Installing wallpaper on a textured wall can seem like a daunting task, but with the right preparation and technique, it is entirely achievable. The key to a flawless finish lies not in fighting the texture, but in understanding how to work with it. This guide will walk you through the critical steps to ensure your wallpaper adheres properly and looks stunning, regardless of the wall's uneven surface.
Before you even unroll a single sheet, you must assess the condition and type of texture present. Not all textures are created equal when it comes to wallpaper adhesion. A light stipple is different from heavy knockdown or popcorn textures, and each requires a specific approach. You need to determine if the existing surface is sound, free of dust, grease, and any loose particles that could prevent the adhesive from bonding.
Preparation is the Foundation of Success
The most crucial phase of this project is preparation. Skipping steps here will almost certainly lead to peeling or bubbling later on. You must create a smooth, uniform surface for the wallpaper to grip, essentially building a new "skin" over the old texture.
Smoothing the Surface
For moderate to heavy textures, applying a bonding agent or a primer specifically designed for difficult surfaces is non-negotiable. Products like Goo Gone Max Power or similar degreasers are essential for cleaning walls that have accumulated years of grime. After cleaning, a specialized bonding liquid will help the wallpaper adhesive stick to the tiny peaks and valleys of the texture, creating a unified bond.
- Thoroughly clean the wall with a degreaser to remove dust and oils.
- Repair any cracks or holes with a durable spackle or joint compound.
- Sand the repaired areas smooth once the filler has dried.
- Apply a bonding agent generously across the entire wall surface.
Choosing the Right Wallpaper
Not all wallpaper is suitable for textured walls. You must choose a material that offers some flexibility and forgiveness. While a heavy textured finish might look beautiful on a sample card, it can be difficult to align on a wall with irregularities.
Vinyl wallpapers are often the best choice for this application because they are durable, washable, and more resistant to moisture than paper. A textured vinyl or a grasscloth texture can help mask minor wall imperfections while providing the aesthetic you desire. Avoid very delicate materials like pure linen or silk for this specific project, as they offer no margin for error during alignment.
The Application Process
When it comes time to hang the paper, you must be meticulous with your measurements and alignment. Use a chalk line level to mark a perfectly vertical plumb line on the wall. This line is your true north, especially important because the texture will make it visually difficult to judge if the paper is straight.
Apply the adhesive to the back of the wallpaper using a notched trowel, ensuring even coverage. Carefully position the first strip against your plumb line, allowing a slight excess at the top and bottom to trim later. The texture will cause the paper to lift in spots as you smooth it, so use a smoothing brush or plastic smoother to press the wallpaper firmly into the nooks and crannies without tearing the material.
Trimming and Final Touches
Once the wallpaper is smooth, use a sharp utility knife and a metal straight edge to trim the excess paper at the ceiling and baseboard lines. Press the edge of the knife firmly against the straight edge to cut through the paper and into the slight seam between the wallpaper and the wall trim. This ensures a clean, professional edge that won't peel over time.
Finally, check for any air bubbles that may have been trapped during application. If you find one, carefully slice it open with a utility knife, smooth out the air, and apply a small amount of adhesive to the slit. Hold the slit closed with a tight strip of tape until the adhesive sets. With patience and attention to detail, your textured wall will become a stunning feature in your space.
