Sandblasting to Remove Paint
One situation that a commercial property manager or owner is bound to encounter is a parking lot with flaking paint due to constant striping over the years. Parking stalls, handicap stencils, fire lane, etc…all that paint will eventually stack up and make it impossible for new paint to stick to the surface below the current layer.
The answer to this problem in almost all circumstances is to sandblast, a process that’s been around since 1870, the present traffic markings to start over fresh with a clean surface.
Sandblasting, also commonly referred to as abrasive blasting, is a process of forcibly propelling a stream of abrasive material against a surface or object under high pressure to remove, in our case, the contaminants or striping paint currently on the surface. Our method when sandblasting parking lots or garages requires a compressor and a pot which is where the compressed air and sand are mixed. The mixture then travels through a hand-held nozzle where the sand is then directed towards the surface or work area.
The Process of Sandblasting
Likely the first thought of people when the process of spraying sand around with compressed air is, “What a mess that must make!”
Those people aren’t wrong. Depending on the work area the media used in the blasting process will likely be widespread in the vicinity. However, C&D also specializes in the removal and clean up of the sandblasting process and so property managers and owners have nothing to worry about.
Overall, sandblasting isn’t super quick and due to the porous nature of concrete the removal of all striping paint is not guaranteed, but blasting when it’s all said and done efficiently cleans better and faster than other traditional surface cleaning techniques. Due to this, sandblasting is not an inexpensive procedure. There is the cost of everything involved including the sand pot, air compressor, sand or other media, labor, etc.
Due to this, it may be best for some properties with large parking lots or garages to sandblast small areas each year to maintain appearance and overall quality of the property.
One thing is certain though — you will have to remove traffic markings at some point and it’s much more welcoming to tenants and customers and less expensive to get it done sooner rather than allowing the paint to stack up causing an eyesore and driving away possible business.
