Thermal wallpaper peeling help please....

[Bdulko]

Hi all. After many attempts at combating mould and mildew in my sons room I have bought some thermal wallpaper to go on the cold wall.

I slathered on the paste onto the wall. It was the paste they recommended to buy with the thermawall paper. It said to use a bucket of 5kg of paste per roll. I used about 6/8th of a bucket for the roll as the wall was so thick of paste.

After 48 hours I then applied wallpaper over the thermal wallpaper and left it for about 4 days.

On the 6th day (from when I applied the thermal paper) the wall in the corner was feeling very wet so I went to peel back the wallpaper that was over the thermal paper and it lifted up the thermal paper. So I pulled at the thermal paper and my shock the entire thing came off easily.

I've attached a video of the thermal wall paper coming off


Obviously the room is cold, doesn't go below 15 degree as radiators then turn on but the walls are cold (hence why I needed the wallpaper)

Can always suggest what i may have done wrong? I'm having to rebuy it all but don't want to get wrong again!!!

I would say the room is too cold and too damp for the paste to dry out. (It is thicker than I expected, I have also attached a screenshot of the paper)

Have you considered applying polystyrene wall insulation first, then any wallpaper of your choice? Click me
