Wallpaper Over Wallpaper – Can I wallpaper over my current wallpaper? That actually depends on the type, style, and condition of your existing wallpaper. Preparation will largely vary among two main varieties of wallpaper: non-coated and vinyl-coated. If you take these guidelines into consideration, the approach need to be reasonably painless.
Wallpaper without vinyl coating is the only wallpaper that can guarantee good results. Accurate “paper-papers” are typically high end merchandise or items that are created overseas.
Homeowners can tell if it is a correct paper by using a sponge. Wet an inconspicuous area, and if there is a darkening all through the complete surface, there is no vinyl coating. You might also be capable to flake off or rub out surface inks. With coated papers, the opposite results are to be expected.
Another consideration is strikethrough. This is a condition where the original paper’s inks or pattern seem via the new paper. Bleeding of inks may possibly also happen. Each of these errors may take hours to months for the symptoms to show. Test hangings can assist in determining if either of these will be a dilemma, but as they can manifest over time, they are not an exact indication.

You must make each and every effort to eliminate a vinyl-coated wallpaper initial. The purpose for this is primarily based on the principle of adhesion. Wallpaper adhesives stick ideal on porous surfaces, and coated papers have zero porosity. Your new wallpaper will not have the same bonding capabilities as it would more than a effectively prepared surface. The other end of the spectrum holds correct as nicely. Paper applied to non-prepped drywall has also a lot adhesion and will lead to harm upon removal.
There is another problem that recently has turn out to be a main topic, and that concerns mold and mildew. Envision the mold and mildew invitation when you encapsulate wet adhesive amongst two layers of non-breathable vinyl. Aside from the lack of adhesion, you also generate the ideal atmosphere for mold development.
If your vinyl wallpaper is causing excessive harm during removal, you should carry out the very same sort of prep that you would for painting wallpaper prior to re-papering.
