Stop the scatter and lock in your landscape with PetraMax Lockscape — the pro-grade mulch glue and rock glue trusted by DIYers who want results that last. This all-in-one landscape adhesive acts as a powerful gravel binder, rock glue, and gravel glue to anchor pea gravel, decorative stone, decomposed granite, wood chips, and rubber mulch — even in high-erosion zones.
Coverage: up to 150 sq. ft. per gallon, per coat, with a formula engineered for 2x the holding power of standard adhesives.
Our 100% ready-to-use, water-based, non-toxic formula is pet-safe, plant-friendly, and dries clear while staying water-permeable for healthy soil. Just pour into your pump sprayer and apply — no mixing, no dilution, no mess.
Lockscape delivers a firm, stable surface that holds up against wind, rain, and erosion for up to 2 years of protection. The UV-stable adhesion resists washout and keeps your landscape locked in place season after season. Plus, the finished surface is leaf blower friendly, so you can clear debris without displacing your materials.
Fast-drying formula achieves a strong hold in 12 to 36 hours depending on sunlight and weather conditions. Works with any standard garden pump sprayer for quick, even application across your entire project area.
