Last year (with a lot of help from this forum) built a shiplap cladded workshop, and used Tung oil on it. This year I gave the boards a light sand and applied a couple more coats..
Given that last winter the wood was fine, I'm surprised to find that already this year there is already a lot of mould/discolouration appearing...and I also am getting it on a second building that was constructed this summer, and which had 6 coats applied over several warm weeks!
Any ideas what has gone wrong?...and although I doubt that there is much that can be done before next spring, how could I rectify this?
