In this article, we’ll explore whether it is possible to put new wallpaper over the existing one and provide you with a comprehensive guide on how to do it effectively.
Considerations before Applying New Wallpaper:
1. Condition of the Existing Wallpaper:
Before layering new wallpaper over the existing one, thoroughly inspect the condition of the current wallpaper. If it is peeling, bubbling, or damaged, it is advisable to remove it entirely. Applying new wallpaper over a compromised base may result in an uneven finish, and it will also make future removal more challenging.
2. Type and Texture of the Existing Wallpaper:
The type and texture of the existing wallpaper are crucial factors to consider. If the current wallpaper has a smooth, non-textured surface, it offers a more suitable foundation for adding a new layer. However, if the wallpaper has a heavily textured or embossed surface, it may affect the adhesion and overall outcome of the new wallpaper.
3. Number of Existing Wallpaper Layers:
If you find multiple layers of old wallpaper on your walls, it is generally not recommended to add another layer on top. The additional weight and thickness can lead to structural issues and create an unprofessional-looking result. In such cases, it is best to invest the time in removing all layers of the existing wallpaper before proceeding with the new application.
Steps to Apply New Wallpaper over Existing Wallpaper:
1. Clean and Prepare the Surface:
Before starting any wallpapering process, it is essential to clean the walls properly. Remove any dust, grease, or dirt from the surface using a mild detergent and warm water. Rinse the walls thoroughly and allow them to dry completely before proceeding.
2. Smooth Any Imperfections:
Inspect the existing wallpaper for any bumps, ridges, or imperfections. Sand down any rough spots or irregularities to create a smoother surface for the new wallpaper.
3. Apply a Primer:
To enhance the adhesion of the new wallpaper, consider applying a coat of primer over the existing wallpaper. A high-quality wallpaper primer will help create a smooth base for the new layer and promote better adherence.
4. Measure and Cut Your Wallpaper:
Measure the height and width of the walls accurately before cutting your new wallpaper. Add a few extra inches to ensure you have enough length for aligning the pattern and trimming the edges.
5. Apply Wallpaper Paste:
Using a wallpaper adhesive or paste, apply a thin, even layer to the back of the new wallpaper. Be sure to follow the manufacturer’s instructions for mixing and application.
6. Hang the New Wallpaper:
Carefully align the pattern of the new wallpaper with the existing one on the wall. Smooth it out from the top to the bottom, removing any air bubbles or wrinkles along the way. Trim excess wallpaper from the edges using a sharp knife or wallpaper trimmer.
While it is possible to put new wallpaper over an existing layer, several factors need to be taken into account. Ensure the existing wallpaper is in good condition, has a smooth surface, and is free from multiple layers. Properly preparing the surface, applying a primer, measuring accurately, and using the right adhesive are crucial for a successful outcome. By following these steps and considering the necessary precautions, you can achieve a fresh, updated look without the hassle of removing the existing wallpaper entirely.
