Waterproofing must be done with closed water test! Never listen to the workers, or the neighbors will come to you!

when designing home decoration, the first step is the construction of hydropower project. Many people know about waterproofing, but they don't know exactly what happened. When some people live, they will find water leakage. In fact, we didn't do a good job of waterproofing when decorating. So do you know about the closed water test in waterproofing? In any case, we must do the closed water test. Today, Xiaobian will tell you about waterproof things.

1. How to waterproof

1. Safety in summer decoration comes first

In summer, the temperature is high, the climate is dry, and there are many materials piled up on the construction site. From the safety point of view, the materials should be kept in the shade as far as possible to avoid the fire caused by the internal combustion due to the poor air circulation and high temperature.

In summer, materials should be piled up on the construction site as little as possible, so as to reduce the hidden dangers of accidents. In addition, electrical appliances and tools during operation should be kept at a distance from the materials as far as possible, and it is best to make a reasonable division between the working area and the material area when working with electricity.

2. Be diligent in ventilation to prevent pollution caused by decoration. Buy a house

In order to avoid being hurt during the high incidence of decoration pollution in summer, in addition to using non-toxic and less toxic decoration materials as far as possible, please invite a regular decoration company for construction, and also do a good job in ventilation and air purification of the decorated room. If conditions permit, make the room as ventilated as possible; If there are no conditions, indoor ventilation devices and air purification devices that can reduce indoor harmful gases can be selected.

3. Moisture-proof, waterproof and sun protection

Buying wood products in summer includes building main materials such as large core board, auxiliary materials such as white batten, internal corner line, door edge line, window frame line and skirting board under the wall, etc., all of which need to be tested for moisture content of wood products. In the building materials market, general wooden products franchise stores should have measuring instruments for wood moisture content. According to the national regulations, the moisture content of standard plates cannot exceed 12%. Experts suggest that when buying materials in the rainy season, you can choose dry materials appropriately. When the materials enter the market, they will be placed for a day or two to make it the same as the surrounding humidity, so it is more suitable to use.

in addition, the board should be protected from strong sunlight exposure; In case of high humidity in rainy days, moisture-proof and deformation-proof measures should be taken during storage. Don't put the board and wood in a room with direct sunlight. Exposure to sunlight will accelerate the aging of paint and glue decorated with wood products. We should also do waterproof work to prevent rain from causing wood products to expand and deform, or even become moldy, so we should pay special attention to it in our daily life.

4. Wallpapers and paints should be naturally dried in the shade

Paints and wallpapers are commonly used wall decoration materials. In spring, because the air is humid, in order to make the walls dry as soon as possible, open the doors and windows for ventilation. Summer is different, because it is dry, so wallpaper should be soaked in water before paving, and then painted with glue. If you want to open the doors and windows at this time and let the newly laid wallpaper blow through flow, the wallpaper will shrink and deform due to rapid dehydration.

5. Removing the musty smell

Latex paint often becomes moldy and stale in hot flashes because it dries slowly in decoration. In this regard, anti-corrosion coatings can be used. Of course, even if it is an anti-corrosion coating decoration company, the general method is to turn on the air conditioner to dehumidify and pump away the moisture in the air; Keep the furniture doors open and keep them ventilated. After renovation, we will encounter the problem that all kinds of smells will not go out, which will affect people's health. The suggestion of the decoration company is that putting more green plants after the decoration, or putting two or three lemons, oranges and bananas in the room, can achieve the effect of quickly deodorizing.

6. Don't paint in rainy days

Experts suggest that when painting wood products, whether varnish or mixed oil, remember not to paint them in rainy days. Please ask the construction team to do some other work first in rainy days, or even stop work for two days temporarily, and don't do painting work in rainy days.

7. Don't rush to repair seasonal problems

In spring, the air humidity is high, and there is more water in walls, floors and wooden furniture. In summer, the air gradually becomes dry. At this time, there may be some problems due to the change of seasons, different temperatures and humidity, such as the contraction of wooden floors and the increase of gaps between boards; There are gaps between the wall and the door frame because of different kinds of materials and different shrinkage rates; Cracking on the wall is a normal phenomenon in seasonal transformation. At this time, the water will continue to evaporate and the wall may still crack. You should wait until the moisture of the wall is suitable for the external climate to repair it again, so the effect will be better.

8. Radiators should be taken into account

Although you won't use heating in hot summer, you will feel the importance of heating in your future residence. Moreover, the home decoration project is non-repeatable, so whenever you decorate, you should take the replacement of heating into account. In the current home decoration, it has become popular to replace the traditional cast iron radiator with a new steel pipe radiator with good heating effect and beautiful appearance. However, you should greet the relevant departments.

2. Precautions for waterproofing

1. Try not to damage the original waterproof layer.

During the renovation, some bath facilities in the bathroom of second-hand houses will be added and various water supply and drainage pipelines will be rearranged or moved, which has seriously damaged the original waterproof layer of the building. However, the waterproof layer was not repaired or re-constructed, so that the problem was discovered only after leakage occurred.

2. Make the floor waterproof before laying the floor tile

Replace the original floor tile in the bathroom of the second-hand house. After chiseling the original floor tile, be sure to level the floor with cement mortar first, and then make waterproof treatment, so as to avoid the leakage of waterproof coating due to uneven thickness. Before waterproofing, be sure to clean the ground and brush it with waterproof paint for 2 to 3 times.

3, the wall should be waterproof

When the bathroom of the second-hand house is bathed, the water will splash on the adjacent wall. Without the protection of the waterproof layer, the next wall and the opposite corner wall are prone to moisture and mildew. So be sure to waterproof the wall before laying the wall tiles. In general, the wall should be waterproof with a height of 3 cm, but the whole wall should be waterproof with a height of at least 1.8 m for non-load-bearing light walls.

4. The water pipe groove in the wall should be waterproof

During the construction process, when pipes and floor drains pass through the floor, the waterproof layer around the holes must be carefully constructed. Water pipes shall be buried in the wall, and the layout shall be reasonable. All laid water pipes shall be made into grooves larger than the pipe diameter, and the plastering in the grooves shall be smooth, and then waterproof coating shall be painted in the grooves.

5. Do the water closing test and accept the waterproofing

After the waterproofing project is completed, seal the door and the drain, fill the bathroom floor of the second-hand house with water to a certain level, and mark it. If the water level does not drop significantly within 24 hours, the waterproofing will be qualified. If the acceptance is unqualified, the waterproof project must be redone as a whole before re-acceptance.

I read the small series and shared it with you. I believe everyone has an understanding of waterproof design. We must pay attention to the hidden work when designing the decoration. If we didn't do the closed water test, it wouldn't be worth our waterproof work, so whether the master is happy or not, whether the workers are willing or not, we must do the closed water test. Well, I'll share it with you today.
