Building Cleaning Exterior Artios Painting a approved contractor with this areas exclusive territory rights to the Caltex System is an opportunity to maintain the attractiveness of buildings through regularly scheduled cleanings.
Most buildings have exteriors consisting of brick, vinyl siding, aluminum siding, stone, masonry, or cedar. Up to now, high pressure washing with bleaching agents and acid cleaning were the only method to clean these surfaces. Besides being harmful to the environment, these products actually damage the surface. Vinyl becomes chalky with bleach. High pressure acid cleaning damages the brick by pitting it, and it can burn the brick, turning it to an orange color.
The Caltex LVLP environmentally safe system does solve all these problems and makes exterior surfaces look like new. In one step, we can clean and restore all the above surfaces by removing the unsightly mold, mildew, dirt, chalkiness, pollution, and environmental staining. Over the past 2 decades, we have developed great expertise on large and small scale restoration projects. Caltex International Ltd. invented, improved, and implemented the LVLP technology 17 years ago. With millions of jobs having been done since then, this Low Volume Low Pressure technology uses organic, non-toxic, biodegradable, USDA approved, and environmentally safe products manufactured by Caltex.
Mike Baker of Artios Painting suggests washing a house by hand, and prespraying with Calbrite [a mold inhibitor]. Then using a power washer to rinse. Pointing the wand down will keep the water from going under the siding, if some water does gets under the siding it should dry out quickly, that's why they hang it loose. My power washer puts out 4 1/2 to 5 gallons a minuet, with 1000 to 4000 psi, a garden hose can put out up to 8 gallons a minuet,and up to 600 psi which is enough to soak under the siding which makes the under side more soaked, also you spend more time in one spot cleaning which soaks the under siding more. Power washing only, with out scrubbing is like washing a car it looks good when its wet but when its dry you can see stripes and misses with chalk remaining, and uneven cleaning. To remove rust use a half lemon and salt, scrub the rust and rinse.
