Sand Blasting

SANDBLASTING BY TRAINED PROFESSIONALS
Also known as “abrasive blasting,” sandblasting is the process of smoothing (or roughening) and cleaning a hard surface by forcibly propelling a stream of solid particles across that surface under high pressure and speed.

The term “sand” in sandblasting is a general term used to reference any tiny bit of material. Spray-Tech Finishing stays away from real sand because it contains silica – a material found naturally that can cause debilitating lung disease after it breaks down into dust and enters the lungs. Aluminum oxide is our preferred blasting agent but we utilize various other blasting materials as well.

Media selection is critical when considering that different media types come with varying qualities like density, particle size, hardness, etc. Sandblasting machines have a chamber on top where the blasting media is poured. It is then connected to a dedicated air compressor that propels sand out through a handheld nozzle when activated. Depending on the need, the pressure of the sand may be anywhere from 50 to 130 PSI.

The sand is then “blasted” with force to clean and smooth the surface of an object.
