What is sandblasting?

Sandblasting is used to clean and prepare surfaces such as wood or metal using an abrasive material. However, contrary to what the name suggests, sandblasting doesn’t always use sand.

So, what is sandblasting and where is it used for? Find the answers and more below.

Sandblasting Overview

Do you ever wonder how skilled renovators remove paint and corrosion off old buildings to make them look good as new? Sandblasting is your answer.

Sandblasting is a surface finishing process that uses a powered machine to spray abrasive particles under high pressure on a surface. 

It’s called sandblasting because the sandblasting machine uses sand to blast away paint, dirt, rust, or some other form of corrosion on a surface to make it smooth and clean.

However, you can also use steel grit, copper slag, powdered abrasives, coconut or walnut shell to do the job.

The process removes some of the top-layer material to create a smooth texture ready for painting, finishing, or whatever else you need.

How is sandblasting performed?

To perform sandblasting, it’s important to make sure you’re wearing the appropriate personal protective equipment. If not, the abrasive particles can irritate your eyes.

It can also cause silicosis if you inhale the material. Be sure to wear gloves, masks, and goggles to protect yourself among others. 

To start, sand or your chosen abrasive material is poured into the sandblasting machine. After, the conventional air compressor connected to the machine is activated. 

You can now begin to blast across the surface of your material. Pressure is usually  50 to 130 pounds per square inch (PSI).

Where can you use sandblasting?

Sandblasting can be used in a variety of settings. You can use it to strip off paint and corrosion from old cars, houses, machines, and other surfaces. 

Cleaning services also use this method to clean small tools or concrete surfaces like driveways, walls, or pavements. It’s also a great way to smooth and polish devices like a rusty gas range from an old kitchen.

You can use it to sharpen grind tools and create etched signs. It’s also one of the most effective ways to eliminate mold from your home. 

If you use bricks and stones for your house, sandblasting can help you restore the authentic image of your bricks. 

Aside from construction, sandblasting is also a great way to create impressive art. Modern sculptors often make use of this technique to carve patterns on the surface of wood, metal, glass, or stone.
