There's nothing wrong with using an exterior finish indoors. The outdoor topcoats are formulated to add UV inhibitors and are more flexible (or should be) to allow for greater movement without crazing.

Take a look at General Finishes Outdoor Oil and their Exterior 450 stains.

 

I would be careful about the smell of the outdoor finish in a enclosed space. Esp if you have to occupy the space the same day of week. There got to be better choices look at Rubio mono coat. I bet they have something friendly.
You don't want to give yourself Drain Bamage.

Good Luck

 

test it with scraps :<))

Not after it's cured. I have a test board with General Finishes Outdoor Oil on it that has no odor whatsoever. If you're talking about during application, you need to take the same precautions as you would for any indoor varnish.

 

Good point Rich.
I guess If the wood was pre finished outside. But we never know what the passing crown will do without guide.
I've been painting in my house the last few days while running the AC. So far I haven't experienced any drain bamage.

Good Luck

 

Thanks, everyone. I'll plan to finish all the wood outdoors & let it cure before I attach it to the wall inside.

 

You probably want to use a water based deck sealer. It has fewer VOCs and should dry thoroughly in a couple of days. They come in a variety of colors from "natural" to a rainbow of shades. Also some are called Cedar and may have just the coloring you want.
