How to construct sand free leveling What are the functions of sand free leveling materials?

The craftsman sand screeder is a new type of ground leveling construction material, using the principle of foamed cement, cement foaming technology replaces the traditional yellow sand, shortening the time of mixing cement mortar. The construction method is as follows:

Clean up the debris in the construction area: Investigate whether there is debris in the construction area in advance, whether the ground is cleaned, and be sure to clean up the loose dust surface.

Punching positioning: first determine the elevation, take the construction horizontal line as the benchmark, vertically measure the leveling elevation, pay attention to the surrounding wall elevation control line, and the elastic line evenly divides the spacing of the reinforcement.

Fixed-point positioning: according to the position of the punching line, every 1 meter or so, the fixed-point of the positioner, and use an electric drill to punch holes, lay out the positioner, and install the punch bar to the notch after the layout.

Sprinkle water and moisten the base layer: After the installation and leveling of the rib strip, the ground and wall (30cm high) must be wetted, and the cement dry powder must be sprinkled on the ground at the same time, and the construction can be carried out after sweeping with tools (remember that there can be no open water on the construction surface).

Stirring leveling material: pour a certain amount of water into the mixing equipment, and then bring in the cement with a good ratio, as well as the masterbatch of the leveler with a good ratio, and mix and foam after a certain period of time after pouring all of them.

Unloading: Pour the stirred machine into the construction area and evenly spread it into the construction area with a shovel.

Preliminary leveling: Preliminary leveling of the construction area is carried out with a stainless steel trowel.

Laying the net: Spread the fiber mesh onto the leveled leveler material, and then use a stainless steel trowel to pat the fiber mesh until the fiber mesh is submerged in the leveler material.

Scraping: Then use a stainless steel trowel to smooth the leveler material until the surface is flat and smooth.

Repeat the above steps until the entire area is leveled.

Generally speaking, the ratio of cement mortar in home decoration is about 1:3 (cement:sand), and the amount of water should be based on the visual perception of the scene, not too dry, not too thin.

If the thickness of the screed is 3cm, then a bag of cement (the standard net content of bagged ordinary Portland cement is 50 kg) with 230kg of sand (about cubic meters) can lay a screed layer of 5 square meters. Inlay material: ordinary cement, white cement, medium sand, 107 glue 1) The wall is inlaid with various porcelain tiles with ordinary technology, and 11kg of ordinary cement, 33kg of medium sand, and 2kg of lime paste per square meter.

2) On the cylinder surface, 13kg of ordinary cement, 27kg of medium sand, and 3kg of lime paste are required for inlaying various porcelain tiles with ordinary technology. 3) The ordinary process of the ground is inlaid with floor tiles and mosaics, and 34kg of ordinary cement and medium sand are required. 4) When the wall is inlaid with porcelain tiles, 107 glue is often added to the cement, and 12kg of ordinary cement, 13kg of medium sand, and 107 glue are required per square meter.

5) Cylinder: 14kg of ordinary cement, 15kg of medium sand, and 107 glue per square meter. 6) The white cement that needs to be wiped after inlay, about every square meter.

7) The amount of cotton silk used for scrubbing the porcelain sheet is about 1kg 100. 8) Adhesive floor tiles, 1kg glue can be glued to 4 6 floor tiles.

Sand-free leveling is a new type of ground leveling construction method of craftsmen, using the principle of foamed cement, cement foaming technology replaces the traditional yellow sand, shortening the time of mixing cement mortar. Combined with the punching process of ground leveling, workers can also make the flatness that decades of old mason masters can make with the help of leveling tools. Craftsman sand leveling has moisture-proof, noise-reduction, earthquake-resistant and ultra-light performance, and does not contain benzene, formaldehyde and other harmful substances that endanger people's health.

The construction method of screeder sand leveling: now the ground is fixed with the locator, and then the leveling rod is fixed on the locator, and then the partition is fixed. In this way, you can start to start the mixer, start the preparation of cement foaming, and after the cement and foam are fully stirred, you can start to pour the material, open the valve, and then use a leveling trowel to evenly distribute the backfill on the ground from top to bottom, move the excess material to the outside, and then carry out local leveling.

Leveling does not use sand, saves labor and sand, resists pressure and environmental protection, and recognizes the craftsman.
