Sometimes the best tool we can use in wallpaper removal is PATIENCE!!
Not all papers are the same. While one may come off in a timely manner. The next one could take much longer. In most of these cases it is a water issue. When working with heavier materials such as Grasscloth you must give it ample time to absorb enough water. With non absorbing paper where you must make holes. When steaming is necessary.
Sometimes it’s just a bad paper and a tough removal. In these cases patience IS your best friend!!
If you take your time and let your tools do their work, your task will be much easier.
