Home Improvement: How to Level the Floor Cement Mortar Leveling Construction Process

Generally speaking, the ground leveling that we talk about can be divided into two kinds: one is the leveling of the original cement mortar ground, and the second is the self-leveling cement leveling that is widely used nowadays. The meaning of both is to pass the leveling of the original ground of the building to a certain standard (the new standard for ground leveling is attached below). In the home improvement construction, the leveling of the ground cement mortar is suitable for all kinds of ground and all kinds of floor laying. It is necessary to know how to perform ground leveling and cement mortar leveling construction, so as to further improve the quality of home life. If the cement mortar leveling construction on the ground does not pay attention, it can easily cause surface pulverization, sanding, ashing, and cracking. Next, I will introduce the construction process and process for leveling cement mortar under the ground .

Teach you how to level the ground

1, self-leveling on the field

This is the most critical step in the entire leveling process. One is that the proportion of self-leveling should be just enough to ensure the strength of the ground. The ground with no strength is often the basis for the ash on the latter stage; the second is the starting position for self-leveling construction. The level of the ground must be leveled. After the flatness, it is important to start the construction from the leveling position.

The well-mixed self-leveling cement is poured directly on the ground. A word “flows” and sees the moment of falling down. This is a state of refusal or not. Do not think of self-leveling construction as too simple. When self-leveling cement is completely leveled, it is impossible. Workers are also required to use a ruler to push cement, so that cement can be pushed open.

2, roller infiltration

When this roller rolls over the cement, it will not leave any traces on it. Cement is not a pure liquid. It cannot be absolutely flat, and there will be a little unevenness in the process of pushing it, and it will be flattened by the roller.

Often the owners asked why the floor that was decorated or made by the guerrillas was good at the time. Why did the skin fall out after a few days? This issue has a very important factor in this step. The causes of these problems are the quality of the self-leveling itself, the quality of the interface agent (too much water/exact shoddy products) and the construction process. If the self-leveling is not covered with the roller when it is covered on the ground Pressing evenly can easily cause problems such as local unevenness in the ground, and small pieces of blank space in the later period, so the role of the drum is very large.

3, maintenance

Self-leveling air-drying is very fast, and generally new houses can be paved with wooden floors in three days. Because of the original ground, the old house takes about 1 week to 2 weeks. The result should be completely in accordance with the installation requirements of wood floors.

  

Ground cement mortar leveling process

Grass-roots processing → Finding elevation, line bombing → Sprinkling wetted → Plastering plaster and ribs → Stirring mortar → Bonding cement slurry layer → Laying cement mortar surface → Wood trowel troweling → Iron trowel pressing first pass → Second Press light → third pass light → curing.

The dust on the base layer was swept away, the brush and rake were brushed, and the mortar skin and ash layer were removed. The 10% fire alkali solution was used to brush off the oil on the base layer, and the lye was flushed with clean water in time.

According to the +1000mm horizontal line on the wall, measure the elevation of the surface layer and play it on the wall.

According to the horizontal line of the wall surface around the room, determine the thickness of the surface layer (not less than 20mm), then pull the horizontal line to start plastering cake (5cm * 5cm), horizontal and vertical spacing of 1.5-2.0 meters, gray cake The plane is the elevation of the ground surface. If the room is large, you must also apply markings. The mix ratio of the mortar material used for plastering the plaster cake and the standard ribs is the same as that of the mortar used to polish the floor.

  

Stir the mortar and stir it with a mixer. The color must be the same.

Before laying cement mortar, brush a layer of cement slurry (with the brush with the surface layer of mortar).

After painting the cement mortar, spread the cement mortar and spread the mortar between the ash cakes.

After the wooden trowel is flattened, it is quickly pressed with iron trowel for the first time until it is discharged. After the initial setting of the surface mortar, it was pressed with iron trowel for the second time and the surface was pressed flat and pressed. The third pass of calendering before the final setting of the cement mortar must be completed before the final setting. And always check the flatness with a 2-meter ruler.

After cement mortar ground leveling is completed 24 hours (ground calendering), sawdust or other materials covered with sprinkler water conservation, keep moist, curing time is not less than 7 days, when the compressive strength reaches 5Mpa.

Editor's summary: The above is the standard process of leveling the ground cement mortar Home renovation: teach you how to carry out the ground leveling related presentations, it seems that home decoration construction in the ground cement mortar leveling needs in accordance with certain procedures, there are provisions of the construction process can refer to, Post-construction maintenance is also indispensable. Otherwise, there will be problems that will affect the quality, but also bring trouble to the later home improvement projects.
