I need to replace a couple front porch posts/columns that are rotting, so I'm just going to replace all of them.
Original posts are just 4x4's with some wood casing and trim around it. I'm going to do roughly the same thing with maybe a little different trim.
I plan on painting them all white.
1) For the casing and trim, is it ok just to use standard pine 1x4's and 1x6's you'd find at home depot if I just sealed and painted them well?
2) What do you recommend I use for water sealing, caulking, and painting the columns?
