Using a soda blast gun is a great for many restoration projects around your home or business. A soda blast gun uses baking soda (sodium bicarbonate) as its means of cleaning. What you are left with is a paint-free, rust-free and smooth surface. You can soda blast wood, metal, glass, plastic and even concrete. It is a very versatile machine and material. It is also environmentally safe. If you are the victim of graffiti, you are not left with many choices. You can paint over the graffiti, but that takes time and money. Invest in a soda blast machine, and you can remove the graffiti without damaging the surfacing, and you will have it on hand for other projects. The article below will show you how to soda blast graffiti from your wall.

Step 1 – Preparation

If there are windows or wood in the wall that you do not want to hit with sodium bicarbonate, you need to cover them with plastic. Do this for any areas that you do not wish to refinish with sodium bicarbonate. If you need to protect something behind the wall, then create a cover for it out of plastic propped up by metal poles. This will protect the area from the blasting.

Step 2 – Working with the Soda Blast Equipment

The equipment used to soda blast is not difficult to use, and is made up of 3 parts. Each piece of the equipment is equally important. The canister holds the sodium bicarbonate, the air compressor propels it and the gun itself shoots out and regulates its flow. Turn off all of the valves. You will find them on the gun as well as the air compressor. This is how you maintain the pressure. Connect a hose to the valve on the gun to the valve on the canister, and attach another hose from the air compressor to the canister. Fill the canister to the line with the soda, and then close the lid. To make it airtight, pull the ring which removes excess air, causing an airtight seal to occur. Without the seal, the gun will not work properly, as there will not be enough pressure.

Step 3 – Remove the Graffiti

Graffiti is paint, but you do not always want to remove the paint under the graffiti. Set the PSI to 30. This PSI is perfect for removing the graffiti without damaging the wall or paint behind it. Turn the air compressor on. Open the valve on the nozzle of the gun. When you are ready, pull the trigger. This propels the sodium bicarbonate. Aim it at the graffiti. Adjust your spot as needed, to reach all of it. Inspect the area from time to time, and continue as needed. Turn off the soda blast equipment, and then wipe the masonry down with soapy water.
