How to make the gutter waterproof and durable

The most lasting way of roof gutter waterproofing: strengthening treatment and laying waterproof coiled material.

First, strengthen handling.

Polyurethane coating waterproof material is used for treatment, and the ratio of coating material A to coating material B is 1: 1.5, and then evenly stirred and coated around the gutter and on the gutter wall. The width of the painting should not be less than the edge of 20 cm. The coating thickness should be controlled at about 2mm, and the construction of the next procedure should be started 24 hours after coating.

Second, the waterproof coiled material shop is stuck

1, laying. When using polymer modified asphalt waterproofing membrane, when paving the membrane, it should be rolled from the center of the paved membrane to both sides with a press roller while it is hot to exhaust air.

Step 2 grind. The lap width of coil shall not be less than 100mm, and the coil end must be sealed with polyurethane caulking paste. After sealing and curing, a layer of polyurethane coating waterproof material is painted on the head.

3. Make a protective layer. The protective layer adopts C 10 concrete.

Precautions for roof gutter waterproofing

1. In the process of decoration, the position of the gutter should be arranged in advance, and the flow direction and drainage of rainwater should be designed according to the reasonable design direction of the pipeline. So for this project, the first step is to consider how this system is set up in this room.

2. For how to waterproof the gutter, the design of the gutter itself is very important. Its own length and size need to be considered according to the actual situation of the house. The depth should not be too high, but it should not be too low. For the gutter, the height of five to ten centimeters is the most suitable. The width needs to reach ten to twenty centimeters, preferably.

We should consider the influence of external factors. The local climate and temperature will affect the waterproofing of the gutter. This requires a certain understanding of the house to avoid changes in the wall of the house due to weather in the later period, so that cracks appear in the gutter and rainwater penetrates into the wall. In addition, we should also pay attention to whether the pipeline laying is reasonable to avoid blockage, or whether the low temperature in winter will lead to internal blockage of the trench.
