When it comes to home improvement, there are numerous possibilities for transforming the look and feel of your space. One popular option is adding trim to walls, which can create a polished and decorative touch. However, if you already have wallpaper installed, you may wonder if it is possible to apply trim over it without removing the wallpaper entirely. In this article, we will explore the feasibility of applying trim over wallpaper and provide you with some expert insights on how to go about it.
Evaluating the Condition of the Wallpaper
Before deciding whether to apply trim over wallpaper, it is crucial to assess the condition of the wallpaper itself. If the wallpaper is old, damaged, or peeling, it is generally recommended to remove it before adding any additional layers such as trim. Applying trim over damaged wallpaper will not only compromise the final result but also make it difficult to properly adhere the trim.
Preparing the Wallpapered Surface
In cases where the existing wallpaper is in good condition and firmly adhered to the wall, you will need to prepare the surface before adding trim. Start by cleaning the wallpapered area thoroughly. Remove any dirt, dust, or grease using a mild detergent and water solution. Rinse the area with clean water to ensure that no soapy residue remains.
Next, lightly sand the surface using fine-grit sandpaper. This step helps to create a slightly rough texture on the wallpaper, ensuring better adhesion for the trim. Once the sanding is complete, wipe away any dust with a damp cloth and allow the surface to dry completely before proceeding.
Choosing the Right Trim
When selecting trim for application over wallpaper, it is essential to consider the type and pattern of the wallpaper. Generally, thin and lightweight trims work best in this scenario, as they are less likely to add excessive weight and strain to the wallpaper. Additionally, choose a trim color and style that complements the existing wallpaper, creating a cohesive and visually pleasing result.
Applying the Trim
To effectively apply trim over wallpaper, there are a few key steps to follow:
- Measure and cut the trim: Measure the length required for each section of trim, allowing a small overlap where necessary. Use a miter saw or a miter box with a hand saw to cut the trim at a 45-degree angle for clean and seamless corners.
- Apply adhesive: Apply a small bead of construction adhesive along the back of the trim, focusing on the areas that will be in direct contact with the wallpaper. Depending on the adhesive used, you may need to apply it to both the back of the trim and the wallpapered surface.
- Press the trim into place: Align the trim with the desired position on the wall and press it firmly into place. Use a level to ensure that the trim is straight. If needed, secure the trim with small finish nails, making sure not to damage the wallpaper.
- Fill and paint the trim: Once the trim is securely attached, fill any nail holes or gaps with a wood filler or putty. Sand the filled areas smooth and paint the trim to match your desired finish.
Applying trim over wallpaper is indeed possible, as long as the wallpaper is in good condition and properly prepared. By evaluating the condition of the wallpaper, preparing the surface, choosing the right trim, and following the correct application steps, you can achieve a stunning transformation for your walls. However, it is essential to note that removing the wallpaper before adding trim is generally the preferred method for the best and longest-lasting results.
