How to Wallpaper Over Wallpaper

Why Wallpaper Over Wallpaper

Wallpapering over existing wallpaper can be a practical solution for rooms with multiple layers of wallpaper or when removing the current layer is not an option. It also saves time and effort compared to stripping off old wallpaper and preparing the wall from scratch.

However, wallpapering over wallpaper has its limitations and may not work for all type of wallpapers. For example, vinyl or textured wallpaper may not provide a smooth base for the new layer, and heavily patterned wallpaper can show through the top layer.

Additionally, if the current wallpaper is damaged or peeling, it’s best to remove it before applying a new layer as it can affect the final result and cause bubbling or wrinkles in the new wallpaper.

Needed Materials

Wallpaper:

Choose a wallpaper that is suitable for covering existing wallpaper. Vinyl or non-woven wallpapers are recommended as they are thicker and more durable, making it easier to hide imperfections in the base layer.

Adhesive:

Select an adhesive that is specifically designed for wallpapering over existing wallpaper. This type of adhesive has a stronger bonding power to ensure the new layer adheres well to the old one. It’s also important to follow the manufacturer’s instructions and mix the adhesive correctly for best results.

Tools:

  • Wallpaper Brush or Roller
  • Smoothing Tool (Such as a Plastic Spatula or Squeegee)
  • Sharp Utility Knife
  • Measuring Tape
  • Level
  • Pencil
  • Cutting Mat
  • Large Sponge or Damp Cloth for Cleaning Excess Adhesive

8 Step-by-step Guidelines on How to Wallpaper Over Wallpaper

Step 1: Prepare the Surface

Before applying the new layer of wallpaper, it’s essential to ensure that the existing wallpaper is suitable for covering. Begin by inspecting the current wallpaper for any damages, such as peeling edges, bubbles, or tears. If any issues are found, repair them using wallpaper adhesive or by removing and patching the problematic sections.

Next, clean the surface thoroughly to remove dirt, dust, or grease that could interfere with the adhesive bond. Use a damp sponge to wipe the entire wall, and allow it to dry completely. Make sure any old adhesive residue is smoothed out to avoid bumps or irregularities in the new layer. If the wallpaper is textured, consider applying a lining paper as a base layer to provide a smoother surface for the new wallpaper.

Step 2: Measure and Cut the Wallpaper

To achieve a professional finish, accurately measuring and cutting the wallpaper is crucial. Begin by measuring the height of the wall from floor to ceiling using a measuring tape. Record these measurements and add a few extra inches to the length for allowances, such as trimming around moldings and baseboards. Roll out the wallpaper on a flat surface and use the recorded measurements to mark where you need to cut.

Employ a level to ensure that your markings are straight and even. Once marked, use a sharp utility knife or scissors to carefully cut the wallpaper. Repeat this process for each strip, ensuring continuity in any patterns or designs so they align perfectly when applied. By carefully preparing each strip, you will avoid gaps or overlaps, achieving a seamless look.

Step 3: Apply the Adhesive

Once the wallpaper strips are prepared, it’s time to apply the adhesive. Begin by laying a strip of wallpaper face down on a clean, flat surface. Using a brush or roller, evenly apply a generous layer of adhesive to the back of the wallpaper, ensuring full coverage from edge to edge. Pay special attention to the corners and edges, as these areas are prone to lifting. If you are using a pre-pasted wallpaper, activate the paste by submerging the strip in water as per the manufacturer’s instructions.

Allow the adhesive to set for a few minutes, known as “booking,” which helps it absorb into the wallpaper for improved bonding. Be careful not to over-soak or let the adhesive dry out. Once booked, proceed promptly to position the strip on the wall, starting from the top and smoothing downwards, eliminating any air bubbles with a smoothing tool as you go.

Step 4: Apply the Wallpaper

Once the first strip of wallpaper is applied, repeat the process for the remaining strips, ensuring they are aligned and the edges are tightly butted together. Use a cloth or sponge to wipe off any excess adhesive that may have seeped out between seams. For corners or hard-to-reach areas, you may need to make slight cuts using a sharp utility knife and smooth overlapping sections with a spatula or squeegee.

The key to a seamless finish is to carefully match the pattern and continue this process until all strips are applied. When working with intricate or highly patterned wallpapers, it’s essential to be extra precise in lining up each strip for continuity.

Step 5: Trim Excess Wallpaper

Once all strips are applied, leave the wallpaper to dry for at least 24 hours before trimming any excess paper along the ceiling, baseboards, and moldings. Use a sharp utility knife and a straight edge as a guide for precision.

The wallpaper will continue to shrink slightly as it dries, so avoid trimming too close to the edges to prevent gaps from appearing later.

Step 6: Smooth Out Any Bubbles or Wrinkles

Once the wallpaper has been applied and any excess trimmed, it’s important to address any bubbles or wrinkles that may have formed. Begin by using a smoothing tool or a plastic spatula to gently press out any air bubbles, starting from the center of the bubble and moving towards the edges. Work slowly to avoid tearing the wallpaper. For more stubborn bubbles, you can use a pin to puncture a small hole in the center of the bubble and then press down gently to release the trapped air.

For wrinkles, gently lift the affected section of wallpaper and reapply, smoothing it down carefully. If necessary, apply a little more adhesive to ensure a smooth and secure finish. Make sure to clean off any excess adhesive using a damp cloth during this process to prevent marks. The goal is to achieve a flawlessly smooth surface, enhancing the overall appearance of your newly wallpapered space.

Step 7: Allow the Wallpaper to Dry

After all wrinkles and bubbles have been addressed, allow the wallpaper to dry completely before moving the furniture back into place. This could take anywhere from 24 to 48 hours, depending on factors like temperature and humidity levels.

Avoid touching or putting pressure on the wallpaper during this drying period to avoid damaging it.
