    As long as the glaze is not corroded, it can be cleaned, and it can be cleaned with some gasoline.

    If the black spots on the glaze of the brick surface are burned by sparks during welding, and the enamel of the epidermis has been destroyed, then there is no way. You can only get something to cover up, such as shoe polish, toothpaste, etc., but there is no gloss. If you knock it down and change the bricks, you have to replace the whole wall.

    There should be protective measures for workers during construction, and how can the process of tiling be done before thermal welding? You can find some relevant evidence to claim compensation from the construction worker. If it's a road guerrilla, you can resign yourself to your fate.

    It is the welding slag that falls on the tile, generally oxide, soak it with acid for a while, rinse it well, and use the toilet cleaner.

    It's okay, just wipe it off gently. Now just looking horrible, in fact, it generally does not destroy the surface of the tile.

Bathroom leaks can be waterproofed directly on the surface of the tiles. If the filling of the tile gap is incomplete, fill it with Merrill Lynch porcelain glue, and then use a stone tile waterproof guard to do waterproofing.

Because when the tiles are pasted, the tiles are soaked in water for a few hours in advance, so that the tiles are full of water, especially the tiles in the bathroom, if the soaking time is short, or there is no soaking, the tiles will absorb the water on the surface and the water in the cement, the surface color changes, and then it is easy to fall off after a long time, that's it.
