I am contemplating finishing an outdoor porch floor with vinyl click & lock planks. Is this feasible?
The porch is 100% covered, and is on the North side. It receives no direct sunlight, except at late sunset, and no precipitation except the occasional rain splatter. Winters are generally -5C / 23F. It slopes 1in/4ft outward.
The subfloor is 5/8 PT plywood. It is open underneath that, and might in the future be closed with breathing aluminum soffits. Area is 400sqft.
Is this feasible? Any special considerations? Any better ideas?
Sealed vinyl decking (e.g. Ducan) is not preferred as I am looking for a DIY solution.
Tiling is an option, but I am concerned about longevity outdoors (thaw/freeze cycle).
Your suggestions, cautions and other input are much appreciated!
