3 Benefits of Dustless Sandblasting as a Pre-Painting Surface Preparation Technique

Sandblasting is one of the best techniques for removing old paint and rust when preparing a car for a new paint job. It is effective and leaves the surface smooth and ready for renovation. However, auto shops can choose from different sandblasting methods, with most service providers opting for the dustless technique. Dustless sandblasting eliminates the need for sophisticated safety gear since small amounts of dust produced. Nonetheless, dustless sandblasting has many other benefits as a surface preparation technique.

Limitless Applications

Modern cars are made from composite materials. For instance, the body could be manufactured using metal, whereas the bumper could be produced from plastic or fibreglass. Therefore, while a highly abrasive sandblasting medium will not damage a car's metallic surface, it might cause dents on the plastic bumper. It might lead to expensive replacement, which a car owner may not have planned for. If you are thinking about repainting your entire car, then ask for dustless sandblasting. The reason is that the procedure can be used safely on a myriad of surfaces, including metal, plastic and fibreglass. Moreover, you save time since dustless sandblasting eliminates the need for changing the abrasive medium when working on pliable surfaces. Therefore, regardless of the surface you are cleaning or the coating you are removing, you can rest assured that dustless sandblasting will achieve excellent results.

Cleans Surface Completely 

Normally, an auto painter needs to clean a car thoroughly after sandblasting. The reason is that other sandblasting techniques leave a thin film of dust on the surface, which must be cleaned before painting begins. If you skip the step and start spray painting, you are likely to end up with a rough painted surface. Moreover, you might need to apply a rust inhibitor after sandblasting with an abrasive medium and wait a couple of hours before painting. However, you do not have to worry about leftover dust or further surface preparation steps with dustless sandblasting. The technique does not leave dust behind since it cleans a surface automatically, making it ready for paintwork.

Protects the Surface Against Heat 

One characteristic of abrasive sandblasting methods is that the media used produces heat on hitting a car's body. Therefore, it is essential to take short breaks after sandblasting for a few minutes to prevent the surface from warping due to excess heat. Conversely, dustless sandblasting protects the body from heat since water cools the surface during the process. Furthermore, you can sandblast a car's surface continuously without the time-wasting breaks in between.
