What aspects should be paid attention to in the bathroom waterproofing project

1. The waterproofing of the kitchen floor should first be swept flat with cement mortar, and then brushed with flexible waterproof materials. The waterproof layer on the ground is brushed three times in order to better achieve the waterproof effect.

2. Try not to damage the original waterproof layer. In the process of renovating the floor, the waterproofing layer is very easy to break, and if it is not repaired in time, it is very easy to leak in the future. Therefore, it is necessary to pay attention to the protection of the waterproof layer during the decoration process, and it needs to be repaired in time if it is accidentally damaged.

After a few minutes, the waterproof mortar is dry, and the waterproof mortar is stirred with cement and sand to form a waterproof mortar, and the surface is smeared on the waterproof plain ash with a thickness of 8 mm.

4. The groove of the water pipe in the wall needs to be waterproof. In the process of waterproof construction, if there is a pipeline or floor drain that passes through the floor slab, the waterproof layer around the hole must be carefully constructed. The water pipe embedded in the wall needs to be reasonably laid out, and the groove should be larger than the pipe diameter when laying the water pipe, and the waterproof coating needs to be brushed in the groove.

5. The floor of the kitchen is often 1-2 cm lower than the living room, if the kitchen is flooded, it is unlikely to drain through the living room, so the flexible waterproof material should not only be coated on the ground, but also be painted to the wall 15 cm high to prevent water vapor from infiltrating the wall. In addition, the waterproofing of the corner of the wall also needs to be specially treated, in order to strengthen the waterproof performance, the joints of the lower part of the two walls need to make a one-centimeter-wide groove to apply waterproof materials, and the perimeter of the pipe can also be sealed and filled along the edge of the pipe with waterproof glue, and the waterproof process is completed completely.

6. The base layer of the waterproof layer of the coating should be firm, the base surface should be dry, clean, and smooth, and there should be no hollowing, loosening, sanding, dampness and peeling, and the yin and yang corners of the base should be made into an arc.

7. Before the coating is painted, a layer of substrate treatment agent compatible with the coating should be applied to the base layer, the coating film should be completed many times, and the coating should be carried out after the coating is dried and formed into a film, and the direction of the coating should be changed alternately during each brushing, and the width of the same layer of coating film should be 30 50mm.

1. Bathroom waterproof construction steps.

Step 1: You can use slightly coarser cement as a primer first, and wait for the cement to dry before brushing the waterproof coating. But in painting money, the ground should be flat and there should be no grooves. Water is then sprinkled on the ground to expel the gas from the small holes.

Step 2: Mix the powder and liquid material evenly, and brush the bubbles if there are bubbles when brushing the paint.

Step 3: When brushing the paint, brush it from the same direction, wait 1-2 hours, and then brush the second coat. When brushing the second layer, the direction of the brush should be opposite to that of the first layer, so that the best coverage can be achieved.

Step 4: You can brush it several times, which can increase the density and fill the gaps. Some people think that the more layers of waterproof paint the better, or even brush six or seven layers, but in fact, this is not good, the paint is too thick and easy to crack.

Step 5: Wait for one day before taking a waterproof test.

Step 6: When doing the waterproof test, you should first fight with your downstairs neighbor.

Say hello, then plug the drain, fill the ground with water, and wait an hour to ask your downstairs neighbor if there is a leak. If there is a water leak, the waterproofing layer should be rebuilt. If the waterproof test is qualified, it can be tiled.

2. Precautions for waterproofing in the bathroom.

1. In order to ensure that the bathroom floor is flat, it must be leveled with cement mortar, and then waterproof, so as to avoid leakage caused by uneven thickness of waterproof coating.

2. After leveling, when carrying out the construction of the waterproof layer, it is necessary to pay attention to fire prevention and waterproofing.

3. When doing waterproof construction, the floor drain, pipeline, and wall hole should be carefully inspected, and the root of the pipeline must be caulked according to the requirements during construction. 4. The waterproof treatment of the wall should also be noted, if the wall and the bathtub are adjacent, then the waterproof treatment height should be higher than the upper edge of the bathtub, and the shower should reach a height of 180cm.

5. Before doing waterproofing, pay attention to the correct position of the floor drain elevation.

6. To ensure that the sewer is smooth, the sewer pipes in the bathroom, including floor drains and toilet sewer pipes, must be kept unobstructed.

1.In the hydropower renovation, we must pay attention not to damage the original waterproof layer.

Generally speaking, as long as the quality inspection of the new house received by the decoration owner is qualified, the waterproof layer has been made, but many decoration owners will transform the layout of the bathroom and the water and sewage pipelines when carrying out water and electricity transformation, so consumers must emphasize to the decoration workers not to destroy the original waterproof layer when supervising the construction, if the original waterproof layer is destroyed as a last resort, it must be repaired in time, and even redo the waterproof project to ensure that there will be no leakage.

2.Choose the right waterproofing material.

The waterproof material recommended by the Ministry of Construction of the People's Republic of China is a one-component environmentally friendly polyurethane coating, mainly because this coating can tightly wrap the pipe and the ground, penetrate into the gaps, and will not shrink after drying, and is more suitable for small areas of houses with more pipes and gaps than rigid materials such as waterproof cement. The cost of materials per square meter of this kind of paint is about 50 60 yuan, which is the price that the general decoration owners can afford.

3.Waterproofing materials cannot be painted on rainy days.

In order to have a good waterproof effect, the waterproof coating must be painted three times, the drying period of the one-component environmentally friendly polyurethane coating is about 3 4 days, if the waterproof material is painted in a rainy day, the effect of the waterproof coating will not be very good.

4.Do a good job of waterproofing the ground.

Before laying floor tiles, it is necessary to do a good job of waterproofing engineering; After the tile is laid, it is necessary to ensure that the brick surface has a drainage slope (generally about 1% is appropriate), and the slope is towards the floor drain, which is conducive to wastewater discharge.

5.Do a good job of waterproofing the wall.

When the bathroom is bathed, it will splash water on the adjacent wall, and if there is no waterproof layer to protect it, the adjacent wall and the opposite corner wall are prone to dampness and mildew. Therefore, it is necessary to do a good job of wall waterproofing before laying wall tiles, and the wall should be waterproof with a height of 30 cm in the general waterproof treatment, but for non-load-bearing light walls, the whole wall should be waterproofed, at least to be meters high.

Precautions. After the waterproofing project is completed, for the sake of insurance, it is necessary to do the waterproof inspection, if the waterproof inspection is not qualified, it must not be improvised, and the construction team must redo the waterproof project, if possible, you can ask professional decoration personnel to help supervise the waterproof project.

Bathroom waterproofing practices:

1.Before the bathroom is renovated, it is necessary to carefully check whether there is leakage in the bathroom on the upper floor, and if there is, you should let the waterproof project upstairs be done before decoration.

2.When decorating the bathroom, if the original wall and floor tiles are removed and redecorated, regardless of whether the original waterproof layer has been made, the waterproof layer should be redone before the wall and floor tiles are repasted, and the waterproof layer of the surrounding side wall is 200mm high, and there is a bathtub part, and the waterproof layer should be able to spray all parts of the shower.

3.Waterproof treatment when the bathroom is not decorated: if the waterproof layer is not made before, the waterproof layer will be added according to the above method; If the waterproof layer has been made, it should be carefully checked to see whether the waterproof layer is in place and whether it is damaged, otherwise it should be repaired.

After the repair, the water injection test is based on the fact that there is no leakage and no moisture on the walls downstairs and around the building.

Bathroom waterproof precautions:

1. Do not destroy the original waterproof layer during hydropower transformation.

Generally speaking, as long as the quality inspection of the new house received by the decoration owner is qualified, the waterproof layer has been made, but many decoration owners will transform the layout of the bathroom and the water and sewage pipelines when carrying out water and electricity transformation, so consumers must emphasize to the decoration workers not to destroy the original waterproof layer when supervising the construction, if the original waterproof layer is destroyed as a last resort, it must be repaired in time, and even redo the waterproof project to ensure that there will be no leakage.

2. Choose the right waterproof material.

The waterproof material recommended by the Ministry of Construction of the People's Republic of China is a one-component environmentally friendly polyurethane coating, mainly because this coating can tightly wrap the pipe and the ground, penetrate into the gaps, and will not shrink after drying, and is more suitable for small areas of houses with more pipes and gaps than rigid materials such as waterproof cement. The cost of materials per square meter of this kind of paint is about 50 60 yuan, which is the price that the general decoration owners can afford.

Regarding the waterproofing of the bathroom, the precautions are summarized as follows:

1.The first thing to pay attention to when doing waterproofing in the bathroom is the choice of waterproof materials, it is recommended to use the kitchen and bathroom waterproof slurry, which is specially developed for the yin and yang angles that are easy to seep water between the kitchen and bathroom, the pipe, the sanitary ware, the floor drain periphery, etc., so the special materials are dedicated, the pertinence is stronger, and the waterproof effect is of course better.

2.The construction of waterproofing should be carried out in accordance with the requirements of the manual, the proportion of waterproof materials, the standard thickness and height of construction, etc., so as to ensure a good waterproof effect.

3.After doing a good job of waterproofing, it is necessary to do a good job of sprinkling and maintenance in the later stage, and places with direct sunlight need to be covered and covered.

4.The base surface before waterproofing must be cleaned, there can be no oil and dust, etc., and it must be sprinkled with water to moisten, but there must be no stagnant water.

5.After the waterproofing is completed, remember to do a 48-72 hour closed water test to check whether there are any leaks in the waterproof construction and whether the waterproof function is normal.

When doing waterproof construction in the bathroom, the base layer should be treated first. Remove the original decoration materials, clean up the floating soil and cement, first use cement mortar to level the ground, and then do waterproof treatment, requiring a smooth and dry surface. This avoids leakage of the waterproofing coating due to uneven thickness.

When paving the waterproof coating, it should be evenly painted, and there should be no missing brush, bulging and falling off, and the thickness of the waterproof coating layer should not be less than, otherwise it will affect the waterproof effect. During construction, pay attention to the waterproof dead corners, the joints between the wall and the ground, and the joints between the water and water pipes and the ground, which are the most prone to problems.

After the construction of the waterproof leakage layer in the bathroom, block all the sewers in the bathroom, build a 25cm high barrier at the door, and then pour 20cm high water into the bathroom. After 24 hours, check whether there is leakage on the surrounding walls and ground, if there is leakage, it needs to be repaired in time, and then do a 24-hour water test without leakage after repairing before entering the next stage of construction.
