Water drops appeared on the wall of latex paint on the day of moisture regain.

In real life, going back to the south is a phenomenon peculiar to men. At this time, our room will become very humid, and water droplets will inevitably appear on the walls. Let's take a look at the water droplets on the wall of latex paint resurgence day.

On the moisture regain day, water drops appeared on the wall of latex paint, and 1 small water drops appeared on the wall, which need to be handled in time.

How to judge whether the wall is seeping or returning to alkali

Water seepage on the wall is characterized by water droplets on the wall, that is, water flows out from the wall. Generally, except for the problem of internal water pipes, this situation is more serious, and the wall should be remedied in time. Returning to alkali means that the salt in the deep layer of saline-alkali soil is dissolved by water and rises to the soil surface due to capillary action. In severe cases, a layer of white crystals will be formed.

1, without insulation layer

In the past, many residential walls had no insulation layer. In winter, the temperature difference between indoor and outdoor is large, so it is cold outside the wall and hot inside. Because of the high temperature of the inner wall, condensed water will form on the wall, which will lead to the wall being wet, and it is the whole wall. This kind of situation usually only occurs in winter, but it will be fine in summer, but the sequela is that many ugly mildew spots will be left, which will affect the beauty of the wall.

2. The water pipe on the wall leaks

The water leakage of the pre-embedded water pipe in the wall causes the wall to be wet. Generally, this happens near the toilet, or on the top of the house, or on the wall. Generally, there is leakage at the joint of embedded water pipes, including whether there is leakage in the water pipes in the walls at home and upstairs, and water seeps into the partition wall.

3, the wall back to alkali

Alkali-returning wall refers to the phenomenon that after the wall of a building is wet, water dissolves the alkaline substances in the wall into water, and with the evaporation of water vapor, the alkaline dissolved substances are brought to the wall and crystallized and solidified on the wall. That is to say, we can see that the wall has white hair, and seriously, we can see that the surface of latex paint is yellow and the wall skin bubbles and falls off. The main reason why the wall returns to alkali, commonly known as cement frosting, is that calcium hydroxide of cement products reacts with carbon dioxide in the atmosphere to generate calcium carbonate, which is deposited on the surface of concrete products.

How to deal with wall seepage

1, directly replace the water pipe or repair it.

If it is because of the water pipe, you can replace the water pipe, or temporarily repair it with the special tape for repairing the water pipe first. The specific operation method is: first close the valve and cut off the water supply, then open the faucet to a suitable position to release most of the pressure in the water pipe, and then tie the leaking part with special adhesive tape or seal it with epoxy resin glue.

Step 2 contact the hotel

Any problems involving the external wall should be reported to the property, and the property should contact the engineering department for maintenance.

3. Waterproof paint

Owners with water leakage at home can buy waterproof coating for plugging and paint the bathroom walls and floors themselves. The best way is to ask the decoration workers to solve it, which is more professional and effective. Or waterproof it again, it will be a little troublesome.

Water drops appear on the wall of latex paint on the day of moisture regain. 2 Close the doors and windows.

When you return to Nantian, you must close the doors and windows, especially those facing south and southeast, so as to avoid the invasion of outdoor wet air and aggravate the phenomenon of "bubbling" on the wall. However, you can't close the doors and windows all day. When the temperature is high in the afternoon, you can open the doors and windows facing north for about half an hour, which is breathable and moisture-proof.

Towel drying

When water drops appear on the indoor wall, they can be wiped off with a soft dry rag to avoid mildew on the wall for a long time.

Mail a newspaper

When the wall is dripping, you can stick an old newspaper on the wall, which can absorb the water drops on the wall. And when the newspaper is all wet, you can wring out the water and reuse it.

Turn on the air conditioner, dehumidifier, etc

After the water drops on the wall of South China Thailand are dry, dehumidifiers, air conditioners and fans can be used to help absorb the water on the wall.

Alcohol wiping

When mildew spots appear on the wall due to humidity, you can brush off the mildew spots with a (dry) toothbrush first, and then gently wipe them with a soft cloth dipped in alcohol, so as to dry the wall and prevent mold growth.

Water drops appear on the wall of latex paint on the day of moisture regain. Is moisture causing water droplets on the ceiling in the south sky?

When I returned to the south, the water dripping from the ceiling was formed by the condensation of water vapor in the air on the ceiling. The air in southern coastal areas is humid in spring and contains a lot of water molecules. During this period, the temperature began to rise, but the building was insulated, and its indoor temperature generally did not rise in sync with the temperature, and the indoor wall and floor temperatures were still low.

In this way, water molecules in the air will condense when they come into contact with walls and floors with low temperatures, forming water droplets to be adsorbed on indoor walls and floors. When water droplets condense to a certain extent, they will flow down the wall or drop from the floor due to gravity. This is also the reason why the ceiling of the southern coastal area will drip.

What should I do if the walls and ceiling are moldy after returning to Nantian?

1. The doors and windows of Huinantian are not closed properly. Excessive humidity: when the air humidity is close to saturation, when the water vapor adheres to and penetrates into the surface of the wall paint film for a long time, it is easy to induce the surface of the paint film to be moldy.

2. Check whether the external wall is cracked, which will also lead to mildew.

3, to check whether the upstairs residents have decoration, once the upstairs floor seeps, it will seep down, which will lead to mildew.

4. Poor mildew resistance of coatings: the materials used for decoration are not good. Due to the poor mildew resistance of the product, water vapor can easily penetrate into the inner layer of the wall, which leads to the easy breeding of mold.

How to solve this situation?

1, is it necessary to waterproof all of them? This can also be brushed, but the amount of work is large and the cost is expensive. It is suggested that waterproof putty powder has the same effect as latex paint with waterproof effect.

2. Or if necessary, shovel off the wall and ceiling and redecorate, and pay attention to the selection of high-quality heavy-duty primer and topcoat.

The method of preventing the wall from being damp when returning to Nantian

1, close the window in the morning and evening to reduce moisture.

2. Use desiccant and other products to absorb moisture.

3. Use air conditioner and dehumidifier.

4, timely check and remove the water vapor on the wall.

Treatment of slight mildew in Huinan sky wall

1. Wipe the painted wall with mildew-killing water, 84 disinfectant or bleached aqueous solution (diluted to 5- 10%) and quickly wipe the mildew spots. The method is to wipe it with an easy-to-wring rag or spray it with a small watering can after atomization.

2. Leave it for 24 hours and wipe it with water. A clean rag must be dipped in water and wrung dry before wiping. If it is moldy, you can wipe the solution again. In order to avoid mildew again, we should pay attention to thoroughly drying the wall.
