Terrazzo floor construction method
1, the leveling layer adopts 1: 3 hard cement mortar, then leveling, and then compacting and leveling the mortar.
2. Grid mosaic. Next, we will make a figure-eight long seat with pure cement slurry and embed it firmly. At the same time, the iron wire worn by the copper bar should be embedded. It should be noted that the application height of pure cement slurry should be 3 ~ 5 mm lower than that of the grid, and it should be embedded firmly, with tight joints and the top surface on the same plane, and its straightness should be checked with lines.
3, with stone pulp surface. When plastering stone slurry, it should be stirred as required, and the surface of the stone slurry should be swept with a brush at least twice to stick the surface slurry. After the stone particles are uniform, it can be leveled and compacted with an iron trowel until the slurry is full. It should be noted here that the ripples must be leveled and the stones on the top of the grid bars should be cleaned up.
Step 4 polish. If the terrazzo floor has a large construction area, a mechanical stone mill should be used for grinding. For smaller areas or corners, a small hand-held grinder can be used for grinding. For parts that cannot be mechanically ground, they can be ground by hand.
Matters needing attention in terrazzo floor construction
1, grass-roots treatment, before construction, the grass-roots must be cleaned without oil and dust, and the grass-roots cement slurry 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.
2, brush the same level of cement mortar, and then spread 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.
3. 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.
4. The spline is unevenly exposed, which 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.
Terrazzo floor is the kind that everyone likes. When choosing this decoration method, everyone needs to know how to carry out the correct construction. The above is the construction method and matters needing attention of terrazzo floor introduced by Bian Xiao, which ends here.
