Step 1

To paint over wallpaper in a bathroom properly, thorough preparation is required to get the desired results. The first step is to remove all items from the bathroom, such as soaps, medications, hygiene products, etc. Also, be sure to cover the drains, toilet, and bathtub to protect them. Finally, cover all electrical connections to prevent paint splatters you will have to remove later.

It gives the paint better adhesion when painting over the wallpaper. Follow the manufacturer’s instructions for mixing. The primer can be applied with a brush or roller.

If the wallpaper is torn or coming up at the edges and corners, apply some wallpaper glue or adhesive to fix these issues and make sure the bathroom wallpaper completely adheres to the wall before you begin painting. You can also use a sealing primer to help cover any irregularities there may be between the wallpaper and the wall.

Once the walls are clean and you have applied the sealing primer, let it dry for at least 2 hours.

Step 3

It’s time to start applying the first coat of paint to the wallpaper. Make sure the paint you choose is oil-based for extra protection against the dampness that is always present in the bathroom. Use a roller to apply the paint, so you will get an even coat of paint on the wall,

If you have the opportunity to use a paint sprayer, the results will be even better. If you think it is necessary, apply a second or even a third coat of paint. Let each coat dry for at least one hour before moving onto the next coat.

Step 4

The last step is to clean the bathroom. Once everything is dried, you can bring everything back into your bathroom.
