I hope this is not a sacrilege but I want to paint my log home –on the inside. Well, I’m looking at a log home w/flat horizontal boards on the interior walls. It has nice windows at the ends of a great room but the whole wood interior just needs lightening and I need more light . So I would like to know if interior walls like these can be painted and/or bleached-white washed. The finish on these walls is a flat, matte -not acrylic or anything shiny. If this can’t be done, I can never buy
