Q: If you wallpaper over Sempatherm wallpaper is it possible to strip and redecorate the wall in later years without removing the Sempatherm layer?

Posted On: 02/05/2013 By: Ralph Rayner

A: Hi Ralph. Yes you can redecorate even if you have wallpapered. Sempatap Thermal has a fibreglass surface and will not be affected by using a steam stripper or hot soapy water. Should you accidentally damage it with a wallpaper scraper, you can make good with polyfiller or plasterer’s mate.
Q: How do you cut this material?

Posted On: 25/01/2013 By: Mike

A: The best way to cut Sempatap Thermal Paper is using wallpaper shears or large scissors
