Our Wallpaper Paste comes in powder form to mix with water. It contains a special mixture of methyl cellulose fibres of various lengths, and does not include resins (which would affect breathability!) or preservatives. Methyl cellulose alone is known to have nearly no effect on the breathability of the wall, making it suitable for older properties and lime.
It’s also important to consider the type of wallpaper you use, as this can have a greater bearing on breathability. If you would like more information you can contact us here.
