How to do a good job of waterproofing the bathroom?

Floor and wall inspections Ground and wall inspection should be done before the bathroom waterproofing, only after leveling the ground and wall can you enter the next project, and then you must carefully observe the ground and wall, if there are decoration impurities, you must clean up. At the same time, it is necessary to check whether there are impurities in the drainage pipes and sewer pipes, and the impurities in these places should be cleaned up. Only in this way will it not affect the waterproofing of the bathroom, nor will it cause the problem of blockage in the bathroom.

Coating of waterproof paints After the waterproof paint is applied to the floor and wall, it is time to start the waterproof coating. When the bathroom is waterproofed, special attention should be paid to the waterproof treatment of the joints such as sewer pipes, light walls, and flues, and the waterproof function must be strengthened in these places.

The waterproof height of the wall should be painted to a height of more than 1 8 meters, so that even the shower will not cause the wall to be damp, and it will not affect the waterproof layer. After the waterproof paint is painted, wait until it is completely dry to carry out the closed water test, and block the water outlets of the bathroom before doing the closed water test, and then place about 2CM of water in the bathroom, and the closed water test time is 24 hours. When the waterproofing project is completed, the decoration garbage and some discarded tools in the bathroom should be cleaned up and recycled.

How do you make a bathroom waterproof? Let's find out.

Bathroom waterproofing needs to be painted with waterproof paint twice, the first waterproof coating needs to ensure that it is firmly combined with the base layer, and then brush the second time after the first paint is dry, and then carry out a closed water experiment after completing the brushing, and observe that there is no leakage before it is completed.

Brush the waterproof paint for the first time, ensure that the site is clean and dry before construction, the waterproof coating should be filled, and firmly combined with the base layer, no cracks, no bubbles, no falling off, the height of the orange brush is consistent, and the thickness should meet the requirements of the product. Brush the second waterproof paint, pay attention to the need for a certain time interval with the first waterproof paint time, and wait for the first coat of paint to dry before the second coat. When conducting the closed water test, the water at the highest point of the ground should not be less than 2cm, and it should be stored for at least 24 hours, and it will be completed only after observing that there is no leakage.

That's all for today's sharing, I hope it can help everyone.

Bathroom waterproofing is relatively simple, pay attention to the three-point selection of materials, seven-point construction.

Toilet recommended materials, flexible K11 mortar on the market, or acrylic construction steps:

1. Preparation before construction.

1. Leveling of the base surface (the base surface should be strong and smooth, to ensure that there are no obvious concave and convex and pits) 2. If there are defects or cracks on the base surface, the waterproof layer construction can only be carried out after the treatment is qualified.

3. Cleaning of the base surface (clean until there is no dust, no oil, no concrete release agent and other sundries) 4. Cleaning the base surface (the base surface is in a wet state, but there is no obvious water accumulation) 5. The base surface with oil stains should be scrubbed with 10% sodium hydroxide solution, and then rinsed with water.

Second, waterproof construction.

1. Product ratio (according to the product instructions, mix evenly without agglomeration) 2. Use "Sipof Plugging Spirit" to brush it thinly first.

3. The first roller coating 801 glue (use the roller to evenly coat once) 4. Strengthen the treatment of the parts (first paint the yin and yang corners, pipe heads, sewers, etc. to the arc) 5. The first waterproof construction (evenly painted horizontally until there are no loopholes) 6. The second waterproof construction (every 2-4 hours until the surface is just non-sticky, and the longitudinal brushing) Third, test the water.

1. Water test time (after the waterproof membrane is dried, test the water after about 24 hours) 2. Key points of water test (spray water on the wall for 20 minutes, water storage on the ground for 24 hours) 3. Check (if there is water seepage, repeat the construction operation).

With polyurethane, the construction is simple, there is no technology, brush a 3 change, it's almost the same, pay attention to the root of the pipe, brush more.

After choosing the waterproof material, follow the steps below:

The first step is to carefully chisel out a circular groove about 3 cm deep around the embedded pipe (such as the floor drain toilet drain pipe), and use flexible waterproof material to do the first waterproofing.

The second step is to lay the embedded pipes (such as various hot and cold water pipes to be laid under the floor tiles) and re-mortar leveling.

The third step is to do the second overall waterproofing after drying, the wall is not less than 30 cm, and the wall surface of the shower is not less than meters.

The fourth step is to make a waterproof protective layer after waterproofing and drying, and lay the floor tiles.

90% of the backwater phenomenon in the bathroom belongs to "not operating according to the construction standards", which is artificially caused: afraid of trouble and trying to save trouble, not using professional plugging materials or using construction that does not comply with the prescribed technical standards, and some even do not do the second waterproof coating work after leveling the construction department. Finally, it leads to water seepage in the middle layer (interlayer), causing unnecessary trouble.

(1) About the "threshold stone".

See the diagram below.

1. The threshold stone must not be made (water stop beam) below, and the threshold stone should be wet paved instead of dry paved, and at the same time, it is necessary to pay attention to hollowing and blistering, so it requires skilled and excellent technology.

2. The practice of laying floor heating (waterstop beams):

A- After determining the orientation, the length should be consistent with the door frame, and the floor heating insulation mat (blue) should be cut off at the width of 150mm; Or inform the site to reserve the space according to the specified size.

The insulation strips (telescopic strips) at 100mm on both sides of the B-door sleeve are removed, and then the waterproof beams are made of cement concrete. And it forms an integral connection pouring with the plain ground. Finally, brush the waterproof paint twice.

(2) About the marble water retaining strip in the shower room

See the diagram below.

1. First of all, the experience room is tested and determined that the original building foundation is waterproof. Then, under this premise, the builder should use "water leakage" to make the R corner of the bathroom floor wall corner and the entrance of the drainage pipe for 4 weeks before waterproof construction (remember to do waterproof coating construction); Reapply the waterproof paint to ensure that nothing is lost.

2. If the floor is grooved due to the displacement of the toilet, then first brush both sides of the waterproof in the slot, and then do the above work, and then carry out the waterproof coating work of the whole room again.

How to properly waterproof the bathroom?

1. Before laying bathroom tiles, the wall waterproofing work should be done, the general wall waterproof height is about 30cm high, if it is a non-load-bearing light wall, it is necessary to do waterproof treatment on the whole wall, at least 60cm high.

2. The choice of bathroom waterproof coating should meet the national standards, for the construction of bathroom waterproof coating, it is very critical to make the joint between the wall and the ground, and we must first do the arc corner, and apply the corners of the wall and the ground in place, so that there will be no water leakage.

After the treatment of the toilet base is completed, the waterproofing of the roll paper coating is taken as an example to introduce the polyurethane waterproofing practice.

1.First of all, the surface of the base layer of the waterproof layer must be painted, and the debris on it must be cleaned up.

2.Then the waterproof material is painted, and the wall must be kept flat when painting.

3.Finally, carefully paint the floor drain and window cracks of the bathroom, and wait for the waterproof layer to dry.

How to do toilet waterproofing work well? Bathroom waterproofing should be constructed in accordance with the standard process and process The effect is good Waterproof standard process flow (key points): Grassroots cleaning The wall root and the perimeter of the pipeline need to do a waterproof additional layer Painting Closed water test Waterproofing is a hidden project, is the top priority of foundation construction, landscape decoration reminds everyone to pay attention to the following points when accepting:

First, the waterproof layer on the ground should extend to the wall surface back 30cm, the waterproof layer of the wall in the shower or connected room shall not be less than 2000mmX1200mm, and the waterproof height of the bathtub wall shall not be less than 1400mm; Second, the waterproof layer of the wall needs to be brushed and then tiled, and the air defense drum should be affixed; Third, the ground waterproofing needs to be closed for 24 hours, and there is no leakage; Fourth, the whole brick wall must be painted with special tile adhesive on the back of the brick. How to do bathroom waterproofing work well, now do you know the answer?

1. Bathroom waterproof construction steps.

Step 1: You can use a slightly coarser cement to base the foundation first, and then brush the waterproof paint after the cement is dry. 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.
