Begin by minimizing the chances of the paper falling by adding adhesive to loose pieces and replacing damaged areas.Continue Reading
Sanding down the wallpaper?s seams keeps them from being too noticeable. If the seams are tattered, Resene Popular Paint Systems advises sticking them down by applying glue to both faces and letting it set for at least 20 minutes. Then firmly press or roll them flat. To seal the edges and keep the paper from peeling later, a thin line of clear caulk should be applied around the perimeter of the walls at the joint seams where the paper meets the floor and ceiling.
Smooth out the surface of heavily textured paper so it doesn't show through the paint by covering it with a thin coat of spackle. To stop any holes in the wallpaper, first press in the surrounds with the handle of a putty knife so no lump is left on the surface.
Seal adhesives within the paper to keep them away from the moisture in the paint by first covering the entire surface of the walls with a coat of oil-based primer. Should small bubbles become apparent after the first coat of paint, cross cut them with a sharp blade and glue down the edges before applying the final coat. Since it's typically the moisture in latex paint that sometimes causes bubbles or peeling by loosening the wallpaper glue, be sure to paint over the wallpaper using only oil-based paint.Learn more about Home Maintenance
