What is grit blasting?
Grit blasting is a popular industrial method for smoothing rough surfaces or roughing up smooth surfaces by using pressurized abrasive streams. Both methods are done with the intention of further finishing a wood, metal or ceramic surface. There are many tools used to accomplish this feat, including portable and stationary machines. Depending on the surface type and the grit being used, the pressure streams come in a variety of strengths. The results can perform a job that would take hours of manual sanding into a few minutes. This process has been utilized by metalworkers and woodworkers since the middle of the 19th century.
