Started stripping some wallpaper prior to redecoration and discovered what looks like tin foil on the walls:
Wide shot:
It's a 1930's house. I don't think the "tin foil" extends beyond the chimney breast. Judging by the oldest layer of paper (that grey one on either side of the chimney breast), I'd say the "foil" has been there some considerable time.
Anyone any idea what it is / why it was put there? And what the black stuff underneath it is? The black stuff feels waxy although it doesn't rub off on your fingers so I don't know whether the waxiness is residual paste from the "foil".
Thanks for any info.
