Damp Proofing Question
Damp plywood wall smells
Previous owner used plywood for a wall section (1100x2800) the ply got wet from leak in loft (leak now fixed). Wall is 18mm ply two pieces with gap in middle of about 10mm. One side where bulk of leak came down had been painted and the wallpapered. I have removed wall paper and painted over with about 5-6 coats of emulsion, however it smells funny (our lass says like urine smell). I have taken out light switch and you can see it had clearly soaked quite a lot of the water up and looks a bit rotten. The smell is clearly coming through the paint still. As I have finished bedroom and sealed all edges and made good and due to me removing all loft water now (gone combi) ie so definitely no chance of more water. Is there a seal I could put on to prevent smell and will mould in wood not spread any further as there is no damp? Basically I don't want to have to rip them out. Thanks in advance any help
If the timber has soaked in a lot of water then this moisture can feed the fungi wet rot
Causing the smell this will carry on until the moisture has gone and probably rotted the board, I would if possible find a least a way to spray behind with a timber fungicide or rip out and renew.
