What does everyone do to protect the interior walls? I really like the nice clean look of the birch walls but I think I may need to seal them? I am worried if I leave them without a sealant then cleaning them will be difficult or they may get stained. I have 2 dogs I am sure will brush up against the walls at some point.
What did everyone do? I used polyurethane on the exterior should I use this on the inside. Will it darken the wood or make is shiny? It seemed to do this on the exterior plywood.
