How to deal with the sand on the cement wall, how to deal with the sand on the wall

The correct repair method of sand and sand off the wall, sand on the wall, sand on the wall, sand running or sand on the wall.

Wall sanding is commonly known as wall sanding in the industry, which is caused by a variety of reasons The cement plastering mortar is not strong and has low density, which is easy to sand and desand. People in the north and south of China have different calling habits, so they are also called"The wall is sandless, the wall is sandy, the wall is sandy, and the sand is running"or"The wall is turned with sand"Wait a minute. The wall desanding is manifested as low density of mortar, softness, strong water absorption, and some even wipe the ash and sand with a hand, although it does not affect the entire building structure, but its harm should not be underestimated.

The main harm is that it is easy to cause the putty layer to bulge, delaminate and crack; If it is a kitchen and bathroom, it is easy to cause problems such as poor attachment of wall tiles and falling off tiles. Especially on the exterior wall, some of the exterior wall bricks hung on the exterior wall, if the base mortar is not strong, it is easy to cause the exterior wall bricks to fall off, and even the falling wall tiles hurt passers-by The news is not uncommon.

Later problems caused by wall desanding, such as wall bulging, delamination, and cracking, cannot be detected in a short period of time, unless they are particularly serious. Although the decorator has a variety of treatment methods, most of them treat the symptoms rather than the root cause. Once something goes wrong, you need to renovate it for at least 1 week or even longer.

What's more, if you don't fix the root cause, these problems will soon return**. Wall desanding won't go away on its own unless you put an end to them. If it is not repaired, it may be renovated many times, resulting in more manpower, material resources and time.

Especially in the decoration, because the owner is not an expert, most of the decoration company project manager or stucco master in order to save costs, with glue interface agent wall solid and other materials to repair (their main functions are different), the result can only be "hehe".

To really repair the sand and sand removal of the wall, there are special materials!

Special materials are reliable!

The correct repair method of sand and sand off the wall, sand on the wall, sand on the wall, sand running or sand on the wall.

Teach you sand control in 1 minute, see the effect in 1 hour!

The wall falls into the sand, use the sand control spirit!

The full name of sand control spirit: sand control spirit wall sand removal repair liquid.

Scope of application and application conditions of sand control.

It is suitable for the surface of building materials with cement as the substrate such as new and old plastering walls (cement sanding walls, cement plastering walls), cement walls and cement mortar surface layers.

1. It is used for the repair and remedial measures of sand-plastering wall anti-sand, insufficient marking and desanding.

2. It is used for the renovation of old walls and the prevention of aging of mortar walls of new blank houses.

3. It is used for the reinforcement treatment of special processes, such as the original ecological cement wall style of the villa.

4. The surface of other building materials with cement as the matrix.

5. Both interior and exterior walls are acceptable.

The wall surface is sanded and sprayed with a high permeability sealing curing agent can be used.

How to deal with sand on the ground.

1) Clean the ground, spray high permeability sealing curing agent to improve the strength of the ground, 2) spray the interface adhesive evenly, 3) mix the repair material with the interface adhesive, scrape the seal and copy the flat without producing thickness, and finally spray the concrete pavement curing agent

In daily life, wall cracking, sanding, peeling and hollowing are all common problems at present. So the question is, do you know how to deal with sand on the wall? What are the main causes of sand on the surface of concrete? Let me reveal the answers for you one by one.

1. Serious sanding, very low strength: first of all, the plastering layer is all removed to the base of the first roll, then watered for a day, and brushed with 108 glue for more than a day, and finally layered with 1:3 cement mortar or mixed mortar.

2. Moderate sanding and low strength: first use a grinder or iron brush to polish the surface plaster to a solid bottom layer, then water the yin transparent front for one day, and brush 108 glue for a day, and finally wipe 3-5 mm thick anti-cracking mortar.

3. Mild sanding, slightly lower strength: if the wall is smooth and tidy, brush 1 to 2 times of wall treatment. If the flatness of the wall is poor and has been repaired in many places, the cement mortar can be scraped after watering and brushing.

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

1.The cement type is not appropriate or the amount of cement is small.

2.The water-cement ratio is too large: that is, the amount of water in the mixed concrete is large, which causes water leakage from the concrete surface, which reduces the surface strength of the concrete.

3.Unreasonable gradation of sand and gravel and high mud content: unreasonable gradation of aggregate and too fine soil and sand will also lead to sand on the ground, which affects the early hydration of cement and the coagulation of concrete.

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

5.Improper maintenance.

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

7.Sand will occur if the service life is too long, aging or wearing.

Summary: After reading the above introduction, I believe you have a further understanding of how to deal with wall sanding. If you need to know more about it, please continue to ******, and more exciting content will be presented to you in the future.

Wall mortar sanding refers to the phenomenon of partial sanding on the surface of the wall after the construction of cement mortar for tiling. The existence of this problem will affect the aesthetic effect of the entire wall, and in serious cases, it will also affect the stability of the wall, so it needs to be dealt with in time.

Here's how to deal with it:

1.Find out the cause of the sanding.

First of all, it is necessary to find the cause of sanding, and only by finding the cause can targeted measures be taken. There may be many reasons for sanding, such as improper ratio of cement to sand, insufficient mixing during construction, and untreated wall surface.

2.Wash the walls.

The first step in dealing with sand is to clean the walls. Remove the sanding part with a shovel or other tool, and then clean the wall with water and a professional cleaning agent. In this way, the buildup on the wall surface can be removed, which is conducive to later repair.

3.Replenish the mortar.

The cleaned walls can be replenished with mortar. Choose the appropriate mortar material according to the degree of sanding, and then use a scraper to fill the mortar to the sanding part of the wall. Note: The supplementary mortar needs to be consistent with the original mortar.

4.Polishing.

After the mortar is replenished, it needs to be polished, and the mortar on the surface is smoothed so that it is consistent with the surrounding wall surface. The walls can be polished with a polishing machine or treated with hand tools.

5.Cleaning and spraying.

After polishing, clean the wall and keep it clean. It can be sprayed and other treatments after polishing, and the slag state makes the wall surface more flat and smooth.

Through the above treatment steps, the problem of sanding of wall mortar can be effectively solved. However, it should be noted that in order to prevent the recurrence of such problems, it is necessary to pay attention to the details of the construction process and carry out the construction in accordance with the specifications. This can greatly reduce the incidence of sanding on the wall.

Wall sanding is the easiest treatmentMethods include brushing interface agent or glue, shoveling and redoing, and spraying wall sanding repair agent.

1. Coating interface agent or glue: If the cement wall is only slightly dusted, you can directly apply the interface agent or glue early distribution and other curing agents on the wall to seal the surface of the wall and improve the bonding effect.

2. Shovel and redo: If it is weathered and old, the hollow drum cannot be repaired, or there is a problem with the proportion of cement mortar doped with sand, etc., and the sand and sand are particularly serious on the wall, then the old mortar layer can only be removed first, and then the sand can be re-plastered to avoid the later brick hollowing or even falling off. This is the most radical solution, but it requires a lot of manpower, material resources, money and time.

3. Spraying wall sand repair treatment agent: only need to spray and brush on the surface of the cement wall to solidify the sand and gravel, so that it will no longer fall ash and the effect will be long-lasting and effective. The use of repair agent can avoid the trouble of re-scraping sand, and can save costs and facilitate construction.

Causes of sanding on the walls

1. Insufficient amount of cement: Under normal circumstances, the ratio of cement mortar on the wall is 1:3. If the amount of cement used is too low in order to save materials less than this standard, its structural strength will definitely be affected.

2. Improper water-cement ratio: In the process of mixing mortar, sometimes too much water will be added due to not mastering the dosage. After such mortar is plastered on the wall, it is not only loose and easy to fall off, but also will continue to seep water from the surface, so the strength of the mortar will be reduced a lot.

3. Sand quality problems: If the sand of the mixed mortar is too fine, there are many impurities (including ash, etc.), which will also affect the coagulation of cement and sand and land materials, so that the wall plastering layer will lose its strength due to poor bonding.

Treatment method of wall sanding:

1. Cause analysis.

1.unreasonable cement mortar ratio or improper construction;

2.The surface of the base layer is not sufficiently bent, such as not being cleaned, not waterproofing, etc.;

3.The ambient humidity is too high or the temperature is too low, causing moisture to condense on the wall;

4.Poor quality of materials, such as insufficient cement strength, etc.

Second, the treatment method.

1.Cleaning the wall: Wash the wall with clean water and detergent to remove dust and stains, and at the same time check that the surface of the base layer is flat, if there are uneven places that need to be repaired.

2.Priming: Primer is applied to the surface of the base layer to enhance adhesion and moisture resistance, while preventing subsequent paint from peeling off.

3.Leveling treatment: For uneven walls, leveling is required, and materials such as gypsum powder are used to fill the defects of the wall and make the wall smooth.

4.Waterproofing: Waterproofing the wall to avoid moisture penetrating into the inside of the wall and causing sanding on the wall.

5.Choose high-quality materials: Choose high-quality cement, sand and other materials during the construction process to ensure that the mix ratio is reasonable, so as to reduce the occurrence of sanding.

6.Remedy: If the wall has already appeared sanding, it can be repaired with professional caulk, while strengthening the treatment and waterproofing measures of the base surface.

3. Precautions.

1.Before construction, read the instructions of the materials carefully, and carry out the proportioning and construction according to the requirements;

2.Ensure that the surface of the base layer is dry, flat and clean, otherwise it will affect the quality and adhesion of the coating;

3.In the process of construction, it is necessary to pay attention to protecting the surrounding environment and avoiding damage to other items;

4.If there is a sand phenomenon, measures should be taken to repair it in time to avoid affecting the overall decoration effect.

Sanding <> walls is a relatively common problem, and here are some simple ways to deal with it:

Wipe the wall: First of all, you need to clean the dust and debris on the wall with a clean rag or vacuum cleaner to better deal with the problem of sanding.

Use glue: apply an appropriate amount of glue to the sanded wall, then fill it with a scraper, wait for it to dry, then polish it with sand patting paper, and finally paint it.

Use caulk: Apply an appropriate amount of caulk to the sanded wall, then fill it with a scraper, wait for it to dry, then sandpaper it is sanded, and finally painted.

Use paint: Apply an appropriate amount of primer to the sanded wall, wait for it to dry and then sand it with sandpaper, and then paint and paint.

Please note that when dealing with sand problems, it is necessary to select suitable materials and tools for treatment, and carry out construction and maintenance according to the actual situation. If the problem of sand raising is serious or cannot be dealt with by yourself, it is recommended to seek a professional decoration company or worker to deal with it.

The method of sand on the wall is as follows:

1.Clean with compressed air or a broom. To clean the wall, you can use compressed air to blow away dust and debris deposited on the surface of the wall, and then gently brush it over the wall with a soft brush or broom to help clean it thoroughly.

2.Scrape off the old paint layer of lead Luch. Some of the old paint layers that have been sanded may have touched the interface of the new paint and prevented the new paint from adhering to the wall, at which point the old paint layer can be scraped off with an electric scraper or washed with a high-pressure water gun to peel off the old coating bark and other undesirable materials.

3.Use putty or perlite. If the wall itself is old and needs to be repaired, then use perlite and cement or professional wall putty to strengthen the surface of the wall, smooth out the rough areas of the wall and wait at least 24 hours for the surface to dry completely.

4.Spray new latex paint. Finally, paint the walls with one or two coats of new latex paint to enhance the aesthetics of the appearance. Paint can be applied to a roller or spray gun for easier handling.

It is important to note that it is important to keep the room ventilated and use personal protective equipment such as masks, gloves, etc. when carrying out repair work. Before choosing to use any cleaning or painting product, please ensure that you read it carefully and follow the instructions given by the manufacturer.
