Hi,
Really frustrated at the moment with bedroom painting - bubbles approx. 1-3mm in diameter appearing every time paint is applied.
Hopefully the following will explain :
I believe the wall to be fine as there were no bubble issues when first "finished"
The paint is a Craig & Brown 1829 Chalky Emulsion which I have used many times before with no problems
The reason I had to revisit the walls was due to some large cracks that I wasn't happy with so stripped them back to refill, sand, etc. with the hope of a better finish!
The problem I believe is when the roller was washed out in soapy water using liquid soap ( don’t ask) rather than washing up liquid, and the next coat applied has then contaminated the wall everywhere the roller has been since with some sort of grease/oil from the liquid soap.
In loads of places now, I have scraped back the bubbles, washed/stripped the wall back to previous colour (needed to use B&Q non-caustic paint & varnish remover), washed this off too, but bubbles still appearing. I have of course jettisoned the offending roller, but the bubbles still appear which is why my contamination theory seems most likely to me.
What is going to be the best (and least time consuming) way to fix this problem? Have seen various posts re: primer/sealer e.g. Zinsser but can this go on the surfaces as they are now, or is it more crappy scraping that's required first?
Really hacked off with this room (can you tell?), so confirmation of my theory (or others proposed) would be helpful, along with how I fix this for good!
Two photos included - easier to see on 2nd one as paint is cream!
Many thanks.
