Are you fed-up of your existing wallpaper and feel like it’s time to renew your walls with a fresh coat of paint? However, does the effort involved in removing your existing wallpaper cause you much grief? The good news is that you can paint over existing wallpaper, especially if it is in proper condition, has been on the walls for several years, and shows no signs of adhesion failure. Moreover, by painting over existing wallpaper, you are saved the time and effort involved in removing the old wall covering, and can start painting quite quickly, i.e. after you follow a few easy techniques to prepare your wallpapered walls for painting. You can prepare and paint the walls on your own or contact professional interior designers Bristol if you reside there.
Observe the entire section of the wallpaper to ensure that it is properly adhered to the walls. Cut off any loose seams of paper and use wallpaper paste to glue down any loose edges. This will reduce the incidence of the paper falling off during the painting process. For portions of the wallpaper that have lifted off the wall, cut across with a razor knife and pull off the loose part. Remove switch-plates, nails and other wall fixtures, and mask off your baseboard.
Keep the ends of the wallpaper in place by applying a thin segment of caulk around the edges of the wall, baseboards, ceiling line, trim and joint seam where the paper meets the floor and ceiling. The caulk will not only help seal the edges, but keep the paper from peeling once the wall is painted.
If your wallpaper is heavily textured, cover it with a thin coat of joint compound such as spackle. The spackle will help smoothen out the surface so that the texture will not be visible through the coat of paint. Also remember to apply a thin layer of drywall mud on the seams of the wallpaper and lightly sand it down. This will prevent the seams from getting overtly visible.
Apply quick-drying oil or shellac primer on the wallpaper to create a strong bond for the wallpaper with the wall, as well as to prevent any stains that might be revealed. The primer will help to seal the adhesive within the wallpaper and keep it away from the moisture in the paint. Use a short nap roller to apply the primer and create a smooth surface on which you can paint.
Do not use water based primers or paints, as they will be absorbed by the wallpaper and will cause the paper to loosen off from the walls, bubble and peel away. When the paper loosens up, it will start to fall away, irrespective of whether you have applied paint over it.
Your wall is now ready to be painted. Apply at least two coats of paint to benefit from the best possible results. In the event that you notice the seams of the wallpaper showing through even after two coats of paint, lightly smooth it over with a fine emery board.
