Waterproofing is very important to every family. When we choose to decorate, we don't know how to do it because we don't know about the decoration. In order to better waterproof, we need to have a certain understanding of waterproofing. So everyone knows what needs to pay attention to the waterproofing of the roof? Today, Xiaobian will take a look at the waterproofing method of the roofing and what are the main points of the roof waterproofing!
What is the method of waterproofing the roof?
1. Base treatment, check the quality and dryness of the leveling floor and clean it. After meeting the requirements, apply the base treatment agent to ensure that the painting area can meet the construction needs of the day. After 4 hours of painting, the coil can be laid.
2, construction process, base surface cleaning, repairing → coating base treatment agent → additional reinforcement treatment at the node → positioning, elastic, trial shop → paving coils → end processing, node sealing → cleaning, inspection, finishing → Protective layer construction.
3. Construction sequence: When constructing the waterproof layer, the nodes, additional layers and roofing drainage should be treated first, and then the construction should be carried out from the lowest elevation of the roof. When paving gutters and cornices, the direction of Yishun Gutter and Mouth shall be reduced to reduce overlap. During the construction, the construction shall be carried out according to the principle of first high, then low, first and then near.
4, the lap joint method, the lap joint method is used when laying the coil material, the lap joints of the adjacent two coils should be staggered, the lap joint of the steel roof sloping roof is overlapped in the direction of the water, and the connection perpendicular to the ridge direction The seam is slid along the dominant wind direction.
What are the main points of roof waterproofing?
1. The base treatment agent is evenly applied, and the base layer, the periphery, the corner and the like are brushed with the brush before the large surface; the base treatment agent, the joint adhesive, the sealing material, etc. should be coated with the coil material. Compatible.
2. The surface of the coil should be cleaned before construction; when hot-rolling the coil, the mastic should be evenly coated, compacted and compacted to ensure the bonding ability of the waterproof layer of the coil and the base.
3. It should not be constructed in rainy days, heavy fog, snowy days, windy weather or when the average ambient temperature is below 5 °C, and the base layer should be protected from moisture.
4. According to the use environment and climatic conditions of the building, select the appropriate waterproofing membrane and paving method. After the construction of the last process, it should be inspected and qualified, and proceed to the next process.
5. Before the large surface of the coil is laid, the joint sealing treatment, the additional layer and the roofing drainage, the detailed structure treatment, the divisional joint treatment, etc. should be done first. The construction should be carried out from the lowest elevation of the roof; When shovel is rolled, it should be laid in the direction of Yishun Gutter and Gully, and be laid from the water drop to the direction of the water line to minimize the overlap.
6. The direction of the upper and lower coils should be laid correctly and should not be laid perpendicular to each other. The joints of two adjacent coils should be staggered by more than 300 mm.
When we do roof waterproofing, what we need to consider is how to do it, and it is also important to learn how to do it. The above is what Xiaobian today introduces for everyone, and the main point of waterproofing of the roof is here. If you want to know more information, please continue to pay attention to the decoration home.
