Which is the best waterproof coating for the bathroom? What do I need to pay attention to when water

Regarding the selection and construction of waterproof materials for toilets, there are several suggestions:

1.The first thing to pay attention to when doing waterproofing in the bathroom is the choice of waterproof materials, and it is recommended that you can directly use the waterproof slurry in the kitchen and bathroom, which is specially developed for the yin and yang angles that are easy to seep into the kitchen and bathroom, wear pipes, sanitary ware, floor drain peripherals, 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.

The more cost-effective are waterproof, and the price of Degao Yuhong is high. K11 waterproof coating, JS waterproof coating.

Materials, Kaixin waterproof coatings, etc. can be brushed bathroom waterproof. As long as the construction method is used correctly, the base surface must be treated and smoothed to ensure the waterproof effect.

You can use polyurethane, Shenglong brand, and Onuokang.

The waterproof knowledge of the kitchen and bathroom is basically as follows:

1. What kind of waterproof material is used? It is recommended that waterproof materials use polymer cement-based waterproof coating slurry, that is, the name on the market is: general-purpose, flexible, K11, JS, GS waterproof coating slurry, this kind of product is water-based coating, non-toxic, harmless and pollution-free, simple and fast construction, and cement substrate bonding tightly, long service life, strong waterproof effect, moderate price and other significant characteristics.

Choose brands with good quality and good reputation, such as: Leibangshi, Degao, etc.

2. How to construct? Deal with the base surface (substrate) of the waterproof position. The base surface is treated into a firm, flat and clean surface, free of dust, greasy, wax and other debris substances; If there are pores, cracks and unequal defects on the base surface, it must be repaired and smoothed with cement mortar in advance, plastic strips are recommended to be pasted on the expansion joints, a layer of non-woven fabric must be added to the node, and the nozzle filling is recommended to use Leibangshi plugging king or nozzle grout; The corners of the wall should be plastered into an arc shape (or V-shaped); Make sure the base surface is sufficiently wet, but there is no open water; Pay attention to the waterproofing to be in place.

Use a brush or roller brush to apply directly to the base surface, and the strength is used evenly, and the brush should not be missed; Generally, it needs to be brushed twice (according to the requirements of use), and the thickness of each brush should not exceed 1mm; After the previous one is slightly dry, the next one is brushed (just non-sticky, generally at an interval of 1-2 hours), and the front and rear vertical cross brushing, the total thickness of the brush is generally 1-2mm; If the coating has already cured, moisten it with water first when applying another layer. Special attention should be paid to the corner part of the wall to be treated into an arc type and then painted, and the painting can not be too thick (the total thickness does not exceed 2); The pipe should be sleeved with a casing, and the holes of the casing and the wall should be filled with a plugging king, and the waterproof material should be brushed to the height of the casing 10 and not too thick;

3. What are the special precautions? Pay attention to the position and height of the waterproof applied. Ground; Generally, the wall is repainted and brushed 30 high; Paint the wall around the shower area 180 high or to the top of the wall; There is a bathtub where the upper brush is 30 higher than the bathtub.

Do a good water test. After the waterproof coating is painted to form a waterproof layer (about 24 hours later), the water storage is 20 high, and after 24 to 48 hours, see if the water is significantly reduced or go downstairs to see if there are wet water spots on the roof, and if not, it means that the waterproof construction is successful.

1.Demolition of walls and floors.

It is very important to remove the wall and floor of the bathroom, which directly affects whether the waterproofing of the bathroom can be done at one time. Demolition requirements: the wall must be removed to the bottom layer; Ground culling to floor level; The wall, the ground, and the connection between the wall and the ground shall not leave an acute angle of concrete; There shall be no rebar heads; There must be no unevenness.

2.Do the protective layer.

The purpose of making a protective layer on the top and bottom of the waterproof layer is to protect the waterproof layer from being damaged by the sharp clucking below the waterproof layer, and the heavy objects or edges and corners above.

3.Waterproof coatings.

The waterproof coating shall be a qualified product that meets the requirements of national and local regulations. For example, Viske, Yuhong, JCDecaux.

4.Brush with waterproof paint.

Generally, waterproof paint is basically used for home decoration, and the waterproof paint must be brushed with a brush, not rolled with a roller, and a brush should be brushed next to a brush, and there must be no omission; When brushing the next time, wait for the last time to cool and dry before brushing; And to alternate vertical and horizontal brushing, when brushing the wall, we must pay attention to the waterproof coating at the junction between the root of the wall and the ground, and be sure to brush in place; The waterproof coating on the ground should be connected with the waterproof coating on the wall to form a basin pattern.

5.Closed water test.

After the protective layer on the waterproof coating dries, it is necessary to carefully do the closed water test in accordance with the relevant regulations. Don't be perfunctory.

1. First of all, the flowing surface, that is, the toilet and kitchen of the house, because these two parts have flowing water or often wet all year round, waterproofing is naturally extremely important, and must not be taken lightly.

2. The second is the exposed surface, such as balconies, terraces, rooftops, etc., because they are exposed outdoors and have been eroded by rain and snow for a long time, they must also be effectively waterproofed.

3. The moisture-proof surface is again, which usually refers to the ground and wall of the house. When the house is decorated, the wall is generally not dry, contains a certain amount of moisture, and there are often new walls or new cement mortar, if not waterproof, the water will evaporate, causing discoloration, shelling and mildew and other problems. In particular, once the wood parts such as wooden floors, wooden wall lines and door frames seep into the water, they will be discolored, moldy, and insects due to moisture, until they are unusable, and they are waterproof and plugged.

4. Another thing that is easy to ignore but must be reminded is the waterproofing of the backwater, which is mainly for residents close to the exterior wall units of the building. If the builder's exterior wall waterproofing treatment is not in place, due to long-term rainwater washing, moisture will gradually seep into the interior wall of the room, if there is no waterproof barrier, interior wall wallpaper, paint and other decorative materials will suffer.

The general bathroom leakage water is the details of the building problems, the most prone to problems in three places, we should pay attention to the three places are floor drains, wall corners, pipe roots, these three places due to more interfaces, easy to appear gaps, so easy to leak water. In addition, if the connection between the bathtub drain and the sewer pipe is not tight, it will be easy to create gaps and leakage. Therefore, we should choose a coating that is most suitable for bathroom decoration, and we should choose Langkaiqi flexible-acrylic modified waterproof coating for waterproof coating.

Because this material can tightly wrap the pipe and the ground, penetrate into the gaps, and will not shrink after drying, it is more suitable for small areas of houses with many pipes and gaps such as bathrooms than rigid materials such as waterproof cement. Therefore, customers should choose Longkeqi brand coatings when buying this kind of paint.

After the waterproofing construction is completed, all the sewers in the bathroom should be blocked, and a "low wall" should be built at the door of the bathroom for water injection test, and the water injection height should be about 500px. After 24 hours, if there is no leakage on the walls and floors around the bathroom, it means that the waterproof quality of the bathroom is very good. On the contrary, it is necessary to find out the leakage point and carry out repairs.

At the same time, the wall should also be waterproof. In order to achieve a better waterproof effect, the wall of the general bathroom should also be waterproofed about 750px high to prevent water from penetrating the wall. The wall adjacent to the bathtub should also be waterproofed at a higher height than the top edge of the bathtub.

In this way, nothing is lost.

Bathroom waterproofing, if you want to use waterproof coating, then it is recommended to use K11 waterproof slurry, K11 waterproof slurry is a two-component polymer cement-based waterproof material, after mixing the liquid and powder in proportion, use a stiff brush to evenly and densely brush in the place that needs to be waterproofed, you can form a complete waterproof layer, waterproof effect is significant. But remember to make a protective layer of mortar waterproofing agent after brushing the waterproof slurry, which is stronger and more resistant to punctures.

As for the precautions for construction:

1.The first thing you need to pay attention to in waterproofing is the choice of waterproof materials, different home decoration parts need to choose different waterproof materials, some are suitable for rigid waterproofing, such as kitchen and bathroom; Some require a rigid and flexible combination, such as a roof or balcony.

2.The construction of waterproofing should be carried out according to the standard construction according to the instructions, 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 and sprinkled with water.

5.Remember to do a closed water test after the waterproofing is completed.
