we have a hole in the wall where an old light fitting used to be. We also have a new light fitting, the base of which is smaller than the hole in the wall.
How do we fill the hole so that the filler is strong enough to support the weight of the new light? It is not very heavy, but the hole is about 10 diameter. (It is a Victorian house, the plaster has horsehair in it and is backed by thin wooden strips..)
Please help... we were hoping to fit this light today!!!
