When it comes to refreshing a site, many businesses and property managers ask: “Do old line markings need to be removed completely, or can they just be painted over?”

At C&R Ltd, we’re often called to sites where existing markings are faded, outdated, or incorrect. In this blog, we’ll explain whether painting over old markings is a good idea, the risks involved, and the best approach for long-lasting results.

The Quick Answer

Yes, in some cases line markings can be painted over. However, it’s not always the best solution. If the existing lines are raised, cracked, or peeling, painting over them can create an uneven, unclear finish that doesn’t last.

For high-traffic areas — such as car parks, warehouses, and roads — full removal or proper preparation is usually the best option.

When Painting Over Might Work

Painting over existing markings may be possible if:

• The old lines are flat, stable, and not peeling.
• The new layout matches the old one closely.
• The surface has been thoroughly cleaned and prepared.

This approach is sometimes used for quick refreshes in low-traffic environments, but it should be considered a short-term solution.

When Removal Is the Better Choice

For most professional applications, removing old markings first provides a much cleaner, safer, and longer-lasting result. At C&R Ltd, we use methods such as:

• Hydroblasting to remove markings without damaging the surface.
• Shot blasting or grinding for stubborn paint or thermoplastic.
• Chemical removal in select cases.

This ensures the surface is smooth and ready for crisp, durable new markings.

Risks of Simply Painting Over

Skipping removal can lead to:

• Poor adhesion, with new paint flaking away quickly.
• Confusing double lines if old markings remain visible.
• A messy, unprofessional appearance.
• Higher long-term costs if rework is needed sooner.

That’s why we always recommend removal for safety-critical markings, such as road lines, pedestrian crossings, or warehouse safety zones.
