Sandblasting Services

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.

This is the primary task of sandblasting. Paint and corrosion can be challenging to get rid of when relying on conventional cleaning techniques. A sandblaster can remove stubborn paint and rust from cars, parts, and machines without harming the metal underneath.

Sandblast cleaning is not confined to just large surfaces. It is a reliable method to clean small instruments and tools.

The sandblast process leaves a surface shiny and polished, making it a perfect solution to remove irregularities from metal or plastic mechanical parts. It removes burrs, tags, or excess material to ensure an easy assembly.

Inferior surface preparations can lead to poor coating applications. Without the removal of all contaminants, you are drastically reducing the life of the coat.

Note: Not all materials are appropriate for a sandblast preparation. Consult with our finishing experts to see if your project meets the requirements needed for a quality sandblast process.

Sandblasting is a surface finishing process that involves spraying abrasive particles under high pressure against a surface to smooth, roughen, or clean.

A surprisingly large number of particles are available for use during sandblasting. Using the wrong particle or process can cause surface damage. Spay-Tech technicians are properly trained and experienced with various blasting agents and processes. Hiring an inexperienced worker or taking on as a DIY project sets you up for safety risks, poor quality work and potential damage to your product.

Sandblasting is most often used in commercial applications. Although there are many uses around the home, sandblasting can be dangerous and can cause damage to your surfaces if not done properly. Varying PSI and blasting media are used depending on the need. Sandblasting is a relatively inexpensive service, therefore we recommend leaving it to the pros.
