Line marking may look simplistic, but it’s serious business. When done right, it creates safer roads, organised carparks, clear pedestrian zones, and smooth warehouse operations. But  when it is done wrong? It can be an eyesore or worse a safety hazard.

At Dolphin Line Marking, we have seen how small mistakes can lead to big problems. From faded carpark lines to faded pedestrian walkways, these issues not only frustrate users but also pose safety risks and legal challenges. So, let us dive into the most common line marking mistakes—and how to avoid them with professional help.

1. Skipping Surface Preparation

The Mistake:
Some of our competitors paint over dirty, oily, or uneven surfaces. The result? The paint flakes, peels, or fades way too soon.

How to Avoid It:
Always clean the surface first—thoroughly. Remove all dirt, grease, and loose debris. For older surfaces, consider using a primer or pressure clean to ensure strong adhesion.

At Dolphin, surface prep is a non-negotiable part of our line marking process.

2. Ignoring the Weather

The Mistake:
Applying paint on a rainy day or in high humidity sounds like a bad idea—because it is. Wet or extreme weather affects how paint dries and sticks.

How to Avoid It:
Always check the forecast. Paint on dry days with mild temperatures and low humidity for best results.

We complete line marking by working with the weather, not against it.

3. Using the Wrong Materials

The Mistake:
Not all paint is created equal. Using indoor paint outdoors (or vice versa) leads to premature wear, especially under traffic or UV exposure.

How to Avoid It:
Use the right paint for the job—weather-resistant, reflective when needed, and certified for road or warehouse use.

We only use Australian Paint Approval Scheme (APAS)-certified materials for long-lasting, high-visibility results.

4. Getting the Dimensions Wrong

The Mistake:
Incorrectly spaced parking bays, too-narrow walkways, or uneven lines? They not only look bad but can cause confusion, congestion, and even legal problems.

How to Avoid It:
Follow official guidelines. Measure twice (or more). Use layout plans and templates.

We know the regulations and standards and stick to them.

5. Forgetting Accessibility Needs

The Mistake:
Not including accessible spaces, ramps, or proper signage isn’t just non-compliant, it’s unfair to users who rely on them.

How to Avoid It:
Follow Australian standards like AS 2890 and AS 1742. Make sure your space is inclusive and user-friendly.

We take accessibility and accessibility regulations seriously.

6. Inconsistent Marking or Faded Lines

The Mistake:
Uneven lines, mismatched widths, or fading markings create confusion and ruin the professional look of your space.

How to Avoid It:
Use stencils, templates, and skilled line markers. Schedule regular maintenance or touch-ups when needed.

Our line marking is sharp, clean, and durable.

7. Poor Planning and No Future Proofing

The Mistake:
Not planning for future growth—like more traffic or expanding warehouse zones—can cause problems down the road.

How to Avoid It:
Plan ahead. Design with flexibility in mind so changes can be made without starting from scratch.

We help our clients plan smart line marking that improve safety and organisation.
