Damp Proofing

Damp plywood wall smells

Anonymous user 28/02/2024 - 2.59 PM

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
