I have installed MDF skirting in a new build. There was some mold in one bedroom which has now gone away, it was black spores on the surface, quite possibly from the buyers furniture previously in store. The buyer (not the most easygoing purchaser I have ever had) has now identified spots on the skirting on the stairs. These are under the paint and look like the discolouring you get from knotting. Anyone seen something similar?
