Loose stone has a way of turning a finished landscape into a weekend cleanup project. After rain, gravel shifts out of place, borders spread into the lawn, weeds start showing through, and neat edges around tree rings and beds begin to disappear. PetraMax Lockscape Rock Glue makes that job much easier with a ready-to-spray formula that skips the usual hassle. No mixing, no measuring, no complicated prep. Just pour it into your sprayer and apply. It is a simple way to help keep pea gravel and decorative stone in place in trouble spots, while also helping reduce weed growth between stones. It is best for decorative areas and low-traffic spaces where you want a cleaner, more controlled look without constantly fixing the same mess.

Store tightly sealed at room temperature, away from direct sunlight and freezing temperatures. Never pour unused product into drains, storm sewers, or waterways. Dispose of empty, dried containers following your local plastic waste guidelines.

Frequently Asked Questions

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.
