Hi, does anyone know if I can remove the white trim belonging to the Skånska Byggvaror conservatory? The wood is as damp as tinder, i.e., rotten behind the trim (measured 54% moisture yesterday and just over 20% today from the side). Other visible wood between 9-15% moisture, i.e., oil and paint = ok. I want to remove as much as possible and place a new block behind (oiled and painted). I'm considering putting sealant under the remaining wood, good/bad?
