Sometimes you are tired of looking at the old wallpaper and want to get rid of it for paint. Sometimes, it’s a case of painting over in a new home.
Whatever the reason, you have come to the right place to figure out how to do it without compromising the structural integrity of your bathroom. Here’s how you go about it.
Step 1: Cleaning the Walls
Get some trisodium phosphate, also known as TSP, to clean the walls. It is a strong chemical so you need to dilute it before you get started. Get a bucket of water and add the TSP to it. The measure is one-quarter of a cup of the chemical for every gallon of water. Use the manufacturer’s directions on safety warnings.
One of them is to wear protective gear and ventilate the room because the fumes are toxic. Get a sponge or a spare paintbrush and apply it to the walls. Then you wait till the TSP is dry.
After that, use a damp cloth or a rag to remove the chemical. If the rag is too damp, it will damage the wall and if it is too dry, you might not get the TSP off the wall.
This means when you apply paint, it will not stick to the walls effectively. So, find the right balance.
Step 2: Priming the Walls
You must make sure that the wallpaper is completely removed before you paint over. Otherwise, you will see that the paint will start to peel off the wall because it didn’t stick properly. That can be done by applying an adhesive to the parts of the wallpaper that are weak. This is usually near the ceiling or the floor. So, get cracking on that.
Alternatively, you can also use a primer-sealer combination over the wallpaper. This ensures that there is a surface to which the paint sticks well and minimizes the odds of the paint peeling. If you get an oil-based primer, you will be good. Water-based primer-sealers are not great because they don’t work efficiently with the texture of wallpaper.
Step 3: Let the Primer Dry
Before you proceed to the next step, which is painting the wall, you must make sure that the primer is completely dry. Each primer works in a different way so you must check the manufacturer’s instructions to see how long you must wait before you start the painting job.
Step 4: First Coat of Paint
Once you have peeled off the wallpaper entirely and added the primer and let it dry completely, you are ready to paint the wall. If you didn’t know it already, this is done in multiple coats especially because in this case, you are painting over wallpaper. We’ll tell you why in a minute.
Now, once again, oil-based paint is the best way to go about it. This is regardless of the kind of primer you chose to use on the wallpaper. The actual task of painting itself is the same as you would do with a regular wall. Using a paintbrush, cut the edges of the wall. Then you can get a roller and paint the rest of the wall.
If you are painting over wallpaper, you might need to cover up imprints of patterns that might be left behind. So, you will have to do multiple coats.
Step 5: Second Coat of Paint
Before you get to the second coat of paint, you must let the first coating dry completely. You might also want to think about sanding the wall even if it feels like a tedious job. If you get a power sander, your job will get a lot easier.
This way, you can get rid of imperfections before you get to the final coat and the finishing process. Check the paint can to see how long you should wait so as to make sure that the first coating is completely dry.
Once it is, paint the second or final coating. If you did it right, you have a beautiful, freshly painted surface in front of you.
Painting over the bathroom wallpaper is not a difficult process. It just needs a little bit of preparation. And by the way, be prepared to find missing sections or uncover other problems on parts of the wall when you get the wallpaper down.
Repairs and replacements during this process are not unheard of. Good luck and a happy painting expedition to you.
