How about white cement without white ash? How can the cement floor not handle the ash

There are many places where it will be used in renovationWhite cement, for example, the screeching of the wall foundation, the treatment of tile trenches. But many people will find in actual operation that some white cement will fall white ash, so how to make white cement not fall ash?

Properties of white cement.

White cement is also calledWhite Portland cementIt is a kind of cement, which is a kind of high-grade cement, which is often used for architectural decoration.

The white cement has a high grade, but the hardness is not strong, the solidification time is short, and it must be mixed with other materials to exert its effect, and cannot be used aloneUse.

The reason for the ash of white cement.

1: The white cement is too dry or too thin.

That is, when the white cement is mixed, the water is too small, the powder is too dry, and it is not completely dissolved. Or the white cement is added too much water, resulting in the white cement is not solidified.

2: White cement does not match other additives.

Many people will add some other materials, such as putty powder, when using white cement.

Double flying powder, talc.

This is not much of a problem in itself, but the material formulas produced by different manufacturers are somewhat poor.

Here I will talk about the phenomenon I have encountered, the same is the interior wall putty powder, two manufacturers, one is no problem mixed with white cement, the other is not, after drying, it is all white powder when touched by hand.

3: White cement fails.

White cement is the same as cement, it is powdery, easy to absorb water and moisture, once wet, it is easy to fail, so the storage time should not be too long when buying white cement, that is, it is best to buy and use.

How to make white cement so that it will not fall powder.

1: As mentioned above, white cement belongs to high-grade cement, which solidifies quickly. Water that is too dry or too thin can cause powder to fall off, crack easily, and not have high firmness.

So in useWhen white cement is used as a decoration material, in order to alleviate its solidification time and enhance its firmness, it is not recommended to mix it with water, but it is recommended to use it801 glueWhen used together with white cement, this can not only delay the setting time of white cement, but also enhance the strength of white cement.

2: In addition to stirring with glue, for:To give full play to the maximum effect of cement, in the process of mixing white cement, add an appropriate amount of white sand, which is a special sand and is very delicate. Cement + sand is the best partner, and white cement is no exception.

Precautions for the use of white cement.

As mentioned above, white cement is mainly used for surface decoration of materials, but it is incorrect to use it as the main decoration material for walls, after all, its hardness is not strong, and it is easy to have problems.

Now the putty powder technology is very mature, as far as the decorative wall is concerned, the performance is better than white cement in all aspects, so I personally recommend that the wall decoration try to choose putty powder.

The white cement ash can only be scraped, and the appropriate putty powder can be selected to scrape the wall, and the white cement surface can not be scraped again, because this will lead to the subsequent batch scraping of the material peeling and falling off.

Conclusion. The above is my analysis of why white cement will lose powder, and I have shared a little experience on how to operate to avoid white cement. Personally, I think that white cement cannot be used as the main material for decorating the wall, so I should choose putty powder to scrape the wall as much as possible

The white ash should be properly mixed with some glue, and the wall will not fall ash. Paint the wall with white plaster first, and then apply latex paint again, which can also prevent it.

Remove some local peeling places, and then brush the primer once, ensuring that the moisture content is less than 10%, not in high humidity and low temperature environment.

Choose the best white cement, the best white cement has a good adhesion, and it will not fall off after brushing.

The method of cement floor is not ashed: first, add cement curing agent; First, clean the dust from the ground, rinse it with water, and keep the ground dry after 24 hours. It is then sprayed on the ground with a concrete sealant curing agent at low pressure.

Next, use a soft-bristled broom to distribute the material evenly and allow the ground to remain wet for 15-20 minutes. Finally, spray the porous ground several times.

When making cement floors, it is necessary to choose high-quality cement, and then it is necessary to grasp the changes in time during the manufacturing process. When calendering the concrete surface, if the time is not well grasped or calendered after final setting, it will cause the destruction of the concrete mortar layer and the cement floor sanding.

The main reason for the ash of cement floor is that the water-cement ratio is too large: the amount of water in the mixed concrete is large, which leads to water leakage on the concrete surface and reduces the strength of the concrete surface.

Improper cement varieties and small cement consumption: large brands of high-quality ordinary Portland cement should be selected, the amount of cement should be increased appropriately, and the water-cement ratio must be strictly controlled and the maintenance must be strengthened.

Excessive vibration during construction: exacerbates water leakage on the concrete surface, resulting in low concrete surface strength.

Unreasonable gradation of sand and gravel and high mud content: Unreasonable gradation of aggregate and too fine soil and sand can easily lead to sand on the ground, affecting the early hydration of cement and the coagulation of concrete.

Improper maintenance: failure to maintain in time or insufficient maintenance, exposure to the sun or strong wind leads to a large amount of water loss on the surface of the concrete, and the surface is not fully hydrated, resulting in low strength.

Other reasons: poor grasp of calendering time, work on the concrete surface before reaching a certain strength, and freezing of the concrete surface under low temperature.

Methods of curing cement floors.

Spray or paint a layer of film-forming substance on the surface of the cured concrete to isolate the concrete surface from the air to prevent the evaporation of water inside the concrete, maintain the internal humidity of the concrete, and achieve the effect of long-term curing. It is one of many maintenance methods, and for parts such as the façade of concrete structures, or some parts that are not large in size but complex in structure, and cannot be cured by other methods, the curing agent has an irreplaceable role.

Dear, I'm glad to answer for you, what to do if the cement floor falls with big white ash Answer: Use a small shovel to shovel off the big lime. Then dilute the small pieces of lime with water and wipe it clean, the strength of the lime is not high, it can be removed, generally with an iron trowel, wire brush, sandpaper, shovel brush can be removed.

If it is a wooden floor, it can only be moistened with a cotton cloth and then wiped to prevent it from being worn out. Toothpaste. First of all, squeeze the appropriate amount of toothpaste on the brush, determine the high dosage of toothpaste according to the size of the cement ash, and then brush directly, and soon you will find that the cement ash on the floor is removed.

Card. To remove cement ash, we can also use a variety of membership cards that we usually come into contact with, and scratch the card against the place with cement ash, which can not only be scraped very clean and fast, and finally wiped it with a rag.

Summary. It is okay to do white ash on the cement floor and not to do white ash, depending on the specific situation and use needs. Making white ash can make the ground smooth and beautiful, prevent water stains and dust, and increase the service life of the ground, but it is relatively easy to produce cracks.

It will be more economical not to do white ash, but it needs to be sanded and maintained, otherwise the ground will have problems such as chipping and cracking. Therefore, please choose whether to do white ash according to the actual needs.

Is it okay to do the ground without ash and pour cement directly?

Making white ash can make the ground smooth and beautiful, prevent water stains and dust, and increase the service life of the ground, but it is easier to produce cracks. It will be more economical to dismantle and do not do white ash, but it needs to be polished and maintained, otherwise the ground will have chips, cracks and other problems.

Therefore, please choose whether to do white ash according to the actual needs.

What I asked was whether the cement pavement should be tamped before the cement pavement was made.

Before the construction of cement pavement, the foundation should first be compacted. The bearing capacity and stability of the foundation can be increased by lime soil compaction, which can extend the service life of the cement pavement while ensuring that the cement pavement is smooth and firm. In addition, it should also be known that the ground should be cleaned, leveled and moistened before the cement pavement construction is carried out to ensure the bonding effect and quality of the cement pavement.

How to plaster the earthen wall without plastering the white lime without falling ash: the white lime will not fall off the ash if the wall is plastered with macro. When using white ash to paint the wall, you can properly mix some glue in the white ash, so that the white ash after mixing the glue is used to paint the wall, and the overall effect is very good, and there will be no ash.

It can also be prevented by painting the walls with white plaster, and then applying latex paint. White ash slows down the ash on the shed wall, and can beautify the wall and make the wall more uniform. Brush the white ash wall first, and then brush the industrial glue again, which can play the role of sealing the white ash and prevent the surface from falling ash.

Cement floor, pitting and losing skin, ash, sand, the ground hardness is low, not wear-resistant, and dust and sand particles can not be swept clean.

Treatment: Use cement sealing curing agent.

Sweep the ground clean of dust and sand, you can also rinse with water or clean it with a damp mop, the ground can be wet but there is no open water.

Pour the material on the ground to fully penetrate into the ground, and then spread it out with a roller. According to the severity of the dust and sand on the ground of the inspection, 2-3 stools can be painted, with an interval of about 30 minutes.

The ground after the nuclear cherry tree can be walked after 24 hours, and it can be opened to traffic after 48 hours, and it can be used both indoors and outdoors.

Hello dear, glad to answer for you. White cement is a very pure cement that can take on a brighter white color after hardening. If you need to mix white cement into earthy gray, you need to add the right amount of gray pigment to its mixing process.

Common gray pigments include natural iron oxide pigments, chromate pigments and black gold pigments, all of which can make white cement into a gray with no coarse holes or the same shade. In the preparation process, it is necessary to gradually add the pigment and stir well according to the desired rock of the mixing ratio until the desired earth gray color is reached. It should be noted that if too much or uneven pigment is added, it will affect the accurate modulation of color, so the amount of pigment added needs to be well controlled to avoid color difference.

1. Grassroots treatment. Remove the dust and dirt of the base layer, fill the silver grip flat holes, and should have a certain roughness (chiseling), sprinkle water to moisten, and nail a layer of metal mesh at the junction of different structural bases or fighting layers to avoid cracks, and the lap width of the metal reinforcing mesh and each matrix should not be less than l00mm. The brick base should be fully compacted before plastering.

2. When indoor plastering, it should be carried out after the installation of water and gas pipelines, and the wall holes and floor holes through the pipelines must be filled and compacted before plastering. The sunny corners of indoor walls, columns and door openings should be protected with 1:2 cement mortar, the height of which should not be less than 2m, and the height of each side should not be less than 50mm.

Before the construction of the exterior wall plastering project, the steel and wood door and window frames and balconies should be installed.

3. Railings and embedded iron parts, etc., and the construction holes on the wall are plugged and compacted.

4. Bottom plastering. The thickness of the bottom plastering is 5-9mm, and the function is to make the plastering layer firmly combined with the base layer and leveling.

5. Middle layer. After the bottom layer is dried, the main role is leveling, the thickness is 5-12mm, the standard bar should be made, and the middle layer should be scratched out before condensation, so as to combine with the surface layer.

6. a surface layer. The thickness of the surface layer should be 2-5mrn, and the main function is decoration, which requires a smooth and smooth surface without cracks. The total thickness of the plastering shirt is generally not more than 35mm, and measures should be strengthened when it is exceeded.

7. Cement. Plastering is commonly used ordinary Portland cement, pozzolana Portland cement, slag Portland cement and white cement. The cement should not be agglomerated by moisture, and the plastering project should re-inspect the setting time and stability of the cement.

8. Lime. The quicklime should not be less than 15 days when it is cured at room temperature, the frozen and weathered lime paste shall not be used, and the curing period of the finely ground ordinary lime powder used for the cover should not be less than 3 days.

9. Sand. Commonly used medium sand or mixed sand of medium sand and coarse sand, the impurity content does not exceed 3, should be sieved.

The former leveling uses ordinary cement mortar, leveling has large defects, one is that the flatness control can not achieve the greatest accuracy, and the leveling thickness is high, and the second is that the construction process is easy to increase the ground of the house due to the technical problems of the construction party.

The latter is self-leveling ground leveling. This is a new leveling technology, which began to be in the domestic construction floor industry in 2005. It uses high polymerization self-leveling cement for ground treatment, which has many advantages, the thinnest ground can be leveled at 3 mm, the thickness is controllable, the ground strength is high, and the flatness is much higher than that of cement mortar leveling.

It can be used for home improvement floor leveling. Ground treatment of various stadiums, hotels, office spaces, precision electronics workshops, etc. The ground leveling in front of the home decoration paving wooden floor is also suitable for self-leveling ground leveling.

The self-leveling leveling ** and cement mortar leveling ** of the general regular ground company are basically the same. Choosing self-leveling is becoming more and more cost-effective.

Harm. For home improvement. Doing ground leveling is generally because you want to install wooden flooring, or you have to do epoxy flooring and find that the ground is uneven, how to distinguish it?

We usually use a two-meter ruler to take carpet measurements. That is, at least the same position is measured in the direction of the crossing, if there is a gap of more than 3 mm or even 5 mm under the ruler. This indicates that the ground is uneven.

It has exceeded the requirements for the paving of wooden floors. In many cases, some friends will think that 5 mm does not matter much. The construction commitment letter of the flooring company was signed and the floor was forcibly installed, which resulted in an empty sound on the floor.

The locks are broken and the corners of the walls are dusty. The floor feels like a seesaw, and at this time there is a big loss. And due to the forced construction of the flooring, the company cannot give you any compensation.

So if it is to install the floor. Whether it is solid wood, laminated or laminated flooring, the pre-treatment of the floor is very important.
