While a compressor which produces between 18CFM to 35 CFM is better for larger jobs where a more powerful experience is needed. While an industrial type of sandblasting needs a CFM of 50 – 100.Can you reuse sandblasting media?
This means you can only use it one time. Either because of the low hardness of the media, the force with which it is being propelled, the hardness of the surface being blasted, or a combination of each – the blast media disintegrates into particulates that are too small to be reused.Can I use silica sand for sandblasting?
