Why I'm Keeping This in Rotation
Zero Toxins.
Kids running around. Dog out back. Zero VOCs. Zero PFAS. Plant-friendly. Pet safe, kid safe once cured. Green light from me.
Rain Drains Right Through
Watched the mulch stay put through a storm. Water still drained. Not a puddle in sight.
Apply Once. Forget About It.
One application. 12â24 months of hold. That's a hack that actually works.
Made in the USA. Not Imported.
Made in Carlisle, Pennsylvania. Tested at Mid South Lab. Not just a viral find â actually backed up.
How I Did It (Quick Version)
Clean it. Spray it. Forget it. That's the whole process.
Step 1
Clean Your Surface.
Mulch how you want it. Dry. No leaves.
Step 2
Spray Two Coats.
Two coats with the Ready-to-Use sprayer it comes with. About 20 minutes.
Step 3
Cure & Enjoy.
Let it cure overnight. By tomorrow it's locked in.

Customer Reviews
Havenât used the max that mix with water but have used the ready to spray and it works ok so far
Steve
After three coats (add one more coat because of area) it's holding up and looks pretty good! Hopefully it will last at least eight or more months. Plan on buying more very soon. It's easy to use and clean. I have the Sprayer , Awesome.
The instructions are pretty clear. It took me a week to get started. This morning I just finishe a 3rd coat. A couple arear fairly thick pea gravel so I went over it again. Hopefully that did the trick
The glue definitely does work and holds the stones together very well.
Easy to work with, great stuff
EVERY CONCERN ANSWERED
Is it safe for pets and kids?
Yes once cured (24â36 hours). Zero VOCs, zero PFAS, NFPA 0/0/0.
Does water drain through?
Yes â 100% permeable. No pooling. No flooding.
How long does it last?
6â24 months. Touch up spray once a year for best results.
Does it stop weeds?
Reduces weed growth but isn't a herbicide. Pair with weed barrier fabric.
Will Rock Glue make my rock look shiny or plastic?
No. Rock Glue Max dries clear with an invisible finish. Your rock looks exactly the same as before â no shine, no gloss, no plastic coating. The formula creates a flexible mesh between stones, not a film on top.
