Before you start, read the instructions that come with the wallpaper. After this, measure the width of your wallpaper. Deduct approximately 5 centimetres from this figure, then use the tape measure to mark this distance out from the corner of the wall. From this mark, use the spirit level and pencil to run a straight line from the top of the wall to the bottom. This line is where the edge of your wallpaper will be. You need to allow the wallpaper to overlap onto the wall next to it, so you can cut it cleanly in the corner, after hanging it.
Get up on the ladder and line the end of the wallpaper roll up with the top of the wall. Also line the edge of the wallpaper with the straight line that runs down the wall. Now run your hand over it, so that it sticks to the wall. Step down from the ladder and unroll the wallpaper until the roll is sitting on the floor. Cut the wallpaper from the roll, below the wall.
Use the plastic wallpaper smoother to smooth out all of the bubbles and creases in the wallpaper. Work from the top of the wallpaper to the bottom. Make sure you smooth all of the wallpaper because it also helps it stick to the wall. Once the wallpaper is smooth, use the utility knife and straight edge of the smoother to trim the wallpaper in the corner and at the bottom of the wall.
Apply paste to the wall where your second sheet of wallpaper will hang, using the paint brush and roller. Apply the paste evenly and wider than the width of your wallpaper. Stand on the ladder holding the top of the wallpaper and line-up the pattern on it with the wallpaper next to it. Then follow the same process as Step 5.
After hanging the first two sheets of wallpaper, continue applying paste to the wall and hanging the sheets of wallpaper until you have covered the entire wall. Make sure the wallpaper matches the pattern of the sheet next to it and follows its straight line.
