After installing underfloor heating in the house, a tile floor was chosen. When winter came to use the underfloor heating, the floor tiles blew up within a few days. Many warmers have reported this predicament on forums such as Zhihu and Xiaohongshu, and for a while, it has caused homeowners headaches and sadness. Is this a floor heating problem? How to avoid it?BODEN editorial next with you to understand.

What will cause the floor tile cracking? There are several reasons, as follows:

1、tiling cement grade is not appropriate

Floor heating backfill, backfill layer final properties have prescribed standards. Used as floor heating backfill cement, the general recommendation is that the standard is 325#. The larger the cement grade, the higher strength it has. It takes less time for the cement to harden. Underfloor heating requires more than just cement that has a short setting time. Because the time is so short, it also results in a high water content within the cement. In this case, once the floor heating is turned on, the water with sufficient weight evaporates, which can easily cause the floor heating decorative layer of tiles to crack, and the wooden floor may also arch and blacken.

2、the ground tiling does not leave a gap, or the gap is too narrow

Ordinary tile tiling distance, to 3mm-5mm is appropriate. "Seamless tiles" tiling distance, in 1-1.5mm. if less than this distance, the ground is likely to have problems. Workers sometimes do not follow the standards and do not leave enough gaps between the tiles when tiling. When the underfloor heating was turned on, the tiles were heated and expanded, so they built up pressure on each other. This leads to cracking, arching, and skipping tiles. If the tiles are tiled in accordance with the standard, there will be no problem.

3、the floor heating is too high when the temperature is turned on, too rapid warming

The water content of this indicator determines the floor heating backfill layer and the survival of the wooden floor. Water content is too high backfill layer and flooring, open floor heating, water evaporation is quite fast, cracking and other conditions will occur immediately. If you don't pay attention to this, there's no way to avoid the downfall of wear and tear, even if the floor tiles and flooring in your home are laid in a compliant manner.

The hidden danger of losing water too quickly must be dealt with in the first place.

Therefore, warm friends turn on the floor heating, to comply with the principle of the very beginning of low temperature, gradually increase the temperature. Let the moisture in the backfill layer slowly evaporate, and the floor tiles step by step to adapt to the temperature change. Preserve the results of the decoration of the interior.

Not only the floor, but also all kinds of furniture in the home have to adapt to the temperature before escaping from failure.

Dry floor heating also needs to be warmed up slowly, first to a value of only 5°C above the room, and then to the desired temperature in 12-24 hours. After reducing the moisture content of the floor, the next time the heating is needed, it can be turned on immediately to raise the temperature to normal.
