Final answer:
To prevent air from becoming trapped in sealant, make sure there is an escape path for air, ventilate the area properly, and apply the sealant smoothly to avoid creating air pockets.
Step-by-step explanation:
To prevent air from becoming trapped in the sealant during sealing operations, a few strategies can be employed. First, ensure there is a method for air to escape through the hole or gaps before the sealant hardens. Secondly, it is crucial to ventilate the area and follow the manufacturer's instructions.
Lastly, applying sealant in a way that avoids creating air pockets is essential, such as by using a smooth and continuous motion when applying the sealant, to displace air and prevent air entrapment.
