Media blasting, popularly known as abrasive blasting or sandblasting, is a process where different types of media such as sand or glass beads are used to smoothen out or polish a rough surface. It is often done for restoration projects to remove a previous finish or rust on an item, or to prepare a surface for a new coat of paint.
Media blasting uses a lot of pressure to push out grits and impurities, which causes the blast to occur. Euroblast.co.nz notes the kind of medium to be used on a project depends on the difficulty of the removal and how much pressure the material can hold off.
Baking soda is not just a staple in everyone’s kitchen but the media blasting world as well. Using baking soda as a cleaning agent dates back to the 1980s when it was used to clean the Statue of Liberty in New York. This household item works great as a deodorizer and cleaner, which makes it the perfect fit for works like fire restoration. Since it is much less abrasive than other media, baking soda is a great material to use on delicate or ornamental surfaces.
Sand and grit
Sand or grit media are commonly used in removing impurities such as build-up, paint, and corrosion from surfaces. Since sand particles are of the same size and their edges are sharp, this type of media is effective in abrasive blasting. Sand and grit media are capable of cleaning the surface while leaving it natural and maintenance-free.
This blast material is often used on stainless steel, brass or bronze surfaces. It is less abrasive than the traditional sand and grit media since the particles used for this kind of blasting have a bead shape and round-edged. For a matte and satin finish, then glad bead sandblasting is the best choice.
Water and vapour
If a cleaning or surface preparation project calls for something with little to no dust, then vapour or wet sandblasting is the answer. As its name suggests, vapour and water blasting uses water stream, such as water induction nozzle in addition to a dry blast material. Since water vapour is emitted in place of dust, this type typically produces low dust. Also, due to the use of water, blast materials are significantly lesser compared to other types.
With the various types of media blasting, whatever the project, problem or situation is, there is always the right media to achieve the desired results.
