1. Calculating the wall area The decorative materials of the wall (including cylinder) generally include: paint, stone, wall tiles, wallpaper, soft bags, partitions, skirting lines, etc. Different materials have different calculation methods when calculating the area. The area of paint, wallpaper, soft bag and partition is calculated by multiplying the length by the height, and the unit is "square meter".
2. The length is calculated according to the net length of the bearing wall; Height: calculated from the indoor ground to the bottom of the floor without clapboard, and from the top of clapboard to the bottom of the floor with clapboard; If there is a ceiling, add 20cm from the indoor floor (or the top of the dado) to the lower edge of the ceiling.
3. The area occupied by doors and windows shall be deducted (1/2), but the skirting line, mirror hanging line, the hole area with a single area within 0.3m2 and the area where the beam head meets the wall surface shall not be deducted. When sticking stones and wall tiles, the actual paving area is calculated as "square meters", and the installation skirting board area is calculated as the net perimeter of the interior wall of the house, and the unit is meters. ?
4. Calculate the top surface area. The decorative materials of ceiling (including beams) generally include paint, ceiling, top corner line (decorative corner flower) and lighting ceiling. The construction area of suspended ceiling is calculated as "square meters" according to the net area between walls, and the area occupied by partition walls, columns passing through suspended ceiling, chimneys and affiliated chimneys is not deducted. The length of the top corner line is calculated in meters according to the net perimeter of the interior wall of the house.
