The marking products are known to be difficult to erase without a trace. However, it is sometimes necessary to delete a mark on the ground, for example in the case of a change of priority, a change of direction or for the deletion of parking spaces where recycled rubber parking blocks might be thought a better alternative. There are several techniques for erasing road paints and floor resins:
- Shot blasting
- Sanding
- Milling
- Hydro-projection
- Masking
- Chemical pickling
- Burning
How To Erase The Marking On The Ground With The Shot Blasting Technique?
Shot blasting is a mechanical process which consists in projecting, using a machine, steel balls by centrifugal force onto the surface. The shot is then recycled into the machine in a closed circuit.
Shot blasting is an environmentally friendly technique that does not use chemicals or potable water.
It is necessary to connect a vacuum cleaner to collect residues and dust. This technique is an alternative to milling. The cost of equipment remains higher, however.
How To Erase The Marking On The Ground By Sanding?
Floor sanders use abrasive discs of different hardness depending on the surface to be sanded. Instead, they are used to strip and polish industrial concrete floors. They allow removing epoxy and polyurethane paints, glues, mastics. They are also used to level all irregular surfaces.
For interior work, it is advisable to connect a vacuum cleaner to the sander to work without dust.
How To Erase The Marking On The Ground With The Milling Technique?
This erasing technique is the most widespread today in many countries. Floor milling machines use a rotary drum fitted with wheels or cutters. They make it possible to erase road markings in paint, in thermoplastic resin and cold coatings. They are also used for grooving floors and levelling uneven surfaces.
