Because this is a large-area waterproof roof, flexible materials used in home decoration cannot be selected, and this general flexible material is not suitable for outdoor waterproof parts. Generally speaking, outdoor waterproofing is the choice of coiled materials. Now the commonly used outdoor waterproofing membrane is the improved SBS waterproofing membrane. This kind of waterproofing membrane is divided into two kinds, one is self-adhesive cold-adhesive waterproofing membrane. The other is the conventional need to lay the coil with fire-bake and hot-melt method.
When doing waterproofing, my personal suggestion is to choose the kind of waterproofing membrane that requires hot-melt construction. Personally, I have always felt that the self-adhesive waterproofing membrane laid by the cold bonding method is not as firm as the waterproofing membrane laid by the hot-melt method.
There are many brands of waterproof membranes. Since we are familiar with Yushen, Tianyu, Heavy Rain, Yuhong, etc., the quality of the waterproof membrane is good and can be selected. Waterproof Coating Company
Key points of roof waterproof construction:
The roof waterproof construction step is also a very critical step, which is the treatment of the grassroots. First of all, we need to clean the roof that needs to be waterproofed. Personally, I suggest that everyone should rinse the entire roof with water, without any impurities and floating dust. We must ensure that the foundation is firm and clean.
The second step is to deal with some weak links in the roof. When we carry out large-area waterproofing construction, we must deal with all weak parts in advance. These parts include the front of the pipe, the front of the flue, and the gutter.
The three steps are to lay the coil. Before laying large-area coils, the first step is to brush the primer. After laying the primer, lay the coiled material. There are several issues that need to be paid attention to when PU waterproofing membranes are applied: First, the overlap length of the membranes should not be less than 100mm. The second is that all seams must be glued firmly. Polyurethane waterproof coating
Matters needing attention in the construction of roofing waterproof coiled materials. It is also necessary to pay special attention to the place where the coil and the guardrail around the roof meet. At this time, the coil must be turned to the upper part of the guardrail, and then press the top of the coil to ensure that the coil does not leak here. This is a very important point.
Protective layer construction
After all the coils are laid and pasted, carefully check whether there are bubbles, bulges, and special connections. After confirming that there is no such problem, the construction of the protective layer should be carried out in time. To ensure the construction quality of the coils we laid.
