I have an old barn that I will be working on to fix up. Mostly just replacing rotted sections of boards and re-nailing boards where the original nails had rusted away to nothing. I can already tell that nearly every board has rot on the bottom 1-2 ft of wood but the parts above are still in good condition as far as rot and damage goes.
I was wondering what people would suggest for treating the new wood to protect from rot and of course treating the existing wood. I have no set plan as far as if I will paint it or just treating it and leaving the natural wood color and texture. Of course painting it or most wood sealers or treatments require period reapplying and about the only thing that is a “must” for the finish is that it be something that can last many years (10 or more would be ideal) with minimum fuss and work.
I did see some info on a treatment called LifeTime by Valhalla – http://www.valhalco.com/index.php – but not really sure if that protects from rot and insects or if it is mostly just a cosmetic thing. I know treatments like Thompson water seal have to be applied every few years also.
