Although the ideal surface on which to hang wallpaper is a clean, primed and sized wall from which all previous wallpaper has been removed, we realize that is not always possible. While not ideal, it is sometimes possible to hang wallpaper over existing wallpaper, but if you go that route, be prepared to accept less than ideal results. To minimize potential pitfalls, take these precautions: 1. Make sure the wallpaper over which you install your new wallpaper is securely installed. The better the previous installation; the better chance of success. 2. Ensure that all of the seams over which you hang your new paper are completely flat to avoid obvious ridges that might show through. 3. Plan your first strip so that your new seams do not align with the old seams. 4. Test hang a strip and let it stay overnight to make sure the moisture from the new paper does not loosen the previous layer of wallpaper. 5. Before hanging over wallpaper, it is even more important to seal and/or size the existing wallpaper in order to create a surface that is easy to slide your paper into place and which will maintain adherence to the old wallpaper. 6. Finally, if you are installing a light colored paper over a dark or high contrast paper, use a specialty pigmented wallpaper primer to block the old pattern from coming through the new design.
