After 50 years of marking out construction sites, retaining wall footings, excavation trenches, and survey pegs across Australia, one thing is clear: a reliable marking paint saves time, prevents costly mistakes, and keeps crews safe. The Dy-Mark Spray & Mark 350g is the can we reach for on every job — from concrete sleeper wall set-outs in Brisbane clay to rocky ground pegging on Sydney sandstone sites.
The 360° inverted valve is the standout feature for trade use. You can mark directly onto the ground without crouching or repositioning — just point and spray. The toluene-free formula reduces fumes during repeat passes, which matters when you're marking 200 pegs in a row or working in a confined drainage trench.
One 350g can delivers 200+ spot marks or up to 120 linear metres of line depending on surface and colour. It dries to touch in approximately 5 minutes at 25°C and remains legible outdoors for up to 3 months — long enough to cover the full construction phase of most retaining wall and civil projects.
Suitable for use on concrete, bitumen, compacted gravel, rock, steel, timber, and general broken ground. Performs on both smooth and rough surfaces — ideal for the varied conditions found on Australian construction and civil sites. Compliant with standard site safety colour-coding practices referenced in Safe Work Australia guidelines.

When setting out retaining walls in Australia, post-hole and footing positions must be accurately marked before excavation. Walls over 1 metre in height are subject to engineering requirements under AS 4678-2002 Earth-Retaining Structures. Accurate site marking from the outset reduces the risk of footing misalignment and costly rework. Check your local council requirements — most Australian states require a building permit for retaining walls over 1 metre, including QBCC (Queensland), VBA (Victoria), and WA Building and Energy.
