Deciding between a lighter or darker accent wall depends on the effect you’re going for. Choosing an accent wall in a lighter color will make a room feel brighter and more spacious and complement rooms with less natural light. A darker accent wall will add drama and depth to a room and help make larger rooms feel more cozy and intimate.

To determine how many rolls of peel-and-stick wallpaper you need, measure the square footage of the walls you’re covering and divide that by the square footage that each roll covers. Add 10% to 20% of your total square footage to account for pattern matching or damage while installing.

Painting over wallpaper is an efficient way to cover it if it’s in decent shape. Before painting over wallpaper, make sure the surface is clean and smooth. You may have to remove minor problem areas, such as lifted seams or small peels, with a sheetrock knife or putty knife. Add a latex- or oil-based primer to keep moisture at bay before painting. You’ll likely need two coats of paint to cover the area.

Peel-and-stick wallpaper is designed to be removed without damaging walls, making it a good choice for renters or temporary design changes. However, damage to paint or drywall can occur under certain conditions. To prevent issues, the wall surface must be properly prepared before application—it should be clean, smooth, dry, and correctly primed or painted. Applying wallpaper to a freshly painted surface can cause the paint to peel off during removal. Additionally, removing the wallpaper too quickly or aggressively can also cause damage. For best results, always follow the manufacturer's instructions for both application and removal.
