Wall was freshly plastered but was not a great job and was rather uneven, although this could not be seen under normal lighting conditions. The wall was painted and it was only when 2 wall lights were installed that it became apparent the wall was not smooth at all.
My first attempt to correct this was to use filler, then sand it smooth and repaint. Unfortunately the paint being used reacts differently when painted over existing paint than it does over mist coated filler and this made the problem even worse.
The second attempt was to sand the wall until it looked fairly flat which resulted in a surface that was partly bare plaster, partly mist coat and partly finished coat. This didn't work very well either, although better than the first attempt. I was able to remove some element thought repeated light sanding and repainting but not everything could be removed.
My third attempt was to sand back to bare plaster in the affected area, this is taking ages as the paint in Mylands marble emulsion, which contains ground marble! This dulls the sand paper within about 30 seconds so took about 3 hours to sand less than a 1m area.
The result has worked, but has just moved the problem, I now have a line around the area where along the transition from paint to bare plaster.
I've included 2 photos, 1 is under the light that I sanded back to bare plaster, then applied a mist coat of the mylands paint, the other is under the light that I filled, painted, then sanded lightly then painted again.
The first photo looks a little worse than it actually is, the seconds photo looks slightly better than it actually is.
Does anyone know how I can get rid of these lines in the paint? I feel like I'm going round in circles with this now.
Thanks
