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.

Customer Reviews
Easy to use and very satisfied!
This was good. Honestly I was skeptical that it would work but it does. It only really get the very top layer for pea gravel so you'll need to kinda stir it so it makes it way down. But yep... it's impressive
Great product. Easy to use. Early on to give evaluation of product as to efficacy over a long period. Applied to pea gravel around flagstones. Looks great at this point, must wait and see long term effects.!
I’m shocked! I honestly didnt think it would work but had hopes and PetraMax really surpised me. It works great. We have a gravel walkway path and barkdust in the sides. I hares when the rock and bark would mix so we wanted something to keep the rock in place as well as easy to blow off and this Rock Glue did not disappoint! Super happy with it and recomend it to everyone.
EVERY CONCERN ANSWERED
Will it actually hold pea gravel & round stones?
Yes. RTU rock glue max is specifically formulated for decorative landscape stones, including pea gravel, river rock, lava rock, small pebbles & decomposed granite ranging from 1/4 inch to 1/2 inch in diameter.
How long does it last?
When applied correctly to clean, dry stone, RTU Rock Glue Max can last up to one year. In areas with harsher weather or stronger exposure, a light touch-up may be needed sooner, typically every 6 to 12 months.
Does it dry clear?
Yes. The formula dries clear with a slight shine and does not leave behind white residue, cloudiness, or a heavy artificial coating. Once fully cured, it keeps the natural look of your stone surface intact.
Is it water-permeable, and will it affect drainage?
No, it will not interfere with drainage. RTU Rock Glue Max forms a 100% water-permeable bond, allowing rain and irrigation to pass through the treated surface into the soil below while helping maintain natural moisture flow.
Is it safe for pets, kids, plants, and soil?
Yes. This non-toxic, VOC-free formula is safe for pets & kids once it's fully dried. It is plant-safe and does not harm roots or interfere with the soil underneath when used as directed.
Will it clog my sprayer?
No. RTU Rock Glue Max is designed for use in a standard garden sprayer. For best results, use PetraTools 1 Gallon Garden Sprayer. Simply shake well, pour into your sprayer using a strainer, apply evenly, and rinse the sprayer thoroughly with clean water after use.
What surface prep is required, and how many coats should I apply?
For best results, start with clean, dry stones free of loose dirt and debris. Apply one even coat, lightly rake and turn the surface, then apply a second coat and tamp down. Let it cure for 24 hours for a cleaner, more secure finish.
How long does it take to dry?
RTU Rock Glue Max typically cures in 24 hours under dry conditions. Cooler temperatures, high humidity, or shaded areas may extend cure time slightly, so apply only when the forecast allows enough dry time after application.
Does it work on slopes and high-traffic areas?
It performs well on slopes, garden borders, tree rings, planting beds, and other decorative landscape areas. It is not intended for driveways or surfaces exposed to vehicles or heavy, frequent foot traffic.
