“Many homeowners wallpaper over wet mainly for cosmetic reasons,” agrees Nischal Pomu. “Damp staining, hairline cracking and uneven surfaces can make a room look tired very quickly, so wallpaper is sometimes seen as a quick way to improve the look without major repair work.”
However, wallpapering over damp is usually a temporary solution while the problem is being investigated. “The problem is that wallpaper rarely solves dampness; it usually only hides the symptoms for a period of time,” notes Nischl.
“There are situations where wallpapering can still work once the wall has stabilized and dried,” he continues. “For example, an old chimney breast may leave historical staining after the original problem has already been repaired. In those cases, after proper stain blocking and preparation, wallpaper can sometimes be used successfully.”
Wallpapering can also be a cheaper option compared to removing any plaster, tackling the problem and re-plastering the wall/ceiling. Yours to keep temperature of the house Correct levels can also go a long way in helping prevent dampness from returning once the main problem has been dealt with.

The best wallpaper for wet walls
If you have walls that suffer from damp, or are currently suffering from it, you definitely don’t want to use standard wallpaper when papering over damp. Alisdair Simpson, Managing Director Retford Wallcoverings Limited Explains why.
“Standard pulp-based wallpapers are generally unsuitable for damp-affected walls, as constant exposure to moisture breaks down the material, often leading to staining, mold growth and adhesion failure.”
If you are going to wallpaper over wet areas, you will need to use a specific type of wallpaper to solve the problem. “Specialist systems such as Wallrock Dampstop Thermic are designed to help prevent the appearance of penetrating damp and associated staining,” explains Alisdair, “while using paste-the-wall lining paper on top to create a durable surface suitable for further decoration.
“When using Wallrock Dampstop Thermic, it is especially important that dimensionally stable PTW wallcoverings are used, as conventional wallpapers can be more susceptible to movement and adhesion problems on non-porous metal surfaces.”
However, once the Wallrock system is applied, “standard wallpaper can be used if you’ve covered the area with damp-proof foil and/or thermal lining paper,” says Alasdair.
