At present, more and more people will use coiled materials in decoration, but when purchasing coiled materials, we should choose more environmentally friendly coiled materials. The waterproof construction of SBS coiled material is also relatively simple, but attention should be paid to the safety during construction. So what is SBS membrane waterproof?

at present, more and more people will use coiled materials in decoration, but when purchasing coiled materials, we should choose more environmentally friendly coiled materials. The waterproof construction of SBS coiled material is also relatively simple, but attention should be paid to the safety during construction. So what is SBS membrane waterproof? What are the waterproof construction processes of SBS coiled material? Let's take a look with Xiaobian

I. what is SBS coiled material waterproof

the tire base of SBS coiled material waterproof is glass fiber reinforced polyester felt, polyester felt and glass fiber felt. Its two sides not only use isolation materials, but also use thermoplastic elastomer as the waterproof coiled material of the modifier of petroleum asphalt. SBS membrane waterproofing is mainly used in railway, industrial and other waterproof projects, which can be said to cover almost all waterproof projects. So far, it is one of the waterproof materials with the best waterproof effect and the best anti-aging effect

II. SBS coiled material waterproof construction process

1 The paving method of SBS coiled material waterproof can adopt hot-melt paving. This paving method can not only reduce the engineering cost of the waterproof layer, but also save the amount of adhesive, and avoid the hollowing of the waterproof layer

2. The ground shall be leveled with cement mortar. The leveling must be handled well, there must be no bulge, and the surface must be solid and shiny. Secondly, the base must be dry, and its moisture content must be below 9%

3. Wait for the dry base surface to be coated with SBS modified asphalt waterproof cold primer, which must be done once and ensure the smoothness of the coating. Generally, the best drying time is 6 hours in normal weather, and it is best not to stick feet

4. Place the waterproof coiled material in the right position, then light the blowtorch, use the blowtorch to heat the coiled material and the base course, and roll the coiled material forward immediately after the surface of the coiled material melts. Secondly, the heating must be uniform. When rolling, air and debris must not enter, and must be compacted and flattened. Then seal the edge with a trowel before the coil cools down, and then repair the seam evenly with a blowtorch. In this way, special attention should be paid to the edges and some complex parts of the coiled material to avoid edge warping

5. The construction method of double-sided coiled material is the same as that of single-layer. When paving the second layer, it should be separated from the joint of the first layer by about 0.3cm

6. Pay attention to the management and maintenance of gasoline and blowtorch during coiled material construction to avoid unnecessary industrial accidents caused by fire during construction

editor's summary: the above is about what is SBS membrane waterproofing and the construction process of SBS membrane waterproofing. I hope it can bring help to the majority of friends.
