  • In order to prevent the sealing adhesive from being damaged when the joint expands, the joint shoule be stuffed with a suitable backing material, and the width of the backing material shoule be greater than 25% of the joint width to conrol the thickness of the sealant.

  • A bevel shoule be cut at the outer mouth of the sealing paste tank, and then a squeeze gun shoule be installed to squeeze the sealing paste of the joint. The thickness and width of the sealing paste should be uniform and meet the sealing requirements.
