Concrete is a fairly easy surface to maintain. Some people choose to dye, stain, paint, or seal it, while others just occasionally clean it and go for a more natural appearance. There are many ways to clean concrete. Water cleaning or pressure washing are two commonly used methods. Sometimes, for the more resistant stains, chemical treatments are needed. In some situations, a technique referred to as abrasive blasting is used.
What is abrasive blasting?
Abrasive blasting is a technique that uses a very forceful spray of water or sometimes sand to blast away an unwanted surface on the concrete. This method can add texture to a slippery surface, or clean away deep-seeded stains.
How does it work?
Abrasive blasting requires a force such as compressed air or condensed gas. There are a number of products that can be used for the blasting. Sand, aluminum oxide, coal slag, bead blasting, and organic materials such as nut shells are all used.
Is it safe?
Precaution should be used when applying this technique. Not only can the particles hit you and cause injury, but some of the materials, such as small particles, can be harmful to your health. Be sure to wear protective clothing, and to only use the machinery according to the manufacturer’s directions.
Abrasive blasting is also used for decorative purposes. It can be used to create art patterns, or simply to add texture to an otherwise drab surface. If you would like to incorporate this useful technique into the care of your concrete, then request free estimates from skilled concrete contractors in your area.
