Can System Three Epoxies be Used for Floor or Deck Coatings?

System Three epoxies provide exceptional protection to wood components, in both interior and appropriate exterior applications.  However, we do not recommend them for concrete/wood flooring or exterior wood decks.  This is mainly because of the difficulty and expense involved in getting an acceptable appearance.  Products made specifically for concrete/wood floors are economical and generally easy to apply and provide a good appearance as well. but  There are a number of brands available at retail paint and "big box" stores.

Exterior wood decks are best finished with a penetrating oil or stain.  Because they penetrate rather than forming a film on top of the wood, the expansion and contraction of the wood will not cause the coating to crack and peel.  But they will weather in a short period, so plan to recoat at least once a year.
