Notes on terrazzo floor construction in floor decoration.

Grinding stone floor is a common method of floor decoration. Because of its low price and simple operation, it is popular. So how to operate? What problems should we pay attention to? The following is the content of the construction method of grinding stone ground.

Grass-roots treatment, before construction, the grass-roots must be cleaned without oil and dust, and the cement slurry at the grass-roots level can be treated with wire brush. Find the standard high elastic horizontal line, measure the elevation of the grindstone surface according to the elevation line on the wall during the construction of the grindstone ground, and mark it on the wall to ensure that the elevation of each room must be consistent.

Before the construction of the grindstone ground, first of all, mortar should be plastered to level the ground, and cakes can be pasted first to ensure the flatness of the leveling layer. After the ash cake mortar hardens, use horizontal bars and horizontal bars. The base is wet and brushed with cement slurry. The water-cement ratio is 0.4 ~ 0.5, and the area should not be too large. Leveling with the mortar brushed with 1:3, and leveling with a 2m-long scraper. Brush. After the flat mortar is cleaned, the next step of construction will be carried out 24 hours later.

Brush the cement mortar of the same grade, and then spread the terrazzo mixture. Fill holes and small gaps in the surface with a 60-90 diamond mill. If they fall, they must be filled. The surface must be polished and smooth. After grinding, wash with water. Then use 200 diamond to polish the surface until it is exposed evenly and no stone particles appear. When waxing, apply a thin layer of wax on the machine base, and install it on the grinder with linen and grindstone after the stone floor construction is completed. This process must be carried out twice to know the smoothness of the cleaning quantity.

The stone is uneven because the ground is uneven. Especially when there are footprints on your feet, if you don't deal with them in time, it will inevitably sink slightly at the footprints. In addition, if you step on the soft ground, the stone at the footprint will sink and the cement slurry on it will increase. When polishing, the slight subsidence of footprints affects polishing. Therefore, in the construction of grinding stone floor, the stone surface is uneven and not clear enough. The solution to this phenomenon is that operators need to arrange construction procedures to avoid a large number of surface dispersion as much as possible. In addition, try to wear flat-bottomed rubber shoes when constructing the millstone floor, and don't wear high heels or obvious shoes.

Spline exposure is uneven, and spline has a certain decorative effect. If it is intermittent, it will affect the decorative effect of the ground. The main reason of uneven grid appearance is uneven surface. Because the surface cement slurry covers the grid, it is not allowed to be polished when grinding the stone floor, which causes obstacles. It is also possible that the cement slurry is too thick and worn off after polishing, so the grid is still covered with a small amount of cement slurry and can't stop.

In addition, the height of the spline is inconsistent, and the height itself is different. Then when filling the ash, it will inevitably lead to the grating of a single component being covered too much. This kind of problem in the construction of grinding stone ground is mainly to control the elevation of the upper part of the grid. When the grids are arranged neatly, cable inspection is carried out, and errors are found to change in time. The above is the introduction of ground construction.
