Can I paint existing wallpaper with wallpaper prep-coat and then hang second coat of wallpaper?
It is really not a good idea to put wallpaper on wallpaper even with this great product. I know it is a pain to strip wallpaper and prep the walls but the result is worth it and will last years.This product is the best wall prep for wallpaper. Good luck with your project!
Thank you Marion
would it work to prepare a mirror wall for wallpaper?
I don't think so. The paper might adhere to the mirror for a time.... this may be a question for the manufacturer.I do love this product though.... I live in an old home with plaster and will only use this product to prepare the plaster walls for wallpaper.Good Luck!
Great question! I would be concerned about it's adhesion to glass, the manufacturer says it's OK for use on any surface. If there is any way you could rough up or etch the glass surface beforehand it may give the prep-coat more "tooth" - making less likely to peel off.
This is simply the best wallpaper primer on the market. I couldn't hang paper professionally without it. [...]
