The following aspects need to be paid attention to when spraying waterproof coatings:
1.Construction environment: The construction of waterproof coating should avoid low temperature, high temperature, humidity, exposure to the sun and other harsh environments, and the construction temperature should be between 5-35.
2.Base surface treatment: Before spraying, the base surface needs to be cleaned to ensure that there is no oil, dust, moisture, etc., and keep it dry. For uneven and uneven defects, they should be repaired.
3.Coating thickness: The coating thickness should be controlled when spraying waterproof coating, too thin or too thick will affect the waterproof effect. According to different waterproof coating requirements, the general coating thickness should be between 1-2mm.
4.Spraying skills: When spraying, it should be kept even, and there should be no exposed bottom or accumulation. Cross-spray is applied horizontally and vertically, followed by a forward spray to ensure an even coating.
5.Protection measures: Before the waterproof coating is dried, it should be avoided to step on and drench in water to avoid damaging the waterproof layer.
6.Drying time: After spraying, the waterproof coating needs to wait for drying, generally 2-4 hours, and the specific time depends on the waterproof coating. During the drying period, the basal surface should be kept dry to avoid moisture or moisture intrusion.
7.Safety matters: Protective equipment should be worn during construction, such as gloves and masks. At the same time, good ventilation should be maintained during construction to avoid long-term contact.
The above are a few aspects that need to be paid attention to when spraying waterproof coatings, for reference only.
