one is a tool that perforates the wall paper to allow water to get through. the other is a steamer that greately accelerates the absorption of water to loosen the wall paper.
Another trick is to have a lot of water and wet towels because you need as much time to clean out the glue as to scrape off the paper. You don't want to do it again when the scrapped off paper gets glued back to the floor it falls onto.
有缝，Painter说patch后直接paint。
记得咱们这里一直主张全去掉再Paint.是吗？为什么？
Once I had an old house had 4 layers old wall paper...
Cost me a crew of 4 a couple of weeks to peel them off and patch the wall...
If you are lucky with the non water absorbing newer wall paper you can get by without the trouble.
