Knowledge of concrete flooring!

The decoration circle has the same mysterious existence as the fashion circle of outdated clothing assembly trends, such as concrete floors. A few years ago, the cement floor was still a floor material that had to be selected when the budget for building a house was too low, but now it has become the decoration industry net red.

Many well-known architects use concrete floors at home, which looks very artistic and quality. Therefore, cement has become one of the essential elements in Nordic style, minimalist style, industrial style, and even Japanese style decoration. .

Look at the concrete floor with a chic wooden furniture, a proper classic Japanese style, it is not too much to call it “wild floor”. Therefore, the status of the cement floor is not what it used to be. It depends not only on the aesthetic changes of the decoration, but also on the many advantages of the cement floor itself:

High construction efficiency

Cement is still the original cement, but the process is very different. The traditional artificially made concrete floor requires a little bit of manual filling and equalizing processes. For example, it takes about half a day to make the bathroom floor, and the same area can be completed in less than half an hour using cement self-leveling land.

Cement self-levels the ground. This process is to add free water to the cement to form a free-flowing floor coating. When poured onto the ground, it will quickly fill the ground according to the surface level of the ground. The thickness of the self-leveling layer of cement in the home is 3 ~ 5mm is enough, so the hardened floor material can be used after walking for 24 hours. Can greatly shorten the construction period, and use less material, high strength, good wear resistance.

Cheaper than other floor materials

The installation of ceramic tiles and wooden floors can cost hundreds or thousands each time, and the cost of concrete floors is much lower. For example, the overall price of construction in Shanghai is generally RMB 40 ~ 120 / ㎡. The larger the area, the more the cost, the smaller and more expensive the cement floor. After all, the construction cost is low. The construction of a small area may be “not worth doing” for the construction team.

What is really small but want to do cement self-leveling? Many families in Europe, where the cost of learning workers is high, get their own food and clothing.

Then, when choosing cement, you should understand the price difference of different cements in the strength of cement materials.

One price is one share, and the high-strength cement is ready for the next decoration after it is completely dry, and many brands have different colors to choose from.

Generally, low-strength self-leveling cement has only one color, and there are second and even third links, because after drying, it looks like the effect of a rough room. The surface is not smooth and easy to ash, and it also absorbs water.

The hardness and abrasion resistance are not enough, and the strengthening treatment of the uppermost facing layer is needed. Such as painting, using seal curing agent, or corundum wear-resistant aggregate. These not only increase construction time, but also increase costs.

In the back, polishing or wax polishing is needed. Not to mention that these materials can not be selected for inferior quality. If there are harmful substances, they are worth more.

Stable, moisture-proof and environmentally friendly

Properly treated cement can be used in the kitchen bathroom:

Tiles need beautiful seams, and boards need to be selected. There may be some formaldehyde, odor, and expansion and contraction, and the concrete floor need not worry at all. But the cement self-leveling construction process still needs attention:

1.Remember to do wall protection

Before cement self-leveling construction, the boundary between the surrounding and the wall must be separated. Separate the self-leveling from the wall and release the stress. Generally, a 3mm thick foam strip is attached to make the interval. Adhesive tape should be applied to the wall near the ground to prevent cement from splashing on the white wall.

2. Basic surface pretreatment

The quality of the house depends on the firmness of the foundation, and the self-leveling of the cement is the same. You cannot underestimate the treatment of the base. If there is a crack in this layer, the surface layer will also crack.

If cracks really appear, they must be repaired in time. If small cracks are filled with epoxy resin, if there are more cracks in the base layer, a layer of anti-cracking grid cloth must be laid for reinforcement and covered with repair mortar.

Finally, it can be covered with a layer of quartz sand to improve adhesion.

3. Precisely control the cement mixing ratio

The ratio of cement to moisture cannot be more or less, and must be precisely controlled in strict accordance with the instructions. Otherwise, the ideal cement surface cannot be achieved. For example, too little moisture will reduce fluidity, fail to meet the requirements of self-leveling, and cause problems such as shrinkage and cracking.

To grasp the specific amount of water, you can use a marked measuring bucket to add water.

4. Grasp the tilt

The inclination of the base layer affects the state of self-leveling. The domestic standard is within 3m of the ruler, and the drop should preferably not exceed 4mm. If the ground is more inclined, calibrate from the lowest point:

5. Pay attention to humidity and temperature during construction

The specific base surface has a moisture content of less than 6%, air humidity of less than 60%, and an ambient temperature of 10 to 25 degrees is the best. If there are faucets or water pipes in the self-leveling area, be sure to protect them in advance, otherwise you may have to knock them all out and redo them.

6. Cement should be defoamed

The self-leveling cement mixed with powder and water will generate bubbles to some extent. The defoaming measures include: standing still after mixing, stepping on the bubbles with spiked shoes during the construction process, and using a defoaming roller. The rollers will leave marks. It is recommended to use imported stainless steel needles for defoaming, the effect will be much better.

7. Note the border seams

The gaps between the self-leveling cement and other floors or walls and junctions can be flat batten, pass stone, high and low buckle, and inlaid metal seam strips. Among them, the metal seam strips have a better final effect and are more seamless.

8. Modification is not monotonous

In addition to the decorative layer can be considered to do retro color paint, adding brass inlaid patterns are interesting, not monotonous.

9. Regular waxing maintenance

Many advertisements say that “cement self-leveling” is a maintenance-free floor. In fact, if you want a floor with a long service life, regular maintenance is essential. Waxing and polishing the cement floor every 3-9 months can not only maintain the gloss of the floor, but also avoid cracks. In addition, it is usually best to wipe the floor with a neutral cleaning solution.

Frequent walking areas such as doorways, baby play areas, living room corridors, and carpet cushions can reduce wear and tears and look tender.

10. Clever repair of cracks

Once cracks appear on the cement floor, in addition to using ordinary joint fillers, golden joints are also a good choice. After repairing, there is a unique aesthetic feeling.
