Ffs don’t use a stripper , it forces steam into hairline cracks and blows the plaster . (If walls are plastered) score the paper with a sharp blade then soak with warm soapy water .Lots of . You use soapy water as it sticks , and doesn’t run down the wall so fast ! Careful round the sockets……
If it’s an old house, this is good advice.
For me re-doing an old victorian place, I want to avoid blowing old plaster off if possible. Scoring then soapy sponge, wait a sec then scrape gets 95% of it off. Then I break out the steamer for the 5% or so that won’t shift, as by that point I can tell if it’s on dodgy plaster or not. If the plaster’s a bit dodgy then I get out the elbow grease.
It’s also a far less sweaty job without a steamer going.
I quite like podcasts for DIY work, would be my other pro-tip 😉
