How to Get Dry Mortar Off of Porcelain Tile
- 1). Pour hot water over the dried mortar to help soften it.
- 2). Chip away as much of the dried mortar as possible using a wooden block. The block should be about 1/4 of an inch thick, 1 inch wide and about 6 inches long. Use moderate pressure when rubbing the wooden block over the mortar to remove as much as you can. Wipe up the tile with a rag to remove the loosened mortar.
- 3). Pour more hot water onto any remaining mortar. Moisten a nylon scouring pad with hot water and scrub the tile to remove more of the mortar. Wipe up the mess with a rag.
- 4). Repeat the process of scraping the mortar with the wooden stick, and then scrubbing with the nylon pad until no more of the mortar comes off. Dry the tile well with a rag.
- 5). Mix 1 gallon of warm water and 1 cup of sugar into a clean bucket. Pour the sugar solution onto any mortar that is still on the tile. Let it sit for two hours, and then scrub with the nylon pad. Repeat as necessary until all the mortar is gone.
- 6). Clean the porcelain tile with a commercial tile cleaner and soft cloth to remove any haze or residue that might be left from the mortar.
