A Traditional and Effective Removal Method
When it comes to removing old, stubborn road markings, sometimes you just need to bring the heat. While modern technologies like water jetting are fantastic for certain applications, there are times when burning off old paint with a thermal lance is the most practical, cost-effective, and efficient way to clear a surface. If you are redesigning a car park in Bromborough or altering a junction in Birkenhead, getting rid of the old thermoplastic lines quickly is essential before the new layout can be applied.
As part of our comprehensive Quick and Clean Line Removal Services in the Wirral, Shawfield Line Marking frequently utilises thermal lancing. It is a tried-and-tested method that, when handled by experienced professionals, yields excellent results with minimal fuss.
How a Thermal Lance Works
A thermal lance is a powerful piece of equipment that mixes compressed air with propane gas to create an incredibly hot, high-velocity flame. This flame is directed precisely onto the old road marking. Because the vast majority of UK road lines are made from thermoplastic—a material that is melted onto the road in the first place—applying extreme heat causes the material to instantly superheat and vaporise, or turn to a dry ash that can be easily swept away.
This method is entirely different from Using Hydroblasting to Remove Old Road Lines, which uses water pressure. The thermal lance literally burns the paint off the tarmac. It is particularly effective for thick, built-up layers of thermoplastic that have been painted over multiple times over the years.
When is Thermal Lancing the Best Choice?
Thermal lancing is highly portable and doesn’t require the massive water tanks or heavy lorry-mounted rigs associated with hydroblasting. This makes it the perfect choice for smaller jobs, tight spaces, or areas with restricted access. If you have a few redundant disabled bays in a small Wirral car park, or a short stretch of double yellow lines that need erasing, a thermal lance is quick to set up and gets the job done fast.
It is also an excellent tool for drying out the road surface. If you are wondering When Is It Time to Repaint Your Faded Lines?, you’ll know that painting on a wet surface is a recipe for failure. The intense heat of the thermal lance not only removes the old paint but leaves the tarmac bone dry and warm, creating the perfect conditions for the immediate application of new thermoplastic lines.
Safety and Surface Care
Because a thermal lance generates temperatures in excess of 1000°C, it must be operated by highly trained professionals. In the wrong hands, the intense heat can melt the bitumen in the tarmac, causing the road surface to degrade and potentially leading to a situation where you are Fixing Potholes Before We Paint New Lines. Our operatives at Shawfield Line Marking keep the lance moving at a precise speed, ensuring the paint is destroyed without damaging the structural integrity of the road beneath.
It is also worth noting that thermal lancing is generally best suited for tarmac and asphalt surfaces. Applying this level of heat to concrete can cause it to spall or crack, so we will always assess your specific surface before recommending the best removal method.
