Sound Familiar?
Fresh mulch looks great for a few days then wind, rain, and foot traffic start moving it everywhere.
Gravel spreads onto paths. Decorative rock shifts. And instead of enjoying your yard, you keep fixing it.
EcoLock HD stops the cycle.

How to Apply EcoLock HD
Three simple steps
-
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
Lightly rake or turn the top layer so uncoated material underneath is exposed. This helps improve overall coverage.
-
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.

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.

What Our Customers Say
Real results from real homeowners
Finally, a mulch glue that works
“I’ve tried three other brands and they all washed away after the first rain. EcoLock HD held through two storms and my mulch beds still look perfect. Worth every penny.”
So easy to apply
“Just poured it into my garden sprayer and went to work. Covered my entire front yard in about 30 minutes. It dried clear and you can’t even tell it’s there. My gravel path hasn’t moved since.”
Great for decorative rock
“We have river rock around our pool area and it was constantly getting kicked around. One application of EcoLock HD and it’s stayed in place for months now. The kids love it too — it’s safe once dry.”
