You can replace a damaged Nitro Tile in the middle of the floor. To do this can seem tricky, but if fairly simple if you have the right tool. The easiest thing to use when trying to pull up a tile in the middle of the floor is a paint can opener. You would then place the opener on the male side of the tile and lift. You may separate a few tiles around, but that is ok. After it has been pulled up, you can then replace and finish your floor. If you don't have a paint can opener, then you can start by separating the row of tiles that the damaged tile is in. You won't need to remove those tiles, just would need to separate them. Once you get to the tile that you are trying to change out, you would follow the same instructions as if you used a paint can opener.
