Wallpaper hanging checklist
What is currently covering the walls?
Will it need to be removed, or can it be covered over?
What is beneath the covering?
What is the temperature and humidity level of the room?
Are the corners, doors, and windows level?
What is the pattern repeat of the chosen paper?
Does the paper require paste, and if so, how much and what kind?
A professional wallpaper hanger will know the answer to all of these questions and many more, and will guarantee your satisfaction of a job well done.
