The construction procedure of terrazzo flooring mainly includes the following steps:
Base treatment: First of all, the concrete base layer needs to be cleaned to ensure that the surface is free of impurities such as oil and dust. If necessary, it can be cleaned up with tools such as wire brushes. At the same time, it is necessary to ensure that the surface strength of the base layer meets the standard.
Find the elevation and elastic horizontal line: according to the design requirements, determine the elevation of the floor, and pop up the horizontal line on the wall as a reference.
Make a screed: pave the cement mortar screed. This process needs to be carefully observed to ensure that the top and bottom, left and right are aligned, and there is no uneven distribution of one short end and one long end.
Grid strip inlay: According to the design requirements, pop up the vertical and horizontal directions or pattern ink lines, and then divide the grid strips according to the ink lines. After the completion of the lattice strip, it should be cured for two days.
Maintenance: After paving the stone slurry, it is necessary to water and maintain it one day, and set up a cordon to prevent pedestrians from trampling.
Wipe the surface layer of stone slurry: measure the stone slurry according to the mix ratio, and carry out at least two operations to sweep the sticky slurry with hair to ensure that the stone particles are uniform. Then use an iron trowel to smooth and compact until the slurry is spread.
Test grinding, coarse grinding, fine grinding, grinding: Before grinding, test grinding is carried out to ensure that the stone particles are not loosened. A mechanical grinding stone is then used for grinding, and for small areas, corners can be ground using a small portable mill or by hand.
Cleaning: Wash with oxalic acid.
Waxing and glazing: Finally, the waxing and glazing operation is carried out.
The above is the construction procedure of terrazzo flooring, and each step needs to be operated in accordance with the specifications to ensure the quality of construction. At the same time, it is also necessary to pay attention to safety during the construction process to avoid accidents.
