A Contractor’s Guide To Sandblasting

sandblasting

Sandblasting is an advanced process for cleaning all kinds of sturdy surfaces. It involves tiny pieces of materials such as sand and walnut shells being blasted at a very high velocity to clean surfaces. Sandblasting is a full-fledged service offered by companies and it is done both commercially and residentially. Commercially, sandblasting is done in a variety of places such as machine shops, manufacturing facilities, metal structures, bridges, concrete tilt-ups, factories, and airports. Residentially sandblasting is done on steel surfaces, concrete, log cabins, and walls to name a few.

Types Of Blasting

There are different types of sandblasting, namely wet abrasive blasting, bead blasting, wheel blasting, hydro-blasting, micro-abrasive blasting and automated blasting, dry-ice blasting and bristle blasting. Each of these methods differs based on the mixture used to blast surfaces.

Wet abrasive blasting: This technique uses extremely fine or coarse particles with varying densities. It allows the use of hot water and soap to enable degreasing along with blasting.

Bead blasting: This technique involves using fine glass beads at extremely high pressure to clean the surface. Bead blasting does not cause damage to the surface.

Wheel blasting: This form of blasting uses a wheel to propel particles to the surface.

Hydro-blasting: This is also known as water blasting. It is primarily used to remove old paint, chemicals and build-up on surfaces. Hydro-blasting involves the use of highly pressurized stream of water.

Micro-abrasive blasting: The whole aim of using micro-abrasive blasting is to clean a small part on a larger surface. It is a process of dry abrasive blasting in which small nozzles are used to blast a surface.

Dry-ice blasting: With this type of blasting, air, and dry ice are used to clean surfaces. This is used on surfaces which can get damaged by sandblasting.

Process Of Sandblasting

There is nothing very complex about the process. It is a three-step process which involves, identifying the material of the surface which needs to be cleaned, preparing the area surrounding the region which needs to be cleaned and then the final procedure of sandblasting the surface with the help of appropriate equipment.
