    Hello! I am retiling our fireplace hearth myself. Removed old tile and need to prep for retiling with new porcelain tile.

    My question is how do I prep the old surface - old mortar that is on original brick.

    I don't want to grind the mortar down because renting grinder $$

    I do want to keep tiles as low as possible to the ground, so I don't want to use a backer board that will lift the tile at least .5 / .75 inches up requiring a " frame" made around tile.

    Can I just chisel out all possible remains of old mortar, and then use a self leveler like Henrys Patch and level to prep the surface and make it even and level? Then I apply new mortar?

    thank you in advance folks

    I also think you could probably knock off everything loose and crumbly with a 4 inch brick chisel and a ball been hammer.
    Or a long floor scraper, like for scraping up old vinyl tile.

    This one is 6 inches wide. They come in wider widths also.
    Whatever this did not scrape off, the multi tool could grind off with no massive cloud of dust.

    Do it by hand. And yes, then apply leveler if needed. There is very little walking traffic on a hearth so you will be fine.
