This month’s article with Three Counties Lining will be covering the most frequently asked questions about road markings. Whether you want to know what’s environmentally friendly, how long markings last and whether they’re reversible – we have it all here for you and more!

Is it possible to remove old road markings?

It is indeed possible to remove old road markings – it’s a very important part of what we do. Although lines are supposed to be durable to last for years and removal can be quite difficult, we do have a number of processes that remove these tough lines effectively. There are four ways to remove markings, there’s hydroblasting, grinding, abrasive blasting and compressed gas. All road marking removal can be done in rain or shine.

Hydroblasting – is an environmentally friendly, chemical free method where water is blasted at a extremely high pressure, in order to lift up the markings. However, this process doesn’t work on materials like epoxy and thermoplastic.

Grinding – this requires a specific grinding machine with sharp teeth that abolish the thermoplastic lines bonded tightly to the road. Although because grinding can be an aggressive way of removal, sometimes this can cause damage to the road surface.

Abrasive Blasting – this procedure utilises sand or steel particles at an extremely high pressure in order to remove old markings.

Compressed Gas – uses propane gas with compressed air. These combined elements burn through tough markings. This is one of the most expensive removal processes.

Although, coverage isn’t always the right way to go, sometimes black paint is used to hide road markings. You may be surprised but this can last around 4-5 years, of course this is only temporary and will need repeat applications in years to come. On the roads it’s a must that this is kept on top of.

How long do road markings last?

This all depends on whether it’s paint or thermoplastic but generally they can last for many years.

How long does it take for the paint to dry?

Thermoplastic dries quickly, usually taking one minute to solidify. Road paint can take up to 2 hours.

How quickly can you drive on the new road markings?

You can drive on thermoplastic minutes after application – for paint it can be longer and depends on environmental factors (e.g if it’s sunny it’ll dry much quicker than a dull, humid day).

Can you apply line markings when it’s raining?

When it rains, it’s common knowledge amongst drivers that you must slow down, this is because the tyres lose grip of the road as friction is reduced. Just like cars, the road markings perform better in drier conditions, as it creates a better, stronger bond between the materials.

What is road paint made of?

Paint contains: binders or resins, pigments, and water or solvents – and in special cases paint can contain retroreflective glass beads to mark particularly important signs.
