I just built a timber staircase from newly sawn pine. The timbers are 4 X 12 so they will take a long while to dry. Some spots of blue mould have occurred on the rough lumber but I have stopped it with water and powdered chlorine for pools. It is all sanded and I want to know what I can put on the wood that will prevent the mould from starting again but also allow the moisture to escape. I assume polyurethane or varnish will trap the moisture, what about an stain, shellac etc...
