It is popular as well for its knack to create decorative looks to metal, wood, concrete and, of course, glass surfaces. Making marks and etches can make a material like glass look more appealing to the eyes, thus the procedure is deemed notable to many manufacturing and design firms. If you have seen glass panels with intricate patterns and etchings, it is most probably done with through blasting. Creating great carvings on wood is another thing that the sandblasting equipment can be used for. Wood furniture, signage and other ornaments can be produced faster and with more flawless results because of blasting. Decorative walls can also achieve varying textures if rendered with the abrasives.

Its supplies include a blasting tank where the abrasives are stored, an air compressor that allows the abrasive materials to be sprayed at intense pressure, a nozzle which is the tip of the equipment from where these abrasives shoot out, and the abrasives itself. Before starting with any blasting activity, these supplies must be checked first if in proper working condition. Observing the wearing of proper protective gear is advisable as well. When inhaled, the abrasives may cause difficulty in breathing and even more serious respiratory issues. Failure to wear protective clothing may also result to grazes in the skin. Thus, a helmet, a pair or working gloves, an apron and a set of safety shoes must be worn at all times when performing sandblasting.
