Hello TXXT123

Bitumastic Emulsion is *fantastic* stuff, for metal and planed/sawn wood. Two coats will give good protection and provide a DPC.

However, the only downside is that it also seals moisture /in/, so you may find that water is entering your wood from above, entering the wood itself and then soaking everything below the line of emulsion.

If you think of wood as a sponge (which it is), try to allow a path of egress. Either at the bottom (a post buried, for example) or not to go up one side (batten)
