MAINTENANCE
The exterior factory-applied finish requires maintenance. Following the procedures described below will ensure optimum performance and appearance over the life of the finish.Superficial surface dirt can be removed by washing with a garden hose equipped with a soft bristle, long-handled brush. Heavier accumulations of air-borne dirt, dust smoke, and salt spray can be removed with a mild solution of household detergent s such as Handy Andy, Mr. Clean, Ajax with Ammonia, etc. Other cleaning solutions consisting of alcohol/water mixtures (Windex) are also effective. Grease or oily materials may require the use of stringer cleaning compounds such as Fantastic.
With any cleaning operation on a vertical painted surface, streaking will be minimized if the surface is washed from the bottom to the top. Always rinse the cleaned surface with clean water to remove excesses of detergent solutions or cleaner that may remain. Prolonged contact with the paint film can cause damage.
Wet paint, tar, caulking compound may be removed with kerosene or mineral spirits. Stronger solvents or abrasive type cleaners should be avoided.
Cracks resulting from joint movement should be caulked with a high-quality caulking material such as Dow-734 silicone.
Mildew is a fungus that is most common in geographical areas near water such as the East, West, and Gulf coast, Great lakes area, rivers and valleys and other areas of high humidity. Mildew thrives on warmth and moisture and will grow best under these conditions. It is so adaptable, however, that it can flourish to some degree under all climatic conditions.
Mildew growth is usually brown or black in color and, for this reason, may be mistaken for dirt. The presence of mildew can be conformed by placing a drop of household bleach on the suspected mildew area. Of small gas bubbles develop in the droplet of bleach and the area bleaches out, mildew does exist.
Mildew will grow on any organic surface, including plastics and paint films. Routine maintenance should include periodic inspection for and the removal of surface mildew.
Small damaged areas in the film (nicks and scratches) may be touched up with a matching Pittsburgh Paints 78-line Sun-Proof semi-gloss acrylic latex paint (Pittsburgh Paints dealers have color formulas for all standard Flexacron colors).
Larger damaged areas may require the use of a primer. Where this is indicated, use a high-quality alkyd (oil based) exterior wood primer such as Pittsburgh Paints 1-70 Universal Primer, or Pittsburgh Paints 6-9 Exterior Wood Primer.
