Hi. We are stripping wallpaper and have discovered what we think is PVA under the wallpaper. It is white and peelable, but not peeling half as much as we'd like! Is there anything we can use apart from soapy water and scrapers to hasten its removal. It must be lung-friendly as my husband is asthmatic. Any help is much appreciated, otherwise it's going to be a very tedious weekend! Thank you.
