Some of the tiles in the bathroom are falling off, what causes it?

Personally, I think there are several possibilities:

1.The porcelain tiles should be soaked with water when they are attached to the wall, and your workers may have omitted this different process, resulting in poor adhesion.

2.Unqualified cement causes poor adhesion.

I'll tell you how to deal with it.

1。Knock down the loose brick and check whether the waterproofing is hollow, and cut the waterproofing to make it anew if it is hollow.

2。The bricks should be soaked with water first, and then taken out to dry (only moist feeling when touched by hand, no watermark prevails) and then pasted.

3。You can add construction 802 glue to the cement, and buy cement from a large factory. In this way, the cement quality is better.

4。Check whether the sand ash at the bottom is sand falling phenomenon, and there is only a knock point to do it anew.

1.Poor quality cement.

2.The ratio of cement mortar is too high.

3.The base layer of the wall is too smooth.

4.Tile paving is dry without soaking in water.

5.The placement time is too long.

6.The wall is caused by large vibrations.

7.The grout used in the brick joints is too poor.

It's been a long time, or the cement is not good when it was first laid! It is recommended to use some cement paving, and my home has also fallen off!

After a long time, it is mainly because there is water vapor in the bathroom and bath, as well as gas on the sewer
