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

1. Use. Wear-resistant hardening: effectively improve the wear resistance of the ground, prevent and loosen the concrete, and effectively improve the hardness and density of concrete;

Sealing and dustproofing: Penetrates into the inside of the concrete for deep sealing, prolongs the life of the concrete floor, and makes the ground easier to clean and maintain.

2. Features. The cement floor sanding treatment agent is made of colorless transparent liquid;

Non-toxic, odorless, green and environmentally friendly, it produces a chemical reaction with concrete penetration to form a dense crystal. The construction is simple, only spraying and brushing can achieve the ideal wear-resistant, hardening and brightening effects;

Permeation and curing: effective penetration of 1 20mm (depending on the site situation), chemical reaction with the substance in the concrete to form a dense whole; The compressive strength is increased by 10% to 40%, which effectively improves the hardness and density;

Brightening and impermeability: make the hardened ground shiny, have a good sensory effect, and prevent water and oil from seeping into the concrete.

You can use Agibo wall curing agent. It is suitable for the concrete mortar wall with desanding and dusting, and the putty base surface with slight pulverization on the surface is closed and hardened to improve the wall base.

The overall adhesive strength and adhesion of the layer can prevent the cracking of the decorative layer of the coating caused by the thermal expansion and contraction of the base layer, and avoid batch scraping.

Hollowing, cracking, delamination, mildew and other phenomena occur after the layer, which can effectively prevent the adhesion strength of the wall tile and the mortar wall from being insufficient.

Negative phenomena such as hollow drum peeling occur. Jiangxi Bailian viscose adhesive ****.

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.

I just shared the problem of whitewall powdering, and recently a friend asked, how to fix the white wall if it falls into sand? How can the sand fall? Mainly because of the uneven mixing of cement mortar, or the incorrect ratio of cement sand, will lead to cement sand dropping, how to solve it?

If you are facing related problems at home, you may wish to take a look at the introduction.

1. How to deal with sand falling on the wall.

Many people find that the cement wall at home will fall sand as long as they scrape it with their hands, and the clan shouts can only be solved according to the specific situation.

1. If the problem of sand falling is more serious, this is mainly because the cement mortar ratio is unreasonable, resulting in the strength of the cement mortar, so we can only remove all the sand falling walls, and then re-apply the cement mortar. And before painting, the wall needs to be cleaned, and there can be no unevenness.

2. Next, apply an interface agent or use a strong glue. Prepare cement mortar according to the correct ratio, and the ratio of cement and sand is adjusted according to 1:2 to ensure that the connection force meets certain requirements.

After mixing, it should be evenly applied to the wall, and then you can scrape putty, brush latex paint, etc.

3. If the phenomenon of sand falling on the cement wall is not particularly serious, there is also an inorganic liquid material on the market, which can play a fastening role, and there will be no problem of sand falling in the later stage. Moreover, after applying it once, it can ensure that it is effective for a long time, this method is relatively simple, but it is more suitable for the situation that the sand area is relatively small.

Second, is the cement wall of the rough house qualified for sand falling?

First of all, you need to check whether there is a problem of sand falling, if there is sand falling on the touch, it must be unqualified. You can directly find the developer to deal with the problem, eradicate it all, and then re-plaster, and we can add nylon net when mixing cement, which can play a fixed role.

The above content is about how to deal with the cement wall if the sand falls, if there is a similar situation when inspecting the house, it must be solved in time, this kind of house is not able to pass the acceptance.

Do the math how much it will cost you to renovate your home

Severe sand falling on the wall may be caused by aging, moisture or water seepage of the wall material. Here's how to deal with it:

Clean the walls of the stove: Use brushes, brooms, etc. to clean up loose sand and dust on the surface of the wall.

Confirm the leakage point: If the sand on the wall is seriously caused by water seepage, it is necessary to find the leakage point and repair it in time. Leaks can be identified by looking at the wall or using water testing methods.

Repair the wall: For the wall with serious sand fall, it is necessary to use a special wall repair agent to repair the cracks and gaps on the surface of the wall. Before making repairs, you need to clean the sand and dust from the wall surface and follow the instructions of the wall repair agent.

Strengthen waterproofing measures: If the sand falling on the wall is seriously caused by moisture or water seepage, it is necessary to strengthen waterproofing measures, such as painting waterproof paint on the wall or installing a waterproof layer to prevent moisture from penetrating into the wall.

Replace the wall covering: If the sand falling on the wall is serious due to the aging or damage of the wall material, you need to consider replacing the wall material. When choosing wall coverings, you need to pay attention to choosing materials that are suitable for local climatic conditions.

What to do if sand falls off the wall: 1. Treat the wall: clean the wall first, shovel it until the wall structure is exposed, and deal with it flat.

2. Brush interface agent: Then paint the interface agent on the wall, the interface agent can consolidate the base wall, and allow other substances to cover, which is convenient for the subsequent steps.

3. Repair gypsum mortar rough leveling: followed by the preliminary leveling of the wall, also called rough leveling and thick leveling.

4. Hanging net: This step of hanging net is not all walls, but targeted, mainly the connection of different structural bases, hydropower slots, and insulation walls that need to be tiled.

5. Fine leveling: After that, do leveling again to ensure that the wall is smooth without any protrusions, otherwise the door frames, window frames, cabinets, etc. can not be tightly fitted in the later stage.

6. Polishing putty needs to be observed with lights to see whether the wall is flat, and then Minjuda uses sandpaper and other tools to make the bridge and grind putty vertically, so that the wall is more uniform and smooth, only the smooth and delicate wall has a better effect after being painted with wall paint.

7. Brush primer: After that, brush the primer, this step must not be saved, and the primer can play a role in sealing the wall and enhancing adhesion.

8. Brush the paint and paste the wallpaper: After that, the wall is painted with latex paint or wallpaper, and the wall decoration materials can be selected according to their preferences.
