Instructions
1. Remove the old wallpaper from your plasterboard. Peel away any loose corners or edges. If you don't own a wallpaper steamer, rent one from your local rental center. This tool makes short work of wallpaper removal by using warm steam to loosen the wallpaper adhesive. Run the steamer over the surface of your wall, according to the manufacturer's instructions. Lift off the loosened strips. Apply a second coat of steam to remove areas of stubborn paper.
2. Wash your stripped wall with a solution of vinegar and water, mixing 1 part vinegar with 2 parts hot water. Pour the solution into a spray bottle and spray the surface of your stripped wall until slightly damp, not wet. Too much moisture or excess pressure can cause the surface of your plasterboard to lift and peel. Lightly buff the plasterboard with a damp rag using gentle pressure. Dry the wall with a towel. Use a tack cloth to remove small particles of dust and lint.
3. Protect the surrounding walls, fixtures and ceiling with lengths of painter's tape. Cover the flooring and any nearby furniture or fixtures with a layer of plastic sheeting.
4. Apply your primer coat, also called your undercoat, with a long-nap wool paint roller. This applicator will apply a thick layer of acrylic primer, covering the taped seams and providing a slight texture to the surface of your wall. Use a 1-inch paintbrush to work the primer into the corners and areas too small for your paint roller. Let your primer coat dry.
5. Apply your first coat of acrylic wall paint. Use a satin or semigloss finish to help add a little depth to your walls. While flat paint can enhance some interior designs, a paint that reflects the light can help hide any uneven surfaces on your plasterboard. Use a medium-nap roller to apply the color coat to the interior section of your wall. Use the small paintbrush to apply the paint along the outside edges of your walls. Let the first coat dry completely, then apply your second coat.
