Hi, Mary. You are in luck. There are many posts on this subject already on the board. You can do a search by going up to "Edit" and then "Find in top window" from the Message Board page. You then type in words to search for like "brick" or "fireplace" and the topics/thread where the word appears will be displayed. Keep clicking and checking and you will find plenty.
You probably will want to use Peel Away but this will be a messy job and you still may not get the results that you want. It depends on the brick.
