Problems with pattern matching can be due to one of 2 things:
- Overstretching the paper when hanging. Pasting the wallpaper makes it more pliable and easier to handle. However, it also makes it more susceptible to stretching when ‘brushing out’ to remove air bubbles and flattening the paper to the wall. Extra care is required to ensure that the paper isn’t stretched lengthways as this will affect the pattern match. It is highly unlikely that the paper will contract in length when drying and any attempt to manoeuvre the pattern back will result in creasing.
- Manufacturing fault. The edges of all wallpapers are trimmed as part of the production process. If the rotary trimmers are not set to the right position and correct distance apart, then the position of the pattern on the edges of the paper will be affected.
