Stripping paint from a vehicle, boat, airplane or other large object can be a long and tiring process if you use methods such as sanding or chemical stripping. There is also the risk, using these methods, of severely damaging the bodywork underneath, which can adversely affect the new paint job.
This is why many industries, and even a few savvy DIY enthusiasts, opt for media blasting as their go-to method of paint stripping. It easily strips paint and rust, giving professional results with less manual labor and much greater safety.
Safe for Most Surfaces
Media blasting will strip paint without damaging the substrate – even if that substrate is plastic or wood. It also smooths out pitted surfaces on even the hardest metals, providing an excellent surface for painting or powder coating.
This method is widely recognized as one of the best to strip or remove contaminants like rust (oxide), corrosion, imperfections, old paint or powder coat from the surface of hard materials such as metal, fiberglass and carbon fiber.
It is also highly effective at creating an etch, or adhesion profile, to a metal surface. This surface profiling, or “roughness” makes for vastly improved adhesion for subsequent surface finishes such as powder coat or paint.
Media blasting used to be called sandblasting, but sand is no longer used because of the inherent health risks of inhaling particles of silica. Depending on the application, there are now many alternative media that can be used for fast, effective and chemical-free paint stripping.
Paint stripping using media blasting works a lot like pressure washing, only much more abrasive. It uses compressed air to shoot tiny pieces of material (media) out of a nozzle and onto the surface you want to strip. Commonly used media include:
* Plastic beads
* Crushed walnut shells
* Aluminum oxide and
* Glass beads
Leave It to the Pros
Unless you really know what you’re doing, paint stripping using blasting media is a job for a professional. It requires specialized equipment, makes a mess if not carried out in a specially enclosed environment, and can lead to sheet metal distortion if not executed correctly.
