6 Steps to Painting Over Wallpaper
So you’ve decided to go ahead and paint over your wallpaper. If that is the case it is important that you are very thorough in following this 6 step process. This will ensure the best results in the short term, and avoid cracking, bubbling, and peeling of the paint and wallpaper in the future.
Step 1: Secure the Wallpaper
Look for any areas of peeling, bubbles, or lifting. Use the adhesive to secure these areas. If these repairs are extensive. Stop and re-think if you want to move forward with painting without removing the wallpaper first.
Step 2: Caulking
Apply a bead of caulk along the top and the bottom of your walls at the point that the wallpaper meets the skirting boards and the ceiling. This will prevent the paint from seeping under the wallpaper which may lift it from the wall.
Step 3: Sand
Carefully sand the wallpaper seams making them less noticeable once painted over. You can also apply spackle or joint compound. Once dry sand it down to a smooth surface for painting.
Step 4: Cleaning
You must thoroughly clean your wallpaper. Removing all the grease and contaminants that will keep the paint from properly adhering. Use trisodium phosphate (TSP) for best results. However, you may get by just using soapy warm water. Allow plenty of time for the wallpaper to dry before moving to step 5.
Step 5: Priming
Once the wallpaper is dry, seal the wallpaper with an oil-based primer. Apply one coat to seal the adhesive of the wallpaper. This will protect it from moisture from the paint to prevent peeling and lifting.
Step 6: Time to Paint
You are finally ready to begin painting.
If you are using water-based paint, make sure your primer was applied very well. However, it is ideal to use oil-based paint to ensure that the wallpaper won’t be exposed to any moisture. After the first coat is dry, apply a second coat.
Choosing the Right Primer – Why Oil-Based?
Proper priming is critical for good results when painting over wallpaper. You will need to use oil-based primer to:
- Avoid moisture in it like latex water-based primer
- Prevent peeling and lifting
- Prevent staining from certain wallpaper adhesives and glue
- Block patterns on the wallpaper from showing through
Keep in mind oil-based primers will have a strong smell and take longer to dry. So make sure that you keep the room well ventilated while you are priming and painting. If that is an issue for you, you can try a shellac-based primer.
However, under no circumstances should you use a latex water-based primer.
Painting over Wallpaper If It Is Embossed or Textured
Painting over embossed or textured wallpaper is never recommended. In fact, if the pattern or texture is too deep then it is impossible.
That said if your pattern or texture is not deep you can try to paint over it. However, you will need to first use a heavy grade (1700 is ideal) lining paper to cover the wallpaper.
Lining paper will cover the imperfections of the wall and the patterns. Hang it like you would regular wallpaper.
But again, if the wallpaper is heavily textured, this method won’t work and the pattern will still show through.
Also, consider the time it takes to hang the lining paper.
At this point are you really saving any time over simply removing the wallpaper?
Painting Over Vinyl Wallpaper
Can you paint over wallpaper that is vinyl?
Put simply the answer is yes.
However, like with any other wallpaper must be in good condition and securely attached to the wall.
If your vinyl wallpaper is the new peel and stick kind, then you need to remove it. As it will not be able to hold the extra weight that wet paint will create. Ultimately it will just start peeling off on its own.
Tips for Painting Over Wallpaper
