Green damp on wall batons

[rhurbarb]

Im currently renovating my home and i have 2/1 inch baton screwed to the wall .I have noticed the batons have recently turned green ...Never used to but im concerned about it and wondered if this was a big problem or am i being dramatic about it and should just put the plasterboard to it.I am putting celotex between the batons inside the house ...Thank you ..Rhurbarb

How long have they been there?

You should put a DPC behind them though.

They have been off and on a couple of times .I have had the wood in the home kicking around for about a year and a half.... ..When i ripped the home apart there was no damp so i havnt put anything behind the batons ..Are you saying i need damp prove sheeting ? .And just like to point out i havnt had inner walls up or plaster for 2 years so maybe the cause of the wood going green possibly as some of the wood i havnt even used gone the same colour its pretty nippy in the home Thanks Rhurbarb..

Without knowing exactly what is there etc. if I was doing it I would use treated timber and run a DPC up behind. Cheap DPC (not hyload), is about 3 quid for 20 meters so pretty cheap and will help protect as the years roll on. Also I've always found it easier to use 3 inch timber so you can stagger the fixings, helps keep it rigid. Hope that helps a bit ....
