PetraMax Mulch Glue for Landscaping Rocks Max Concentrate, Weed Barrier - Non-Toxic Pea Gravel Binder, Mulch & Rock Glue for Landscaping, Landscape Rock & Gravel Stabilizer - Dries Clear (1 Gal)

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.

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.

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!

I used this on landscape gravel between stepping stones in a patio extension. I can't speak to how long it lasts, but it has held up well to initial sweeping with a broom and a subsequent cleaning with a leaf blower. The gravel did darken and take on a little shine, but the convenience of being able to clean the area without worrying about displacing the gravel is worth a little change in appearance.

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 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.

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.
