just mulch. I used it on rocks I have decorated our drains in our yard. Very good quality and holds them in place.

Have the area around my standby generator slab that needed some landscaping touches, so I put some decomposed granite around it and made the area look pretty. Of course, Mother Nature had other plans after some rainstorms this Spring where the stone stayed in place, but the area had shifted and pock-marked from the rain. Already had the Petra 2-gallon sprayer so I got a small container of their rock glue, smoothed out an area with a concrete trowel and applied this product. Was I really surprised and impressed with the results! Not only has the treated area held up from the onslaught of rain and weather, but I was also really impressed with the quality of adhesion and hold when dry and the lack of "erosion" to that area. Will definitely get a larger container of the glue and complete the job but also have some left over to spot-apply where needed. As with anything that is left outside to the elements, reapplication to the entire area will be called for on possibly a yearly basis to maintain the looks and integrity of the granite landscaping.

I rarely leave reviews, but I’m so disappointed I had to say something. This landscape rock glue did absolutely nothing. I followed the instructions exactly and even made the second batch less diluted to try to get better results—still no difference. The rocks are just as loose as they were before applying it. For the price, I expected some improvement, but this was a total waste. Save your money—this product does not work.

So far this is a great product. It was very easy to apply. I really like the look. I put the pebbles in a bucket, and poured just enough to cover all then hand mixed and applied with a trowel. It was sticky enough so the pebbles stayed in place. The only reason I gave it 4 stars is I don’t know how long it will last and how it will look over time. For now it looks great and I love it but time will tell the quality of the product.

Delivery was super fast, and the product was easy to spray on. It dries really quick and stones are solid. The stones did turn a little darker (as if they were washed and the dust came off them) but they look even nicer against the pavers. Make sure you wash you sprayer straight away!

This is a great product to keep your gravel or pebbles from spreading around your yard, driveway, whatever. However, it does not work very well on natural mulch. I have a small area, maybe 10 by 12 feet in size that I filled with natural mulch (not rubber). After four applications, I still do not see any results. Also, bear in mind that if you are using a sprayer, this adhesive will clog your sprayer, and a clean up is a bit messy. This would be so much better if a) it would actually work on mulch, and b) came with its own applicator/sprayer.

Ok this is a game changer for people with large dogs. I have an area of my yard that can’t grow grass because of shade. I’ve created a rock walkway with mulch around it. Normally my dogs run through it and mulch and pea gravel flies everywhere. In a matter of a week it’s a giant mess. I used this on the mulch and pea gravel. My dogs run through it and everything stays in place. Simply amazing!!!

Did not perform as I expected. Did not keep mulch from moving. It was pricey & I would not use again
