Hi
I had some walls painted about 9 months ago.
I've had to do some cut-outs for AC which have now been patched and plastered. No I want to paint using same paint and colour.
Here are my questions:
Should I sand the rest of the wall before painting? (or is it ok bc it was recently painted?)
Can I just sport paint the effect areas for undercoat and first coat, and then do just one coat over the whole wall?
Any advice would be appreciated.
