How to Use a Sandblaster

A sandblaster is a piece of equipment used to make rough surfaces smooth. It works as a machine version of sandpaper. The machine uses artificial sand which is blasted against the surface of an object. This process can also be used to shape and clean a surface.

To begin using a sandblaster, close all the valves. The process differs with each model and brand of sandblaster. Refer to the instruction manual that comes with the machine you purchased.

Fill the sandblaster with sand until the top seam. Check the manual to see if there is a preferred type of sand. Be careful not to spill sand on the other parts of the sandblaster.

Wear your protective gear. Mask, gloves, and goggles are the common types of protective gears used while sandblasting. These gears are commercially available at hardware stores.

Pull up the ring closure to seal off the tank. Turn up the sandblaster’s main valve while holding up the ring. Locate the nozzle end valve and open it fully.

Slowly and slightly open the sand mixing valve. Look at the sand coming out of the blaster. If it gives off a fine sand vapor, you can proceed to the next step. If the sand spits, surges, or clogs, slowly close the valve. Clean out the sand from the blaster and repeat the above steps.

When the blaster gives off a fine mist of vapor, you can proceed to sandblasting. Keep the sandblaster at a 45 degree angle while working on the surface. If you see that water clogs in the valve, remove the tip. Open the valve then close it.
