We need to remove old line markings on roads, highways, freeways, and car parks because paint fades over time and needs to be replaced. For variety of reasons, lanes on roads and freeways need realigning, temporary markings need to be removed, and spots in car parks need to be rearranged to optimise parking.
To apply new lines, you have to remove the old lines first, which means you need to hire a professional line removal service. Line markings must be removed so that they do not cause confusion among road users, meaning that whatever method is used to remove them, the markings must no longer be recognisable after removal.
The old paint material must also be contained in an environmentally acceptable manner and removed and disposed of safely. Having said that, there is no single method of removing line painting that works for every situation. Depending on the circumstances, situation and the desired result, the following removal methods can be implemented:
1. Surface Grinding
Prior to applying new lines to concrete, we remove the old line painting by using a dust-free concrete grinding method that can be applied on the surface both internally and externally. At first, there will still be some slight contrast between the old and new lines, but we then blast them with water, which makes the old lines hardly noticeable, and whatever slight contrast remains will fade over time.
2. Water Blasting
Water blasting is a messy method and it requires a lot of cleaning up afterwards. This also needs to wait for the surface to dry for two days before repainting the lines. It is very effective at removing old line markings from contoured surfaces, as well as concrete surfaces inside multi-story car parks.
