Bathroom wall tiles are falling off

The whole brick is removed from the back without any cement, indicating that the brick and the cement layer are not bonded well at all, and the brick should not have been blistered for a long time before pasting. Your brick should be a floor tile, that is, a full tile processed, the weight is relatively large, this kind of brick on the wall itself is easy to fall, there are cracks in the cement, indicating that the cement mark is not up to standard, or there are holes in the wall vibration, etc. To sum up the above, the cement is not good enough, and the brick is too good.

You should find a tiler to rework it for you.

This brick is fully tiled. 600 minutes cut into pieces. This is also a method of paving that is mostly used now!

But there is a point. Because it is full tile. It has a water absorption rate <. In other words, it doesn't absorb much water, so it doesn't absorb much cement.

It has nothing to do with the seams of your cement. Nor does it have anything to do with master masons. This is the characteristic of tiles. No matter how good the master is, no matter how good the tile is, it can also be a whole piece of non-stick cement.

You don't use glass stickers. That's useless. You knock the old cement off. Use Shiyun glue or dry hanging glue to make up for it. You can call a master mason to do it.

Remember to install hardware pendants in the bathroom and use glass to drill flowers when installing sanitary ware. Otherwise, it will fall.

I am a professional ceramic tile and sanitary ware master.

Look at your picture, the wall tiles are okay like this, and the middle is slightly not full, which does not affect the falling off. It won't affect the side, and it's normal to be free. The texture of the cement is clear, indicating that the basic skills of the person who sticks the brick are enough.

The non-sticking bricks lead to the falling off of the bricks, which can only be said that the brick draught is not enough, and the full magnetic brick itself is difficult to draft. If there is looseness in the adjacent ones (the bricks are walking next to each other one by one), it may be that the bubble bricks are not enough, which is the fault of the teacher. If not, there should be only one situation, when the brick is not solidified, there is an external force.

In addition, there is another possibility that the wall is not wet, the wall is cement brick, hollow brick or foam brick, the draft is too large, affecting the solidification of the brick, and the calculation is wrong. (The moisture in the cement and the moisture in the tiles are sucked away by them...)

This kind of tile is actually floor processed, 80*80 cut into 80*40. It's no wonder that the floor tiles stick to the wall and don't fall off! It is necessary to shovel it all out and then paste it.

Selling tiles and selling colored glazed tiles need to be soaked in water before paving. to stick firmly. Your kind of tile is processed by floor tiles, floor tiles can generally be pasted without soaking in water, it is porcelain tiles or wear-resistant tiles, polished tiles, non-slip tiles and the like!
