In this article, let's take a look at the reasons and solutions for tiles popping up. 

Why Do Floor Tiles Pop Up?

The reasons for floor tile popping up are as follows:

1. The expansion gap reserved between the floor tile and the floor tile and the surrounding walls is too narrow! When the room temperature changes violently, the floor, cement layer, and ceramic tiles will expand and contract with heat. For example, if the gap is too thin and there is not enough space for the ceramic tiles to stretch, the ceramic tiles are easy to pop up. This is easy to happen in the north, but not in the South because of the high humidity and small temperature difference.

2. Cement and yellow sand were not mixed in the correct proportion when paving floor tiles. If the cement grade is low and the yellow sand is put too much, over time, the cement in the lower layer will not be able to adhere to the floor tiles, causing the floor tiles to tilt up.

How to Repair Pop-Up Tiles?

1. Check whether individual tiles or large areas pop up. You can knock the tiles. The tiles that sound empty are already empty, that is, the tiles have been separated from the cement layer. Such tiles are easy to crack if they are pressed down.

2. In the process of tiling, the emphasis is on being careful, which is a great test of the workers' attitude. In the process of tiling, the four corners of the tiles must be aligned. The significance of this alignment is not only to look neat with the naked eye, but also to use tools to measure, and finally get the exact answer. We try our best to lay the tiles on the same horizontal line, The gap size of the ceramic tile should be consistent, so it will look more beautiful.

3. After the tiles are pasted, the next thing to be done is pointing. Maybe everyone doesn't know much about pointing. Before pointing, it's better to clean up all the dust and other impurities in the tile gaps. After they are completely dry, you can start pointing. In this way, the pasted tiles are not only beautiful but also very convenient to clean. Therefore, it's profitable and harmless.

According to the above statement, there is a problem that we must pay attention to. That is, if we do not clean the cracks of ceramic tiles, the cracks will turn black after a short time of use. In this case, it will become troublesome and unsightly to clean them again. Therefore, when decorating the house, we should pay more attention to the tiling process. Before joining, we should clean up the tile gaps, which is very helpful for our later decoration. If we find someone from the decoration company to paste tiles, we should also communicate in advance without any omission Check whether individual tiles are popping up or large areas are popping up. You can knock the tiles. The tiles that sound empty are already empty, that is, the tiles have been separated from the cement layer. Such tiles are easy to crack if they are pressed down. Therefore, the pop-up tiles must be pried up and repaved. If there are a large number of empty tiles, it is simply repaved

Tips for Reinstallation

1. Saw the joint between the pop-up tiles and other tiles with a cutting machine (there will be a lot of dust during cutting, so it is necessary to keep adding water to the cutting machine.), Lift the tiles carefully, and the action must be light, otherwise, it is easy to cause the tiles to crack.

2. Scrape off all the cement mortar stuck on the edge of the ceramic tile. The cement layer under the brick shall be treated, and 1-2 cm shall be planed off and cleaned.

3. Evenly apply a layer of mixed cement mortar. The ratio of cement to sand is 1:3 for wall tiles and 1:2 or 3 for floor tiles. The cement grade of cement is 32.5. In addition, if white cement is used, 108 glue must be used, so that the cement and floor tiles can be closely bonded.

4. Pave and flatten the cleaned tiles, and then use the joint filler for reinforcement after the cement is completely dry, so as to avoid the phenomenon of floor tiles warping and cracking.
