What are the nodes of waterproofing in indoor toilets?

Toilet waterproof construction process process.

First, the construction process: grassroots cleaning, leveling layer construction, detail additional layer construction, the first polyurethane waterproof construction, the first closed water test, the second polyurethane waterproof construction, the second closed water test, finished product protection.

Second, the construction process: 1Before the construction of the waterproof layer, the floating ash on the surface of the base layer should be cleaned up.

Use a broom to sweep away dust, sand and other debris. In particular, the pipe roots, floor drains and drains should be carefully cleaned with a brush. If there is oil stain, it should be brushed off with a wire brush and sandpaper.

The surface of the base layer must be flat, and the depression should be leveled with polymer mortar. 2.Before the construction of the leveling layer, the first thing to do is to review the 50 lines of the bathroom to ensure that the elevation is accurate.

After watering and wetting the base layer, evenly sweep the cement slurry (water-cement ratio, mixed with 6% construction glue) on the base layer, and spread the mortar with sweeping, the cement mortar used in the mortar is 20mm at the thinnest point and find the flooding to the floor drain, and the slope of the flooding should be controlled at 2%. The yin corner of the bathroom wall and the ground should be made into an arc, with a diameter greater than 100mm, and the root of the water pipe, sewer pipe, floor drain, etc. of the screed layer should be made into an arc shape, and the yin corners of all walls should be rounded with a radius of 50mm, and the yang corners should be rounded with a radius of 10mm. 3.

Detail additional layer construction with a brush dipped in the stirred polyurethane evenly painted on the weak parts that are easy to leak such as pipe roots, floor drains, yin and yang corners, etc., shall not be missed, and evenly brushed within 150mm around the pipe root and 150mm above the ground height. The width of the polyurethane additional layer at the yin and yang corners is 300mm. The thickness of the additional layer should be.

The waterproofing of the coating film at the junction of the ground and the corner of the wall is higher than the first polyurethane waterproof construction of the completed surface, and when the additional layer of polyurethane is not sticky, the first layer of coating film construction is carried out, and the mixed polyurethane waterproof coating is evenly brushed on the surface of the base layer that has been coated with primer with a brush, and the thickness should be uniform.

In the first step, if the base layer is the soil surface, the plain soil should be compacted first, and then the one-step Panax notoginseng ash soil should be made, and then a layer of concrete cushion should be poured; If it is a concrete floor slab, you can directly make a screed.

The second step is the construction of waterproofing.

The third step is to do a closed water experiment.

The fourth step is to make a protective layer for waterproofing.

The fifth step is to carry out the construction of the surface layer of bricks.

The sixth step is to carry out a second closed water test.

Pipes, floor drains, doorways, dark corners, etc.

1.Pipes are blocked through the floor slab, 2Floor drain port plugging node. 3.Wear the toilet flue waterproof node. 4.The yin and yang corners of the wall roots.

Bathroom leakage can be big or small, seeping into the home, leaking downstairs, it is a very troublesome thing, so many people are very annoyed.

1.Waterproof floor drain:

1).At the floor drain, according to the form of the floor slab and the design requirements, the floor drain elevation is determined, and the flooding is found upward.

2).After the riser is positioned, the joints around the dry floor slab are blocked with 1:3 cement mortar, and when the joints are larger than 20mm, they are blocked with 1:2:4 bean stone concrete. Vibrate compactly.

3).The cushion of the toilet and bathroom is 2% slope to the floor drain, less than 30mm

Use. 5).The floor drain pipe fittings are installed on the surface layer, and the ground around them is facing the floor drain.

2% slope, find 3% 5% slope within 50mm range, so as to drain water.

2. Sewer pipe.

1).The bottom of the waterproof layer of the pipe root is sealed with 10mm 15mm building sealing paste.

2).50mm around the root of the pipe, at least 50mm above the ground

3).The riser is located against the wall or corner, and the outward slope is 5%.

4).The waterproof layer should be rolled up at a height of not less than 20mm, and at the same time intersect with the sealing material around the pipe root, as shown in the figure below

3.Casing:

1).Pipe root casing pipe under the waterproof layer.

Sealed with 10mm 15mm construction on all sides.

The anointing is strictly sealed, and there is no cultivation.

2).The root of the stove in the tube is added to the casing and tube according to the actual situation.

The seam is left 3 5mm, and the upper seam is sealed with a building.

Paste tightly. 3).The casing is not less than above the ground.

20mm.4).The height of the casing root is within 30 mm.

The ground is not less than 5mm

5).Other practices are the same as floor drains.

4.Squatting toilet:

1).The waterproof layer below the riser interface is sealed with 10mm 15mm building sealing paste, and the upper waterproof layer is at the top and sealed around it.

2).The interface between the toilet and the riser is sealed with construction sealing paste or putty.

It is recommended that you choose a waterproof company with quality assurance and a good reputation, and it is recommended that Guoerjia waterproof materials are recommended.

When a family bathroom is being renovated in a branch, waterproofing is very important. Otherwise, if there is a leak, it will affect the residents upstairs and downstairs, so pay attention to waterproofing. SoBathroom waterproofing pointsWhat are they?

First fill the bathroom, fill in the corresponding base layer after landfilling, and then brush the waterproof paint once, pay attention to the ground must be kept clean and dry before construction, this waterproof paint must be filled to ensure that there is no omission, and the combination with the base must be firm. The height of the coating should be consistent and the thickness should meet the specified standards. The process of coating waterproofing materials:

Before painting, the base layer is cleaned, the original decorative materials are removed, and the floating soil and cement are cleaned. When waterproofing the floor, brush the waterproof coating and glass cloth to the wall 20 to 30 cm above the ground to prevent leakage at the joints between the wall and the ground. For the shower area, apply a water-repellent coating to the wall about a meter long.

In order to prevent subsequent construction from causing damage to the waterproof layer, it is usually necessary to wait until the paint is dried for the first time before entering the second coating application, but the specific time is mainly determined according to the coating. A protective layer should be applied to the surface of the water-repellent coating. The protective layer should be completely covered with a waterproof layer and ensure that it is firmly bonded to the base layer, with no cracks, no round bubbles, and no falling off.

This is followed by the second coat of waterproof coatings. It must be separated from the first waterproofing coating, and if the interval between waterproofing coatings is too short, the waterproofing effect will be greatly reduced. The protective layer of application isBathroom waterproofing pointsneeds to be taken very seriously.

The closed water test should be maintained for at least 24 hours, and the water at the high point of the ground should not be less than 2 cm, and it is qualified after observing that there is no leakage. If there is a leak, you need to redo it and never ignore it. After the completion of the water cut-off test, the waterproofing works are still not completed.

At this time, a protective layer of cement should be made on the waterproof coating, and the ground should be leveled, and it should have a certain slope, which is good for water discharge. ​

Toilet Waterproofing Specification – Process Requirements.

1. The vibration of the bathroom floor must be dense, wiped with the beating, compacted and wiped, and formed a self-waterproof layer.

2. The gaps around the pipe holes and casing holes of all floor slabs are poured with bean stone concrete mixed with expansion agent, and the expansion concrete is poured by hanging mold if the holes are large. After all the treatment is completed, the irrigation test is carried out, and there is no leakage for 24 hours, and the next process - cement mortar screed can be carried out.

3. After the completion of the base leveling layer, it should be solid and flat, clean and free of hollow drum loosening, obvious cracks, hemp surface, sand and other phenomena, otherwise cement glue putty should be used to repair it to make it smooth. All corners are made into a radius of 10mm uniform smooth rounded, all pipe fittings, floor drains or drains and other parts must be in place correctly, installed firmly, there must be no loosening, the end is smooth, and with caulking materials for embedding and filling. There is no protruding sharp object in the base layer, and the moisture content meets the requirements.

4. When the surface of the base layer is kept wet, the first layer of waterproof layer can be painted, and the special brush for cement workers should be used for brushing, and the thickness is.

When the first layer of waterproofing is dry, apply the second layer of waterproofing, and when the weather is higher and hotter, spray a layer of fog water on the surface of the first layer of waterproof layer to moisten.

Unless the weather is extremely hot and dry, the elastic water barrier generally does not require special curing treatment. At room temperature, you only need to spray water on the surface of the coating three times on the first day.

5. After the construction of the waterproof layer is completed, the irrigation test should be carried out, and the water storage depth should be 10cm higher than the waterproof layer, and the construction of the protective layer can only be carried out after 24 hours to check that there is no leakage.

For the phenomenon that the bathroom is prone to water leakage, when making a waterproof layer, it is necessary to check it layer by layer. After the construction of the waterproof protective layer is completed, it is necessary to do another irrigation experiment to ensure that there is no leakage in the bathroom.

Toilet waterproofing specification - special node treatment of toilet waterproofing project.

To do the waterproof mortar layer at the foot of the hollow masonry wall and the waterproof around the pipe mouth and drainage outlet, polyethylene elastic waterproof coating should be added, and the depth of the glue extension and the downspout is greater than 50mm, and the waterproof coating should be applied to the waterproof layer for many times, and the flashing height is more than 150mm.

The bathroom is a relatively stable part of the house structure, but the area is relatively narrow, there are many pipes, and the most permeable part is concentrated in the yin and yang corners, pipes, sanitary ware, floor drain periphery and other places, so it is recommended to use kitchen and bathroom waterproof slurry when doing waterproofing, first use its unique quick-setting repair mortar to repair and strengthen the yin and yang corners, sanitary ware, floor drain periphery, etc., and then use the prepared permanent waterproof slurry to do waterproofing as a whole, so that the first local reinforcement and then the overall waterproofing, The waterproof effect of the special material is definitely better than the general material.

Standard construction is the guarantee of good waterproof effect, so it is recommended to carry out standard construction according to the product description. Here are the standard construction methods for your reference:

1. Chisel the root of the pipe, the periphery of the floor drain and other parts that have cracks and need to be repaired into a "V" shape, clean them, and sprinkle them with water to moisten;

2. Add water (water-cement weight ratio 1:2 3) to the [permeable crystalline repair mortar] and mix it evenly, and carry out repair construction before the initial setting (within 5 minutes), and the root of the pipe, the perimeter of the floor drain, the yin and yang corners, and the root of the wall should be made into r angles;

3. After the final setting of the repair mortar, stir the powder and liquid material of [durable waterproof slurry] evenly, let it stand for 3 minutes, stir it again and evenly brush it on the base surface, and it should be cross-brushed twice, and only after the first surface is dry can the second construction be carried out;

4. Anti-stampede after completion, closed water inspection can be carried out after 48 hours.

Use a waterproofing agent for rigid waterproofing.

Reason: Bathroom leakage is generally leakage from the gap between the floor tiles, as long as the surface layer is rigid and waterproof, it is OK to take a bath without leakage; For example, if the water pipe is leaking, the waterproofing you make on the bottom floor so that the water leaks from the downstairs will result in slowly soaking all the floors of your house, which is much greater than the cost of repairing the bathroom downstairs! Because if you are not waterproof, the downstairs will find that the leakage will be more timely, and the loss will be minimized, in addition to the bathroom made of wooden sheds, any other shed board will not have a loss, and the other is not afraid of water.

Generally, it is a plastic pipe, anti-aging, and the node has a special node pipe to buy, with waterproof water pipe glue.

The waterproofness of the bathroom is an important indicator to determine whether the bathroom is good or not. To meet waterproofing standards, the construction process is very important. The following will show you how a bathroom is waterproof and impermeable.

First, the construction process of special waterproofing for toilets:

1. Waterproof for toilets. Start by brushing with a water-repellent coating. Before construction, the site must be cleaned, moisture is not allowed, it should be covered with waterproof casing, there should be no leakage, it is not obviously connected with the matrix layer, no cracks, no bubbles.

The brush height is constant and the thickness is required to meet the requirements of the product.

2. The special waterproof for the bathroom is brushed with a waterproof coating again. The second paint must be separated, depending on the paint. If the interval is too short, the waterproof effect will be greatly reduced.

3. Apply a protective layer. If you are afraid of damaging the waterproofing layer during construction, you should apply a protective layer to the surface of the waterproofing coating. The protective layer must cover the waterproof layer and there is no leakage. It adheres firmly to the base layer, has no cracks, bubbles and does not fall off.

4. Waterproof closed. In the closed water test, the level should not be 2 cm below the ground level and should be maintained for at least one day to see if there is any water leakage. If there is a leak, you need to redo it. Don't ignore it.

Second, the waterproof details of the special waterproof bathroom are:

1. Before the special waterproof construction of the bathroom, the surface should be clean and dust-free. Otherwise, it will affect the adhesion of the coating and impurities. This is an important step in the foundation treatment of the wall. At the same time, it is essential to ensure that the surface is sturdy and free of peeling, dust or drums.

2. When the dust on the floor of the toilet special waterproof is cleaned, and the layer of condensed and loose foundation must be removed, the remaining hollow part after conversion should be treated in a special way and the yin and yang should be dyed into an angular arc (or V-shaped). You must first level the floor with cement mortar and then waterproof. This prevents the waterproof coating from escaping due to uneven thickness.

3. Each corner of the bathroom is painted in situ for waterproofing, because the bathroom is a place to treat water, all kinds of pipes, we must pay attention to whether the connection between the pipe and the ground is not. Leaks in the general walls of the bathroom are due to the fact that an impermeable material is not evenly applied between the pipes and the walls.

4.The waterproof coating on the walls should also be applied higher, otherwise the water will penetrate into the walls and it will be very easy to damage the walls. If the surface of the bathroom is a lightweight wall, the entire wall should be coated with waterproof paint.
