Tiles are wet in winter.

Ceramic tiles are wet in winter, but in rainy season, the ground is very wet because of the high air humidity, which makes people feel very uncomfortable. Tile moisture regain mainly occurs at the bottom of the building, but it should also be analyzed and dealt with in detail, and then the relevant content of tile moisture regain in winter should be shared.

Moisture-proof tiles in winter 1 1. The reason of tile moisture regain.

1, seasonal factors

The moisture regain of ceramic tiles is that humid air with high temperature (relative humidity above 90%) meets the ground with low temperature, and the ground is smooth and does not absorb water, which is easy to produce condensed water on the ground (usually when the temperature is about 2℃). This happens mostly in the rainy season, with much rain, high temperature and high humidity. Once the climate turns fine and dry, the phenomenon of moisture regain can be eliminated.

2. Soil factors

The moisture regain of ceramic tiles is that the moisture in the foundation soil under the floor cushion rises due to capillary action, and the water vapor permeates upward, which makes the floor material wet and aggravates the deterioration of the whole indoor humidity. This kind of situation often happens all the year round and is difficult to deal with. In addition, there are reasons such as poor outdoor drainage and poor indoor ventilation. The surface layer in most parts of South China is mostly clay and loam. Capillary water level of clay can rise to 2 ~ 2.5m, and loam can reach1~1.3m.. When building materials with poor compactness are used as indoor floors, the capillary action will be enhanced, and the phenomenon of ground moisture regain will be more serious.

Second, the solution of tile moisture regain

1, rainy season

You can buy 10- 15 kg of quicklime. As for the container, cover it and put it under the bed or in the corner of the house. When the weather is wet, open the lid and close the doors and windows. But you can open the necessary transom. As quicklime is a good desiccant, it can absorb the water vapor in the air and convert it into calcium hydroxide, thus keeping the indoor air dry.

2, to regularly check the room may be affected with damp parts.

3, seepage wall brick

Silicone waterproofing agent can not only prevent water vapor from entering, but also make the wall breathable. If possible, you can spray moisture-proof liquid on the wall to form a moisture-proof layer.

4. Activities that are easy to generate steam at home.

Such as bathing, cooking, cooling clothes, etc. , will cause water vapor condensation, resulting in humidity. At this time, it is necessary to humidify in time, such as closing doors and windows, pumping out humid air with an exhaust fan, or mopping the floor and splashing water in time. In addition, desiccant can be put in the cupboard.

Inspection and treatment of moisture-proof ceramic tiles on wet ground in winter 2

1, check

First, check whether there are cracks on the ground, which is the main channel for groundwater to penetrate upwards. Cement mortar or monolithic concrete floor slab, generally with a width of 0.

Cracks exceeding 0.5 mm are visible cracks. Regular cracks usually appear along the longitudinal or transverse direction of the room, which is formed by shrinkage and cracking of materials. Check the ground again for empty drums. You can tap vertically along the ground with a wooden stick. If the tapping is free, then there is an empty drum.

2, cracks, empty drum processing

For regular cracks, V-shaped cracks should be chiseled, cleaned and sealed with asphalt ointment. If it can be baked with flame, the crack will be fully dried and the effect will be better. Generally, hair cracks are closed in a large area.

Where there is an empty drum, the surface layer should be knocked off, the cushion layer should be chiseled off, a cement slurry should be brushed on the cushion layer, and then the surface layer should be repaired and leveled with the same material.

3. Moisture-proof treatment.

After the local treatment of cracks and hollows, the surface layer should be fully moisture-proof and closed. The principle of treatment is to block the capillary permeation channel in cement mortar or concrete.

Generally, the method of brushing waterproof paint or waterproof agent can be adopted. Before painting, the surface should be scraped and cleaned, and two waterproof coatings should be painted. The first brush should be forced to penetrate into the capillary hole. After the coating is dried for the first time (generally about 24 hours), it is brushed for the second time to form an integral waterproof coating.

At the corner between the ground and the wall, paint should be brushed to the height of the wall skirting board.

After the original ground is moistureproof, make a new surface layer. The choice of new surface material should consider the high strength, wear resistance, moisture-proof ability, easy cleaning, practical and beautiful, and cement mortar surface can also be used.

Ceramic tiles are moisture-proof in winter 3. What are the tricks to solve the problem of ground moisture regain?

1. Close the window.

Because the weather is humid, closing the window properly can solve the problem of ground moisture regain, especially in the morning and evening, the humidity is more serious. In the afternoon, the weather is relatively dry, so you can open the window to bask in the sun and achieve the effect of dehumidification.

2, the ground spread moistureproof mat

Moisture-proof mats can be laid on the ground to block external moisture and achieve the effect of heat preservation and moisture prevention.

3. Disseminate waste newspapers.

For places where the ground is wet, you can spread waste newspapers, which can not only absorb the water on the ground, but also wipe off the water on your shoes, killing two birds with one stone.

4. Wipe the wooden floor with a soft dry rag.

You can wipe the floor with a soft dry rag. Close the window after cleaning, and never open the window, or it will make the floor wetter.

5. Salt water mopping the floor

You can use warm water and salt. After the salt is fully dissolved, you can mop the floor with salt water, wring it out as much as possible, and then drag it, which can play a moisture-proof effect.

6, quicklime moistureproof

Quicklime is a desiccant, which can absorb the moisture in the air and keep the indoor air dry. As long as you put quicklime under the bed or in the corner of the room, you can absorb the moisture in the air and play a role in moisture prevention.

Step 7 light candles

Candles can be lit, which can not only remove the musty smell in the room, but also reduce the humidity in the room and prevent the ground from getting wet.

8. Use air conditioner or dehumidifier.

Turning on the air conditioner or dehumidifier can effectively reduce the indoor humidity, keep the indoor air fresh and solve the problem of ground moisture regain.
