EcoLock HD 2 Gallon Mulch & Rock Glue for Landscaping - Ready-to-Use Fast-Drying Formula

The Pro-Size Landscape Adhesive — Best Value

EcoLock HD 2 Gallon is our best-value size for homeowners with larger yards and professionals managing multiple properties. The same trusted formula that keeps mulch, rock, and gravel locked in place for up to 24 months — now with enough coverage to handle your biggest projects in a single container.

The 2 Gallon saves you roughly 10% per gallon versus buying two 1-gallon jugs — and saves you trips to the store. Ready to use straight from the jug: pour into a pump sprayer and go.

Why Landscapers Choose the 2 Gallon

• Save ~10% per gallon — better per-gallon price than buying two 1-gallon jugs.
• Up to ~390 sq ft on mulch & bark — enough for most residential front and back yard beds.
• Ready to use — no mixing, no diluting. Pour and spray.
• Professional results — the same formula used by commercial landscapers and property managers.
• One container, one project — handle the whole job without running out mid-application.

Works On All Landscaping Materials

EcoLock HD bonds to virtually any loose landscaping material: hardwood mulch, cedar mulch, cypress mulch, dyed mulch, rubber mulch, pea gravel, river rock, decorative stone, crushed granite, lava rock, and ground cover chips. It dries clear and won't change the appearance of your landscaping.

Coverage

2 gallons covers approximately:

• Up to ~390 sq ft on mulch / bark
• Up to ~300 sq ft on pine straw
• Up to ~200 sq ft on rock / gravel

Coverage varies with material porosity, depth, and number of coats. For slopes and high-traffic areas, apply a heavier coat for extra hold.

How to Apply

1. Prepare — Ensure your mulch or rock bed is dry, clean, and settled at your desired depth (2–3 inches recommended for mulch).
2. Pour — Transfer EcoLock HD into a standard pump sprayer. No mixing or diluting needed.
3. Spray — Apply an even coat across the entire surface. Use a heavier coat on slopes, rock, and high-traffic areas.
4. Dry — Allow 2–4 hours to set. Full cure in 24 hours. Avoid foot traffic and water during drying.
5. Reapply as needed — For maximum durability, reapply every 12–24 months or after heavy disturbance.
