Water blasting or hydrocleaning
Water blasting aka hydrocleaning is yet another variant of sandblasting, except that it uses water instead of sand. Water blasting is known to be quite effective for cleaning surfaces (walls, ground, vehicles etc.). Water blasting is based on a simple concept; water is sprayed at great speeds through choke (nozzle). High pressure water stream has so much generated force it removes dirt, contaminants, impurities and even soft layers from hard surfaces at very high pressures. Water blasting machine is similar to sand blasting machine with small differences; it contains a water pump, container, a hose and a nozzle which controls the stream of water.
Water blasting, much like sand blasting machine, is used mainly for cleaning and can be used for removing of paint on wall (graffiti), dirt on metal (mud on car), on asphalt (gums), tire rubber from airfield, concrete et cetera. Water blasting is also widely used for cleaning of equipment, especially in construction. Water blasting effectiveness depends on water pressure; at low low pressure (around 5000 psi), the stream is safer to use on sensitive surfaces (wood, etc.), however at higher pressures (10000, 15000 and higher) it is much more effective, at ultra high pressure it can even cut through concrete. Water blasting use in household is well known – whenever you are using water hose to clean stuff, you are water blasting.
