When installing grain pvc decorative sheet, ensuring its flatness is crucial to the final decorative effect. Here are some key points.
First, the base treatment is the foundation. The wall or ground base must be flat, dry, clean and free of cracks. If the base is uneven, cement mortar or putty should be used for leveling first. The error should be controlled within the specified range. Generally, the flatness deviation should not exceed 3 mm per 2 meters. Only a solid and flat base can provide a good support for the installation of decorative panels.
Secondly, during the installation process, the installation quality of the keel directly affects the flatness. The keel should be made of qualified quality and suitable specifications, and should be installed strictly according to the designed spacing. During installation, tools such as a level meter should be used to ensure that the keel is horizontal and vertical, and the height difference between adjacent keels should not exceed the specified value, for example, not more than 1.5 mm. The keel should be firmly fixed to avoid loose displacement during the subsequent installation of the decorative board.
In addition, the cutting and splicing of the decorative board should be accurate. According to the installation location and size requirements, the grain pvc decorative sheet should be accurately cut, and the cutting edges should be neat and burr-free. When splicing, pay attention to the uniformity of the gap between the boards. Generally, the gap width is controlled at about 2-3 mm. Special splicing accessories or sealants can be used for connection to ensure that the splicing is smooth and smooth without height difference.
In addition, it is also critical to use a suitable fixing method during installation. The decorative board can be fixed with self-tapping screws, air nails or glue, but attention should be paid to the uniformity of the fixing force and position to avoid deformation of the decorative board due to improper fixing. For example, self-tapping screws should be evenly distributed on the edges and keels of the decorative board, and the tightening degree should be moderate to prevent excessive extrusion from causing the board to sag or bulge.
Finally, during the entire installation process, the flatness should be checked at any time. Tools such as rulers and level rulers can be used to measure the installed decorative boards. Once unevenness is found, adjustments should be made in time. After the installation is completed, the overall decorative effect should be comprehensively checked, and local unevenness should be repaired to ensure that the surface of the grain pvc decorative sheet is smooth and clean after installation, presenting a good decorative effect and enhancing the beauty and quality of the space.
