I'll confess that this is actually a ceiling question, not a wall question, but I hope the principles are the same. (Didn't seem to be anywhere suitable for this question other than here!)
We have a bedroom in our 2 year old extension. So far as I know, it's a standard plasterboard construction, but there is a flat roof above it.
In the window we have placed a roller blind.
A couple of times the blind has fallen down because the rawl plug fixing has come out. I've bodged a repair by using a larger screw and larger rawl plug but eventually the repair fails and the screw and plug comes out again. I've reached the limit of this now because I can't use a larger screw on the blind fitting.
So I guess it's time to repair the ceiling. The plaster is pretty dry and powdery up there. What's the best thing for me to do to repair the ceiling so that I can start again with fixing the blind to the ceiling at the same point?
Can I just put No Nails into the hole and then fine plaster over this to make a smooth finish which will hold another screw?
What fixing should I use next time I put the blind up?
