And you had to treat it (chemically) in some way yourself to prevent the wood from becoming a breeding ground for fungi in the future, could you "spray"-laminate the wood with a highly concentrated solution of salt and water?
Not only would this "dehydrate"/artificially season the wood, it would also - once the water evaporates - leave a miscroscopic layer of salt in every nook and cranny in the wood, so any fungi attempting to grow on it would become dehydrated and simply die. Is this a good idea? I'm a college student, barely an adult and have absolutely no experience in home building, let alone any other DIY project, except for assembling furniture from IKEA.
Would this work? I don't want to have to mess around with industrial, toxic chemicals in the future for my own home where my future kids are going to have to live. Besides, when you spray with toxic chemicals the toxins just evaporate in the atmosphere and come down again with rain, hurting the environment and the fungal and bacterial balance in agricultural soil, thus inhibiting the conversion of organic matter into fertilizer/nitrates and nitrites etc. You know the rest, hopefully.
