What is an easy way to take off old wallpaper?
Answer:
1) Lightly scratch the surface (do not dig into the underlying plaster)
2) using a wet sponge wet the scratched surface of the wall several times
3) leave the water to soak in.
4) scrape the wet wallpaper off.
If you have a steamer you can use the steamer after stage 2 this makes the scraping easier and quicker.
