Repairs & Conservation

Deterioration

Wallpaper deteriorates for many different reasons. These include the type and quality of the original materials and how the wallpaper was hung, problems with the building itself or through physical damage by people and poor methods of repair: Most wallpapers produced after c.1840, and particularly cheaper papers, are likely to have been made from poor quality, unpurified wood pulp, and may discolour and become brittle after just a few years. Dampness in walls and the environment of a building often causes staining, and can also lead to the failure of adhesives and weakening of the paper through mould growth. Damage can also be caused by over-exposure to light, which results in the fading of colours. The use of inappropriate adhesives for repair can cause irreversible discolouration and staining, and they will often fail after only a short period of time.

DIY repairs and professional conservation advice

DIY repairs may often be successfully carried out with or without the help of professional decorators, using traditional starch pastes. However, it is surprisingly easy to tear or stain old, weak wallpapers. If a wallpaper is historically significant, it is advisable to contact an accredited paper conservator, who should be able to offer general advice plus provide options for treatment and make suggestions for long term care.
