Yes, you can skim coat over wallpaper, but it is generally recommended as a last resort. If the paper is tightly adhered, sealed properly, and the right compound is used, it can save you hours of grueling scraping. However, applying wet plaster over paper risks reactivating the old glue, leading to bubbling, peeling, and failure.
Yes, you can skim coat over wallpaper without removing it, but it is considered a last resort when the paper is impossible to strip. The moisture in standard joint compound can reactivate the old wallpaper glue, causing the paper to bubble, peel, or eventually collapse under the weight of the mud.
"No, you cannot plaster over wall paper. The plaster will not adhere to wall paper, the moisture from the plasterer will dampen the wall paper and cause it to peel. The plaster will eventually crack and come away from the wall."
If you're planning to have your walls plastered, one of the first questions that comes up is: “Do I need to remove the wallpaper first?” The short answer? Yes, absolutely. Here's why skipping this step can ruin the job, and what you need to do before the plasterer arrives.
To skim coat a wall after removing wallpaper, clean off all residual glue, and prime the bare drywall with a high-quality, water-based sealer. Once dry, apply a thin layer of watered-down joint compound using a 12-to-14-inch taping knife, let it cure, sand it smooth, and apply a second coat.
Skimming Walls after Removing Wallpaper
Instead, a skim coat, made of a thinned joint compound, can be applied to the entire wall to make it smooth. The cost to apply a skim coat should range from $0.75 to $1.50 per square foot, including labor and materials.
Removing Wallpaper: 6 Disastrous Mistakes to Avoid
Yes, wallpaper is not only in style, but it is considered a fundamental design element rather than a basic accent. Modern, easily removable, and highly tactile options allow you to choose from three major directions:
Covering wallpaper without taking it down is highly achievable. The easiest and most permanent approach is painting directly over it, provided it is properly primed. For a completely smooth surface or a damage-free rental option, skim coating, applying new removable wallpaper, or installing wall paneling are excellent alternatives.
The simple answer is no you shouldn't. The reason behind this is plaster is only as strong as the bond to the wall. So if the plaster is stuck to the wallpaper then all that's holding it on to the wall is wallpaper adhesive.
While peel-and-stick wallpaper is renter-friendly and easy to install, it struggles on textured or humid walls, requires meticulous measuring, and can be frustrating to reposition. Over time, edges may lift, and cheaper brands can bubble or shrink.
Can You Plaster Over Wallpaper?
For most beginners, a medium-sized firm steel trowel is a good all-round skimming trowel choice. It is large enough to cover ground, but not so big that it feels unwieldy.
It's worthwhile to smooth out imperfections with filler and/or apply lining paper. Additionally, certain thick wallpapers can mask cracks, dents, and other problem areas, making them almost invisible. The best options are heavy non-woven wallpapers with textures, embossing, or relief.
Wallpaper does not impact a home's appraised value, as appraisers evaluate structural condition. However, it can significantly reduce your offers from buyers. Prospective buyers frequently factor in the high cost and hassle of removing it, which can cause them to lower their offers or pass on the home entirely.
Current wallpaper trends emphasize warmth, personality, and tactile luxury. The hottest looks include Trompe L'oeil (faux-textures like plaster or linen), Heritage Revival (vintage, cottagecore motifs), and Micro-prints (tiny, delicate patterns that add detail without clutter).
Wallpaper generally lasts between 10 to 15 years, often outlasting standard paint. However, the exact lifespan largely depends on the material, installation quality, and room environment.
Professionals remove wallpaper by using a proven, two-step process: peeling the top decorative vinyl layer, and then soaking and scraping the remaining paper backing and glue. They rely on basic hand tools and hot water or steam rather than expensive, harsh chemicals.
If you use stripes as a wallpaper and install it vertically it will make the room feel taller. The same is true when they're installed horizontally - it'll make a room feel wider. Larger rooms can benefit from a thicker stripe on the walls without it feeling too busy.
The top 2026 wallpaper trends feature a blend of tactile neutrals (like faux linen and concrete), heritage revival block prints, and immersive scenic murals. These styles transform walls into foundational art rather than just background accents.

Skim coating is generally more affordable than the cost of drywall repair or full replacement. The size of your room has the biggest impact on the cost of skim coating. It costs $1.10 to $1.30 per square foot to skim coat drywall. This cost doesn't include the price of drywall or drywall installation.
