How to do the waterproofing of the bathroom yourself

I guess you can't do it well.

The toilet space of ordinary residential buildings is narrow, and there are pipelines passing through the floor slab, etc., so the coating is commonly used for waterproofing and rarely uses rolls.

material waterproofing. There are two common types of waterproofing coatings: synthetic polymers.

Polyurethane waterproof coating (polyester cloth, glass fiber cloth, etc. are required for corners, etc.).

Polymer modified asphalt.

SB S waterproof coating (need to add carcass reinforcement material polyester cloth, glass fiber cloth, etc.).

Asphalt-based waterproofing coatings are basically gone.

Polyurethane waterproof coating is generally practiced as follows:

1: The ground is facing the slope of the floor drain direction, cement mortar or bean stone concrete can be, but the surface should be smooth. The slope near the door is small, and the slope near the floor drain is large, so you can grasp it according to the specific situation.

2: The pipeline passes through the root of the floor slab to strengthen the waterproofing. After the pipe root building sealing paste is sealed tightly, and the cement is smoothed and the foot pads are smoothed, the glass wire cloth reinforcement layer is 1 or 2 layers when brushing the waterproof coating. The same measures are taken near the floor drain.

3: The wall is clean and flat, without floating ash and small particles, and the junction of the wall and the ground is wiped with small original corners or slope corners. Stick glass filaments when brushing waterproof paint.

cloth reinforced layer 1 2 layers.

4: The total thickness of the polyurethane waterproof coating film is required.

millimeters above. It can't be decided by the number of passes. Pipe roots, wall corner reinforcement layer.

Brush first, dry at room temperature for 4h, and then brush and scrape in a large area. There shall be no leakage and bubbling. Paint over a large area.

After 24 hours of curing, the next layer is applied.

Sand grains for easy later combination with cement mortar.

6: The waterproof layer on the ground should be painted out of the bathroom door.

300 wide. Waterproof floor waterproofing layer shall.

200 above the ground

The wall waterproofing layer of the bathroom with a shower should be 1800 meters above the ground (L8 recommends waterproofing all over the wall).

7: Do as requested.

Closed water test (closed water test method omitted).

8: There is a package riser practice (the package riser method details L8 old post).

It is recommended to do the waterproof and then do the riser, and then make up the waterproofing again, if the ground waterproof layer is not damaged, you can avoid the closed water test.

If it is a bad house, you just simply ask to use it, the developer who normally delivers the house has done waterproofing, otherwise it can't be delivered, and the lessor should also explain that if it is not waterproofed, otherwise it is not right to rent out the house that cannot be used normally to you, so you don't have to do it, use it directly. Personal opinion.

Has your bathroom been waterproofed before, if the waterproofing has been done before, then there is no need to worry about water leakage, and is your bathroom sunken? Because the sunken type needs to be backfilled again, it needs to be waterproof first!

Go to the decoration market to buy polymer tarpaulin and waterproof adhesive powder. There is an instruction manual for the rubber powder.

Just follow the instructions.

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.
