Wallpaper businesses supply wall coverings for homes and commercial premises. Their ranges may include paper-based, vinyl, non-woven and washable wallpapers, as well as textured finishes, borders and large-format wall murals. Customers may be able to choose from different colours, patterns and surface effects, and request samples to check a design against the room's lighting and furnishings. Some businesses also stock wallpaper paste, lining paper, brushes, rollers, scrapers and other materials used in preparation and hanging. Depending on the business, services may include advice on selecting suitable coverings, estimating how many rolls are needed, and ordering products from manufacturers. Some wallpaper specialists or associated decorators offer wall preparation and installation, including removing old coverings, repairing minor surface defects, lining walls and hanging wallpaper.
