PetraMax 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)

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.

It is takimg a lot of glue to complete our project, however we are pleased with the outcome so far. The product leaves a nice shine on the rocks .We are using medium/large river rocks in a 50 foot long x 1 foot river bed formation which is around 3 rocks thick. So far we have had to use three 32 oz bottles and not all rocks are bonded yet. We are ordering this gallon to hopefully finish the job of gluing all rocks. Going to mix the rocks in a bucket first this time then lay them down instead of just pouring mixture over the ones that did not adhere together. Hopefully that will do the trick.

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.

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.

This area is approximately 2.5" wide. We used black beach buttons for this project and used the glue on the bottom, middle and top of 3 layers and it holds perfectly. Use either straight from the bottle or from a spray bottle

I used Petra Mulch Glue to stop my mulch from blowing away during storms, and it worked better than expected. It was easy to apply with a sprayer, dried clear, and held everything down without making the area look stiff or artificial. A little goes a long way. Highly recommend for anyone tired of re-mulching after every windy day!

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.

Works great but I have two large dogs the constantly walk and run across the pebbles I used this on and it is not strong enough for my situation. If you plan on using this on an area with little to no foot traffic it should work great for you
