Can I use interior stain for inside and outside( under poach & eves)

December 8, 2018

I am installing hemlock t&g inside and outside of the home. I am getting the hemlock pre-finished. They are going to use an interior stain. Since I am use the hemlock out under the porch ceiling and eves, the refinisher does not think I need to seal the wood at all. Is it necessary to seal the wood?

Any advice would be helpful.

    I'd add a couple coats of a clear finish. It will look better and be easier to keep clean.

    Interior finishes don't have UV protection or fungicides added to the mix like many exterior finishes do. That being said, there are plenty of hemlock sided buildings around here with no finish at all. The wood eventually turns silver gray. It will last longer with a finish and with regular application of finish can be kept looking "newer".
