Before painting, check the condition of the wallpaper and if it can be painted over
Before painting over wallpaper in a bathroom, it is important to check its condition and determine whether it can be painted over. Start by examining the wallpaper to see if it is peeling away in large sections. If it is, removing it is a better option than painting over it. If the wallpaper is extremely dirty or mouldy, avoid painting over it as the paint won't adhere properly and mould will show through the paint.
Some types of wallpaper are not suitable for painting over, including fabric-backed vinyl, textured wallpapers, and coated peel-and-stick wallpaper. Painting over these types of wallpaper can cause more harm than good, as the paint will make it difficult, if not impossible, to remove the wallpaper later without damaging the walls.
If the wallpaper is in good overall condition and is made of paper or paper-backed vinyl, it is generally safe to paint over it. However, it is important to test a small spot to see if the wallpaper can be easily peeled off. If it can, it is better to steam it off entirely rather than painting over it.
Additionally, consider the number of wallpaper layers. If there are multiple layers of wallpaper, removing them can be challenging, and painting over them may be a better option.
Before painting, it is crucial to prepare the walls properly. Start by removing any loose or peeling sections of wallpaper with a utility knife, being careful not to cut into the drywall. Use a flashlight to identify loose areas, which are commonly found near doors, windows, light switches, and baseboards. After removing loose wallpaper, clean the walls with a damp cloth to remove dust and dirt. If the walls are greasy, clean them with a diluted trisodium phosphate (TSP) solution, being careful not to soak the walls to avoid loosening the adhesive. Allow at least 24 hours for the walls to dry completely. Once dry, apply a primer to the walls, using a paintbrush for the edges and corners and a roller for larger areas.

Use painter's tape to cover areas that will not be painted
Painting over wallpaper in a bathroom is a great way to give the space a fresh, new look without the hassle of removing the wallpaper. When embarking on this project, it is important to use painter's tape to cover areas that will not be painted. This is a crucial step to ensure a neat and professional finish.
Painter's tape, also known as masking tape, is designed to be easily removable without leaving residue or damaging the surface. It is typically made of thin paper and has a gentle adhesive that allows it to stick to a variety of surfaces, including walls. Before you begin painting, take the time to identify the areas that need protection. This includes areas such as baseboards, trim, door and window casings, and large shelves. Carefully apply the painter's tape to these areas, ensuring that the edges are firmly adhered to the wall.
The tape creates a crisp, clean line between the painted and unpainted surfaces. It prevents paint from bleeding onto adjacent walls, trim, or other areas that you do not want to be painted. This is especially important in a bathroom, where you may have fixtures, mirrors, or tiles that need to be protected from accidental paint splatters or drips. By taping off these areas, you can paint with confidence, knowing that your paint job will be precise and tidy.
Additionally, using painter's tape allows for versatility during the painting process. If you change your mind about the colour or finish, or if you decide to add a design element later, you can easily adjust the taped-off areas. Simply remove the tape from the sections you want to paint and apply tape to any new areas you want to protect. This flexibility is especially beneficial in a bathroom, where you may have fixtures or features that you decide to update or change during the course of your project.
Remember to press the tape firmly onto the wall to create a tight seal. Once the paint is dry, carefully remove the painter's tape by slowly peeling it back on itself at a 45-degree angle. This technique will ensure that you achieve a clean, crisp line and a beautiful finished look in your bathroom.

Cut away loose or peeling sections of wallpaper
Before painting over wallpaper in a bathroom, it's important to cut away any loose or peeling sections of wallpaper. This can be done with a utility knife or a putty knife, being careful to only cut through the wallpaper and not the drywall underneath. It is recommended to walk around the entire room with a flashlight held at a low angle to better identify loose areas. Typically, loose wallpaper is found near doors, windows, light switches, above baseboards, or around any type of trim.
After removing the loose wallpaper, the next step is to prepare the walls for painting with a primer. Start by cutting in the edges of the wall with a paintbrush and primer. Brush all areas that a roller cannot reach, which is usually about a 3-inch band of paint. Place a paint liner in the paint tray and mix the primer well. Then, fill the reservoir end of the paint tray with primer, saturating the roller cover without causing it to drip. Apply one layer of primer to the wall.
For any areas of wallpaper that were cut away, it is necessary to fill in the missing sections. This can be done with a thin swipe of drywall compound or joint compound, followed by sanding to create a smooth surface. It is important to sand vertically, not horizontally, and to avoid applying too much pressure to prevent abrading the wallpaper. After sanding, gently wipe down the surface with a clean, lint-free cloth to remove any dust or debris that could get trapped in the primer or paint.
Some sources suggest using a thin layer of wallpaper seam adhesive to reattach loose fragments of wallpaper before cutting them away. This helps to ensure a smooth surface for painting. After applying the adhesive, lift the areas with a putty knife, then cut and fill in with spackle or drywall mud. Once dry, lightly sand the area before proceeding with priming and painting.

Clean, repair and prime the wallpaper before painting
Before painting over wallpaper in a bathroom, it is important to clean, repair, and prime the surface. Firstly, examine the condition of the wallpaper. If it is peeling away in large sections or is extremely dirty, mouldy, or damaged, it is recommended to remove it rather than painting over it. If the wallpaper is in good condition, you can proceed with the following steps:
Cleaning
Start by cleaning the wallpaper to remove any dirt, stains, or residues. Prepare a cleaning solution by mixing hot water with a mild detergent or dish soap. You can also add a cup of distilled white vinegar to the mixture for a more effective solution. Use a sponge or cloth to apply the cleaning solution to the wallpaper, working in small sections and paying extra attention to areas with glue or adhesive residues. Rinse the sponge or cloth with clean water and go over the cleaned areas to remove any soap or detergent residues. Finally, allow the wallpaper to air dry completely before proceeding to the next step.
Repairing
Once the wallpaper is clean and dry, it's time to address any repairs. Use a utility knife to carefully cut away any remaining loose or peeling sections of wallpaper, ensuring you only cut through the wallpaper and not the drywall underneath. If there are any holes, cracks, or uneven surfaces, fill them with an appropriate filling material or joint compound. Clean the areas to be filled with a paintbrush or handheld vacuum to remove any loose debris or dirt. After applying the filling material, let it dry completely. You may need to sand the filled areas for a smooth finish and apply a second coat if necessary.
Priming
Priming is a crucial step to ensure good adhesion between the wallpaper and the paint. Choose a primer suitable for your surface—acrylic-based primers are commonly used, but specific surfaces may require alkyd or PVA primers. Apply painter's tape to protect areas that you do not want to paint, such as baseboards, trim, door and window casings, and fixtures. Cover the floor with a plastic sheet to catch any paint drips. Follow the instructions on your chosen primer and apply it to the wallpaper using a paintbrush or roller, ensuring you cover all areas, including edges and corners that may be hard to reach with a roller. Allow the primer to dry completely before applying a second coat if needed.

Use an oil-based primer to seal the paper before painting with water-based paint
Before painting over wallpaper in a bathroom, it is important to determine if painting over it is possible. If the wallpaper is peeling away in large sections, removing it is a better option. If the wallpaper is excessively dirty, the paint won't adhere properly, and if it has large mold spots, that mold will show through the paint.
If you decide to paint over the wallpaper, you must clean, repair, and prime it with multiple coats before it's ready for paint. To prepare the walls for paint with primer, tape off all areas that will not be painted, such as baseboards, trim, door and window casings, and large shelves. Then, use a utility knife to cut away any loose or peeling sections of wallpaper, being careful not to cut into the drywall.
Next, sand the seams and remove the dust. After this, use an oil-based primer to seal the paper. This step is crucial as it will prevent the wallpaper from bubbling up. The oil-based primer will also provide a smooth surface for the paint to adhere to. Allow the primer to dry completely before applying the paint.
Finally, you can apply your water-based paint. It is recommended to use a water-based paint over an oil-based primer as it will provide better adhesion and a smoother finish. Make sure to follow the specific instructions for your chosen paint, as some paints may require multiple coats or specific drying times.

Frequently asked questions
Yes, it is possible to paint over wallpaper in a bathroom. However, it is not as simple as just applying paint to the wallpaper. The wallpaper must be cleaned, repaired, and primed with multiple coats before it is ready for paint.
First, you need to examine the condition of the wallpaper. If it is peeling away in large sections, it is better to remove it than paint over it. If the wallpaper is dirty, the paint may not adhere properly, and if it has large mould spots, they will show through the paint. If the wallpaper is in good condition, clean the walls with a damp cloth to remove dust and dirt. Then, use painter's tape to tape off all areas that will not be painted, such as baseboards, trim, and door and window casings. Next, cut away any loose or peeling sections of wallpaper with a utility knife, being careful not to cut into the drywall. After removing the loose wallpaper, apply a primer to the walls.
It is recommended to use an oil-based or shellac-based primer, as these will block any patterns or glue on the wallpaper from showing through the paint. Oil-based primers can take longer to dry and have a strong smell, so a fast-drying option or a shellac-based primer may be preferable.
