Sometimes, it is very difficult to scrape off wallpaper that has been painted with several layers of emulsion. This is because the surface of the paper has become so saturated with emulsion that water cannot soak into it.
The trick is to wet the paper and then lightly heat the surface with a blowlamp. The steam created will work its way beneath the paper, softening the paste so that the paper can be scraped off much more easily.
Stripping obstinate wallpaper
Water often fails to loosen firmly stuck patches of wallpaper. Lightly brush a thin mix of wallpaper paste on to the patch, and. When the patch has almost dried, wet the surface by brushing it with hot water. The layer of paste will help hold the hot water, letting it soak the paper. Alternatively. Score the surface of the paper with a sharp trimming knife or old hacksaw blade before soaking it with hot water.
Trimming excess wallpaper
When cutting off excess wallpaper round ceiling roses, corners of window frames or light switches. Leave the paper to dry for at least a day. Then make the necessary cuts with a trimming knife. Not only is it easier to make cleaner cuts on dry paper, but there is also less risk of the paper being torn.
Sealing wallpaper joins with a seam roller
The pressure necessary to seal down wallpaper joins with a roller can make them shiny. To prevent this, hold a strip of paper between the roller and the join. Do not use newspaper – the print may come off. Never use a roller to seal a paper with a raised pattern, such as Anaglypta; use a brush instead.
