Topic tags/keywords: door door bottoms rot

My workshop aka garage has an entryway door, 32”x80”. It is 40 years old and has rot on the bottom. I am planning to replace it with a Lowes douglas fir door that has glass panes on the top half.

The problem with the original door is that it has rotted on the bottom. When I paint the new door, should I paint the bottom and top to seal it? Or should I paint only the bottom?

This is probably obvious, by sometimes my brain works too hard on these issues.

Thanks for the help!

Paul

Sounds like you’re not wanting to paint the door, but rather have it keep some type of natural finish?

The outside, where it’s getting the rain, should definitely be hit with a coat of primer. Consider oil-based if possible. Old school, perhaps, but the best approach in my experience. Hit the door with a ROS to give the primer lots to grab hold of, let it cure a couple days, then paint.

Inside, do whatever you’d like.

Another obvious consideration is the source of rot. Need gutter work above the door, outside? Maybe consider an awning, or roof extension / portico?

Good luck!

My outside doors on the outbuildings are fiberglass. I know…. it’s sacrilegious for a wood worker to have a fiberglass door, but out there, in winter, the bottom of the door might be covered with snow for weeks (depending on which door on which building) and with the thaw/freeze, they may be wet for a long time or even encased in ice! So…. because I have stuff I’d rather be doing than fussing with a door, I put the fiberglass ones in and they don’t rot. :)

To answer your question directly. Seal the top and the bottom. You need to seal the end grain so that it doesn’t wick water up into it.

Charlie: We don’t get much snow in south Louisiana. Deep snow has not happened since the 1950-60s.

Earlextech: I can paint the top and bottom with exterior latex. Is there something else, like an oil based primer that would work better for the top/bottom?

Thanks again.

No the latex is fine. I would thin the first coat so it absorbs into the door better.
