Tips for Successful Wallpaper Installation

• Purchase all rolls from the same batch (check the lot numbers) to ensure color consistency
• For patterned wallpaper, buy an extra roll for complex rooms or future repairs
• Prepare your walls properly - clean, prime, and repair any imperfections
• Consider the wallpaper type (pre-pasted, non-pasted, peel-and-stick) when planning your project
• Allow for acclimation by bringing the wallpaper into the room 24 hours before installation
