Getting ready to hang about 6800 sq ft. of 1×8 T&G pine. That’s just over 2 miles of the stuff…

Anyone have any tips on how to finsih this much material? Hand brushing polyurethane on all of it??

Any quick way to give a fast smoothing sand?

Plan to finish before hanging….certainly the ceiling.

Any comments from those who have done it before would be great.

Thanks!
