What is the difference between bathroom waterproofing and kitchen waterproofing, and what do you nee

Construction points: 1. Deal with the base surface of the ground and wall in the waterproof position of the bathroom. 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 is recommended to use 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;

2. Pay attention to the waterproof construction in place. Use a dusty hole brush or a roller brush to directly brush on 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 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 pipes should be covered with casing, the holes of the casing and the wall should be filled with plugging kings, and the waterproof material should be brushed to the height of the casing 10 and should not be too thick;

3. Pay attention to the position and height of waterproof painting. 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.

4. 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. (This is the only standard for testing the waterproof performance of the waterproof layer!) ）

Bathroom waterproofing needs to pay attention to the waterproof height of the place where there is shower liquid is not less than 2m, guess the waterproof position of the cherry blossom hand basin is higher than the hand basin, the height of other positions does not matter, the height of the return is higher than the above;

The kitchen is a sink location that is waterproof higher than the sink, and other locations don't matter.

The material is the same, but the bathroom is waterproof, and the kitchen is fine.

First of all, it is best to choose a well-known waterproof material produced by a regular manufacturer when buying waterproof materials, so that the waterproof layer and waterproof years can be guaranteed. Three points for materials, seven points for construction.

Attention needs to be paid to the waterproofing of the kitchen and bathroom:

1. The waterproof layer of the kitchen, the ground is all waterproof, the wall is more than 30 cm high, and the waterproof of the water is not lower than the water range.

2. The waterproofing of the bathroom is done twice, and once before the backfill (after the pipeline is modified), the main purpose is to prevent the pipeline from bursting and causing a large amount of water seepage. The waterproofing after backfilling is carried out after the water and electricity is completed (before tiling), the main purpose is to prevent the water from leaking down, and also to prevent moisture from eroding the wall and causing mold.

The waterproof height should be at least one meter high, and it is recommended to do the full height if possible, and if it is close to the bedroom, it is recommended to do the full height by the wall of the bedroom.
