How to deal with moisture in floor tiles

Dampness returns indoors in spring because after winter, the temperature of indoor walls and floors drops day by day, and the indoor temperature rises slower than outdoors, causing moisture return in the bathroom, wardrobe, sofa and other places in the house. It can be avoided by putting some desiccant appropriately, so how to deal with the moisture in the floor tiles? What is the reason for moisture resistance in floor tiles? Let’s take a look below.

How to deal with the moisture return of floor tiles

The first is to minimize the temperature difference between indoor and outdoor. Before the "cold tail warm head" will appear "moisture return", use heat sources such as heaters and electric ovens. The device heats the room to a temperature equal to or slightly higher than the outdoor temperature.

Second, try to isolate the intrusion of warm and humid airflow. Pay close attention to weather changes. Once you find that the wind direction changes from north to south, you should close doors and windows in time. Indoor wardrobe and kitchen cabinet doors should also be closed tightly to reduce The entry of warm and humid outdoor air.

The third is to put some moisture-absorbing substances indoors. The more economical and ideal one is quicklime (lumpy lime). When the lime melts, it absorbs water vapor in the air and releases heat, which has an impact on the indoor environment. temperature effect.

The fourth is to use equipment for dehumidification. The air conditioner with dehumidification function should be turned on immediately; if possible, a moisture absorber (device) can be used to filter the indoor air for "dehydration", and at the same time, continue to heat the room.

Fifth, items that are susceptible to moisture and mildew should be sealed and stored before spring to isolate the air. If a desiccant can be put in, the effect will be better.

Sixth, the cold and warm air currents meet frequently in spring, advancing and retreating from each other. After the "return of tide" day, if the weather changes (turns to northerly wind), windows should be opened immediately to ventilate and disperse the moisture; if it is sunny, it will During the weather, clothes and bedding at home should be dried frequently to keep them dry.

What is the reason for the anti-humidity of floor tiles?

1. Seasonal factors

The relapse of moisture in ceramic tiles occurs when the moist air with higher temperature (relative humidity above 90%) encounters When the temperature is low and the ground is smooth and non-absorbent, condensation water is likely to occur on the ground (generally it will occur when the temperature is around 2°C). This situation mostly occurs during the rainy season, when there is a lot of rain, high temperatures and high humidity. Once the weather becomes clearer and drier, the return of moisture will be eliminated.

2. Soil factors

Dampness in ceramic tiles is caused by the water in the foundation soil under the ground cushion rising through capillary action, and the vapor water permeating upward, making the ground material moist and aggravating the overall Deterioration of room humidity conditions. This situation often occurs all year round and is difficult to deal with. In addition, there are other reasons such as poor outdoor drainage and poor ventilation in the room. The surface layer in most areas of the South is mostly clay and loam. The water level rise in the capillary pores of clay can reach 2 to 2.5 meters, while that of subclay can reach 1 to 1.3 meters. When building materials with poor density are used as indoor floors, capillary action will be enhanced, making the ground moisture return more serious.

In wet seasons, you can buy 10-15 kilograms of quicklime. As for the container, cover it and place it under the bed or in the corner of the house. When the weather is very humid, open the lid and close the doors and windows. However, necessary transoms can be opened. Because quicklime is a good desiccant, it can absorb water vapor in the air and turn it into calcium hydroxide to keep indoor air dry.
