Sandblasting - in house or portable
Sandblasting is a general term used to describe the act of propelling very fine bits of material at high-velocity to clean or etch a surface.
A sandblasting setup usually consists of three different parts: the abrasive itself, an air compressor, and a blaster nozzle. For etching and small object cleaning, a workstation to hold the piece of glass is also needed, as is some sort of collector to gather up excess dust. Sandblasting is primarily used for two somewhat different applications. The first of these is to clean a surface of anything that may be clinging to it. The second is to either etch or carve designs or words into glass or a similar material.
The first sandblasting process was patented in the US in 1870. As a cleaning method, it is often used for priming a surface for the application of paint or a sealant. When painting, one doesn't want to trap dust, dirt, or bubbles in a previous layer of paint, or other imperfections under the new layer. By launching small bits of abrasive at the surface at a high speed, all imperfections are knocked loose and can then be easily washed off, creating an incredibly smooth surface upon which to lay the new layer of paint. Sandblasting may also be used for such projects as cleaning the hulls of ships or large structures such as the Golden Gate Bridge.
What Classic Does:
- Structural/fabricated steel products to put a profile on them or remove rust and paint
- Steel framework to get ready for other types of finishing
- Wood to bring up the grain or remove the paint
- Concrete to expose the aggregate beneath the surface for architectural beauty
- Brick to bring back the original color and beauty
- Grafitti removal
- Stainless steel to remove the "blue" from welding
