Check your wallpaper edges and make sure there are no loose edges or seams. If there are, put a bit of wallpaper adhesive under these spots and edges with an artist's paintbrush and press down to adhere back to the wall. Let dry according to the directions on the adhesive.
Wipe down your walls with a damp sponge to remove all dirt, dust and old wallpaper glue at the seams. Let dry before proceeding.
Remove all the switch plates and outlet covers. Put them in a bowl with all of the screws so you don't lose them before it's time to reinstall them.
Feel the wall all over with your bare hands to find any dents or scratches that need to be repaired. Use a surface filler such as spackle and a spackle tool to fill in these small places if there are any. Let dry and use fine sandpaper to smooth out these spots. Wipe dust from the sanding with a cloth.
Tape off your window edges, ceiling edges and baseboard edges with blue painter's tape to keep paint off these surfaces. Place drop cloths on the floor.
Stir the primer with a wooden paint stirrer. Apply the primer to the walls. This makes the paint adhere to the wallpaper. Let dry for 24 hours, to ensure the primer is completely dry before painting. After priming, if there are any blisters in the wallpaper, slit them down the center of the blister with a utility knife, apply wallpaper adhesive under them, and press to glue the paper back to the wall. Let the glue dry. Wipe excess adhesive off with a damp cloth and let dry.
Stir the paint and apply to the walls. Let dry for 24 hours. Reinstall the outlet covers and wall plates. Remove the painter's tape from all the edges.
