Published in Wall Surface Preparation 6 mins read

Yes, applying wall texture over existing wallpaper is indeed possible and can yield successful results, provided the proper steps and precautions are followed.

The Possibility of Texturing Over Wallpaper

Many homeowners wonder if they can bypass the often daunting task of wallpaper removal when updating their walls. The good news is that it is often achievable. As noted in expert advice, "This task can be daunting, yet if done correctly, texture painting over wallpaper is possible and even enjoyable!" This highlights that while it requires attention to detail, the process can be successful and even satisfying. The key lies in understanding the conditions under which it can be done effectively.

Key Considerations for a Successful Application

Successfully applying wall texture over wallpaper hinges on thorough preparation and the right material choices. Before beginning any project, it is important to ensure you have the appropriate tools and materials for the job.

Wallpaper Assessment

The condition and type of your existing wallpaper are paramount. Not all wallpapers are suitable candidates for texturing over.

  • Adhesion: The wallpaper must be perfectly adhered to the wall. Any loose seams, bubbles, or peeling sections will compromise the new texture, leading to cracks, bubbles, or peeling in the future.
  • Condition: The wallpaper should be in good overall condition, free from significant tears, water damage, or mold. Extensive damage often necessitates removal.
  • Type:
    • Smooth, Non-textured Wallpaper: Ideal for texturing. These provide a stable, consistent base.
    • Vinyl Wallpaper: Often a good candidate as it is durable and can be cleaned easily. Ensure it's well-adhered.
    • Embossed or Heavily Textured Wallpaper: Generally not recommended. The existing texture can show through the new application or make it difficult to achieve a uniform new texture.
  • Cleanliness: The surface must be clean, dry, and free of dust, grease, or grime that could prevent proper adhesion.

Material Selection

Choosing the right materials is crucial for ensuring durability and a professional finish. This involves identifying the appropriate paint and texture products.

Material Type Recommendation Purpose
Primer/Sealer Oil-based or Shellac-based Primer: Specifically formulated to block stains and seal surfaces. Seals the wallpaper, preventing moisture from the texture compound from re-activating wallpaper paste and causing bubbles. Provides excellent adhesion for the new texture.
Texture Compound Pre-mixed Wall Texture or Joint Compound: Available in various consistencies. Creates the desired texture effect (e.g., knockdown, orange peel, popcorn, sand swirl).
Paint (Optional) High-quality Latex Paint: Eggshell, satin, or semi-gloss finishes are durable. Provides the final color and protective layer over the dried texture.

Essential Tools and Preparation

Beyond the main materials, having the right tools makes the process smoother and ensures better results.

  • Cleaning Supplies: Mild detergent, sponges, clean cloths.
  • Repair Tools: Wallpaper adhesive, putty knife for smoothing bubbles or re-gluing seams.
  • Application Tools: Trowels, rollers, texture guns, brushes, or sponges depending on the desired texture.
  • Protection: Drop cloths, painter's tape to protect floors, trim, and adjacent surfaces.
  • Safety Gear: Gloves, eye protection, and a mask if working with dusty texture compounds.

Step-by-Step Guide for Best Results

Follow these steps for a successful wall texturing project over wallpaper:

  1. Inspect and Prepare the Wallpaper:
    • Thoroughly inspect the entire wall for loose seams, bubbles, or tears.
    • Use wallpaper adhesive to re-secure any lifting sections. Smooth out bubbles with a wallpaper smoother or a plastic putty knife. Allow to dry completely.
    • Gently sand any raised seams or edges to minimize their visibility under the new texture.
  2. Clean the Surface:
    • Wipe down the entire wallpapered surface with a mild, non-abrasive cleaner (like a TSP substitute) and a damp cloth. This removes dirt, grease, and grime.
    • Rinse with clean water and allow the wall to dry completely.
  3. Apply Primer/Sealer:
    • Apply at least one coat, preferably two, of an oil-based or shellac-based primer/sealer. This is a critical step that seals the wallpaper, prevents bubbling, and provides a stable base for the texture.
    • Allow the primer to dry completely according to the manufacturer's instructions.
  4. Apply the Wall Texture:
    • Mix your chosen texture compound according to product instructions.
    • Apply the texture using your chosen method (e.g., roller, trowel, spray gun) to achieve the desired effect.
    • Work in small sections to maintain consistency.
    • Practical Insight: Practice on a scrap piece of drywall or a discreet area first to perfect your technique.
  5. Allow Proper Drying and Curing:
    • Texture compounds require significant drying time, often 24-48 hours, or even longer depending on humidity and thickness. Ensure it is fully dry before proceeding.
  6. Paint (Optional):
    • Once the texture is completely dry and cured, you can apply your chosen paint color. Two coats are usually recommended for best coverage and durability.

Benefits of Texturing Over Wallpaper

Opting to texture over wallpaper can offer several advantages:

  • Time and Labor Savings: It significantly reduces the time and effort associated with wallpaper stripping, which can be messy and physically demanding.
  • Cost-Effectiveness: You save on the tools and materials required for wallpaper removal and potential wall repairs needed afterward.
  • Surface Enhancement: It can mask minor wall imperfections that might otherwise require patching or extensive preparation.
  • Enjoyable Transformation: As mentioned in the reference, when done correctly, the process can be "enjoyable" as you see a dramatic transformation of your space.

When to Consider Wallpaper Removal

While texturing over wallpaper is often possible, there are instances where removal is the better, if not only, option:

  • Poorly Adhered Wallpaper: If the wallpaper is already peeling, bubbling extensively, or coming off in sheets, attempting to texture over it will lead to failure.
  • Multiple Layers: If there are several layers of wallpaper, the added weight of texture compound could cause them to delaminate.
  • Water Damage or Mold: Any signs of water damage, mildew, or mold indicate that the wallpaper must be removed to address the underlying issue.
  • Deeply Textured or Embossed Wallpaper: Applying new texture over an existing deep texture can result in an uneven or undesirable finish.

By carefully assessing your existing wallpaper and following proper preparation and application techniques, you can successfully apply wall texture over wallpaper, giving your room a fresh, updated look.
