When to do bathroom waterproofing, do it before laying floor heat or after laying floor heat

Do it after laying the floor heat, because after the floor heat is laid, the water pipes should be sealed with cement, of course, including the water pipes that seal the bathroom floor.

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 of the destruction 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 waterproof treatment, then a layer of glass silk cloth should be laid, a layer of modified asphalt should be painted repeatedly, and then a layer of glass silk cloth should be laid, and then 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.

5. Closed water test. After the waterproof 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 one day, 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.

Generally, the waterproofing of the bathroom is done after the floor heat is paved, and the water pipe should be sealed with cement when the floor heat is paved, including the water pipe of the bathroom. When collecting the house, you need to do the water test of the kitchen and bathroom, and the waterproof test can be divided into two times or three times when the bathroom is renovated, the first time the caisson floor is cleaned up and done once, and then after air drying, the second flooding slope is done, and then the third time is done after drying, and then filled with ceramsite after air drying, and then cement sand leveling, and then the bricks are paved.

1. Before carrying out the floor heating construction of the bathroom, it is necessary to first complete the waterproof construction project of the ground and wall of the bathroom.

Second, because the bathroom area is relatively small, and there are far more pipes buried underground than other rooms, the process of installing floor heating in the bathroom is more complicated than other rooms. It is recommended that families who need to install floor heating in the bathroom should pay attention to the following aspects:

1. The bathroom is the place where the household uses the most water, so the most important thing to pay attention to when the bathroom is paved with floor heating, generally speaking, the professional floor heating installation company will do two waterproofing when laying the floor heating pipe in the bathroom, once is after all the floor heating is installed, in order to ensure the temperature of the floor heating.

2. There will be more things on the bathroom floor, such as toilets, bathtubs, basins and various sanitary appliances, which make it difficult to dissipate the temperature from the bottom up to the whole room, which affects the heat supply of the bathroom floor heating, therefore, when the bathroom is paved with floor heating, it is generally designed according to 20 -24.

3. Bathroom floor heating, especially when used in winter, because of the need for higher heat load and heat supply, it is best to choose high-power products when choosing floor heating, which can avoid the problem of insufficient heating affecting the bathroom temperature when high heat is needed.

Hydropower. Water pressing, waterproofing, floor heating, pasting floor tiles. Wall tiles, carpentry, painting homes, lighting decorations, opening windows to disperse odors, moving.

It's a bit of a waste to do underfloor heating in the bathroom.

If there are several types of heating in the whole building, the house, including the bathroom, should be very warm. During the coldest period, it would be nice to put on an electric heater.

I did waterproof + then did floor heating, if there is water leakage in the future use process, it will be a big trouble.

In accordance with the provisions of the technical regulations:

The bathroom needs to be waterproofed with two layers, before and after the shop.

I just finished installing my home, and the waterproofing has to be done behind the floor heat.

The waterproof layer can be done before laying bricks to avoid damage in other processes.
