Due to the room type and the construction process, building materials have a certain wear rate during paving. In particular, tile wallpaper and Other wall decoration materials should be calculated as much as possible when paving, so as to avoid unnecessary waste. Wallpaper usage (volume) = room perimeter × room height × (100 + K) / square meter per roll, K is the loss rate of the wallpaper, usually 3 ~ 10. General standard wallpaper can be paved 5.2m 2 per roll. The size of K is related to the following factors: Wallpaper pattern size: Large pattern patchwork is complex to the flower, so the utilization rate is lower than that of the small pattern, so the K value is slightly larger; the need for the flower pattern ratio does not require less utilization of the flower pattern, and the K value is slightly larger; The arrangement pattern has lower utilization rate than the horizontal arrangement pattern, and the K value is slightly larger; Paste surface properties: Paste surface is more complex than normal flat wallpaper, K value is high; Paste method: use the stitching method to paste the paste stitching wallpaper utilization rate is high, K value is small; with overlapping cutting seam method wall paper wallpaper utilization is low, K value is large. Perimeter algorithm: Measure its overall length around the room, excluding floor-to-ceiling windows and embedding Large areas of monochrome are popular and easy to use. Small pattern wallpaper is easy to patch, and the utilization rate is relatively high. Large pattern wallpaper utilization is relatively low. Style closet. However, the general window area must be calculated. This value is the perimeter of your room.
