It is far better
to remove wallpaper and residual adhesives before painting.
If not you risk a variety of problems from lifting and curling
to staining and uneven textures. It is sometimes however
necessary to paint over it. Here is how to handle either
situation. Wallpaper can be removed by peeling, soaking
and scraping, or steaming and scraping. Scrub off any glue
and rinse thoroughly. Any gouges or scratches can be patched
with plaster or filler, then sanded and dusted with a damp
cloth. Interior solvent-based or water-based stain-blocking
sealer should be applied prior to painting.
When painting over wallpaper begin
by checking for loose areas of paper and poorly adhering
seams. Re-glue these problem areas and then try a paint
test in an inconspicuous area of the room to make sure it
will look acceptable, making sure there is a seam included
in the test area. Apply a solvent-based stain blocking sealer
using ample ventilation and a respirator. Allow it to dry
overnight and inspect it to ensure there is no discoloration
and apply a second coat if necessary. Apply a finish coat
to the test area and allow it to dry. Matt finish paints
will minimise the texture of the underlying paper. Consider
applying a second coat and then evaluate the test area to
see if you will proceed with the entire room. |
