As a general rule, try not to paint over wallpaper. Most often I recommend removing wallpaper, so you can start with a fresh wall. If this is not an option, then there are many issues to consider before you paint over wallpaper:
- The seams may not lie down properly.
- Moisture from the paint could cause wrinkling, blistering or peeling.
- Paint adhesion may be minimal over a heavy vinyl.
- The texture from the wallpaper may telegraph through, causing a poor look on a solid wall.
How to Paint Over Wallpaper
Any of these things could cause a problem. For these reasons, I always recommend testing the system prior to taking on the entire job. A test can prevent so many issues from occurring. It is better to be safe than sorry.
Keeping in mind the points stated above (and if removal of the wallpaper is not an option), the first thing you want to do is to clean the surface. Then lightly sand the seams to make them as smooth as possible. The smoother the better. Ultimately, you want a clean, dry, dull, and sound surface prior to application.
Next, test a quick drying latex adhesion-promoting primer. There are many wallpaper primers out there. Check with your paint supplier to see the recommended system. Roman adhesives is a leader in this product category.
If the primer dries without lifting, blistering or wrinkling the seam or the paper, then the surface is ready to be primed and then topcoated with a good quality latex paint.
Note that the seams may be visible in some areas. Repair those areas as needed.
