refacing a brick fireplace
I want to use some ceramic tile to reface an old brick fireplace. I also plan on cutting out some of the old bricks as the fireplace dominates a small room.
1. Would it be better to use a circular saw and diamond blade or an oscillating blade as on the Fein multimaster to cut through the mortar? I may also need to cut a few bricks in half due to the pattern that exists in the brickwork.
2. Should I just go over the bricks with thinset or apply backerboard first. There should be a lot of grip on the bricks with all the surfaces at different angles. Backboard would probably give me a chance to make the tiles line up better with fewer cuts.
Thanks for all your suggestions.
