One, what adhesive is used to attach the decorative panel?
Adhesive bonding is the most common method. This involves installing decorative panels onto the substrate after the flooring is complete, using adhesive and backing strips. The substrate should be prepared by the construction personnel in advance, with all necessary leveling and vertical alignment work completed.
The adhesive typically used for veneered panels is a combination of strong adhesive and white glue. White glue is used when pressing the door panel, while strong adhesive is used when bonding the veneer to the substrate.
Two. What are the reasons for the weak adhesion of decorative panels?
Reason analysis:
1、The decorative panels are not firmly bonded to the concrete surface of the walls and columns, resulting in an unsealed and porous bonding layer with gaps.
2、The materials used for bonding the decorative panel to the wall and column members do not meet the design requirements, and the mortar joints between the bricks are too large, resulting in gaps after shrinkage.
Measures to prevent:
1、The installation of facade panels should not be carried out immediately after the exterior wall construction is completed. It is necessary to wait for the concrete to initially set before proceeding with the installation.
2. The quality of the bonding material should meet the design requirements, and the size of the mortar joints should be constructed according to the design specifications.
