Hey all, so I kinda dabble with a bit of multifinish plastering with generally okay results. I used to work with a plasterer so understand all the basics of prep etc...
I plastered a wall at home around 6 months ago and have only just got around to painting. A couple weeks after painting I have had a couple of pretty big areas blow and crack that had no signs before hand.
Firstly I wanted to know what has caused this so I never repeat it. I'm slightly paranoid now that the rest is just going to blow but I have no idea why. I used 2 coats of pva and started to spread when the 2nd coat was tacky.
I would also like some advice on how to fix it. The majority of the wall is sound as I've gone around tapping religiously, but as I knock off the blown areas It always sounds hollow on the very edge of where it's been knocked off. NIGHTMARE! I've thought about knocking it all off and starting again but I would have to redo another wall too as it's joined with corner bead.
Would it be worth cutting around the blown areas with some type of knife or something to not disturb the rest?
If anyone can advise me with some info I would be mega grateful.
