How to do gutter waterproofing, and what experience do you share?

The construction of the waterproof layer of the gutter and the eaves should first do a good job of additional reinforcement layer If asphalt-based waterproofing membrane is used, an additional membrane should be paved; If polymer modified asphalt waterproofing membrane or synthetic polymer waterproofing membrane is used, it is advisable to use a waterproof coating reinforcement layer with the same material properties.

In the process of pouring the floor slab of the rural self-built house, after the floor is poured, the gutter waterproofing is installed with a square strip or formwork, and a waterproof edge with a height of about 10 cm is poured with concrete.

The waterproofing of the gutter is very important, and when doing the waterproofing of the gutter, it is necessary to pay attention to the waterproof coating on both sides of the gutter and lay the waterproof membrane. Finally, the water leakage treatment is carried out.

The roof is a sloping roof with a gutter around it, which collects the water flowing down from the roof tiles into the gutter, and then flows through the gutter to the drainage outlet, and finally discharges to the storm water pipe.

First do the first waterproofing layer:

Laying a flexible waterproof layer, you can choose paint or membrane. Its construction conditions require that the moisture content of the base surface is not more than 9%, so it is suitable for construction in the summer after the hot weather and 5 consecutive sunny days. After completion, a water storage experiment should be carried out.

For example, to do paint waterproofing, take one cloth and two coatings as an example: after cleaning the base layer, brush the paint again, dry the film, lay a layer of glass fiber cloth carcass reinforcement material, and brush a layer of paint on the flattened surface to fix, and carry out the next coating construction after drying. The total thickness of the waterproof coating film should be more than 3 mm.

For example, after the construction of the waterproof membrane, after cleaning the base layer, brush the adhesive on the reverse side of the membrane and the base layer, paste and roll according to the elastic baseline from far and near, and finally check the seam end.

For people who live on the top floor or bungalow, they are no strangers to roof gutter waterproofing, once the gutter waterproofing is not done, it will bring great inconvenience to life, especially on rainy days, Zhihu long-term water leakage will form a "water curtain hole". Then the following is a brief introduction to some practices of gutter waterproofing.

1. The big reason for the roof leakage is that there is a problem with the original waterproof layer, so the original waterproof layer must be removed first. The second is to replace it regularly, so as to avoid the appearance of water leakage.

2. Clean up the grassroots level. When cleaning the base layer, it is necessary to clean all the foreign bodies, dust and debris on the surface of the base layer, especially in the shaded corners, which need to be carefully cleaned. After cleaning the base layer, it can be better coated with a new waterproof layer.

Although it may seem like a simple clean-up, it is actually a very important step.

3. Brush the waterproof layer. When coating the waterproof layer, it should be uniform, there can be no omission, and it is necessary to pay attention to the fact that the undried coating layer can not be polluted during the application process, so that the waterproof layer can be used for a longer time.

4. Apply the waterproof layer for the second time. Apply in the same way as the layer. It is also important to note that the waterproof material must not be irrigated until it has dried.

5. Check and accept, wait until the waterproof layer is completely dry, rinse the waterproof layer with water to see if there will be rain leakage.

After these five steps, the gutter waterproofing is complete. These seemingly inconsequential little acquaintances are still very important when they encounter difficulties!
