Wallpaper on one wall can add drama to any room with less effort and expense than covering the whole room. Its very much like painting one wall (accent wall). It also lets you choose a bold pattern that would be overpowering on four walls. Begin by taking photos of the room you want to change and measure its dimensions. Take these with you to the interior design or wall-covering store or anywhere wallpaper is sold. If possible, ask a specialist to help sort through options that’ll work well with your existing furnishings. The specialist will also help you pick the best wall for the new paper and estimate the amount to order. Some papers can be hard to hang, especially fabrics, rolls with uncut edges and other designer papers. Always check the hanging instructions and ask the dealer about the difficulty level. If you’re a novice paperhanger or fall in love with a super-expensive paper, consider hiring a pro.
Be sure to fill holes and smooth your wall before beginning. Rough spots might show through the paper. Then seal the wall surface with an acrylic primer. It dries hard and smooth. This allows you to slide the paper a bit more easily to tighten seams. And depending on the condition of the wall, give yourself a half of day to a full day to complete this project.
