It’s possible to hang your own wallpaper, but the process is tedious and potentially frustrating, and it can be challenging to get seams to line up and look clean and professional. Plus, depending on the type of wallpaper you’re installing, using too much or too little adhesive could cause damage to your drywall or plaster, peeling, and bubbling in the final product. It’s usually a better idea to hire a professional wallpaper installer to do the work for you, as the relatively low cost is justifiable, if only to avoid damage to your walls.

Textured or patterned vinyl wallpaper designs are the best option for hiding imperfections. Embossed designs or faux finishes like brick, wood, or linen textures are especially effective at camouflaging dents, cracks, or uneven surfaces. Avoid smooth, shiny finishes, as they can highlight flaws rather than conceal them. 

There can be too much of a good thing when it comes to accent walls, so avoid creating one in every room in your house. Some rooms, like bathrooms and kitchens, don’t naturally lend themselves to accent walls, so it’s best to skip them there. Of course, your home should reflect your own sense of style, so if accent walls in multiple rooms appeal to you, there’s no hard-and-fast rule forbidding it.

Hiring a professional wallpaper hanger is usually a worthwhile idea because, while the application of wallpaper itself is easy, getting the finished product to look good is complicated and takes a lot of practice and patience. A professional wallpaper hanger will not only be able to hang your wallpaper seamlessly, but they will also get an even application of wallpaper paste to avoid bubbling and imperfections immediately and over time. Plus, they can provide their professional opinion on whether to remove or wallpaper over an existing layer of wallpaper.
