Protecting behind wainscoting

johnstown

Hi,

I intend in install 12mm tongue and groove wall panelling onto an old stone wall freshly plastered with NHL lime mortar. The old cement plaster was a bit damp in places.

Behind this I will fix 2x1 timber batons onto the lime mortar plaster, with a breathable felt between.

The whole thing will be vented also.

I want to ensure the batons and back of the tongue and groove do not rot. Thus I am wondering what would be the best thing to treat the timber....

a) Wood preservative such as Protim
b) Multiple coats of paint (e.g primer, undercoat and finish coat)
c) Some kind of coating such as polyurethane
d) Something else..

Any advice would be much appreciated.

I am trying to address the underlying cause of the dampness, but cannot be 100% sure of success, hence why I want to have the wood protected.

Thanks

Once there is circulation in the room you should be alright providing the timber isn't getting wet. But if the dampness isn't fixed your not going to hide it.

Yes, hopefully I can sort the damp problem out. Its eminating from the outside.. French drains and work on cills etc is required...

thanks
