With the advancement of modern times and society, many people may think that the concrete floor is not beautiful, and the colors and the feet are relatively cold. In fact, the finished concrete floor is self-leveling, and it can be coated again to produce various effects. It is very beautiful. Here we introduce: the cement floor construction process and how to do the cement floor wet . First, the construction process of the cement floor 1.20 Thickness 1:2 Cement Mortar Compacted Wiping Cement Mortar Ground Quota 2.

This happens mostly in the rainy season where there is plenty of rain, high temperatures, and high humidity. Once the climate is clear and dry, the phenomenon of flooding can be eliminated; second, the water in the ground soil under the ground cushion rises through the action of the capillary, and the upward penetration of the gaseous water causes the ground material to wet, and worsen the humidity of the entire room. This situation often occurs year-round and is difficult to handle. There is also poor drainage around the outdoors, and poor ventilation of the room can cause large areas of dampness. However, when building materials with poor compaction are used as indoor flooring, they will increase capillary action, which will make the phenomenon of ground dampness more serious. Third, the inspection and treatment of wet ground 1. Check: First check the ground for cracks. Cracks are the main channel for upward penetration of groundwater. Concrete mortar or concrete poured on the ground, generally cracks with a width of 0.05 mm or more are visible cracks. Regular cracks usually occur in the longitudinal or transverse direction of the room and are formed by shrinkage and cracking of the material. Then check whether there is empty drum on the ground. Use a wooden stick to tap the ground and tap it gently. If the sound of the tap sounds, there will be empty drums. 2. Cracks: empty drum treatment. For regular cracks, a 'V'-shaped joint should be cut and the inside of the joint cleaned and sealed with bitumen ointment. If you can use the flame to bake, make the cracks fully dry, the effect is better. Hairline cracks are generally closed for large areas. For areas where empty drums are available, the surface layer should be knocked out, the cushion be cut, and a grout brushed on the cushion. The same material as the surface layer should be used to repair the leveling. 3. Moisture-proof treatment: after the local treatment of cracks and empty drums, the surface layer should be fully dampened and sealed. The principle of treatment is to block the capillary water seepage channel in cement mortar or concrete. Can generally be painted waterproof coating or waterproof agent method. Before brushing, first cut the surface of the hair, clean, brush two waterproof paint. Apply force on the first brush to get it deep into the pores. After the first coat is dried (usually about 24 hours), it is painted again for the second time, so that the overall waterproof coating is formed. At the corners of the floor and wall, the paint should be brushed to the height of the wall skirting board. After the original ground is damp-proofed, a new surface layer will be made. The selection of new surface materials should consider the use of high-strength, wear-resistant, have a certain moisture-proof ability, easy to clean, practical and beautiful surface materials, can also use cement mortar surface layer. As for the air humidity, in addition to the special equipment needed to control the humidity, the general building should not open the window facing the wind, less open the door facing the wind, reduce the humid air into the room.
