What is sandblasting?&#8221; open=&#8221;true&#8221;]<strong>Sandblasting<\/strong> is a cleaning process by which rust, paint and scale can be removed from any surface without damaging it.<br \/>\nThe process involves eroding the most superficial part of a material by abrasion through a jet of sand and air.<\/p>\n<p>Different types of abrasives are used, at different grain sizes, depending on the material to be treated.<\/p>\n<p><strong>Our products<\/strong> are suitable for two types of sandblasting:<\/p>\n<ul>\n<li><strong>dry sandblasting:<\/strong> a high-speed jet of air and abrasive material is directed against the surface to be treated;<\/li>\n<li><strong>sandblasting with a humidifier:<\/strong> allows the dust produced by dry sandblasting to be broken down using water.<\/li>\n<\/ul>\n<p>[\/vc_toggle][vc_toggle title=&#8221;2. When is dry sandblasting recommended?&#8221;]<strong>Dry sandblasting<\/strong> is an industrial, mechanical and construction process that is recommended in order to clean and prepare materials for subsequent treatment (painting etc.) or to make engravings on stone, marble, ceramic, glass or wood artifacts.[\/vc_toggle][vc_toggle title=&#8221;3. When is sandblasting with a humidifier recommended?&#8221;]<strong>Sandblasting with a humidifier<\/strong> is a method that allows the abatement of process dusts.
