Was just going to say, I used a steamer once and had to hold it on for so long ot blew the plaster in a few places. Oher than that once, I have always stripped majority of top layer. brush/sponge two strip widths with warm water and gently scraped off the paper. To keep a steady workflow, after stripping the first row I then wet the next row or two, so they are ready to move onto straight away. Once the furniture is away from the wall, I can usually strip a standard room, (12' x 12' say), in about 2-3 hours
