Marking Paint

Marking paint and site marker sprays used by builders, concreters, surveyors, and retaining wall installers across Australia. With over 50 years of hands-on construction experience, we stock the professional-grade marking products that tradies actually use on site — not hardware store alternatives that fade after one rain event.

Whether you're marking out post hole positions for a concrete sleeper retaining wall, setting out survey pegs, or marking underground service locations before excavation, the right marking paint makes the difference between a clean job and a costly mistake.

What Is Marking Paint Used For on Construction Sites?

• Post hole and footing layout — mark H-beam post positions before drilling or excavating
• Retaining wall set-out — mark wall alignment, batter, and step positions on site
• Underground service marking — identify gas, water, electrical, and comms locations before digging (follow Dial Before You Dig requirements)
• Survey and boundary marking — temporary line marking for site surveys and setout
• Concrete and asphalt marking — mark cut lines, joint positions, and reference points on hard surfaces

Why Use Professional Marking Paint?

Professional site marking paints like DY-Mark are formulated to be visible in all weather conditions, resist UV fading, and apply cleanly in inverted (upside-down) spray positions — essential for ground marking. Standard aerosol paints are not designed for this and will clog, fade, or fail to apply correctly on rough surfaces like compacted soil, gravel, or concrete.

Colour Coding for Site Marking

Australian construction sites follow the AS 5488-2013 colour code standard for underground service marking:

• Red — electrical services
• Yellow — gas services
• Blue — water services
• Orange — communications
• Green — sewer and drainage
• White — proposed excavation area
• Pink/Fluoro — temporary survey marks

Always check with your local authority and refer to Dial Before You Dig before any excavation work.
