I have a vacation rental home.  The doors to the bedroom and the bathroom have hollow inexpensive doors.  One of my renters broke a hole all the way through to the other side on both doors.  I think we have all seen this issue in our lives.  So, I filled the hole with spray foam and let it dry completely.  Then, I scraped it level to the door, and finished it with these tiles.  I did not have to replace the doors and it has a nice look.  The tiles are easy to cut with scissors.
