What should I do if the cement floor is old and gray?

Reprocess the ground using a screed.

In other words, if we plan to lay a wooden floor and the floor needs to be releveled, then we should not deal with it separately and use a new screed. The conventional method is to smear a layer of cement mortar on the ground, and the strength of the cement mortar is higher, that is to say, the cement content is larger. If the thickness is thicker, you can beat a layer of concrete, and then use a plate vibrator to level the ground.

After that we lay a wooden floor on top and there was no problem.

Causes of ash on cement floor: The water-cement ratio of cement mortar is too large; improper construction process; improper maintenance; Concrete construction at low temperatures; Unqualified raw materials, etc.

Workaround:

Sprinkle water evenly on the floor when cleaning, so that there is no dust when cleaning.

Brush the ground paint, if you don't want to do too much treatment on the ground, you can brush the paint, economical and easy to operate, choose your own color to make it beautiful and generous.

Carpet the whole and choose practical. It's easy and trouble-free, and you can also choose different patterns to decorate.

Foam floor mat, easy to use, environmentally friendly materials, colorful styles, with color sense and imagination space, is the best choice for children to play and play.

There is also the purchase of concrete reinforcing agent for painting, you can paint 2-3 times, the cost is 10 yuan square look, compared to the outside construction team is very cheap.

1. Clean the ground: First of all, we have to use a brush to remove the dust, and then rinse the ground with clean water; Then find the gap or pit, make putty with cement mixed with glue, and then carry out the repair work, and the repair effect can reach the same level.

2. Paint the ground with glue: stir the glue and water in the ratio of 1:2 leakage, and then paint the ground.

3. Glue cement putty should be scraped in layers: in order to achieve a good effect, it is recommended to scrape 3-4 times, and each time each layer of scraping can be controlled at the thickness. One thing to note here is that the proportion of putty to be scraped and coated with the bottom layer should be controlled at:

Cement: 108 Glue: Water = 1::.

As long as you stir evenly according to this ratio, you can work on the ground, and the bottom putty is recommended to be scraped 1-2 times. The proportion of surface putty should be controlled at 1::, and it is recommended to scrape 2-3 times.

Because, when the room temperature is lower than 10, the glue is very easy to freeze and cannot be proportioned. In order for the glue to melt in its natural state, temperature control is crucial. Sell the search.

The easiest way to deal with cement floor ash is to use concrete sealing and curing agent. Concrete sealant can be rolled directly onto concrete floors. Concrete sealant curing agents are inexpensive and easy to use.

When using concrete sealing curing agent, it is necessary to grasp the order of construction, so as not to affect the final effect. The steps are as follows: Which Shankai.

1. Spray the concrete sealing curing agent on the ground at low pressure, and then use a microfiber mop or soft bristle broom to distribute the material evenly, and avoid using accumulated materials.

2. Let the ground remain wet for 15-20 minutes, and then spray again on the porous ground and the ground in the area where the material has been absorbed.

3. When the material is hardened, do not use a microfiber mop or soft hair broom.

Causes of ash on the cement floor].

1. Cement is made of concrete, mortar, water, etc. stirring, mixing and drying, but when making cement floor, if excessive water is added, it will cause the water-cement ratio to be too large, and then cause the cement floor to be ashed, if it is serious, it will also cause the phenomenon of cement floor sanding.

2. When making Li called the cement floor, it is necessary to calender the concrete surface many times, if you do not do this, it will cause the cement floor surface to be not strong enough, and it is easy to ash and sand.

3. When carrying out any steps, it is necessary to grasp the time change, for example, when calendering the concrete surface, we must pay attention to the change of time, if the time is not well mastered, or the calendering after the final setting, the concrete mortar layer will be damaged, causing the cement floor to be ashed, and the cement floor will be sanded.

4. There is also the low quality of cement, which affects the quality of cement floor, resulting in ash and sand, so when making cement floor, only slow high-quality and high-quality cement must be used.

In fact, the reason why the cement floor is dusted is that it is not properly made and maintained, so it will be ashed. In order to avoid the phenomenon of ash on the cement floor, in addition to meeting the specifications when making, regular maintenance should also be carried out.

1. First of all, we can sprinkle some water on the cement floor every day, so that the dust cannot fly into the air, but if it rains, the ground is not easy to dry after sprinkling, and the room will become very humid.

2. Painting a layer of paint on the cement floor can also effectively prevent ashing, but because many paints contain formaldehyde, many friends are not at ease, so they should choose safe and pollution-free paint before purchasing, and you can wait for a period of time after brushing before moving in.

3. We can also lay carpets on the cement floor to isolate dust, which can not only prevent dust, but also play a decorative role.

The above is what I share with you to solve the situation of cement floor ashing, I hope it will be helpful to you. Finches.
