The status of cement floor is not what it used to be
.
It not only depends on the change of decoration aesthetics, but also has many advantages of cement floor: high construction efficiency, cement or original cement, but the technology is very different
.
The traditional manual cement floor, because it needs manual filling, leveling and other processes, such as toilet floor takes about half a day, and the same area can be completed in less than half an hour
.
Cement self leveling floor, the “self leveling” process is to add water with cement to form a free flowing floor coating, pour it to the ground, it will quickly fill the ground according to the surface smoothness of the ground, the thickness of this layer of cement self leveling at home is 3 ~ 5mm, so the self leveling cement surface is generally hardened floor material that can be used after 24 hours
.
It can greatly shorten the construction period with less materials, high strength and good wear resistance
.
Stable, moisture-proof and environment-friendly, tiling needs beautiful joints, planing needs to choose good materials, and there may be odor, expansion and contraction changes, etc., while the cement floor does not need to worry at all
.
But the construction process of cement self leveling still needs attention: 1
.
Remember to do wall protection, before cement self leveling construction, we should first separate the surrounding boundary from the wall
.
Let the self leveling and the wall separate, release the stress, usually is the 3mm thick foam strip to make the interval
.
The wall close to the ground should also be glued with adhesive tape to prevent the cement from splashing on the white wall
.

.
The quality of the base surface pretreatment house first depends on the firmness of the foundation, and the cement self leveling is also the same
.
We can’t underestimate the base treatment
.
If there are cracks in this layer, the surface layer will also crack
.
If cracks do appear, they should be repaired in time
.
Small cracks should be filled with epoxy resin
.
If there are many cracks in the base course, a layer of anti crack mesh cloth should be laid to reinforce and then covered with repair mortar
.
Finally, a layer of quartz sand can be covered to improve the adhesion
.

.
Accurately control the cement mixing proportion, the proportion of cement and moisture can not be more or less, must be strictly in accordance with the instructions to accurately control
.
Otherwise, the ideal cement surface can not be achieved, such as too little water will reduce the fluidity, can not meet the requirements of self leveling, and will lead to shrinkage cracking and other problems
.
The specific amount of water can be mixed with a marked bucket
.
4
.
Grasp the inclination of the gradient base to affect the state of self leveling
.
The domestic standard is within 3M guiding rule, and the drop should not exceed 4mm
.
If the ground tilt is large, calibrate from the lowest point
.
5
.
Pay attention to the construction humidity and temperature
.
The moisture content of the base surface is less than 6%, the air humidity is less than 60%, and the ambient temperature is 10 ~ 25 ℃
.
If there are faucets or water pipes in the self leveling area, the protection work must be done in advance, otherwise it may have to be knocked off and redone
.

.
The cement should be mixed with defoaming powder and water
.
The self leveling cement mixed with defoaming powder and water will produce bubbles
.
The defoaming measures include: standing after mixing, wearing nail shoes to break bubbles during construction, and using defoaming roller
.
The rolling drum will leave traces
.
It is suggested to use imported stainless steel needle defoamer roll, the effect will be much better
.
7
.
Pay attention to the gap between the self leveling cement and other floor or wall joints at the boundary joint
.
Flat strip, door stone, high and low buckle, inlaid metal joint strip and other methods can be used, among which the metal joint strip has better effect and is more integrated
.
8
.
The decoration is not monotonous
.
In addition to the retro color paint, the pattern created by brass inlay is interesting and not monotonous
.
9
.
Regular waxing and maintenance
.
Many advertisements say that “cement self leveling” is maintenance free floor
.
In fact, it is not
.
If you want to have a long service life, regular maintenance is indispensable
.
Waxing and polishing the cement floor every 3-9 months can not only keep the luster of the floor, but also avoid cracks
.
In addition, it’s better to wipe the floor with neutral detergent
.
Walking frequently in areas such as the door, baby play area, living room corridor, carpet cushion can reduce wear and tear, looking at the warmth
.
10
.
Repair cracks skillfully
.
Once cracks appear on the cement floor, in addition to using ordinary joint sealer, golden joint sealer is also a good choice
.
After repair, it has a unique aesthetic feeling
