I've heard that these are no good because they tear the wallpaper off the wall, which isn't exactly ideal considering you've just wallapered your house - maybe hooks would be better instead

I'm sure there's a lot of information out there thanks to a quick Google.

I am stripping 80s era wallpaper from our whole house in preparation for painting. Most of the house house been fine - the gib underneath has been in good condition. However in the 70s extension we have uncovered extensive areas of mould which is resistant to normal cleaning (warm soapy water). The gib itself is dry and we have cut a whole in the wall to check that the timbers and insulation appear to be dry as well. Does this gib need to be replaced or would a professional painter/decorator be able to clean it prior to skimming?

We have just brought a 1970s home which has painted wallpaper. We stripped the wallpaper in one of the small rooms (about 10m2 of wall). We were hoping to re-plaster and paint the walls ourselves as a plasterer would cost approx. $1,900+GST (including paint). The wallpaper came off easily enough but there are definitely some little imperfections in the old plasterboard which need fixing. Also, the joins between the plasterboard have been plastered but not taped beforehand. We were told that if we want to get a good finish, we would need to cut the groove out, re-tape and plaster over. It may be easier to just replace the gib, scotia and skirtings? Any advice would be greatly appreciated!
