3 months ago I painted a south facing window-cill with Dulux Brilliant
white non-drip gloss. Now I notice that where there are items on the
window-cill the paint has discoloured underneath them...Has anyone got
any ideas as to why??



If it was plant pots on the window sill, then the acids and salts from the
soil will make loverly marks in the paint. If it was just ornaments and
things, then it more than likely been polish or cleaning fluids that have
stayed under them and not been wiped away. Or it could be that the
surrounding area is bleached by the sun more than the areas that were
covered by the items.
