Can the leaking foam glue on the roof of the color steel house be waterproof?

No. Blowing agent.

It is useful for a while, but it is easy to age and easy to fall off. It is useful to fill the stuff with a foam stick and then hit the weathering glue.

Foam glue is polyurethane foam.

Series, filling, water resistance, weather resistance are good, and the adhesion is relatively strong, ** is relatively low, but it will fall off after long-term use, because the bonding performance of foam glue is general, and the advantage is that it can be bonded in a large area and without gaps.

Foam glue is mainly used to fill large gaps and has no strength.

Foam glue is a type of rubber. Also known as sponge rubber. Vulcanized rubber with a spongy porous structure.

There are open, closed, mixed and microporous. It can be made into soft rubber or hard rubber products. Lightweight, soft, elastic, and not easy to transfer heat. It has the functions of shock resistance, impact mitigation, heat insulation, sound insulation, etc.

Extended information: Construction plan for roof leakage.

1. It is necessary to remove the previous waterproofing, such as paint, membrane, etc., if it is made of mortar waterproofing, it can be removed without shoveling.

2. Repair the cracks. After the repaired cracks are dry and firm, start waterproofing.

3. The first layer is made of flexible waterproofing, that is, special anti-aging waterproof coating for roofing.

4. The second layer is made of mortar waterproofing (mortar waterproofing agent), which can protect the flexible waterproofing of the bottom layer while waterproofing.

Waterproofing of roofs. A single waterproof material can not be used, it must be constructed in a rigid and flexible way, and the flexible waterproof stretch is good, and the waterproof layer will not be damaged if there is a slight settlement or deformation. Rigid waterproofing (i.e., mortar waterproofing agent) can play a protective role while waterproofing, and the waterproof layer is not easy to be damaged.

Color steel room.

The foam glue is just a filler, if it has been torn or not tightly laid, it will not only leak rain, but also leak air. It is best to put weatherproof glue on the outside, waterproof and sealed. Using only foam glue is a sign of cutting corners.

Go to the market to buy weathering glue, if you fix it yourself, patiently coat and fill the seams, you have to make it tight, and get it several times. If it is still under warranty, let the company or person who works for you reorganize you. Shenyang Angwei doors and windows.

Foam adhesive belongs to the polyurethane foam series, filling, water resistance, weather resistance are good, and the adhesion is relatively strong, relatively low, but it will fall off after long-term use, because the bonding performance of foam adhesive is average, and the advantage is that it can be bonded in a large area and without gaps.

Hello dear, I'm glad to answer <> for you

Answer, the color steel roof uses waterproof glue, feasible color steel sandwich panel A B glue, color steel composite plate A B glue. AB glue is another name for two-liquid mixed hardening glue, one liquid is the glue, one liquid is the first chemical agent, the two liquids can be hardened by mixing, and it is not necessary to rely on temperature to harden and mature, so it is a kind of hardening glue at room temperature, and it is sometimes used to make models. Generally used in industry.

AB adhesive is the name of a two-component adhesive that is destroyed early. AB glue with acrylic, epoxy, polyurethane and other components is commercially available. When used in the factory, in order to distinguish it from the conventional large cans (1 kg and 2 kg sets), epoxy resin, the abbreviation of the toothpaste tube is AB glue (the eye-catching name on the box).

1. Cut a fifteen-centimeter-long trench at the junction of the roof and wall of the color steel house, and then stuff it into a section of color steel plate, which should not be stuffed too much, about two to three centimeters, and finally stabilize the color steel plate with screws.

2. Carefully check the source of water leakage, if the screw is loose, you need to tighten the screw, and then apply a layer of weather-resistant glue around the screw, which can improve the service life of the screw to a certain extent and avoid rain leakage.

3. The full paving method can also be used to lay the special waterproof membrane for the color steel house on the roof horizontally, which can not only make the roof achieve a good waterproof effect, but also ensure that the roof is not corroded.

After Langxing waterproof front-line construction personnel in thousands of construction experience summary, at present, most of China's steel structure color steel roofs due to installation and construction, roof elastic deformation, roof vibration and other reasons caused by water leakage phenomenon is more serious, in the northern region because of the temperature change is obvious, the phenomenon is more prominent, and even some steel structure manufacturers in their own plants, office water leakage phenomenon is not uncommon, seriously affecting the property safety of the owner and the normal production and office order. According to the analysis, roof leakage is mainly concentrated in the vertical and horizontal lap joints of metal color steel tile roofs, roof ridges, lighting tiles, fan bases, chimney pipes, all screws on the roof, gutter sinks, parapet joints and other node parts, especially in the roof drainage ditch area.

The reasons for water leakage in the gutter area of the roof are as follows:

1) The interface between the downspout and the downspout is leaking.

2) The elevation of the downspout is not in the lowest position, the gutter has accumulated water for a long time (the original auxiliary waterproof layer is aging), and the standard section of the sink is leaking.

3) The number of downspouts is not designed enough (or the diameter is small and the foreign matter is blocked), the drainage is not timely, and the rainwater flows into the room from the gap between the edge of the gutter sink and the roof panel.

The waterproofing requirements of the factory floor are high, and the roofing system is more complex. There are many roof skylights, fans, and various roofing pipes, and the roof gutters are all inner gutters, so it is very difficult to waterproof the roof.

When the rainfall is heavy in summer, if the drainage of the gutter rainwater inlet is not smooth, and the junction between the gutter and the roof panel is not tightly sealed, the water in the gutter is easy to overflow the edge of the gutter and pour into the roof. In spring, the snow melts at the gutter, and meltwater seeps into the roof at the junction between the gutter and the roof panel.

Because the single-slope roof is long, the expansion and contraction deformation of the roof panel is large under the condition of temperature change, and it is easy to tear the waterproof layer at the edge of the gutter and lose the sealing effect. The commonly used method of sealing the edge of the roof panel is to close the junction between the roof panel and the gutter with a plug and a sealing strip, and the sealant or sealing strip of this method is easy to fail at low temperature, and the waterproof sealing layer is also easy to break after the roof panel is expanded and deformed, which eventually leads to leakage at the gutter. Therefore, it is advisable to choose a waterproof material that is resilient and not affected by temperature.
