Bought some 4 x 4 douglas fir beams not realizing they were interior grade, can they be sealed with something and last outside on a deck?
Floor is mostly new cedar stained with TWP 1501 cedartone last summer, love the color.
Was looking to stain the posts and railing a darker color, even solid color.
Any suggestions?
Probably should not be used outside. May have issues with decay or rot.
