The damp wall on the floor of the house feels that waterproofing can solve the problem. It is actually wrong. Ground moisture protection is actually a hidden project. If you do not do a good job in decoration, you will often be unable to make up afterwards, or you will pay a heavy price. The following small series for everyone to introduce the ground moisture-proof practices and home improvement moisture-proof attention to four aspects of the relevant content.
Ground moisture practices
1. Remove dirt, mortar, and other debris from the base surface, re-erect the bricks that have been touched, fully wet and wet, and allow the surface to dry slightly.
2. Apply moisture barrier on both sides to ensure 20mm thickness. It is not allowed to use the thickness of the moisture barrier to adjust the deviation of the base elevation.
3, the surface of the mortar is rubbed with a wooden trowel, and when it starts to dry, it can be wiped (2 to 3 times). When applying pressure, sprinkle a little dry cement on the surface or brush a warm cement paste to further plug the mortar capillary passage. The construction of the moisture-proof layer shall be as far as possible without leaving the construction joints, and shall be done once at a time. If it is necessary to retain them, it shall be left at the entrance.
4. After the damp-proof mortar has been wiped, it can be watered and cured the next day. A 20mm thick 30mm thick layer of sand can be placed over the moisture barrier to cover a layer of brick and watered once a day to maintain a good moisture conservation environment. At least 3 days of conservation before you can build a wall on it.
5. For the construction of 60mm thick concrete ring beams, attention should be paid to the concrete gravel gradation and gravel clay content. The girder surface should be reinforced with trowel pressure, and can also be removed by dry cement calendering. The curing method should be the same as that of cement mortar. Floor.
6. Do not mix salt in mortar and concrete in moisture-proof layer. Under no-insulation condition, winter construction should not be carried out. The moisture barrier should be checked and accepted according to the concealed project.
Home improvement moisture precautions four aspects
1, doors and windows is very important for moisture
Many people are concerned about the moisture protection of bathrooms and floors, but they ignore the moisture protection of doors and windows. During the renovation process, moisture protection of doors and windows is also necessary.
In order to avoid the deformation of the facade due to high humidity, the general family will not choose to install wooden doors to the bathroom, but it is rarely thought that the door covers, wooden washbasins, wooden washbasins in fact need to be treated with moisture. Most wooden articles in wet bathrooms have been treated with moisture-proof treatment by manufacturers, and the surface has been coated with a protective layer of paint. It is unlikely that deformation, cracking, and warpage will occur in the autumn when it is particularly dry. However, the decoration company's own furniture And door cover is best lined with a layer of moisture-proof paper.
For such a situation, the owner can maintain the ventilation of the bathroom in daily life, do not mix water in the adhesive, prevent wood products from absorbing excessive moisture and quality problems.
2, normally open exhaust fan
Just now we mentioned that the wooden door of the bathroom was damp-proof. Then the experts had to make a knowledge supplement to the owner for the bathroom wall that was most easily damaged by moisture. In this regard, many owners think that it is caused by the leaking of bathroom pipes. In fact, the water on the bathroom wall permeates into the wall.
The owner should first open the exhaust fan or window ventilation to discharge the moisture; second is to do a waterproof layer on the back wall of the cabinet in the bedroom. During the decoration process, wardrobes, cupboards and other furniture must be kept away from the walls to prevent the moisture in the bathroom from penetrating the bedroom through the walls.
3, water pipe installation is more important
In addition to the above, we must also pay attention to the water pipe problem. More formal decoration company is not the most important thing is the surface design and decoration, but the installation of hydropower pipelines, which in turn is more important. Because wires can generally be mounted directly to the end of a line, as long as the construction is in accordance with regulations, line problems are less likely to occur. The pipe used today is only 3 meters long. Pipelines over 3 meters in length must have two pipes connected together, and there may be leakage problems at the ports.
What is even more troublesome is that this type of leaking pipe problem cannot be discovered in the short term. Once discovered, it may cause a lot of inconvenience to the owner's life. Even neighbors downstairs may suffer. The industry mainly chooses a decoration company with a good reputation for construction. When signing the contract, it must be clear that the warranty period for the hydropower project should be slightly longer, generally about 5 years. In this way, the owner has no worries. Also try to pass the water line from the top of the room, not to the ground, because the cost of renovating the bathroom floor is higher than the top of the renovation.
4, up and down the floor as much as possible
Up and down the floor as far as possible ventilation, and now the new house generally has a basement floor, the so-called first floor is actually the 1.5th floor or the 2nd floor, the ground is unlikely to appear wet. What's more, nowadays flooring is mostly lacquered wood, and wood and air are effectively separated by paint. In general, moisture does not affect the moisture content of wood. The first consideration for tenants is how to use the ridge to make the floor dry for a long time. The decoration user mixes the waterproofing agent in the cement mortar to make a firm waterproof layer, after the ridge is laid, add a layer of moisture-proof pad between the ridge and the floor.
What if we don't have a wet house in the basement? Only from the grass-roots ground began to transform, experts suggest that the keel of the floor height, while leaving a certain gap, so that the ground across the floor can also maintain air circulation with the outside world. Laying the floor should not be too strict, between the floor and the wall should also set aside about 1 cm of floor expansion joints, giving the wood thermal expansion and contraction to leave room.
For the work of preventing moisture, we must consider at the beginning of decoration design that choosing a decoration company with a reputation can solve these problems to the maximum extent. In addition, during the decoration, we must also negotiate the details of the maintenance in the later period. In this way, there are still some solutions to follow-up if there is moisture in the house.
Xiao Bian concludes : The relevant contents of the ground moisture prevention practice will be introduced to this and I hope to help you. More exciting information is on this site.
