Anonymous users2024-01-24This question is a question of how many years (from civil construction to renovation) can never be understood (absolutely). Theoretically it is not difficult to calculate. But there are many unknowns, and some of them can be accurate (such as the horizontal error of the ground, as long as you are not afraid of trouble).
Some of them just can't figure it out. For example, the accuracy of the ratio of sand and cement.
In addition, the particle size of the sand affects the amount of cement (the finer the sand, the more cement is expensive).
The size of the floor tiles is different, and the amount of mortar should be different. This is a necessary requirement for the operation of bricklayers. The amount of mortar for the tiles should be larger.
THE THICKNESS OF THE MORTAR IS TOO THIN, THE BRICKLAYER CANNOT OPERATE (THE LEVEL CANNOT BE ADJUSTED), THE SMALL AREA IS LOCAL, THE HIGHEST AREA OF THE GROUND CANNOT BE TOO LARGE, AND THE LIMIT CANNOT BE LESS THAN 25MM. It couldn't be thinner. THE NORMAL THICKNESS SHOULD BE ABOUT 30-40MM (BUT THE HORIZONTAL ERROR OF THE ORIGINAL GROUND IS TOO LARGE, SOMETIMES IT REACHES SIX TO EIGHT CENTIMETERS, AND IT ALSO HAPPENS FROM TIME TO TIME.)
Look, can cement still be accurate? ）。600MM FLOOR TILES ARE CORRESPONDINGLY THINNER AND NOT TOO LARGE.
IT IS EASY TO OPERATE, AND 40MM THICK IS THE BEST. (In addition, the mortar of the floor tiles is located on the original ground, not by the combination of dry mortar.)
The mortar is thin and easy to cause hollowing. Note. ）
EMPIRICAL CALCULATION METHOD: SAND IS CALCULATED ACCORDING TO THE GROUND AREA OF 40MMX, AND CEMENT IS CALCULATED ACCORDING TO EACH FLAT BAG. Finally, make it up. Note: The maximum error is the horizontal error of the original ground. If you have time, it's best to copy the flat first, see what the situation is, and take an average.

Anonymous users2024-01-23Generally, it is 1:3 cement mortar priming, plain cement slurry paste, and the mortar thickness is 20mm.
Cement is required, medium sand.
It should be 80 square meters of room, 80 square meters of bathroom is very large, I have been doing waterproof work for many years, according to personal experience, a bathroom needs to use a large amount of waterproof materials in 2 barrels, can paint 30 square looks, bathroom waterproofing to flexible waterproof materials. Hope it helps!
3. The brand of all wall tiles is not the same, the most inferior has a few dollars a piece, there are dozens of good ones, the price difference between Guangdong bricks and Shandong bricks is larger, and the general market is Guangdong bricks.
We have the cheapest integrated ceiling here for 138 square meters. It is laminated. What metal brushed, printed, are very expensive, in fact, there is no need. If you have the money you can buy a printed one, it's very beautiful.
