Ceramic tiles become damp in winter

Ceramic tiles become damp in winter. During the rainy season, due to the relatively high air humidity, the ground is very wet, making people feel very uncomfortable. The phenomenon of ceramic tiles getting damp mainly occurs on the ground floor of residential buildings. However, ceramic tiles should be analyzed and treated in detail. Next, we will share the relevant information about ceramic tiles getting damp in winter. Ceramic tiles become damp in winter 1

1. Reasons why ceramic tiles become damp

1. Seasonal factors

Ceramic tiles become damp due to moist air with higher temperature (relative humidity of 90%) Above) When encountering a low-temperature, smooth, non-absorbent ground, 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 can be eliminated.

2. Soil factors

Tile moisture return is when the water in the foundation soil under the ground cushion rises through capillary action, and the vapor water penetrates upward, making the ground material moist and aggravating the entire 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.

2. Solutions to moisture return in ceramic tiles

1. In the wet season

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 cover 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.

2. Regularly check the parts of the room that may be affected by moisture.

3. Water-permeable wall tiles

should be coated with silicone waterproofing agent to prevent water vapor from entering and make the wall breathable. If possible, spray moisture-proof liquid on the wall to form a moisture-proof layer.

4. Activities that easily generate water vapor at home.

For example, bathing, cooking, wearing cool clothes, etc. will cause water vapor to condense and produce moisture. At this time, it is necessary to remove moisture in time, such as closing the doors and windows tightly, using an exhaust fan to extract the humid air, or using a mop to promptly mop the splashing water on the floor. In addition, a desiccant can be placed in the cabinet. Ceramic tiles become damp in winter 2

Inspection and treatment of damp floors

1. Inspection

First check whether there are cracks on the ground. Cracks are the main cause of upward penetration of groundwater. aisle. Cement mortar or solid poured concrete floor, generally width 0.

Cracks above 05 mm are visible cracks. Regular cracks usually appear longitudinally or transversely in the room and are caused by shrinkage cracks in the material. Then check whether there is a hollow drum on the ground. You can use a wooden stick to gently tap vertically along the ground. If the sound of the knock is hollow, there is a hollow drum there.

2. Treatment of cracks and hollows

For regular cracks, "V" shaped seams should be cut into them and the inside of the seams should be cleaned. , sealed with asphalt grease. If it can be baked with a flame to fully dry the cracks, the effect will be better. Generally, hairline cracks need to be sealed in large areas.

For areas with hollow bulges, the surface layer should be knocked off, the cushion should be chiseled, a layer of cement slurry should be applied to the cushion, and then the same material as the surface layer should be used to repair and smooth it.

3. Moisture-proof treatment.

After partial treatment of cracks and hollows, the surface layer should be fully moisture-proof and sealed. The principle of treatment is to block the capillary seepage channels in cement mortar or concrete.

Generally, the method of applying waterproof coating or waterproofing agent can be used. Before painting, first chisel the surface layer, clean it, and apply two coats of waterproof paint. Apply pressure during the first coat so that it penetrates deeply into the pores. After the first coat of paint has dried (usually about 24 hours), apply the second coat to form an overall waterproof coating.

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

After moisture-proofing the original floor, make a new surface layer. When selecting new surface materials, consideration should be given to choosing ground materials that are high in strength, wear-resistant, moisture-proof, easy to clean, practical and beautiful, and cement mortar surface layers can also be used.

1. What are the tips to solve the problem of moisture on the ground?

1. Close the windows properly

Since the weather is relatively humid, close the windows appropriately. It can solve the problem of moisture on the ground. Especially in the morning and evening, the moisture is more serious. In the afternoon, the weather is relatively dry. You can open the window to bask in the ground to achieve the dehumidification effect.

2. Moisture-proof mats on the ground

Moisture-proof mats can be laid on the ground. This moisture-proof mat can block external moisture and achieve insulation and moisture-proofing. effect.

3. Spread scrap newspapers

For places where the ground is relatively humid, you can spread scrap newspapers. This will not only absorb the moisture on the ground, but also dry the water on the shoes. Play the role of 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. After wiping, be sure to close the windows. Do not open windows, otherwise the ground will become even wetter.

5. Salt water mopping

You can add salt to warm water. After the salt is fully dissolved, you can use salt water to mop the floor. Wring it out as much as possible before mopping. This will help To achieve moisture-proof effect.

6. Quicklime is moisture-proof

Quicklime is a desiccant that can absorb moisture in the air to keep indoor air dry. You only need to put the quicklime in Under the bed or under the corner of the house, it can absorb moisture in the air and prevent moisture.

7. Light candles

You can light candles, which can not only remove indoor mildew, but also reduce indoor humidity and prevent moisture on the ground.

8. Use air conditioners or dehumidifiers

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