I want to use old barn wood as a floorcovering. I would like to leave it rustic looking but would like to put somekind of sealent on it for protection agains spills and scratches. I would also like to ensure that I am not bringing termites and other critters in my house. Does anyone know products or steps I should perform to fumigate / kill off anything in the barn wood without destroying / affecting it's look? Also, what should I use as a protective coating? Thanks for any help you can give!!
