Painting Over Wallpaper: Tips and Considerations

Many homeowners find themselves in a situation where they want to refresh the walls in a room but have wallpaper already attached. Is it possible to paint over wallpaper, and if so, how should one approach it?

Preparation and Considerations

Painting over wallpaper is indeed possible, but it requires proper preparation to ensure a successful and aesthetically pleasing result. Here are some key steps to follow:

1. Type of Wallpaper

The type of wallpaper you have can significantly impact whether it's feasible to paint over it. For instance, vinyl wallpaper or wallcoverings with a glossy finish may need to be sanded lightly to enhance the paint's adhesion.

2. Condition of the Wallpaper

Ensure that the wallpaper is in good condition. Any peeling, damaged, or loose areas should be repaired or removed before proceeding with painting.

3. Cleaning

Clean the wallpaper thoroughly to remove any dust, dirt, or grease that could interfere with the paint's adhesion.

4. Application of Primer

Using a primer specifically designed for wallpaper before painting is highly recommended. This primer will help seal the wallpaper and provide a better surface for the paint to adhere to. It's crucial in ensuring a professional-looking finish.

5. Paint Selection

Choose a high-quality paint that is suitable for the conditions of the room. For example, moisture-resistant paint is a good choice for bathrooms or kitchens where humidity levels are higher than in other rooms.

6. Painting Technique

Apply the paint using a roller for large areas and a brush for corners and edges. Multiple coats may be necessary to achieve even coverage. Be sure to follow the drying times recommended by the paint manufacturer to avoid premature re-coating.

Challenges and Alternatives

In some cases, painting over wallpaper might not be the most desirable option. Here are a few reasons why:

It can look tacky. Moisture from the paint can re-wet the wallpaper glue, causing the wallpaper to bubble up. The imperfections and seams of the wallpaper may become more visible.

Given these potential issues, the best course of action might be to remove the wallpaper entirely. While this might seem more labor-intensive, it ensures a smoother, cleaner surface for your next paint job. If you decide to remove the wallpaper, renting a steamer from a tool rental place can make the process easier.

There is an alternative to removing the wallpaper if you still want to save the existing surface. Some strong primers, such as Kilz oil-based primer, can be applied directly to the wallpaper. This primer is made to seal and prep the wallpaper for painting. However, it requires caution as it dries rock hard and should be handled with proper ventilation and protection.

Conclusion

Painting over wallpaper is a viable option, but it requires careful preparation and the right materials. By following the steps outlined above, you can achieve a professional-looking finish. Alternatively, if the wallpaper's quality is poor, removing it might be the best solution in the long run.
