Step-by-Step Guide to Paint Over Wallpaper

Step 1: Prepare the Wallpapered Walls

Properly preparing the walls is the most important step before painting over wallpaper. If the walls are not properly prepped, the paint can peel off along with the wallpaper. Here is how to prepare the walls:

  • Lightly score the existing wallpaper using a scoring tool or very fine sandpaper. This roughs up the surface so the paint can adhere better. Avoid gouging too deeply.
  • Use a mixture of hot water and fabric softener or diffused vinegar water in a spray bottle to saturate the wallpaper. Let it soak in for 5 minutes. This allows the existing wallpaper glue to soften for easier removal.
  • Gently peel off any loosened wallpaper using a putty knife or paint scraper. For stubborn areas, reapply the liquid mixture and let soak before attempting to peel again.
  • Lightly sand the entire wall surface after removing wallpaper pieces. This roughens up the remaining wallpaper and glue residue.
  • Fill any holes, cracks, or uneven spots with lightweight spackle compound and let dry completely. Then sand smooth.
  • Wash walls with trisodium phosphate (TSP) cleaner and rinse to remove any remaining glue or soap residue. Let dry fully before painting.

Step 2: Pick the Right Paint Type

For the best paint adhesion and durability on wallpapered walls, use high-quality latex or acrylic interior paint. Avoid flat paints, as they do not adhere well to wallpaper. Here are the best paint finishes to use:

  • Eggshell or Satin Finish: Provides a subtle sheen that makes walls washable. The finish is not too shiny.
  • Semi-Gloss: This medium to high sheen option is very durable and scrubbable. It works well in high-traffic areas like hallways and family rooms.
  • Primer/Paint Combo: Consider using a combo product made specifically for painting over wallpaper. It serves as both primer and paint in one.

No matter what finish you select, always opt for paints with a binding primer already mixed in for best adhesion.

Step 3: Apply a Wallpaper Paint Primer

Priming the walls after you have removed the wallpaper pieces and properly prepared them is extremely important. A quality primer designed for wallpaper provides an extra bonding layer that helps the paint better adhere to the slick wallpaper surface.

Some all-in-one primer/paint products made for painting over wallpaper already include primer, so you can skip this step. If using regular wall paint, be sure to prime the walls first with one of these recommended primers:

  • Drywall Primer: Provides extra gripping power to surfaces like wallpaper.
  • Stain Blocking Primer: Stops stains from bleeding through new paint. Useful if your wallpapered walls contain smoke stains or water stains.
  • Oil-Based Primer: Adheres perfectly to glossy or slick surfaces like old wallpaper.

Apply primer evenly across all prepared wallpaper walls using a premium roller sleeve or nylon/polyester brush. Allow to dry fully before painting.

Step 4: Paint the Wallpapered Walls Properly

Once your primer has dried completely, you are ready to apply the paint color of your choice. Follow these tips when painting over wallpaper to get a smooth painted surface:

  • Always follow your paint manufacturer’s instructions for proper application thickness and drying times between coats.
  • For the smoothest finish, apply paint in long, even strokes and maintain a “wet edge” so each stroke blends seamlessly into the next section.
  • Use a premium quality roller sleeve designed for smooth surfaces. This creates a more consistent finish.
  • Paint all walls in sections from top to bottom or in 4×4 foot squares so there are no visible start and stop points.
  • Inspect walls after each coat, under lighting, to check for any imperfections that require touch-ups. The color should look smooth and opaque after two coats.

Pro Tip: For added paint bonding power, consider applying a wallpaper adhesion promoter before priming or painting the prepared wallpaper walls. Adhesion promoters work to form a grip coating so the paint sticks tightly.

Step 5: Choose Interior Paint Sheen and Color

One of the great benefits of painting over outdated wallpaper is choosing a fresh new wall color. You can match the existing interior décor or go for a whole new look. Consider these tips when selecting wall paint color and sheen when painting over wallpaper:

Paint Sheen Recommendations by Room

  • Bathrooms/Kitchens: Semi-Gloss or Gloss Finish. These add wipe ability.
  • Bedrooms/Living Rooms: Eggshell or Satin Finish. Provides rich color and some subtle sheen.
  • Entryways/Halls: Satin or Semi-Gloss Finish. Stands up well to traffic and kids.
  • Ceilings: Flat Finish is perfect to hide ceiling imperfections

Choosing Wall Colors

Coordinate color with flooring, furnishings, and lighting fixtures. For a sense of expanded space, choose lighter cool tones like soft greens or grays. Warm earthy tones like tan, red, or orange feel cozy and inviting. Bold, dramatic colors make a statement but can overwhelm a room. Instead, use them as accent walls combined with neutral base wall colors.
