At what temperature is waterproof coating most suitable for construction, waterproof and intelligent waterproof?

Waterproof coatings are mostly liquid or contain liquid components and contain a lot of water.

When the temperature is below 0 degrees Celsius, it is easy to freeze. After freezing, the bonding ability of waterproof coating will be reduced, and the waterproof effect will also be reduced, so it is not allowed to construct outdoors under the condition of 0 degrees or below.

When the temperature is too high, water will boil at 100℃; In addition, after the waterproof coating is painted, the waterproof coating will have a chemical reaction, and the waterproof layer will crack if the temperature is too high. As we all know, water is needed in the curing process of waterproof coating after brushing, one is to cool down, and the other is to need water for chemical reaction.

Therefore, the waterproof coating is best used in the environment of 5℃-40℃ to avoid high temperature, low temperature and outdoor rainy weather.

In order to ensure the quality of waterproof construction in winter and the safety of construction personnel, winter construction enterprises are required to carry out construction in strict accordance with construction specifications. Engineering masonry materials are strictly forbidden to be used in engineering after being soaked in water and frozen. Roofing waterproof engineering and external wall insulation engineering should be carried out in windless and sunny weather. When the outdoor temperature is below 5℃, it rains and snows, or the base is wet and frozen, it is forbidden to carry out roof waterproof construction and external wall insulation engineering. When the outdoor temperature is lower than 2℃, outdoor painting construction is strictly prohibited.
