Services - Sandblasting

Edmonton's Premier Coating Specialists

Sandblasting is a generic term for the process of smoothing, shaping and cleaning a hard surface by forcing solid particles across that surface at high speeds; the effect is similar to that of using sandpaper, but provides a more even finish with no problems at corners or crannies. At Impact Coatings Inc. we use a Manus™ blast cabinet, which is essentially a closed loop system that allows the operator to blast the part and recycle the abrasive, and a Manus™ blast room, which is a larger version of a blast cabinet with the exception that the blast operator works inside the room. Both of our blast systems allow a majority of the media to be recovered through filtration systems to reclaim and reuse media making this a much more efficient progress than pot blasting in an open environment. At Impact Coatings Inc. we use only the finest grade brown aluminum oxide. As an angular, durable blasting abrasive, aluminum oxide can be recycled many times. It is the most widely used abrasive grain in sand blast finishing and surface preparation because of longevity and hardness. Harder than other commonly used blasting materials, aluminum oxide grit powder penetrates and cuts even the hardest metals and sintered carbide. Approximately 50% lighter than metallic media, aluminum oxide abrasive grain has twice as many particles per pound. The fast-cutting action minimizes damage to thin materials by eliminating surface stresses caused by heavier, slower cutting media. Aluminum oxide abrasive grain is the best choice for preparing a surface for coating both powder and ceramic. Virgin, brown aluminum oxide contains less than 1.5% free silica and is therefore safer to use than sand. The grit size is consistent and cuts much faster than sand, leaving a smoother surface.
