Painting over bubbled wallpaper can be a daunting task, but with the right techniques and materials, it is possible to achieve a smooth, professional-looking finish. Bubbled wallpaper can be caused by a variety of factors, including poor installation, high humidity, or the use of low-quality wallpaper. Regardless of the cause, the end result is the same: an uneven, unsightly surface that can be challenging to paint over. In this article, we will explore the steps involved in painting over bubbled wallpaper, including preparation, repair, and finishing techniques.
Preparation is Key
Before you can start painting, it is essential to prepare the surface properly. This involves cleaning the wallpaper, repairing any damaged areas, and creating a smooth surface for painting. Proper preparation is crucial to achieving a professional-looking finish, and it is worth taking the time to get it right. Start by cleaning the wallpaper with a mild detergent and water to remove any dirt, grime, or grease. This will help ensure that the paint adheres evenly to the surface.
Assessing the Damage
Once the wallpaper is clean, assess the damage to determine the best course of action. If the bubbles are small and isolated, you may be able to repair them with a simple patching compound. However, if the bubbles are large or widespread, it may be necessary to remove the wallpaper entirely. Removing the wallpaper can be a time-consuming and labor-intensive process, but it may be the only way to achieve a smooth finish.
Removing the Wallpaper
If you decide to remove the wallpaper, start by scoring the surface with a sharp utility knife or a wallpaper remover tool. This will help loosen the adhesive and make it easier to remove the paper. Next, apply a wallpaper remover solution to the surface and let it sit for the recommended amount of time. This will help break down the adhesive and make it easier to remove the paper. Use a putty knife or a scraper to gently pry the paper away from the wall, working from one corner to the other.
Repairing the Surface
Once the wallpaper has been removed, inspect the surface for any damage or imperfections. If there are any holes or cracks, fill them with a patching compound and sand smooth. Sanding is an essential step in the repair process, as it helps create a smooth surface for painting. Use a fine-grit sandpaper to sand the entire surface, feathering the edges of any repairs to create a seamless transition.
Applying a Primer
After the surface has been repaired and sanded, apply a primer to the entire area. A primer is essential for creating a strong bond between the paint and the surface, and it can help to hide any imperfections or stains. Use a high-quality primer that is specifically designed for use on walls, and apply it according to the manufacturer’s instructions.
Choosing the Right Paint
When it comes to choosing the right paint for the job, there are several factors to consider. The type of paint you choose will depend on the surface you are painting, as well as the desired finish and color. For most interior walls, a latex-based paint is a good choice. These paints are water-soluble, easy to clean up, and dry quickly. They are also available in a wide range of colors and finishes, making it easy to find the perfect match for your needs.
Painting the Surface
Once the primer has dried, you can start painting the surface. Use a high-quality paintbrush or roller to apply the paint, working in sections to maintain even coverage. Start at the top of the wall and work down, using a “W” or “M” pattern to spread the paint evenly. This will help to prevent streaks and ensure a smooth finish.
Allowing the Paint to Dry
After the paint has been applied, allow it to dry according to the manufacturer’s instructions. This is an important step in the painting process, as it allows the paint to cure and harden properly. Depending on the type of paint you are using, this can take anywhere from a few hours to several days.
Applying Additional Coats
If the first coat of paint does not provide adequate coverage, you may need to apply additional coats. Make sure to allow each coat to dry completely before applying the next one, as this will help to prevent the paint from becoming too thick and uneven. It is also a good idea to sand the surface lightly between coats, using a fine-grit sandpaper to smooth out any imperfections.
In conclusion, painting over bubbled wallpaper requires patience, persistence, and the right techniques. By following the steps outlined in this article, you can achieve a smooth, professional-looking finish that will last for years to come. Remember to take your time and do not rush the process, as this will help to ensure a high-quality finish. With the right materials and a bit of practice, you can transform any room with a fresh coat of paint.

What causes bubbles to form under wallpaper?
Bubbles under wallpaper are usually caused by air pockets that get trapped between the wallpaper and the wall surface. This can happen due to a variety of reasons, including improper application of the wallpaper, excessive moisture, or uneven wall surfaces. When air gets trapped, it can cause the wallpaper to lift and form bubbles, which can be unsightly and difficult to repair. In some cases, bubbles can also be caused by the use of low-quality wallpaper or adhesive, which can break down over time and allow air to seep in.
To prevent bubbles from forming in the first place, it’s essential to ensure that the wall surface is smooth, dry, and even. This can be achieved by cleaning the wall thoroughly, filling in any holes or cracks, and applying a primer to create a smooth surface. Additionally, using high-quality wallpaper and adhesive can help to minimize the risk of bubbles forming. If bubbles do form, it’s crucial to address the issue promptly to prevent further damage. This can involve piercing the bubble with a needle and applying additional adhesive to reattach the wallpaper to the wall.
Can I paint over bubbled wallpaper without removing it?
While it’s technically possible to paint over bubbled wallpaper, it’s not always the most recommended approach. Painting over bubbles can help to conceal them temporarily, but it may not provide a long-term solution. The bubbles can continue to grow and expand, causing the paint to crack and peel. Furthermore, painting over bubbles can also make it more challenging to remove the wallpaper in the future, as the paint can bond with the adhesive and make it harder to strip.
However, if you still want to paint over bubbled wallpaper, it’s essential to take some precautions. First, make sure to clean the surface thoroughly to remove any dirt, grime, or moisture that may be contributing to the bubbles. Next, use a high-quality primer to help create a smooth surface and improve paint adhesion. When applying the paint, use a roller or brush to work from the center of the bubble outwards, applying gentle pressure to avoid pushing the bubble further into the wall. It’s also a good idea to use a paint with a high solids content, as this can help to fill in the bubbles and provide a more durable finish.
How do I prepare the surface for painting over bubbled wallpaper?
Preparing the surface for painting over bubbled wallpaper involves several steps. First, clean the wall thoroughly with a mild detergent and water to remove any dirt, grime, or grease. Next, use a putty knife or scraper to gently scrape away any loose or damaged wallpaper, taking care not to gouge the wall surface. If there are any remaining bubbles, use a needle to pierce them and apply additional adhesive to reattach the wallpaper to the wall. Finally, use a primer to create a smooth surface and improve paint adhesion.
It’s also essential to fill in any holes or cracks in the wall surface before painting. Use a joint compound or spackling paste to fill in the holes, and sand the area smooth once it’s dry. Additionally, if the wallpaper has a textured or embossed pattern, you may need to use a specialized primer or coating to create a smooth surface. By taking the time to properly prepare the surface, you can help ensure a smooth, even finish and a durable paint job that will last for years to come.
What type of paint is best for painting over bubbled wallpaper?
When painting over bubbled wallpaper, it’s best to use a high-quality paint with a high solids content. This type of paint is more durable and can help to fill in the bubbles, providing a smoother finish. Look for a paint that is specifically designed for use on walls and ceilings, and choose a finish that suits your needs, such as flat, eggshell, or semi-gloss. It’s also a good idea to use a paint with a built-in primer, as this can help to create a smooth surface and improve paint adhesion.
In addition to choosing the right type of paint, it’s also essential to consider the color and sheen. If you’re trying to conceal the bubbles, a darker color may be more effective, as it can help to hide any imperfections. On the other hand, if you want to create a bright, reflective surface, a lighter color with a higher sheen may be a better choice. Ultimately, the best paint for painting over bubbled wallpaper will depend on your specific needs and preferences, so be sure to read reviews and consult with a professional if you’re unsure.
Can I use a texture-hiding paint to conceal bubbled wallpaper?
Yes, you can use a texture-hiding paint to conceal bubbled wallpaper. This type of paint is specifically designed to fill in small imperfections and create a smooth surface. It’s usually thicker and more viscous than regular paint, and it contains special fillers that help to conceal texture and pattern. When applied correctly, texture-hiding paint can be an effective way to conceal bubbles and other imperfections, creating a smooth, even finish.
However, it’s essential to follow the manufacturer’s instructions when using texture-hiding paint, as it can be more challenging to work with than regular paint. Make sure to apply the paint in thin coats, allowing each coat to dry completely before applying the next one. Additionally, use a roller or brush with a thick nap to help work the paint into the texture and create a smooth surface. It’s also a good idea to test the paint on a small, inconspicuous area first to ensure that it doesn’t affect the color or finish of the surrounding paint.
How long does it take for paint to dry over bubbled wallpaper?
The drying time for paint over bubbled wallpaper can vary depending on several factors, including the type of paint, the temperature and humidity, and the thickness of the application. Generally, most paints will take between 1-3 hours to dry to the touch, and 24 hours to fully cure. However, if you’re using a texture-hiding paint or a paint with a high solids content, it may take longer to dry.
It’s essential to allow the paint to dry completely before applying a second coat or touching the surface. If you’re in a hurry, you can use a fan or a hair dryer on a low setting to speed up the drying process. However, be careful not to apply too much heat, as this can cause the paint to dry too quickly and potentially lead to imperfections. Additionally, make sure to follow the manufacturer’s instructions for drying times and recommendations for applying additional coats. By allowing the paint to dry properly, you can help ensure a smooth, even finish that will last for years to come.
Will painting over bubbled wallpaper damage the wall surface?
Painting over bubbled wallpaper can potentially damage the wall surface if not done correctly. If the bubbles are severe or the wallpaper is old and brittle, the paint can cause the wallpaper to lift further, leading to more extensive damage. Additionally, if the paint is applied too thickly or with too much pressure, it can push the bubbles further into the wall, causing damage to the drywall or plaster.
To minimize the risk of damage, it’s essential to take your time and work carefully when painting over bubbled wallpaper. Use a high-quality paint and apply it in thin coats, allowing each coat to dry completely before applying the next one. Avoid using too much pressure or applying the paint too thickly, as this can cause the bubbles to become more pronounced. If you’re unsure about the best approach or the condition of the wall surface, it’s always a good idea to consult with a professional painter or wallpaper remover for advice. By taking the right precautions, you can help ensure a smooth, even finish that won’t damage the wall surface.
