Dilute Landscape Lock concentrate with water in a garden sprayer or watering can — rates from 1:3 to 1:6 depending on your surface.
Spray the area until completely saturated. Rinse any overspray off hard surfaces before it dries.
Leave to cure for 24–72 hours, protected from rain and irrigation. Then enjoy a locked-down landscape for up to 12 months.

Watch how Landscape Lock is applied to mulch and pebbles.
Set-and-forget protection for the surfaces you've worked hard on.
Landscape Lock is stocked nationally at Bunnings Warehouse and selected independent stockists.
One application holds your mulch or pebbles in place for up to 12 months, depending on surface, traffic and weather exposure. Simply re-apply when you top up your mulch.
No. The cured film is water permeable — rain and irrigation pass straight through to the soil beneath.
Yes — that's the point! Treated mulch and pebbles stay put, so you can blow leaves and debris off without redistributing your landscaping.
Use our coverage calculator. As a guide, 1L of concentrate covers 5–24 m² of mulch depending on the type. Landscape Lock comes in 2L, 5L and 20L bottles.
Wet surrounding hard surfaces before you start and rinse off any overspray immediately — don't let it dry. Once cured it's difficult to remove from porous surfaces.
