Sandblasting is a terrific way to remove old paint and metal coatings so you can prepare it for painting, powder coating, or other purposes. When you know how to sandblast, you can make quick work of it and save yourself some elbow grease, and maybe even avoid a minor injury from an angle grinder.
Before you start your DIY sandblasting project, you need to rent or buy the right equipment and set it up properly. The following three steps will help you to do that.
Step 1: Choose Your Gear and Set It Up
Whether you are renting or buying a sandblaster, you need to choose the right equipment for the job and set it up correctly. You have the choice of a pressure or a suction sandblaster, and most people opt for the pressure sandblaster.
A pressure sandblaster is better for getting rid of paint and other substances to prepare metal for paint or powder coating. A suction blaster works best for finely detailed sandblasting.
You will need an air compressor capable of delivering constant pressure and a hose and nozzle that enables you to control the sandblasting. You will need a nozzle that will allow sufficient flow to efficiently remove paint and other substances.
Step 2: Prepare to Sandblast Your Project
You need to connect the air compressor to the blast pot and feed the hose and nozzle inside the sandblasting booth before you can start sandblasting. You should wear safety gear, including eye protection, gloves, and a heavy apron – preferably one made from leather.
You might have someone helping you by feeding the hose to the blasting booth so you do not have to worry about tripping over it. While you are blasting, you can adjust the pressure as needed to get the best results.
Step 3: Use the Best Angles to Get Ideal Results
Once you have your sandblasting equipment set up and ready for use, you need to use the best angles to remove material from the metal surfaces. Most likely, you will sandblast metal surfaces that are round, angled, or flat and require many angle changes to get the best results.
You want to use the best angles that enable the material to strike at right angles to the surface and remove all the paint or other coatings on the metal surfaces. Once you have all the metal stripped and prepped, then you can chrome it, paint it, or powder coat it to your preferences.
