Description
Lockscape rock glue is a clear-drying, non-toxic adhesive for rocks & pebbles that locks loose gravel and landscape stone exactly where you put them, while still letting water drain naturally. No puddles, no suffocated soil, just stable rocks that stay put.
Two coats of this landscape rock glue create an almost invisible bond against wind, rain, and leaf blowers. Your landscape stays neat without you constantly fixing it.
This easy-to-apply stone glue mixes at a simple 2:1 water ratio and cures in 12-36 hours under dry conditions. Use it on walkways, borders, planting beds, tree rings, and any decorative stone area where rocks won't stop moving.

EVERY CONCERN ANSWERED
Is it safe for pets and kids?
Yes once cured (24–36 hours). Zero VOCs, zero PFAS, NFPA 0/0/0.
Does water drain through?
Yes — 100% permeable. No pooling. No flooding.
How long does it last?
6–24 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 — no shine, no gloss, no plastic coating. The formula creates a flexible mesh between stones, not a film on top.
