Put over the wallpaper.
Can you put wallpaper over tiles.
There are a few reasons why tiling over wallpaper is problematic mostly because you re risking your expensive tiling job on a surface where you re cutting corners to prepare.
If you are unsure you may have to cut into the wallpaper to see if there is another layer underneath.
If you want to increase the adhesive strength of wallpapers in bathrooms then you can also add some like 20 dispersion adhesive to your regular.
If you want the tiles to stay up for the long haul it s best to put in the hard work to remove the wallpaper according to popular mechanics.
Wallpaper if some corners are peeling just peel them off and install smart tiles over them.
You may want to apply a prep coat to the ceramic tile before hanging the lining paper but it should stick if you ve adequately prepared the surface.
This layer will provide a blank slate on which you can hang wallpaper.
You can even wallpaper over slick nonporous surfaces such as tile concrete block or synthetic laminate paneling.
No extra preparation is needed on a smooth surface.
The smooth ceramic tiles with small joints and grout lines are perfect for peel and stick smart tiles.
Okay now as the primer has dried you have the right to put the wallpaper to your bathroom wall.
However if there is more than one layer of wallpaper on your wall remove them.
As you have already cleaned and smoothened the tile covering the area now you need not panic whether your idea of putting wallpaper on the tile area will get appropriately executed or not.
Therefore if you know there is only one layer of wallpaper on the wall and it meets the considerations mentioned above you can wallpaper over it.
On many of these surfaces you ll first need to apply lining paper which is a blank wall covering that provides a smooth surface for regular wallpaper.
The best option is to use vinyl wallpaper.
Try covering the ceramic tiles with another material to create a new backsplash.
