What tools are used for sand repair on the cement floor?

Tools: mortar mixer or manual mixing tools, high-pressure water washing equipment, bottom cleaning tools, sponges or mops (for absorbing excess water), more than two iron mixing buckets, and several trowels.

Materials: Of course, it is the repair material of Lumei, note: it cannot be constructed in rainy days.

There are many reasons for the sand on the surface of concrete, and the main reasons are.

1.Improper cement varieties and small cement dosages

2.The water-cement ratio is too large: that is, 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.

3.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.

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

5.Improper maintenance:

6.The calendering time is not well mastered, the concrete surface does not reach a certain strength, and the concrete surface is frozen at low temperature.

When pouring the cement floor, if the process is not correct or the selection of materials is not properly discussed, it may lead to the problem of sand on the cement floor in the later stage. After a long time, this phenomenon will become more and more serious, and many people will directly find the master to deal with it, in fact, there is no need to be so troublesome, teach you a few simple methods to be able to deal with it quickly.

1. Remediation method for sand on cement floor.

1. If the area is smaller, we can stir some pure cement mortar, apply it to the sanding part, and wait until it is dry to be able to use normally. However, relatively speaking, there may be some color differences, but it is no problem to use.

2. If the area is relatively large, you need to choose the yarn treatment agent on the ground, mix and dilute it with water according to a certain proportion of requirements, and then apply it to other parts, soak it for 2 or 3 hours, and then wipe the residual treatment agent to meet the requirements. At the same time, if there are conditions, the ground can also be cured and polished, which can make the ground more beautiful, and the repair effect is very good.

Second, why does the cement floor have sand?

We need to understand why the ground is sandy, so that we can effectively avoid such problems from happening again next time.

1. When deploying cement mortar, the ratio of cement and lime must be controlled, and it cannot be changed at will, otherwise too much or too little water will lead to problems. In addition, do not use fine sand, because its texture is relatively fine, and the strength does not meet the requirements.

2. During construction, we must strictly follow the steps, such as cleaning the ground in the early stage, if the ground is cracked or uneven, there will be more problems in the later stage. At the same time, it is also necessary to carry out compaction, otherwise it will affect the effect of the ground.

3. It is also necessary to carry out reasonable maintenance, and after the concrete is laid, it is necessary to water, and the ground must always be kept in a moist state.

Summary: If there is a problem of sand on the cement floor, don't worry, according to the specific problem, whether it is a large area or a small area, it can be effectively solved. You don't need to ask for a master, you can solve it at home.

The cement floor at home is sanded and repaired with concrete sealing and curing agent.

The emergence of wall sand hardening agent solves the problem of wall plastering mortar sanding, sand turning, sand removal, sand dropping, and sand return, it is a permeable material, which can penetrate into the base layer of mortar, harden the base layer, and the depth of penetration is related to the number of times of painting.

General scraping putty, the part of the wallpaper can be brushed through, the part of the tile can be brushed twice, Z2 concrete hardener has been more than ten years of market practice, and is deeply recognized by the industry.

The traditional wall sanding repair method is as follows:

There are only three ways: one is to shovel and redo, which is effective, but the repair cost is very high.

The second is to use a certain 7, 8 such glue, interface agent and other materials to deal with, this kind of used should know, the symptom is not the root cause, because these are the surface film-forming materials, will not penetrate into the base layer of the high-burning surface, scrape on the greasy virtual child and paste the wallpaper on the tile after the hollow drum problem will slowly show.

The third is to use cement slurry cover, which is actually similar to the second kind, although it can seal the surface of the desanding in a short time, but there is no permeability, so it cannot solve the fundamental problem. <>

The cement floor at home is sandy, and the specific repair steps are as follows:

1.Clean the cement floor: First of all, you need to use a brush to clean up the debris and dust on the ground, and thoroughly clean the sanded part with a wire brush or steel brush to ensure that the surface is smooth and dry.

2.Add binders: After cleaning, you can use professional cement floor repair materials and add some special binders. Apply the binder to the sand to make it firmly connected to the concrete underneath.

3.Fill the cracks in the ground: If there are large cracks in the ground, you can use the caulking material to fill the gaps, and the caulking material should be made of materials similar to the color of the original cement floor to restore the smoothness.

4.Grinding and polishing: After waiting for the ground repair material to dry, you can use a sanding machine or hand sanding, and then polish it to make the ground smooth and flat, and look like new.

It should be noted that if there is relatively large damage to the ground of Hengqiaoguo or accompanied by serious cracks, cracks and other problems, it is best to ask a professional decoration company to help repair it to ensure the quality and effect of repair.

The cement floor is more wear-resistant, the cement floor is also relatively simple and convenient, the rural yard and the ground on the first floor can be used with cement floor, which is more convenient to clean, but the cement floor is prone to the problem of sanding, which will affect the appearance and daily life, and should be repaired in time. How to prevent sand on cement floors? Follow me to find out!

What material is used to repair the sand on the cement floor at home.

1. According to the degree of sanding of the cement floor, different treatment methods can be selected. If the degree of sand is relatively slight and the area of sand is not large, you can buy some cement slurry by yourself, stir it evenly, and apply it to the sanding place on the cement floor. After the cement is dry, it will no longer affect daily life, but the color of the ground may look uneven, but this will not affect our daily use, so if there is no special pursuit of appearance, you can use this method.

2. If the sand area is not particularly large, but it is not small and is at a medium level, then it is not very convenient to treat it with cement slurry. We can buy some ground treatment agent, mix the ground treatment agent and water in a certain proportion, stir well, and then apply the mixture to the sanding position, within three hours after application, it needs to be kept moist, and after air drying, it can be used normally.

3. If the area of cement floor sand is relatively large, it is necessary to use repair mortar for repair. Before applying the repair sand slurry, it is necessary to apply the interface agent to the sanding area in advance. After applying the interface agent and repair mortar, calendering and polishing can be carried out if possible, which will make the floor more shiny.

How to prevent sand on cement floors?

1. In order to prevent sand on the cement floor, before the initial laying of the cement floor, do not put too much cement lime when preparing the cement slurry, so as to prevent the loss of moisture on the surface of the cement floor in the future, resulting in sanding.

2. When we choose cement raw materials, we need to carefully screen suitable raw materials, among them, the gravel in the cement should not be too fine, and after the cement is paved, we also need to pay attention to the later maintenance, so as to reduce the probability of sand on the cement floor.

What materials are used to repair the sand on the cement floor at home? How to prevent sand on cement floors? The above is the relevant content I introduced, you can use it as a reference, cement floor sand should be dealt with in time to avoid getting more and more serious, but also to choose the best cement sand.

The cement sanding ground repair method is as follows:

1. If the area of sand on the ground is relatively small, you can make a little cement mortar, but you must use pure cement slurry and wipe it directly on the sand place. However, there may be some color differences, but the area is not particularly large and cannot be seen.

2. If the area of sand is slightly larger, you need to use a professional ground treatment agent, mix it with water evenly according to the instructions, and spray it on the place where the sand is raised. In the later stage, it is necessary to continue watering and moistening for three hours, and then wipe the excess treatment agent around it.

3. If the area of sand is relatively large, it is necessary to spray the interface agent on the ground first, wait until the effective penetration reaches an hour, and then apply it directly to the ground with repair mortar, and it also needs to be calendered. If conditions permit, it can also be cured and polished on the ground, which can achieve a certain gloss, and can also solve the problem of sanding on the ground, which is more suitable for large-area operation.

Why does the cement floor have the problem of sanding?

1. When preparing cement mortar in the early stage, the proportion of cement lime is too large, which will lead to a lot of water inside, so that there will be water loss on the surface, and the strength of the surface will gradually decrease. After the cement floor is solidified, there will be sand on the ground, which is mainly caused by mistakes during construction.

2. There is another reason for the sand on the cement floor, that is, the level of sand and gravel prepared is not enough, and the mud content in the cement is relatively high.

3. There is also a direct relationship between sand and improper maintenance in the later stage, because the maintenance work is also very important, it must be timely and sufficient.

Indoor cement floor sand remedy pro! Hello, very bright blind posture happy to answer for you<> pro-cement floor sand repair method is: choose the general repair mortar method, make a little pure cement slurry, and then wipe it in the sand area.

During the curing process, the ground will become very bright, and the problem of sanding on the cement floor will be solved. You can also use the method of grinding the base surface, use a professional grinder to polish the base surface, clean up the surface slurry and dust, and open the gap of the original ground, so that the concrete sealing curing agent can fully penetrate into it, and the repair can be completed. Extended informationThe best material for cement floor sand repair material is the curing agent, first of all, the ground is cleaned and cleaned, the dust and impurities on the ground are reduced, the curing agent is mixed with water in proportion, and it can be mixed according to the range of sand, and after stirring evenly, it will be poured into various positions of the sand, and try to separate some, because the water is fluid, and then sweep it away with a broom.

Cement floor sand solution:The easiest way to deal with it is to use penetrant, the penetration agent is also relatively cheap, you can buy penetrant directly on the Internet, but the smell of penetrant is very large, and it will emit an unpleasant smell if you use it more.

If the cement floor is sanded, you can use the BW201 floor penetrant of Bangwei building materials to repair, the ** per square meter is about 5 yuan, and the repair method is also very simple, you only need to spray the penetrant on the cement floor, and wait until it is dry.

However, when using floor penetrant, you must remember to wear a mask, the smell of floor penetrant is very unpleasant, and it also has a certain harm to the human body, so you must remember to open the window for ventilation in the later stage, and it is best not to walk around within half a month.

Cement floor sand repair method:Clean the sandy floor, no floating ash, keep it dry (moisture can be allowed, but there must be no open water); Cracks and defects should be repaired with high-strength repair materials, and then hardened with concrete hardeners.

After at least 48 hours of construction, 2 materials are used to directly paint the ground after hardening, and it can be used once and again, which should be uniform and full, without maintenance, and can be used normally after 7 days.

Causes of sanding on cement floors:1.When concrete and mortar are mixed, excessive water is added, or the mixing is uneven, and the mortar is separated and reacted to the surface of the sand and peeling.

2.The number of calendering on the surface is not enough, the pressure is not real, and there is water separation and sanding.

3.The calendering time is not well controlled, or the calendering after the final setting, the surface layer of the mortar is damaged and the sand rises.

4.The strength grade of the cement used is too low, resulting in the failure to meet the required strength grade.

5.The gradation of sand and gravel aggregate used is too fine, resulting in the required strength grade not being achieved.
