Can I have some help please? I have removed some picture rails because there was so much dirt behind them and they weren't sitting flush to the wall either. The walls are rendered and the rails were held on with nails attached to timber pieces which fit into holes in the wall. I presume the timber pieces were put in first and then the nails were hammered in through the rails. In any case, I'm now left with holes in the wall and loose picture rails. Wondering whether I should: fill the holes with plaster and paint over - forget the picture rails put plaster in the holes and somehow stand there holding the rails on while the plaster dries try to use a nail gun through the rendered wall somehow try to glue the rails with wood glue - and stand there holding them while they dry. Help please. What would you do?
