Media blasting is an aggressive form of abrasive cleaning where sodium bicarbonate (caustic soda) is blasted against a hard surface with compressed air. It has a milder, less toxic effect than standard sandblasting. An early use was on the preservation of the Statue of Liberty during the 1980s. Go to homepage

To use media blasting, it is best to have a clean work area with clean flooring. Prior to the operation, all surfaces must be spotless and any surface roughness removed. The work area should also be ventilated and allow drying before media blasting begins. There may be times when you have to add extra water to make up for water vapor lost during the blasting process, so it would be best to check with the manufacturer for instructions on how to adjust the mixture to achieve the right results. If possible, start with a clean surface so that the dust buster or other additional additives do not throw off the media blasting effects.
After the surfaces have been cleaned and any preparation necessary, the equipment and machinery used should be calibrated and prepared according to the manufacturers' specifications. This includes ensuring that each piece of equipment and machinery is running according to manufacturer's instructions and is protected by appropriate covers and guards. The surface to be blasted must be completely smooth and clean. A trowel with soft, clean sponges is best, as is an electrically powered rotating brush. Make sure to wear the correct protective gear such as eye protection, long sleeves, sturdy rubber gloves, and proper respiratory equipment. Click here for more info.
Other media blasting equipment includes a wet chemical gun that is used to blast acrylic signs. This is a single stage machine that is very versatile; it can be run at low pressure can be adjusted according to desired results. These types of machines are often referred to as sign lite or wet abrasive blasting equipment because they are primarily used to blast acrylic signs. The equipment comes with accessories including gun kits, gun rest, hand tools, and paint brushes. These accessories make it easy to complete the job, but if you choose to do it yourself, there are many helpful articles and guides on the internet and in bookstores that will help you get started in no time at all.
The final media blasting equipment that will be used is the sandblaster or sander. This is the most important piece of equipment because it is what will remove the metal from the surface that is to be blasted. It is important to use the right size, power and grit on the sandblasters. A sander that is too large or too small will not work well, and a sandblaster with the wrong settings will not perform as effectively as you may want it to.
There are many benefits to using the media blasting equipment for mold remediation, pipeline repair, graffiti removal, fine metal finishing, and concrete finishing. It is also used to clean out mold and mildew infestations in both outdoor and indoor locations. There are two types of media blasting that you can use to accomplish these tasks. The first type is dry-ice blasting which leaves a fine powder residue behind on the surface areas. The second type is the sandblasting process where the product will come out as powder and create a fine dust stream that is very effective in removing mold and mildew.
