Deck is coated with mold, and stain is peeling
Q. My pressure-treated deck and outdoor stairwells are coated with mold. They are located in an eastern exposure facing open fields. They had been stained about eight years ago and are now peeling too. How should this problem be solved?
A. Were your deck and stairs coated with a solid color stain containing linseed oil? At this point, I suggest you have all the remaining stain removed. Try pressure-washing to make the job easier, but if this is not completely successful, you may have to use a paint-and-stain remover.
A paint store can advise you as to the best to use for these surfaces — probably a liquid remover, as they are less expensive than the gel or semi-solid types. Once the wood is clean, coat it with a product specially made for pressure-treated wood, such as the Wolman line that penetrates the wood and will not peel.by
