How to Use a Sand Blaster
Introduction
One of the most effective ways to complete a do-it-yourself project around the house is with a sandblaster. Various projects that might require this machinery include stripping surface paint from bricks or concrete. Sandblasters are loud, obnoxious machines that can seem intimidating at first glance. All it takes is a little understanding into how it operates and you will be on your way.
Before using a sandblaster, understand what type of material is blasted. This can be any number of materials including dry ice, steel beads and ground corncobs. A select few also use sand. The machinery powers up from a water or electrical source to push the select material through an air compressor and onto the desired surface. This takes place through the attached nozzle or hose.
As with any machinery, there are a few safety tips to keep in mind. Before operating a sandblaster for the first time, familiarize yourself with the machine. Know where the on/off switch is in case of immediate need to shut the machine down. Make sure the handle grip is sturdy and in place. Use a sandblaster in well-ventilated areas. Equip yourself with safety goggles, or other eye protection and a dust mask. Keep in mind that using a sandblaster on older brick material could cause potential damage. Always maintain a reasonable distance between yourself and the intended surface area. Move the sandblaster nozzle in slow sweeping motions to prevent damage.

Instructions
Locate a local tool store or home improvement center that rents sandblasters. Inquire about all associated fees cleaning policy.
Determine the length of time that you will need to rent the sandblaster. Small jobs such as a patio or fireplace will require a one-day or less rental period. Larger jobs such as plastering a house will require anywhere from a few days to a week in length.
Determine the strength level in pressure per square inch increments. Higher-pressure measurements create smooth surfaces. Too high however can cause damage. There should be someone available at the rental center to assist with this.
Return home and read instructions carefully.
Dress in protective garments including safety goggles, dust mask and work gloves.
Fill the sandblaster with selected material to the fill line. Make sure all valves are closed.
Once filled, seal tank by pulling up on the ring closure.
With the ring closure in the “up” position, turn air valve on. If the ring closure is down, material will seep out from the tank.
Leave the nozzle valve closed. Open all other remaining valves.
Open the nozzle valve in a slow moving motion. A steady stream of material should begin to come out of the nozzle. It should be in mist form.
Aim the nozzle at the desired surface.
Move the nozzle back and forth in a sweeping motion.
When finished, turn the machine off.
Clean the machine as needed.
Return sandblaster to the rental location.
