Painted walls need to be smoothed out. Scrape away any loose paint, sand the edges smooth and fill any holes. Previously wallpapered walls need to be stripped: Mist the walls with a fine spray of vinegar and water using a hand held spray bottle or a garden sprayer. Keep the walls moist for about fifteen minutes and then scrape with a wide knife. Newly dry walled walls need to be primed.
2. Measuring and cutting the wallpaper
Take measurements from the skirting to the ceiling in several areas. Take the longest measurement and add 10cm to allow enough room for trimming at either the ceiling or skirting. If there is a pattern repeat please take this into consideration and add that to your total measurement. Now place the wallpaper on a work table and cut using a t-square or long ruler. Hold this cut piece up to the ceiling to make sure the pattern is right. Mark the back of the paper at the top with a “t” so you know which end is up and number the strips to lessen the chance of confusion. Now match up the pattern with the second strip and cut it using the same measurement. Continue cutting the number of strips that correspond with the width of the walls. It is a good idea to work on one wall at a time as opposed to the whole room.
3. Applying the wallpaper
Spread the paste onto the area of the wall you wish to apply the wallpaper. Use a paintbrush to apply the paste onto the wall. Press the top edge along the ceiling and slowly smooth the wallpaper down the wall. Smooth out and remove any extra paste that squeezes out at the sides with a damp sponge. If using paintable wallpaper wait until paste is completely dry, then use a roller to paint on required colour.
