Paint-preparation washing removes agreed loose dust, webs, surface dirt, chalking, and buildup before coating work. The cleaning plan must account for the existing substrate, coating condition, windows, fixtures, landscaping, access, drying time, and the painter's schedule.
Clean Surface uses controlled pressure, soft washing, compatible treatment, and rinsing according to the surface. Loose or failing paint may release during preparation, but washing is not a substitute for scraping, sanding, repairs, moisture testing, adhesion testing, priming, or manufacturer-required preparation.
The painter or coating contractor remains responsible for final substrate acceptance and determining when the surface is dry and ready. A written handoff prevents cleaning completion from being misrepresented as a coating warranty.
