Whether it’s your residential or commercial property, repairs are always the most difficult because of the amount of money needed to complete one project. But repainting a car or your home or repairing the roof and other areas of your property should not require you to call a contractor and pay him thousands of dollars. There are ways you can do most of the work yourself.

One of the most important steps in sandblasting in Utah is preparing the areas to be repaired or repainted. The most common way to do that is by calling a sandblasting company. But the belief that sandblasting must be done only by professionals is starting to erode itself. In truth, you can rent a compressor, plug in a sandblaster, and remove the rust and stain from metal and steel.

Understandably, you are apprehensive about sandblasting the rust off metals and steel by yourself. But if you want to save some serious cash, this is a consideration that you need to make. To further prepare you for this DIY project, here are some tips that you can follow:

Learning the Ropes

Open that user’s manual and read up about how to operate a sandblaster. It isn’t exactly rocket science. It’s possible to learn how to properly attach and detach the nozzle in just a few minutes. You can be an expert in sandblasting within a day or a couple of days if you put your mind to it. But it is important to remember to wear protective clothing and accessories when handling sandblasters.

Minimizing the Mess

The biggest drawback about sandblasting is the mess that it creates. There is no simple way to minimize the mess that sandblasting creates when you operate it. However, you can protect the things that surround the area of the workplace. Since sand particles are tiny, they can get inside crevices and small cracks. The best way to prevent this from happening is to cover and tape off as many areas as you can using cardboard or a tarpaulin.

Avoiding Clogged Drain Lines

Sandblasting needs compressed air for it to become successful in removing rust from metal and steel. The high rate of speed that the sandblaster uses increases the moisture content of the compressed air. Couple with the humidity in the environment, it can cause the sand inside the tank to turn into a clay-like substance and clog the drain line. Before using the sandblaster, make sure that the line is cleared.

Angling the Spray Nozzle

Angling the spray nozzle directly at the rusted surface will remove the rust eventually, but the most effective way is to angle the nozzle to strike the rust from the sides. Remember that rust forms peaks and valley when it grows. Striking it from the side will wear it down quickly.

Avoiding Metal Warping

If you blast sand too strongly and directly on the metal repeatedly, you will have a different problem after the rust has been removed. You’ll find yourself with a piece of warped metal. The blast creates friction and thereby heat. When the metal heats up, it expands outward. While you won’t be able to see the warping of the metal while it is being blasted by sand, you’ll definitely notice it after the process has been done. Avoid sandblasting the same portion of the metal. If needed, allow the metal to cool down for a few seconds before blasting it again.

Remember that some cities may require permits before sandblasting. Check the regulations in your area before you operate a sandblaster. You must also warn your neighbors before sandblasting because sand particles might get in their driveways and garages.
