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 5.2 square meters per roll.
The size of the K value is related to the following factors:
1. Wallpaper pattern size: large pattern patchwork is complex for 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 patterns arranged in the same direction have lower utilization rate than the pattern arranged in the horizontal direction, and the K value is slightly larger.
2. Paste surface properties: The paste surface is more complex than ordinary flat surfaces, and the K value is high.
3. Pasting method: Use the stitching method to paste the wallpaper on the stitching seam, the utilization rate is high, K value is small; with the overlapped cut stitching method wallpaper paste utilization is low, K value is large.
From the above formula, we can see that even if it is the same room, use wallpapers of different textures and different designs, the amount of which is different. At the time of purchase, you must consult the salesperson in detail, determine the quantity and then calculate the amount. You can also ask someone to measure it for you. After calculating the approximate amount according to the above method, it is recommended that you buy one more volume on this basis, leaving a margin for use when repairing later.
(Pumi wallpaper reminds you: When you purchase wallpaper, you must measure it clearly. If you buy less, there may be a color difference for the twice-ordered product)
