Shot blasting employs the propulsion or blasting of small steel shots or balls of uniform size on a surface at high velocity. This technique removes any surface contaminants, pollutants and other coatings from surfaces like concrete and steel. The surface, free from all surface contaminants and blemishes, provides an ideal mechanical profile for bonding with other coatings and treatments.
Shot blasting is preferred in many instances as it provides a chemical free and dry surface after the treatment. In contrast to sandblasting, this technique of abrasive blasting does not generate large quantities of dust that is harmful for operators if accidentally ingested or inhaled. Dust from sandblasting is harmful to health if proper protection and safeguards are not employed during the operation.
The method is fast and offers minimum disruption to other activities. Concrete being a porous surface is prone to retention of chemicals, oils and other contaminants that penetrate through the surface. This technique is excellent for cleaning long stretches of concrete for motor ways, airport tarmacs, steel decks of ships and shipyards and other surfaces.
Many manufacturers of coatings specify that surfaces should be prepped by shot blasting technique to provide an ideal surface for bonding or application of paint. The method works equally well on concrete and on steel. The method is eco-friendly and does not use harsh chemicals. The surface is dry and ready for immediate use or further treatment. Equipment used in the process has efficient disposal methods to dispose of dust and other debris and contaminants.
Shot blasting can also be achieved with non-metallic materials like silicon carbide or aluminium oxide. Aluminium oxide provides a high quality finish with minimal damage or impact to the environment. Abrasives like aluminium oxide, plastic, steel shot and grit etc. are not harmful per se, but they can prove to be hazardous to the operator’s safety if projectiles are allowed to reach unprotected skin. Eye lesions and skin burns can occur if the shots accidentally reach the unprotected surface of the skin or eye.
Using this technique floor covering can be stripped of a number of coatings and coverings. Special equipment can also achieve cost-effective tile lifting using infrared or radiant heat to prepare the tile for mechanical removal. This method is ideal for the removal of asbestos and vinyl asbestos tiling. When you need a floor surface stripped and prepped at short notice, the most cost-effective and least disruptive method is shot blasting. Westminster residents and business owners can contact local contractors for using this method for their projects.
