How to decorate the kitchen and bathroom waterproof and leakage proof

The kitchen and bathroom floor bai degree is constructed according to the design requirements, and according to the ground

The leakage direction is appropriately graded, and the slope return is controlled at the slope according to the design requirements.

Answer: The kitchen and bathroom walls are divided into showers, baths and general parts according to the requirements of the drawings, and the waterproof coating (polyurethane) is painted.

The flue and the pipeline through the floor are plugged with C20 fine stone concrete plus micro-expansion agent, the perimeter is chiseled and cleaned first, and then the formwork is supported, and the fine stone concrete is used to plug it, and the slope is appropriately found from the pipe edge to the outside within 200mm around the pipe.

The 300-width area around the floor drain must be waterproof.

Before the waterproofing construction of the kitchen and bathroom floor, the structure should be tested for waterproofing, and if there is leakage, the source should be found and treated. The next process can only be carried out until there is no water seepage.

According to the design requirements, the waterproof coating film is carefully constructed. The kitchen is 300 mm above the base of the wall, and the bathroom on the floor is up to the top.

Just redo the waterproofing alone.

It is recommended to do mortar flexible waterproofing!

Waterproofing is the most basic bathroom decoration, most of the decoration projects are completed by the construction team, although the owners basically do not need to participate in their own participation, but understand some of the bathroom decoration waterproof process, the grasp and acceptance of the decoration project is definitely beneficial.

1. Introduction of waterproof materials. At present, there are two main types of home improvement waterproof materials on the market: modified asphalt waterproof coating + glass silk cloth and polyurethane waterproof coating.

Glass cloth can increase strength and toughness, and the price is moderate, the disadvantage is that the construction is complicated. The polyurethane waterproof coating is a waterproof coating with a polymer coating film, the waterproof effect is very good, and it is a high-grade material at present, so the price is also high.

2. Key points of painting waterproof materials. Before painting, the base layer should be cleaned, the original decorative materials should be removed, the floating soil and cement should be cleaned up, and the surface should be smooth and dry.

When doing ground waterproofing, the waterproof paint and glass cloth should be brushed to the wall 20-30cm from the ground to prevent leakage at the junction between the wall and the ground, and for the shower area, the waterproof paint should be painted to the wall meter or painted all over the wall to prevent the wall from leaking.

3. When painting waterproof materials, a layer of modified asphalt should be brushed on the base layer of waterproofing, then a layer of glass wire cloth should be laid, a layer of modified asphalt should be painted repeatedly, a layer of glass wire cloth should be laid, and finally a layer of modified asphalt should be painted. In total, it is necessary to brush the modified asphalt three times and lay two layers of glass cloth to complete the waterproof treatment.

4. If you use polyurethane waterproof coating, the construction is relatively simple, you don't need to pave the glass silk cloth, and you can directly apply the waterproof coating two or three times. The polyurethane coating itself can form an elastic protective film, which has a certain toughness, and if you want to further improve the waterproof effect, you can also add a layer of glass cloth. The joints between the wall and the floor, as well as the joints between the water and sewer pipes and the ground, are the most problematic areas.

Therefore, special attention should be paid to these places when doing waterproofing works.

5. Closed water test. After the waterproofing project is completed, you can start to carry out the closed water test seal to check the waterproof effect, seal the door and the drain, and then store the water indoors to reach a certain liquid level height, after 24 hours, if the liquid level does not drop significantly, it is qualified.

6. After the closed water test, the waterproof project is not finished, at this time, another layer of cement protective layer should be made on the waterproof coating layer, and the ground should be leveled, and attention should be left with a certain inclination to help drainage. "When the protective layer of cement mortar is dry, you can put floor or wall tiles on it.
