How to deal with the sand on the residential cement floor? What materials to use economically.

1): Apply cement floor curing agent. Cement floor curing agents include some water-based repellents and oil-based repellents. It is mainly to prevent the ground from dusting and increase the strength of the ground.

2): Construction liquid hardener. Liquid hardener, also known as concrete sealing and curing agent, is a water-based preparation for treating ash and sand on cement floors.

By brushing on the cement floor or the cement floor after mechanical grinding, it can seal the pores of the ground, increase the strength and wear resistance of the ground, and prevent ash and sand. At the same time, the gloss like marble will increase the decorative effect of the floor, and the ground will become brighter and brighter the more you use, and it can be guaranteed for more than 20 years. According to the different construction technology, it can be divided into dark light floor, matte floor, semi-light floor, bright ground and mirror floor.

3): Paint the floor. Floor paints generally include epoxy floor paints and polyurethane floor paints.

It is mainly used for the coating construction of cement floor, which can solve the sand and ash of the ground and increase the cleanliness and aesthetics of the ground. According to the construction process and the type of floor coating, it is divided into thin floor paint, mortar flat floor paint, self-leveling floor paint, etc.

4): The use of concrete sealing curing agent, which changes the loose structure of the concrete floor through a series of complex chemical reactions, focuses on improving the hardness and tightness of the concrete pavement itself, and can meet the requirements of indoor and outdoor concrete ground use.

The construction process of cement floor sand treatment is as follows: 1Base Treatment:

Clean and sweep the cement floor with ash and sand to keep the ground clean and dry; 2.Blanking: Brush the concrete sealing curing agent on the ground, keep the penetration for 4 hours, keep the ground moist during the period, do not let it dry, and drag the material back and forth with the spearhead to let the material fully penetrate; 3.

Grinding and polishing: grinding and polishing the ground, and using grinding discs to a certain number according to the requirements of the contract, so that the ground is flat, smooth, wear-resistant and beautiful.

Cement is a very low-cost method of decorating floors. It has a wide range of applications and a simple structure. Sand on the cement flooris a common problem.

Because there is sand will affect the construction on the ground, the proportion of cement, if not solved in time, it will affect the subsequent work, and I will introduce how to solve it belowSand on the cement floorand how to effectively prevent itSand on the cement floor

1.Curing process: You can't let the sand get completely wet if you spray the sand from the bottom, there is an effect to protect the spray and make all the dry excessive disposal of the absorbent in the floor, after two time effects, the fourth in a row.

2.Abrasive handling can be enhanced by one day of processing: a penetrating curing agent is sprayed from the bottom, increasing compressive strength, hardness and density.

1.Strictly adjust the water-cement ratio.

If the failure of the cement affects the hardness of the cement, the lower bottom surface hardness is to prevent the construction personnel from strictly source such a situation, because they do not wear rough sand at the bottom of the box and often control the water-cement ratio should occur.

2.Expired cement cannot be used.

If the use of old cement produces disadvantages, it is easy to achieve the hardness of the ground on the sandy bottom, if the wet cement, the sand usually occurs in this case for a short life of use.

3.The surface should be avoided with fine sand as much as possible.

Otherwise, after a period of time on the underside, this situation appears on the beach, there is a lot of pressure and friction, so try not to use sand or rough because of the surface of fine sand, it is recommended that you use sand at least the surface.

4.Ensure adequate maintenance time.

Ground maintenance usually takes more than 7 days. Without sufficient curing time, surface moisture will continue to evaporate, resulting in damage to the surface layer and increasing the likelihood of sanding.

Cement floor sand treatment method.

1. If the sand area is relatively small, it is recommended to stir some pure cement mortar, evenly coat it in the sand area, and use it normally after drying. Although there are some color differences, there is no problem with using them.

2. If the sand area is relatively large, it is necessary to choose a professional sand treatment agent, mix and dilute it with water according to the normal proportion requirements, and then apply it to the sand area.

After waiting for 2-3 hours, wipe off the residual treatment agent to meet the requirements. If possible, it is recommended to do the curing and polishing procedures for the ground to make the repair effect of the ground more beautiful.

What causes the cement floor to sand?

1. The main component of cement floor is cement and mortar concrete. When mixing materials, too much water is used, and no vibration treatment is carried out during construction, so it is easy to cause the cement to sink and the sand and gravel to float after the concrete is poured. If the sand and gravel float too much, the phenomenon of sand will appear after drying.

2. In addition, when mixing cement mortar, the ratio of each material is not strictly stirred according to the requirements, and the mixing of each material is uneven. In addition, if the level of sand and gravel used is not enough to meet the requirements of the ground, it is easy for the sand and gravel to float, and the phenomenon of sand will appear.

If the grade of sand and gravel is not enough, it is easy to have sand and gravel that cannot be truly integrated with other materials, and naturally the problem of material separation and sand will occur after drying.

3. After the cement floor is poured, it is not well maintained, and it is easy to have the problem of sanding. Generally, after the construction of the cement floor is completed, a layer of curing film needs to be added, and after a period of time, it is necessary to carry out matte treatment. If these steps are not in place, it will be easy to sand the phenomenon.

After the delivery of the rough house, the ground is mostly concrete cement floor, some owners will find that the cement floor has the problem of sand during the house inspection, and the ground sand will affect the ground decoration, so we need to deal with the ground sand in a timely manner, so how to deal with the cement floor sand as a spring? Next, I will briefly introduce it to you.

1. If the cement floor has a small range of sand and less floating dust, you can first clean up the floating dust on the surface, and then paint pure cement slurry at the sanding place, and the cement should choose Portland cement. If the cement sand is large and serious, we need to re-construct, we first shovel off the ground of the sand, and then re-construct in strict accordance with the construction technology standards.

2. If the scope of sand on the cement floor is large but not very serious, we can use relevant ground treatment agents, such as painting floor paint, coating liquid hardener, painting cement floor curing and shouting agent, etc. Among them, the adhesion of epoxy floor paint and cement base layer is strong, which is suitable for the sealing primer of concrete structure, which can improve the strength of concrete base surface and solve the problems of ground sanding.

3. According to Qeeka Home experts, the sand on the cement floor may be caused by the unreasonable proportion of cement and mortar and improper material selection, for example, the large amount of concrete water will cause water leakage on its surface and reduce the surface strength; The grading of sand and gravel is unreasonable, which will affect the hydration and coagulation of cement; If the soil and sand we use is too fine, it is easy to cause the problem of sand on the cement floor.

4. The sanding of the concrete ground may also be caused by improper maintenance, for example, the early maintenance of the cement floor is not sufficient, resulting in the concrete surface not being fully hydrated, so the strength of the ground is relatively low, and the problem of sand is prone to occur. When we carry out cement floor construction, we must strictly follow the relevant standards for material selection, construction and maintenance.

Summary: Regarding the treatment of sand seepage and rot on the cement floor, I will briefly introduce it to you here. I hope that after reading this article, I can provide reference and help for you to deal with the sand on the cement floor in the future, and you should strictly follow the relevant standards for construction and maintenance.

Method.

1. The ground treatment will first remove the loose parts of the bulging, peeling, cracks and other parts, and the parts below 3mm and the oily parts should be brushed. After ground treatment, wash with a water gun to fully moisten the working surface until there is no more water seepage.

2. Add water to the stirring material: mix the material with water and stir, stir evenly when stirring, and the stirring time should be about 3 minutes, not too long, to prevent solidification in the mixing barrel.

3. Repair pavement for the repair of small potholes, hemp surface, peeling, exposed, fine cracks, etc., pour the stirred material on the working surface, and flatten it with a larger trowel, and do not wipe the surface twice. The initial setting time of the material is short, and there will be adhesion during the initial setting, which is not conducive to smoothing, so first use a scraper to pave a large area and then use an iron trowel to level and collect the light.

Cement floor judging potato fiber is very common in our lives, and this kind of ground is easy to produce sand after a long time. Because cement has a certain shelf life, if the maintenance department is good, it is easy to sand in the later stage. So, how to deal with sand on the cement floor?

What should I pay attention to in cement floor treatment? Let's take you to find out.

The floating ash on the cement floor is cleaned first, and then treated according to the degree of sand it rises. If the ground sand area is small, you can directly use pure cement for local repairs. However, if the cement area is large and very severe, it needs to be renovated, and the original surface layer must be removed before it is relaid.

Precautions for water excavation imitation mud ground treatment.

1. The foundation is very important.

When dealing with the cement surface, the foundation is very important, so before the hand height construction, the quality of the cement board must be checked, and there can be no shearing or grinding, otherwise it will affect its resistance. In addition, before use, it needs to be treated with a sander to see if there is a hollowing phenomenon. If the cement surface has been repaired before the decoration, then the particle phenomenon must not appear during the construction, otherwise the construction effect will be affected.

2. Pay attention to maintenance and design.

Concrete floors look very monotonous and feel very cold if they are not designed and decorated, so be sure to maintain and design them. If you have limited means, you can use self-leveling or lacquering, and the pattern can be designed according to personal preference. However, if you have a strong financial ability, you can use other ways to decorate, such as solid wood or tiles.

Article summary: The above is all about how to deal with the sand on the cement floor and what needs to be paid attention to in the treatment of the cement floor, I hope it will be helpful to you. If you want to know more about it, please stay tuned to Qeeka Home.
