Before buying wallpapers, you need to estimate the amount of the wallpaper so that you can buy wallpapers of the same batch at once, reduce unnecessary troubles, and avoid waste. The amount of wallpaper is calculated using the following formula:
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, the wallpaper pattern size: large pattern seams on the flower complex, so the utilization rate is lower than the small pattern, so the K value is slightly larger; the need for the flower pattern than the flower pattern does not require low utilization rate, 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 complicated than ordinary flat surfaces, and the K value is high.
3, paste method: the use of stitching method paste paste stitching wallpaper high utilization rate, K value is small; with overlapping cutting seam method paste paper wallpaper 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 and determine the quantity before calculating the quantity.
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 in future repairs. Otherwise, there may be a color difference at the time of batch purchase.
