HELP!
We moved into a 1970's house about six months ago and are in the process of redecorating the hall (downstairs at the moment).
While using a steam wallpaper stripper I found that the plaster was bubbling up; I was only hovering it over an area for about 5 - 10 seconds just enough for the paper to dampen.
The plaster skim coat is now "peeling" off in chunks, the base coat of plaster is intact but very dry and sandy. When brushed (lightly) with forefinger the sand dusts off.
The area effected is about 1.0m by 0.75m but other parts of the area also sound hollow when knocked, especially above lintels / door ways.
What is the best way to tackle this problem so this does not happen again e.g. long term solution? Is it best to strip back to thermal brick or just get a plaster to "patch" areas?
Is it safe (or wise) to continue stripping the painted lining paper with a steamer?
Have I bough a lemon....(?)
Thanks for your advice in advance.
James.
