Over time, buildings, vehicles, concrete walls, parking lots and other surfaces will become dulled and tarnished by dust, grime, soot, mold, dirt, mud, graffiti and loosened paint. The way to remove this buildup and bring back the original appearance of your property begins with a thorough cleaning.
High pressure cleaning, also called hydrocleaning or waterblasting, is the use of water propelled at high speeds to clean surfaces and materials. By focusing and pressurizing the water stream, the force generated can be used to clean a multitude of surfaces dirtied by gum, pollution or graffiti. In its extreme high pressure form, water is used in many industrial cleaning applications requiring the removal of surface layers.
Surface preparation
Before any protective coating or sealant is applied to a hard surface such as asphalt, concrete or metal, the surface must first be prepared. High pressure water can be used to prepare various surfaces for repair and reapplication of coatings. Power washing can be used to remove elastomeric, urethane and hot-applied coatings from driveways, walls, streets, commercial vehicles and more.

Tools for power washing
A pressure washer is a high pressure mechanical sprayer that can be used to remove dirt and grime from building exteriors, loose paint from walls, sealants and membranes from concrete, gum from sidewalks, and even rubber residue from airport runways.

The basic pressure washer consists of an electric motor or gasoline engine that directly drives a water pump, a high-pressure hose and a trigger gun-style switch. Just like the nozzle of a garden hose, the pressure washer adds its own power to create high pressure and velocity to the water stream.
Several different types of nozzles are available, each useful for a particular application. Nozzles that deliver a higher flow rate lower the output pressure. Most nozzles attach directly to the trigger gun. Some pressure washers, in combination with a particular nozzle, allow detergent and other chemical cleansers to be introduced into the water stream, assisting in the cleaning process.
The volume of a pressure washer is expressed in gallons per minute, which is designed into the pump and not variable. Pump pressure is expressed in pounds per square inch or PSI. Pressures range from 250 to as high as 30,000 psi.
