How should I remove wood mildew?
Before leaving the factory, all VELUX roof windows and sky- lights are treated with a temporary water-based fungicide and bactericide. After installation they should be given further coats of a good quality paint or wood varnish at regular intervals. If, however, condensation has been a problem, some discoloration or mold growth may have occurred and although the strength of the timber is unaffected, the result can be unsightly.
Removing wood mildew
- The mold must be killed using a sterilizing agent. Scrape off any surface mold, then clean the area with a solution of 1 part household bleach diluted in 10 parts water.
- Rinse well with clean water. When thoroughly dry, rub down wood with medium sandpaper. Repeat steps 1 and 2 until mold is removed.
- Finally, coat with a proprietary clear wood preservative and then finish with paint or wood finish as desired.
