Mildew is a living organism that thrives on the various components of paint. The fungi feed on the oil in alkyd paints, and on the protein thickeners in latex coatings. Paint used to contain mercury and lead, which are harmful to the environment, but were excellent at preventing mildew. Since they were legislated out of use, it has become more difficult to combat mildew, and although all top line paints and stains contain anti-mildew agents, it is impossible to guarantee mildew will not recur. Mildew control has therefore become a homeowner maintenance issue.
If mildew is painted over without being treated (killed), it will recur almost immediately, eating its way through a fresh paint job.
We will take every precaution possible to avoid this by washing any affected area thoroughly. This washing, done by hand, is with a solution of TSP, bleach, and water. The bleach kills the mildew, and the TSP or a more environmentally friendly alternative washes away the deteriorated paint the mildew had destroyed. Although the washed surface will not look terribly clean, the bleach will have done its job, and once completely dry, the finish coat is ready to be applied.
