Hi guys, i had a problem with a peeling wall which was an external wall in a back room of my house, the paint would just peel off the wall in quite large chunks, this problem was there when i first purchases the property
when i had some work done, a mate who was just learning plastering said he would plaster the walls for free for me...
the idea to me was great, i got new plastered walls and i didnt have to pay, especially with the other work i needed to do in the house..
he pva's the walls and provided a 2-coat skim of plaster over them for me..
unfortunately he also offered to paint the walls for me and didnt do a mist coat or diluted layer and just rollered straight onto the walls (giving 3 coats)
now on the external wall, i am getting peeling and bubbles, i presume i can just take it back to the bare plaster and re-paint the right way (correct??) but will i have a problem as it was skimmed straight over the previously bad wall aswell?? the wall was never knocked back, just pva'd
and also, on the internal walls now, if i wash them with a damp cloth (if say, someone marks them) the paint washes off with the cloth back to the plaster..
im looking for the cheapest but practical solution really, with the internal walls, can i just apply an undercoat layer now and then re-paint or will i need to go back to bare plaster
and with the external wall, do i need to scrape the whole wall back and then re-paint with a mist coat, and if so whats the best way to get the paint off the wall?
sorry for long post and thanks in advance for any help!!
i should add that the external wall is a very old lime plastered wall (but i understand lime plaster was pretty good for retaining damp?)
