  • fire brick hearth

    I have some bricks that are uneven on the hearth and was wondering if anyone knew what the best way to level/plane those down . That being said after reading this forum every night until my wife takes the mac out of my sleeping lap I feel certain that many of you know the remedy. I await your response and appreciate each of you.

    Use a belt sander - I bought the cheap belts at Lowes.

      thanks would a grinder with diamond cup work as well?

        I guess that depends on the skill level - I found that my grinder tends to go where it wants. The sander is easier for me to control.

          Also depends on the size of the cup...small one will be very easy to dig in to the bricks...larger one would be easier to handle...but I would follow Les' recommendation...look at that beauty of an oven he built!!!

            Try a masonary grinding disc for your angle grinder rather than a diamond cutting blade, it shouldn't dig in so much and you should be able to operate it at a flatter angle.

              Some people are more at home with a belt sander but for myself I prefer a "square face" on a sander/polisher. Unlike a round disc it's just about impossible to cut a "smile" using it and you end up with a really flat surface. Sand paper by the sheet is much cheaper than by the belt too with a larger selection of grits.

                Thanks again to all of you . This is an amazing site and knowing that this much experience is around made it so much easier to jump off the ledge and start this project. I am not sure how you have time to post pictures as you go but I will catch up in that area soon.

                  Also, remember the factory surface of the firebrick is harder than the interior: I recommend only abrading the edges that actually are catching the peel, instead of trying to sand the whole floor.

                    I have a few bricks that are prouder than others.

                    Never got around to sanding them down. - with the herringbone pattern, I don't seem to have any issues with the peel catching any...

                    To me - I'd go with it and see if it becomes a problem before I'd fix it.
