Three-sided adhesion prevention tape when the joints are shallow. Reasons for preventing three-sided adhesion: The joints are stretched due to the temperature difference of the members, the building is shaken, and the movement against the sealing due to the distortion is working.
If three-sided bonding is applied to such joints, the sealant will not move freely and will not be able to perform its original function. As a result, the sealing material may come off from the parts and cracks may occur.
To prevent this phenomenon, it is necessary to prevent three-sided adhesion. Ideal for shallow joints that cannot be packed with backup material!
