Pressure washing is the bare minimum of cleaning methods recommended for preparation of exterior surfaces. Exterior paint will chalk overtime when exposed to the sun, and this chalked film will break the bond of any future paint coatings applied over it. It is important to remove all the chalked film prior to coating, or you will have a very short life paint system, regardless of the quality or performance characteristics of the paint.


		Normal pressure washing in the 2,400 to 4,000 psi range (pounds per square inch) will remove all the chalked film, and can also remove light surface corrosion in preparation of applying a coating system.

Ultra-high-pressure washing can also be used to clean corroded areas and can sometimes be used as an alternative to grit blasting. The results depends to a very large extent on the condition of the surface. Compact corrosion scale cannot be completely removed at a reasonable rate until pressures exceed 2100 kg/cm2 (30,000 psi)

Induspray is a qualified high- pressure washing contractor able to tackle projects of any size.
