I’m about to install a short length (7 ft) of “classic” shape white oak hand rail against the exterior wall of my Northern CA house. The deck and final steps to the rear door (where the rail will go) is redwood….sealed to the usual redwood look.
I’d like to stain the rail to a color close to the redwood, but have been advised that I should first coat the bare oak with sealer. My original plan had been to mix up a stain combo to reasonably match the sealed redwood, then brush on at least four coats of Minwax satin finish polyurethane.
Given the exterior use, and the numerous coats of poly, is the sealer really necessary, or even useful ?
Thanks for tips and opinions
