Captive Shot Blasting for Better Line Markings


Captive shot blasting is a wise move when preparing new concrete surfaces for line marking – but many contractors take short cuts and avoid this important stage.  Fortunately, Amazon are one company that appreciate the benefits of captive blasting, as you can see in our recent work at Darlington.

As a trusted car park marking contractor in the UK, Roadgrip Car parks recommend shot blasting because it increases the longevity of car park markings.  If you don’t remove the laitance on new concrete, you’re applying the paint to a weak layer of fine particles and water that have risen to the surface and aren’t fully adhered to the concrete underneath.  By blasting a small amount of the concrete off the top, the paint will adhere to a much stronger surface.

For this project, we only blasted the areas where markings were going to be applied for efficiency and speed.  We then applied a single epoxy paint to the concrete and thermoplastic markings to the tarmac to clearly mark out the staff car park and service yard.

Despite the unpredictable and unseasonably wet and windy weather of the UK’s 2019 summer, we completed line marking works to all of the external areas at the Darlington site.
