If it is already built, it can only be solved by brushing the waterproof coating and ventilation. If it is wet before the house is built, linoleum should be placed at the base to prevent capillary action. After the outer wall is painted, a waterproof coating is applied to find the moisture. The source directly works best. There are many people do not understand the method of wall foot damp proof , the following Xiao Bian simply describes the next layer of foot damp proof layer practice . What is the practice of the moisture barrier on the wall? It is better to waterproof the exterior wall so that rain cannot seep into the wall. The specific approach is: The basic method of moisture-proof layer: Put linoleum at the base, combine the parts with brushed asphalt or waterproof water coating to prevent the capillary action, the ground is damp and the exterior wall painted with waterproof coating. The foot of the damp layer practice process: 1. First apply a layer of waterproof paint on the exterior wall, including the roof. 2. Add 10% moisture-repellent agent to the mortar layer below 10cm. After such a process, stick the external wall tiles or other decorative materials on the line. If it is difficult to waterproof the outer wall, you can also waterproof the inner wall, shovel out the original wall surface, expose the cement wall surface, clean the wall surface, and ensure the construction surface is dry, and then brush the waterproof coating. Good waterproof coatings, such as: Oriental Yuhong or Golden Shield two-component waterproof coating can be, do not brush too thick each time, in 3 or 4 times, there is a layer of waterproof membrane formed, until the coating is completely dry, Then scrape waterproof putty, followed by painting followed by latex paint, so that the external wall of water can not seep into the room. There are several approaches to the ground layer (1) Waterproof mortar dampproof layer Apply a layer of 20mm or 30mm thick waterproof mortar made of 1:3 cement mortar mixed with 5% waterproof agent at the position of dampproof layer; you can also use waterproof mortar to build 4-6 tiles. Indoor floor up and down. The use of waterproof mortar as a moisture barrier is more suitable for buildings with seismic protection requirements. (2) The linoleum moisture-proof layer First apply a 20-mm-thick mortar screed on the damp-proof layer, and dry the linoleum layer or stick a felt and oil with hot asphalt. The linoleum width is the same as the wall thickness and is laid along the length with a lap length of ≥ lOOmm. The linoleum moisture barrier layer has certain toughness, extensibility, and good moisture resistance performance, but is prone to ageing failure, and at the same time, because the felt layer reduces the adhesion between the upper and lower brick masonry, it weakens the seismic resistance of the brick wall. (3) The fine stone concrete moisture-proof layer is made of concrete with good compactness, certain waterproof performance, and can be combined with masonry as a whole, and it is commonly used with 60mm thick reinforcing fine stone concrete moisture-proof zone. This practice applies to buildings with high overall stiffness requirements. (4) Vertical vapour-proof layer The vertical wall surface of the indoor floor of the room where there is a level difference, in addition to the upper and lower horizontal vapour barriers, the vertical wall surface (on the side of the filling site) is first plastered with cement mortar. Brush with a cold base oil, and then brush hot asphalt two; you can also use a mortar mixed with waterproofing agent practice, the other side of the wall requirements for the rendering of cement mortar wall plastering. Xiao Bian concludes : The related contents of the practice of the anti-moisture layer of the foot wall are introduced to this and I hope to help you. More exciting information is on this site.
