Should the bathroom on the first floor of the self built house be waterproof?

I often hear people say, "bathroom waterproofing must be done well", "it is waterproof", "waterproof if it is not done well, it will be a big trouble".

However, you may not know that in bathroom decoration, more than "waterproof must be done well." There are also some details that need to be taken care of.

Bathroom decoration details:

1. When doing circuit transformation, the bathroom must be left with the line of the mirror headlamp (this line does not cost much), and the mirror lamp is needed to shave or make up in the future, so that you can see more clearly.

2. The waterproof construction of the bathroom is not done well. It is very important to clean the base layer before waterproofing construction, such as small stones and soil lumps on the ground, etc., which must be cleaned before waterproofing. The waterproof construction floor and walls are fully painted.

After the waterproof layer must be dry, do a closed water test for 1-2 days, and no leakage is OK. 

3. Before doing bricklayer work, be sure to check whether the access port of each sewer pipe is tightened, if it is not tightened, it will definitely leak in the future, and there may be bad smell

4. After the bathroom floor tiles are paved, brush the cross-section of the floor tiles at the bathroom door to waterproof. The purpose of this waterproofing is to prevent the water in the bathroom from flowing through the underlay below the floor tiles to the outside of the bathroom door.

5. After the bathroom is tiled, before buying the toilet. Remember to use a ruler to measure the pit distance of the toilet bowl (the toilet pit distance is the distance from the center point of the toilet sewer pipe to the wall). ​

6. Don't underestimate the installation of the toilet, and don't think that the toilet is OK when you put it on. If the toilet bowl is not properly installed, there may be an overflow at the bottom in the future, and there may be an unpleasant smell. 

7. When installing the socket, special attention should be paid to the bathroom. Remember to install a waterproof box for the bathroom socket, otherwise there will be a safety hazard. Because the bathroom is a damp and enclosed space, people don't know where the water will splash when they take a shower and rub their backs. ​​

8. The door of the bathroom must not be equipped with a wooden door. Regardless of the quality of the wooden door, over time, the moisture in the bathroom will have a certain impact on the door or door cover. So it's better to choose a metal door, and it's cheaper than a wooden door.

In the decoration process, the waterproof construction of the bathroom is a very critical step, because the water consumption of the sanitary room is the most used place in the house, if the waterproofing is not done well, it will bring great inconvenience to the owner after moving in. Do the base leveling. Use polyurethanes, C, polymers, cement mortars, etc., similar to paints, when brushing waterproof for the first time.

The ground must be carried out in a dry condition. Make it a perfect fit. The base layer is firmly bonded, no cracks, no bubbles, and no falling off.

Repeat the waterproof coating for the second time, and the thickness after brushing is thick, this waterproof material works very well, and it is also environmentally friendly. The waterproof paint for painting the wall should be higher, and the painting height is about the same. In case of water seepage and leakage caused by bathing or large amounts of water in the future, the water injection test, the detection time needs to be one day and one night, so that the test must be repeated twice to achieve the effect of waterproof without leakage to be qualified.

How much does it cost to make a bathroom waterproof? Answer this question.

Bathrooms must be waterproofed.

If the waterproofing is not done well, it will leave a lot of problems and troubles in future life, such as the wall is damp and moldy, the wall tiles fall off and so on. More seriously, it will cause water, dampness and mildew on the exterior wall.

1. It is best to ask the decoration team to do a good job of cement mulch for the upper and lower water pipes of the bathroom, brush 10 20 cm of waterproof paint from the ground, and then redo the ester waterproof on the ground, plus the original waterproof layer, to form a composite waterproof layer to enhance the waterproofness. At the same time, the water pipe groove in the wall should also be waterproofed, and the waterproof layer around the hole must be carefully constructed when the pipe, floor drain, etc. pass through the floor slab during the construction process. Buried water pipes in the wall, so as to achieve a reasonable layout, lay water pipes are made of grooves larger than the pipe diameter, plastering in the groove is smooth, and then brush waterproof paint in the groove.

2. It is necessary to pay attention to the joints between the wall and the ground and the joints of the pipeline between the water and the water, which are the most likely places to cause problems. Moreover, if you need to replace the original floor tiles in the bathroom, after chiseling the original floor tiles, you must first use cement mortar to flatten the ground, and then do the wall waterproof treatment, so as to avoid leakage caused by uneven thickness of the waterproof coating. Be sure to clean the floor before waterproofing the wall.

3. The waterproof coating film is relatively smooth, therefore, before the cement mortar layer is paved with tiles, it should be sprinkled with sand and brushed to ensure its bonding strength. The shower position of the bathroom should be meter high, and it is okay to be 30cm high in the non-watering area according to the specification. However, if the bathroom area is not large, it can be made higher, which can ensure that water vapor and splashing water will not affect the wall, causing problems such as moisture and peeling on the wall.

4. Wall treatment is also very important. In the general bathroom waterproofing treatment, about 30 cm of waterproof paint should also be made on the wall to prevent water from penetrating the wall. However, if the wall of the bathroom is a non-load-bearing lightweight wall, the entire wall should be coated with waterproof paint.

If you have a two-fan shower screen in your home, paint both walls that are connected to each other as well. If you use a bathtub in your home, the wall adjacent to the bathtub should also have a higher waterproof coating than the top edge of the bathtub.

5. The seams should be brushed in place. The joints between the walls and floors of the bathroom and the joints between the water and water pipes and the floor are the most problematic places. During the construction, you must urge the workers to deal with these corners and corners, so the waterproof coating must be applied in place.
