Knotty pine ceiling

We have put knotty pine like this in every room we have remodeled so far. We are going to be starting the bathroom and want to put it on the ceiling in there too. Does anybody know what would be a good sealant to keep the wood from rotting from the moisture? Would the polyurethane be enough?

This is a picture of how we usually do the ceiling.

 

Not sure Ward.
I did the ceiling when I remodeled the back room with end matched T&G pine.

 

Nice looking ceiling that's what I used in the man cave I think the polyurethane should be fine ,it's not like water is being poured directly on it .

 

poly should be fine for moisture in the bath.

 

Poly should be good. Maybe both sides. I'd use spar varnish knowing my wife's long showers and the resulting fog bank.

 

A few pic's of man cave /ceiling.

 

Nice looking wide pine planks on the wall Will. Rough sawn from a mill?

 

Got them from a local guy who had a saw miser portable saw mill and he had a kiln , I really love the look of natural wood.

 

I love it! We get all our pine from my Husbands Grandpas land, then we take it to the saw mill to get planed, and tounge and groove. Kind of nice to have pine boards and logs from the old farm.

 

Cool you have something from the old homestead into the new one

 

Polyurethane is good. I'm putting knotty pine walls in a bath and playroom right now. I'm putting the first coat on before I install, and then lightly sanding after it's up and the one more coat.

 

If you are concerned about moisture, connect the room to some good ventilation. An exhaust fan is always a good idea when the shower is running.

 

It won't rot if its in your house. You should have no moisture in there unless your roof leaks. You can poly it or stain or oil or natural, what ever you like.

Pine will not rot unless exposed to the ground or moisture, and ground contact equals moisture so that is your enemy.

 

I see you said bathroom now.

Still that should not be enough moisture from steam to matter. It should dry out in an hour or less which won't allow it to rot.

 

Poly should be more than fine. I would make sure you have a good vapor barrier above it though.

 

Well, I might as well jump on this band wagon. Poly it. Should be fiiiiiiiine. What the hell? Make your tub right out of the pine. Then poly that too. Just watch out for the slivers.

 

They make boats out of wood, enough protectant and it will be water/rot proof.

 

Rot? Heck, my firewood has been sitting outside in the rain and IN humidity for 4 years now and hasn't rotted. The ceiling isn't going to rot...but if not adequately protected it will stain/weather/discolor. The ceiling in the pic looks pretty sharp...might as well keep it that way.

 

Thanks, that room was a pain in the arse! The logs were not fun at all to put up but it looks great so it was worth it. Not bad for a 100 year old farm house, can't wait until the whole thing is done.
