Applied four coats of home-made interior limewash paint. First two coats looked good, the third coat dried with a little dark blotching towards the bottom. Four days later I applied a fourth coat which has dried with extensive blotching on some walls but not others. I have used the same mix and application process throughout, aside from adding slightly more pigment in coats 3 and 4 (see below).
Unsure whether the fourth coat will improve given time (it has only been three days) - however these blotches don't look like a normal drying out irregularity, they look as if they're around to stay! I'm unsure whether the problem has been caused through an application issue or something being drawn through from beneath (in which case why has it only appeared at coat 4?). All coats had 1-4 days in between applications and were brushed on thinly to a pre-dampened wall.
I added a little more pigment to coats 3 and 4 as the colour was extremely pale for coats 1 and 2 - could this be a contributing factor?
Most of the surface beneath is original Victorian lime-plaster which we filled and sanded. There could be traces of adhesive there as it was papered previously.
The ceiling looks flawless even though I used the same mix and application technique - so it seems unlikely that the mix and application alone is to blame.
Any thoughts welcome on what this is and how to rectify - thanks,
