Fresh mulch looks great for a few days then wind, rain, and foot traffic start moving it everywhere.

How to Apply EcoLock HD

Three simple steps

  • Step 1 - Spray first coat of EcoLock HD mulch glue evenly over landscape material

    Step 1 — Spray Coat 1

    Using a standard garden pump sprayer, apply a light, even coat over dry material. Do not oversaturate.

  • Step 2 - Rake or turn mulch to expose uncoated surfaces

    Step 2 — Rake or Turn

    Lightly rake or turn the top layer so uncoated material underneath is exposed. This helps improve overall coverage.

  • Step 3 - Spray second coat of EcoLock HD for long-lasting hold

    Step 3 — Spray Coat 2

    Apply a second coat of EcoLock HD over the turned material. Allow 24 hours to fully cure. The adhesive dries clear and holds for up to 24 months.

    For best results: Apply to dry material. Use thin, even coats. Avoid oversaturation. Clean tools promptly after use.

EcoLock HD Landscape Adhesive — Professional Mulch & Rock Glue

From the Team Behind Craft Resin

We’ve spent years formulating specialty products at Craft Resin — trusted by crafters in 30+ countries.

EcoLock HD started as a personal frustration. We were tired of watching mulch scatter across driveways after every storm, and gravel creep out of pathways week after week. So we did what we do best: we went to the lab.

Our team combines US-based product development with advanced polymer chemistry and real-world testing. The result is a water-based formula engineered to penetrate, bond, and stabilize — not just sit on top.

Same commitment to quality. Same attention to formulation science. Now applied to your landscape.
