Repair waterproof meaning
The renovation of new houses will inevitably require hydropower reforms, which will certainly damage the waterproof settings of the original developers. In order to strengthen the waterproof setting, protect property safety and avoid neighborhood disputes, new house renovations must be made waterproof.
Waterproofing process
1. The grassroots floor should be cleaned up. The surface of the original wall surface should be solid and there should be no sanding, dust falling or hollowing.
2. Clean up the roots of the upper and lower water pipes and perform plugging treatment.
3. Use 10-15mm wide textured paper to paste the outline according to the height of the wall design and construction.
4, the first time the emulsion paint construction, the order from top to bottom, from inside to outside, not to miss the brush.
5. After drying for 24 hours, apply a second pass of the emulsion to form a complete waterproof layer of the emulsion in two passes.
6. After 24 hours of drying, conduct a water-sealing test for 24 hours. The water discharge height shall not be less than 30mm. No leakage shall be qualified within 24 hours.
7, After the surface cement mortar is pulled, it can be directly applied to the brick.
Patching waterproof precautions
Check the ground
Before waterproof construction, the original rough surface must be strictly inspected to see if empty drums are present. If empty drums are present on the ground, repairs must be removed before proceeding to the next step.
Floor drain
Most of today's new rough housing are equipped with a floor drain with a ball valve. This type of floor drain has a good function of preventing odor leakage. Everyone should try not to replace it during the renovation to avoid odor leakage.
Water experiment
Before waterproof construction, it is best to do a water test. When testing, carefully observe the speed of water leakage from the floor drain. If the water is very quick, and accompanied by buzzing, it indicates that the water is good. Otherwise, it should be dredged and then renovated.
Drainage pipes
When draining a sewer pipe in a bathroom, slot the pipe if necessary. It should be coated with waterproof material in advance, and then put the water pipe. The finished pipe can be filled with anti-leakage cement to ensure no leakage.
Brushing waterproof material
If the back of the bathroom is the wall of the living room or the bedroom, the waterproof material should be painted from the bottom to the top during construction, and the height of the waterproof wall should be more than 1.8m so as to effectively block the invasion of moisture.
Raise the ground
When the floor of the bathroom is elevated, it must not be filled with debris or even construction waste. The correct process involves the use of cement-mixed yellow sand and melon seeds, and the raised concrete is used for elevation treatment.
Waterproof surface dense
Before laying the tiles, the walls and floors should be cleaned and carefully coated with professional waterproof material to ensure that the waterproof surface is dense and that any capillary hole will not be the main culprit in bathroom leakage.
Flooding slope
In order to achieve good waterproof construction, the shower room should also be equipped with a groundwater flooding slope. The standard flooding slope should be greater than two-thousandths of a millimeter. It can ensure that there is no water accumulation, and it can make people feel less inclined when standing. .
Paving tiles
Wall tiles must be fully immersed in water before laying, and the ratio of cement, glue and yellow sand used for tiling needs to be properly configured and wait 20 minutes before use. The tile thus posted is very strong and can prevent the intrusion of water vapor.
an examination
After the tiles have been attached, they should be carefully checked one by one. The walls of the bathroom should not be tiled. Only the tiles of these important parts are affixed to the tiles to make them the first line of defense against water. .
seal
Special attention should also be paid to the heating pipes, downspouts, and sewers. The gap between these places and the tiles is usually an important part of the leakage. The leakproof cement should be used to repair and seal the tiles, and then the tiles are closely attached.
Door bottom waterproof
The bottom of the bathroom door is also an important part of the need for waterproof construction, in order to prevent the internal water and moisture caused by the appearance of mildew in the door cover, construction should be done waterproof and moisture measures.
Tile Sealant
After doing all the waterproof construction, you cannot ignore the tile sealant. Choosing a good sealant product can effectively block the water vapor from entering the interior of the tile to ensure a good waterproof construction effect.
The main preparations for this step are:
1. Some owners will ignore this step. Toilets and kitchens that are often exposed to water will leak as soon as there is a leak in one place. It will form a string of water inside the floor. Leakage to the downstairs will affect the neighborhood and may cause serious problems. Significant property claims and legal disputes. Second, if you make up for waterproofing, the cost is about 3 to 5 times more than before the renovation, and it will cause great inconvenience to your life.
2. The waterproof project is the same as the hydropower project as a hidden project. It is difficult to repair in the future and the cost will increase several times. Therefore, attention should be paid before decoration; choose a good waterproof material and professional team construction. Avoid unnecessary troubles and losses in the future.
3. The majority of owners of the kitchen interior decoration must leave a floor drain to the water pipe to burst burst and triangle valve damage caused by floods and avoid greater losses. Because many decoration companies and homeowners think that the kitchen floor does not always have water to drain and install floor drains, unlike the bathroom floor. Often, the kitchen floor is not equipped with floor drains. Once water pipes and other problems occur, they suffer heavy losses.
