Why Painting Over Wallpaper in a Bathroom Can Be Tricky
Bathrooms are known for their high humidity and moisture levels, which can pose challenges when painting over wallpaper. The combination of steam from showers, condensation, and even occasional leaks can create an environment that’s less than ideal for paint adhesion and long-term durability.
Potential for Mold and Mildew Growth
Painting over wallpaper in a bathroom can trap moisture, creating a breeding ground for mold and mildew. These microorganisms thrive in damp environments and can cause health issues, allergic reactions, and damage to your walls. While paint can provide a barrier against some moisture, it’s not always a perfect solution, especially if the wallpaper itself is already damaged or has trapped moisture.
Durability of Paint vs. Wallpaper
Paint, while offering a smooth surface, can be prone to peeling and cracking in humid environments. Wallpaper, on the other hand, can sometimes hold up better in a bathroom, especially if it’s specifically designed for high-moisture areas. However, even moisture-resistant wallpaper can become damaged over time, especially if it’s not properly installed or maintained.
Types of Wallpaper Most Difficult to Paint Over
- Vinyl Wallpaper: This type of wallpaper is often used in bathrooms due to its moisture resistance. However, it can be difficult to paint over because its smooth, non-porous surface doesn’t allow for good paint adhesion.
- Textured Wallpaper: The textured patterns and raised surfaces of this type of wallpaper can make it difficult to get a smooth, even paint finish. The paint may settle in the crevices, creating an uneven appearance.
- Wallpaper with a Shiny Finish: Shiny or glossy wallpaper surfaces can repel paint, making it difficult to achieve a good adhesion. The paint may simply slide off the surface, leaving you with an uneven and unsatisfactory finish.

It’s crucial to prep your wallpaper before painting. This step ensures that your paint adheres properly and creates a smooth, long-lasting finish. Let’s get into the nitty-gritty of how to prep your wallpaper for a fresh coat of paint.
Cleaning the Wallpaper
Before you start painting, it’s essential to give your wallpaper a thorough cleaning. This removes dirt, dust, and grime that can interfere with the paint’s adhesion.
- Use a damp cloth or sponge to wipe down the wallpaper. Avoid soaking the wallpaper as it can cause it to peel or bubble.
- If you have stubborn stains, you can use a mild detergent or wallpaper cleaner. Be sure to test the cleaner in an inconspicuous area first to ensure it doesn’t damage the wallpaper.
- After cleaning, allow the wallpaper to dry completely before proceeding to the next step.
Sealing the Wallpaper
Sealing the wallpaper is an important step in prepping it for painting. It creates a barrier between the wallpaper and the paint, preventing the paint from soaking into the wallpaper and causing it to bubble or peel.
- Use a wallpaper sealer, which is a water-based sealant that dries quickly and doesn’t affect the color of the paint.
- Apply the sealer with a brush or roller, ensuring to cover the entire surface of the wallpaper.
- Allow the sealer to dry completely before proceeding to the next step.
Using Primer
Primer is a key ingredient in achieving a smooth, even paint finish on wallpaper. It helps the paint adhere to the wallpaper and prevents it from bleeding through.
- Use a primer specifically designed for wallpaper. These primers are formulated to create a strong bond with the wallpaper and prevent the paint from soaking into it.
- Apply the primer with a brush or roller, ensuring to cover the entire surface of the wallpaper.
- Allow the primer to dry completely before proceeding to the next step.

Painting Techniques for Bathroom Wallpaper

Choosing the Right Paint
The key to successful bathroom wallpaper painting is selecting a paint that can withstand the unique challenges of this environment. Moisture, humidity, and the potential for mildew are all factors to consider.
- Moisture-Resistant Paint: This type of paint is specifically designed to resist water damage, making it ideal for bathrooms. Look for paints labeled as “moisture-resistant,” “damp-proof,” or “bathroom paint.”
- Mildew-Resistant Paint: Mildew thrives in damp environments, so choosing a mildew-resistant paint is essential. These paints often contain additives that inhibit the growth of mold and mildew.

- Even Coverage: Use a high-quality paintbrush or roller to ensure even coverage. Avoid leaving streaks or missed spots, which can make the finish look uneven.
- Drying Time: Allow each coat of paint to dry completely before applying the next. This will help prevent the paint from becoming sticky or uneven. Drying times vary depending on the paint type and the humidity level.
Preventing Peeling and Cracking
Painting over wallpaper in a bathroom requires careful preparation to prevent paint from peeling or cracking.
- Clean and Prime: Thoroughly clean the wallpaper with a mild detergent and water to remove any dirt, grime, or loose particles. Allow the wallpaper to dry completely before applying a primer. A primer will create a smooth surface and help the paint adhere better.
- Seal the Wallpaper: If the wallpaper is particularly porous or textured, consider using a sealant before painting. A sealant will create a barrier that helps prevent moisture from penetrating the wallpaper and causing the paint to peel.
- Use a Good Quality Paint: Choosing a high-quality paint formulated for bathroom use is essential. Look for paints with excellent adhesion and durability.
