When installing wood grain pvc decorative sheet, the treatment of corner joints directly affects the overall decorative effect and durability. It is necessary to start from the details to take into account both beauty and firmness. The corner joints of PVC decorative sheets involve the transition between the wall and the floor, ceiling, corners and different shaped surfaces. Each joint needs to take corresponding measures according to the specific location and environmental characteristics to make the joints between the panels naturally hidden and ensure structural stability.
When handling the corner joints between the wall and the floor, the flatness of the floor and the wall must be ensured first. If there is a gap between the bottom of the wall and the floor, it can be filled and leveled with putty or caulking agent first, and then the decorative board can be installed after drying. Usually, a skirting is installed at the bottom of the wall to cover the joint. Choose a PVC skirting with a color similar to the wood grain pvc decorative sheet and fix it to the bottom of the wall with special glue or buckles. During installation, the length of the skirting needs to be cut according to the size of the wall. The joints can be spliced at a 45-degree angle to make the interface more concealed. At the same time, the skirting and the bottom of the decorative board should fit closely to avoid gaps that affect the appearance.
The connection treatment of the corners is the focus of corner construction, which is divided into two situations: positive corners and negative corners. For positive corners (corners protruding outward), positive corner lines can be used for wrapping. First, cut the positive corner lines according to the height of the corners, then apply an appropriate amount of PVC special glue on the back of the lines, align them with the corners and gently press and fix them to ensure that the lines fit closely with the decorative panels on both sides. The interface of the lines also uses 45-degree bevel splicing to make the lines at the corners continuous and smooth. For negative corners (corners that are concave inward), the edges of the decorative panels on both sides need to be accurately cut so that the panels can be naturally butted at the negative corners. If the joints are not smooth enough, negative corner lines can be added to cover them. The installation method of the lines is similar to that of positive corners. After being fixed with glue, the joints can be effectively hidden, and the anti-collision ability of the corners can be enhanced.
Corner lines are often used to connect the corners of the wall and ceiling. The material selection of the corner line needs to be coordinated with the wood grain pvc decorative sheet. Before installation, measure the angle between the ceiling and the wall, and cut the joint of the corner line according to the angle. When installing, start from one end of the wall, close the corner line to the junction of the ceiling and the wall, and fix it with nails or glue. Note that the nail holes should be hidden or repaired with putty later. If the length of the corner line exceeds the length of the board, the joint needs to be beveled at 45 degrees to ensure the overall continuity of the line, so that the connection between the wall and the ceiling forms a natural transition, which not only covers the possible gaps, but also adds a sense of decorative hierarchy.
The corner connection of different planes or shapes needs to be handled flexibly according to the specific structure. For example, when connecting the wall and the column, you need to measure the size of the column first, mark the position of the column on the decorative board, and use a cutting tool to open the corresponding notch so that the decorative board can wrap the column. The edges of the gaps should be polished to avoid the burrs affecting the appearance. The gaps between the decorative panels and the columns can be filled with sealant and then covered with decorative strips of the same color as the panels. When there are obstacles such as switches and sockets on the wall, it is necessary to accurately drill holes in the decorative panels. The edges of the holes should also be polished. After installation, the gaps should be covered with a frame to make the joints neat and standardized.
Edge sealing is crucial to the durability of corner joints. The cut edges of wood grain pvc decorative sheets are susceptible to moisture or wear, so the exposed edges need to be sealed after installation. PVC edge banding strips of the same color as the panels can be used and pasted on the edges with hot melt glue or special glue. The length of the edge banding strips should be consistent with the edges. Press hard when pasting to ensure that the edge banding strips are tightly combined with the panels. For curved or irregular corners, the edge banding strips can be heated and softened first, and then shaped according to the curvature and pasted so that the edge banding strips can fit the shape of the corners, which not only protects the edges but also makes the overall appearance neater.
When dealing with the edge joints, the thermal expansion and contraction characteristics of PVC materials must also be considered. When cutting boards or lines, a certain expansion gap must be reserved, especially in an environment with a large temperature difference. The gap width is usually not easily visible to the naked eye to avoid deformation or cracking of the corners due to material expansion. At the same time, the choice of glue must conform to the characteristics of PVC materials. Avoid using highly corrosive glue to prevent damage to the surface of the board. After the installation is completed, it is necessary to check whether all the corner joints are firm, whether there are looseness or gaps, and repair them with caulking agent or sealant in time to ensure that the corner joints are both beautiful and durable, making the installation effect of the wood grain pvc decorative sheet more perfect.
