Chapter I Construction Sealants Functional Classification and Technical Requirements Chapter II Construction of Building Sealants Chapter III Construction Joint Seal Design and Seal Selection Chapter IV Construction Sealant Construction and Analysis of Sealing Defects Determined in Joints and Sealing Materials Afterwards, a successful and reliable seal relies entirely on the quality of the sealing operation. Not only does it require correct and skilled handling techniques, but it must also be taken seriously and patiently to avoid defects. A large number of facts have shown that the inadvertent sealing construction is an important cause of leakage, and it is very difficult to check the leakage source and restore the seal. It is time-consuming, labor-intensive and adds unnecessary expenses. 1. Seal construction preparation 1.1 Construction conditions Before construction, it is necessary to first check whether the purchased sealant meets the requirements of the construction specification. It should be familiar with the storage, mixing, use conditions and usage methods provided by the supplier, and the specific provisions for safety precautions. The temperature at the time of construction is best near the average annual temperature, generally
