I'll admit I'm not very good at decorating, but I have managed fill in the odd wall hole, sand down and paint with satisfactory results.
However, I'm having trouble fixing up a water-damaged ceiling. We had a leaking drain above which damaged about one square metre of plasterboard - some of it cracks along a join, a few spots which went brittle leaving some holes to fill and some other general paint flaking. Nothing too major, I thought.
So I sanded it all down and filled in where necessary, but I'm now having trouble getting a smooth finish before painting. It's damn hard work sanding upside-down by hand and after ages, once I get it down to a level, the cracks and filled-in bits start breaking up ever so slightly. So I'm either left with still-bumpy filler proud of the surface, or where I sand further the cracks seem to want to come out again, or new paint flakes begin around the where the previous edge was.
So is there a trick to doing it neatly, or will damaged ceiling plasterboard just never look right?
