How to ensure the quality of metal-carved exterior wall decoration panels?

1. The flatness of the base wall is within 4mm.

2. The surface of the base layer must be firmly bonded, and there are no defects such as empty drum, weathering, dirt and paint that affect the bonding strength and quality.

3. If the wall of the base layer is leveled with 1:3 cement mortar, special tests should be carried out on the adhesion of the bonded slurry to the base wall.

4. Bonding glue ensures that sand, accelerator, antifreeze, polymer and other additives are not incorporated.

5, metal carved exterior wall decorative board should be cut to the standard size.

6, metal carved exterior wall decorative board, should be checked before construction, whether it meets its requirements.

7. The metal-carved exterior wall decorative board should be affixed to the point frame method. The application area of the bonding glue should not be less than 30% of the total area of the insulation board.

8. The joints of the metal-carved exterior wall decorative panels shall be tight and flush, and the gap between the plates shall not be greater than 2 mm, and shall be filled with insulation bars and smoothed.

9. There must be no adhesive between the board and the board.

10. The bonding operation of the metal-carved exterior wall decorative board should be rapid, and the bonding glue should not have skin before installation.

11. The right angle should be cut with a single plate, and the joint should be no less than 200 mm from the corner.

12. After the insulation board has been pasted for at least 24 hours, the next process can be carried out.

13. Do not lay mesh cloth when it rains.

14. The standard mesh cloth is overlapped by at least 100 mm, and the overlap of the yin and yang angle is not less than 200 mm.

15. If the polystyrene board is used as the insulation layer, a layer of mesh cloth may be added to the building below 2 meters or susceptible to impact.

16. Protect the finished part from the infiltration and erosion of rain.

17. When there is a foam plastic rod and sealing paste, it is required to provide a certificate of conformity and technical information. The diameter of the foam rod is 1.3 times the width of the slit.

18. Before the glue is applied, it should be ensured that the nodes are free of oil, dust and other impurities.

19. The sealing paste should completely fill the cavity of the joint and be tightly combined with the glue on both sides.
