Greasy mark along skirting board and picture rail

Anonymous user 03/03/2024 - 3.35 PM

Hello We had our house painted and it all looked lovely but we recently noticed that on one bedroom (outside) wall there was a sort of half inch dark line above the skirting board and below the picture rail. The rest of the room is fine. At first we thought this must be damp as it looked "wet" but are now wondering if this is a greasy mark caused by the caulk/filler. The decorator only used caulk on the parts of the room which have the problem. Is there anyway of covering up this mark or would we have to remove all the caulk and patch up the paintwork? Many thanks

Obviously the paint applied has not keyed to the surface ,you will have to sand down where the stains are and apply oil paint (old gloss or undercoat) to the areas Once dry ideally the following day re apply the wall finish to where it has been sealed with oil paint .you may have to apply a couple of coats to these areas and that will sort out your problem

Use a oil based undercoat on the effected area allow to dry and emulsion over with the required colour should be fine

I cannot be sure what caused this But the solution would be Treat the effected area with a stain block or a Zinseer primer allow to dry then touch in with the wall colour Hope this helps Tony Wells Decorating

As this is only on an outside wall I would say it is condensation causing the discolour. So what happens normally is that any slight moisture in the room is absorbed into the walls assuming they have a breathable paint on them. But where there is caulk the moisure won't be absorbed so sits on the surface for longer. So the solution is to either eliminate the moisture (not easy) or remove the caulk and use a different type of filler, then prime and paint it. If you think this is the case don't use any stain block paints, especially oil based because they will simply seal that area even more.

I would personally wash down the affected area and clean away the caulk and re do it again.Iff that failed I would use oil based paint on stain and let it dry overnight and then repaint with wal colour.
