Precautions during sizing?

Make sure that the depth of the sealant is not greater than the width. If the gap between the two substrates is large, it is necessary to insert a fillet to improve the performance of the sealant. Use appropriate tools to level the sealant to make the surface more beautiful; At the same time, the sealant is pressed into the joint surface, thus helping to eliminate air pockets or gaps in the bonding layer.
