The number of bricks = (decoration area/area of ??each tile) The paving materials used when laying ceramic tiles mainly include: cement, sand, 108 glue, caulking agent, etc. The caulking agent is used for joint processing after paving.

1. For a normal square rough wall, to paste 100 square meters of wall tiles, 35 bags of cement and 2.5 cubic meters of sand are needed. If the cement is 20 yuan/bag and the sand is 60 yuan/cubic, it will take 850 yuan, plus 5-6 bags of caulking agent.

2. The labor cost for going upstairs is 35 bags of cement. 2.5 cubic meters of sand should be about 120 bags (cement bags). Calculated at 0.5 bags/floor. Calculated based on the 6th floor, the price is 350 yuan. about.

3. The above is only the normal cost of pasting wall tiles, but now the rough walls are irregular, so the cost of cement, sand and transportation costs are higher.

The cost of auxiliary materials is about 9-10 yuan/square meter. The total cost of auxiliary materials and transportation is about 13 yuan/square meter.

4. When dry-paving floor tiles are used, the amount of cement and sand used is much greater than that of wall tiles. Therefore, the amount of various materials used greatly exceeds that of wall tiles. Subsequently, laborers go upstairs. Fees will also increase accordingly. The cost of auxiliary materials and transportation for floor tile pasting is about 16 yuan/square meter.
