Abrasive Blasting Vs. Sandblasting: What’s the Difference?
Abrasive blasting refers to the process of surface treatment where a blasting medium that is propelled at high pressure is used to treat a surface. Treatment of a surface could be to apply a coating or to create a decorative pattern on the surface. However, the most common treatment is the removal of unwanted surface coatings.

However, this practice has become nearly extinct as technology has allowed people to come up with better mediums for surface treatment. However there are still some companies offering sandblasting in Houston.

For a long time, sand was the only medium used for blasting processes. This made the name sandblasting to be synonymous with all abrasive cleaning processes then. However, nowadays, sand is the least favorite medium used. This is because sand has unfavorable properties for the procedure.

It can cause damage to most surfaces and also to fine-tuned blasting equipment due to its impurities. The most unfavorable property of sand though is the inherent health risks it poses. Sand has a high silica percentage. Silica can lead to permanent respiratory damage if inhaled.
