Building exteriors are the most common surfaces where business and homeowners consider a thorough pressure wash as regular maintenance or preparation for painting or resurfacing areas. Many other surfaces that need pressure wash maintenance are parking lots, decks, boats, concrete surfaces, vehicles, trailers, equipment, mobile trailers, to name a few.
Hydrocleaning, high pressure cleaning or waterblasting are terms used for a high pressure mechanical sprayer that can be used to remove loose paint, gum from sidewalks, mold, grime, dust, mud, and dirt.
Here at Omni Cleaning in San Diego, our hydrocleaning, in combination with special chemicals, aids in the removal of graffiti. This process (especially when the water is hot) is used as a quick rinser of the softened graffiti. Sometimes people use a pressurized mixture of air/sand or water/sand to blast off the surface of the vandalized area, thus etching the surface and therefore making it extremely difficult for anyone to ever use high-pressure cleaning as a follow-up process.
Sandblasting, when used in graffiti removals, often overcleans a surface and is capable of leaving a permanent scar on the building surface, so it is wise to use Hydrocleaning.
Any time a rigid surface, such as asphalt, concrete or metal, needs to have a coating applied, the surface must first be prepared. Hydrocleaning has been used to prepare for the application of such coatings.
Coatings are used to protect concrete from rain and salt, and to create a smoother surface for human use. Concrete can also be covered with carpet or tiles using a heavy duty glue or mastic. Asphalt and concrete can be painted to communicate acceptable travel patterns, potential hazards, or for aesthetics.
Call us if Hydrocleaning can be used to remove such materials off and give your building the fresh clean look.
