Selection and use of waterproof canvas

Because there are many waterproof protective materials now, everyone is particularly troubled when choosing, because they cannot find suitable products, and the quality cannot be guaranteed. Let's take a look at the waterproofing steps of using tarps, because if new materials are discovered, but the waterproofing steps are not done well, then even if the important process is ignored, it is easy to have problems. The following are some classifications of waterproof canvas, I hope you can handle these situations with caution. When using tarpaulin, clean the end first, then punch, fill, and grout, the effect will be very good. 1. To clean up the end, first check the ground condition in detail, and at the same time analyze the place where leakage may occur. After determining the location and spacing of the grouting holes, the construction area must be cleaned and surface deposits scraped off to ensure that the entire base is level and clean. 2. Drill holes with a drill. At this time, we will definitely use a tool called a drill, which is to make a hole around the four holes, but at this time, it cannot directly penetrate the structure, or if the hole is large, the dust inside will be automatically cleaned up, slowly Penetrate slowly. In this case, the cleaning step in front of the end will be the same as if it was not done. 3. To fill in the gaps, this step can be cumbersome. First observe the pressure of the main leaking holes to ensure that the structure reaches a certain strength and does not leak. As the pressure and water flow gradually decrease, quickly bury the desiccant in the water needle injected into the grout, ensuring that there is no gap between the drill bit and the grout, and no water leakage. This step may be an incomprehensible part of bathroom waterproofing, but in fact, it is completely mastered after many operations. 4. The steps of grouting and filling the river need to use high pressure grouting, but in the process of high pressure start-up, it must not exceed the range that the structure can bear. If grout flows from two adjacent holes, this pressure must be maintained for at least 3 minutes. At this point, we can put chemical grout into the grout hole. Waterproof canvas classification Waterproof canvas refers to the special canvas processed for waterproof, moisture-proof, moisture-proof and cold-proof, generally refers to the paint series, which is made of fiber fabrics and chemical fillers through dipping, coating, scraping, drying, cooling and other production processes .
