How to use the old stubborn kitchen and bathroom waterproof slurry?

Step 1: Check and process the base surface.

Before doing waterproofing, all construction base surfaces should be inspected and cleaned, and the hollow drum should be chiseled; The cracked parts around the pipe and floor drain must be chiseled into a "V" groove; After the overall base surface is cleaned, sprinkle water to moisten, but there should be no stagnant water.

Step 2: Repair the leak-prone areas.

According to statistics, 95% of the leakage between the kitchen and bathroom occurs in the pipes, floor drain perimeter and wall corners, in order to completely eliminate the hidden danger of leakage, it is necessary to repair and enhance the kitchen and bathroom with a self-healing function of the kitchen and bathroom special repair mortar.

Use the prepared repair mortar to fill the grooves and potholes around the pipes and floor drains, and the corners of the wall should be made into "R" corners, which can self-heal the microcracks caused by structural changes, so that these permeable parts do not leak. After the repair is completed, it is ready to do the overall waterproofing.

Step 3: Paint the waterproof slurry as a whole.

After the repair mortar is solidified, it is painted with anti-aging and corrosion-resistant waterproof special waterproof slurry for kitchen and bathroom. The powder and liquid must be mixed in standard proportions, stirred evenly until there is no dough, let stand for 3 5 minutes, and stir again before use.

The painting construction should be carried out according to the steps of first the wall and then the ground, first far and then near. The height of the wall painting in the bathroom must reach more than one meter or full height, and if it is a light wall, it must be painted at full height to avoid water vapor from penetrating into the wall through the tiles. The height of the kitchen wall should not be less than 30 cm, and the water parts such as the vegetable sink should be 50 cm higher than the water outlet.

The waterproof slurry should be brushed twice, first horizontally, and then vertically after the surface of the waterproof layer is dry, so as to avoid missing brushing. In particular, pipes, floor drains, and wall corners should be taken seriously. In addition, the door frame and threshold stone should not be ignored, and they must be brushed to prevent moisture return.

Step 4: Protection.

After the construction is completed, it is strictly forbidden for the waterproof layer to be trampled on or punctured.

Step 5: Closed water test.

After 48 hours, the closed water test can be carried out. The closed water inspection shall not be less than 24 hours, and the follow-up construction such as tiling can be carried out after passing the inspection.

Precautions: 1. The temperature of the construction environment should be 5 35;

2. [Permeable crystalline repair mortar] will generate a little heat during the construction process, and the waterproof slurry construction needs to be cooled down;

3. The stirred waterproof slurry should be used up within 1 hour;

4. It is strictly forbidden to mix this product with other preparations.

The old stubborn kitchen and bathroom waterproof is the country's first special waterproof material for kitchen and bathroom. It can eliminate the weak points in the kitchen and bathroom due to small space, many pipes, long-term immersion in water, etc., completely eliminate the hidden danger of water leakage, and greatly extend the waterproof life. And the product has long been.

It has passed the inspection of relevant departments and applied for a number of national patents, which is the best choice for waterproofing in the kitchen and bathroom. As for the specific **, you can go to the building materials market to ask.

Hope it solves your problem.

The old stubborn kitchen and bathroom waterproof slurry is a kind of building waterproof material, which is specially used for waterproof and moisture-proof treatment of kitchens and bathrooms before decoration. It is composed of a penetrating crystalline repair mortar and a durable waterproofing slurry. It has the characteristics of anti-aging, anti-erosion of daily chemicals, and adaptation to the deformation of the structural base.

The old stubborn kitchen and bathroom waterproof slurry is packaged in a combination. The permeable crystalline repair mortar has self-healing properties, which can eliminate the hidden danger of leakage between kitchens and bathrooms; The durable waterproof slurry has the characteristics of anti-aging, resistant to daily chemical erosion, and adapting to the deformation of the structural substrate.

The specific construction method of kitchen and bathroom waterproof slurry:

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 to the [permeable crystalline repair mortar] (water-cement weight ratio 1:2 3) and mix it evenly, and carry out the repair and filial piety repair construction before the initial setting (within 5 minutes), and make R angles at the root of the pipe, the periphery of the floor drain, the yin and yang corners, and the root of the wall;

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.

Hope it can help you!

Kitchen waterproofing generally uses JS waterproof coating, not too much, simple to use ordinary waterproof coating

In fact, there are many precautions for the construction of kitchen and bathroom waterproof slurry, and some of the more common ones are listed below

Before construction, the base surface needs to be cleaned without oil, dust, etc., and then sprinkled with water to moisten it, but there should be no stagnant water.

The ratio of the quick-setting repair mortar is three parts of mortar, one part of water, and the prepared repair mortar should be used within 5 minutes.

It is recommended to control the temperature between 5 and 35 degrees Celsius during construction.

The permeable crystalline repair mortar will generate a little heat during the construction process, and it needs to be cooled before the waterproofing slurry is constructed.

The stirred waterproofing slurry also needs to be used within 1 hour.

Do not mix powder, liquid, etc. of this product with other preparations to ensure a good waterproof effect.
