Is there still a use of lime brush wall, and what are the advantages and disadvantages of lime brush

Have you ever seen a master worker paint a wall with lime mortar? Those slimy lime mortar, when just painted on the wall, the wall is not white and not hard, after a period of time it becomes white and hard, to understand this truth, we must start with the composition of lime mortar.

1. Lime slurry comes from limestone, the main component of limestone is calcium carbonate, which often gathers into a large strata, limestone is millions of years ago in the ocean polyps and shellfish and other animals deposited on the seabed after death, and the sediment is constantly covered on the corpse and formed.

2. Due to the movement of the earth's crust, a part of the ancient ocean rose to become land, and it became limestone. After limestone is mined, it is calcined and turned into quicklime (the chemical name is calcium oxide), and after the quicklime is combined with water, a chemical reaction occurs to turn it into hydrated lime (the chemical name is calcium hydroxide). After the hydrated lime used to brush the walls is mixed with an appropriate amount of water, the lime slurry is made.

Knowledge of painting walls.

1. The wall is generally divided into two situations, one is the wall that has never been painted, and the other is the wall that has been painted. The treatment of two different wall surfaces when painting is also different. Generally, new wall painting only needs to do an alkaline and moisture content test.

2. But if it is a wall that has been painted, you need to deal with some stains on the wall first. For dirty areas, wipe with a sponge or rag first, but be aware that if water is used during the cleaning process, you need to wait for the wall to dry completely before painting.

3. For the parts of the wall that are more damaged, such as cracks, etc., the wall needs to be repaired before painting. But if the wall is originally well preserved, then you can paint the wall directly, and you don't need so much preparation.

4. Remove the original old wall, which can ensure that the wall painting effect is better. Putty is also difficult to follow. After the old wall is removed, you can then use putty or scraping powder to level the wall to make the wall smoother.

5. After the wall is leveled, the next step is to polish, mainly to polish the uneven places on the wall with sandpaper to smooth and smooth. After the above steps are completed, you can enter the step of painting the wall. Generally, the paint is divided into two parts, first the primer, then the topcoat, the general principle is "one bottom and two sides", that is, one primer and two topcoats.

No one should use this anymore, because lime brushing the wall is not fashionable, there is no latex paint beautiful, but lime brushing the wall is also good, there is no formaldehyde, and there is no effect on the human body.

It can be used on occasions with low requirements, and the general home decoration is brushed with latex paint, which is not very expensive, and the effect is quite good, but the lime wall has one of the biggest advantages, that is, the environmental protection performance is particularly good, there is no formaldehyde, and it will not cause harm to the human body.

Some small factories, small workshops and relatively poor places are still used.

What are the advantages and disadvantages of lime painted walls? How Long After Lime Painted Walls To Live Lived? Lime stucco wall environmental protection pollution-free, it is more in line with environmental protection requirements than putty paste and latex paint mixed with chemical ingredients, the disadvantage is that the ash is not smooth, not beautiful, and the brightness is not good.

Not afraid of water, you can use a damp cloth to scrub the outside of the stain.

The advantage is that it is relatively simple and can better protect the wall, but the disadvantage is that it is easy to crack, and it takes at least a week or so to live in it.

The advantage is that it is more beautiful and beautiful, and the disadvantage is that there may be some peculiar smell, and under normal circumstances, it needs to be ventilated for at least 7 days before you can move in.

1. Disadvantages: hydrated lime.

The paste is better than putty paste and latex paint mixed with chemical ingredients.

Relatively speaking, it is more environmentally friendly, but the effect is not as good as the paint, because it does not contain glue, the stain can not be wiped and the color and fineness are not as good as the wall paint.

2. Advantages: In addition to the stains that can be scrubbed with a damp cloth, the texture and overall effect of the hand touch are more delicate, smooth, and three-dimensional, and more durable than ordinary wall paint.

Lime paste is a dispersed, pure natural white slaked lime.

based on carbonates.

Fillers and no plastic diffusion materials are used as binders.

As a real mineral coating, the slurry material delicately made by a special process has low shrinkage, no cracking and no powder after hardening.

It is not recommended to use, and the original base is not firmly bonded, and the wild ruler will affect the later construction. The reason is very simple, first of all, the drying shrinkage rate of these two is different, and the drying shrinkage of lime mortar is large in comparison, so it will crack. Secondly, lime mortar will cause poor stability of cement mortar.

Cement mortar shall not be plastered on the lime mortar layer, the reason is: lime is a kind of gas-hard inorganic cementitious material with calcium oxide as the main component. Lime paste is a paste obtained by curing the simple ridge of massive quicklime with more water, and its main component is Ca(OH)2.

In the atmospheric environment, calcium hydroxide will react with carbon dioxide in the air in a humid state to form calcium carbon, if the cement mortar is smeared on the lime mortar layer, carbon dioxide will not be able to penetrate, hardening will stop, lime plaster can not meet the design strength requirements; The overlay gypsum ash shall not be plastered on the cement mortar layer, the reason is: in a humid environment, no air-hardened materials shall be used. When the cement mortar is humid, the moisture condenses on the surface, and the lime paste and the cement mortar base layer are prone to delamination at the joint part, causing the covering layer to fall off.

Can Lime King be used to plaster walls? Hello dear, you can, brush the wall with Lime King, the texture and overall effect of the hand touch will be more delicate and smooth, the three-dimensional sense will be stronger, and it is more durable than ordinary wall paint, and at the same time, you can use a damp cloth to scrub after there are stains. After adding water to the lime, after a period of time, it will react with the carbon dioxide in the polite calcium carbonate, and calcium carbonate is the main component of the stone, so the lime lead Kaimeng is not polluted, and it is also a disinfectant substance, and it is completely environmentally friendly to brush the wall with lime.

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

In recent years, more and more people will use lime to paint the wall when decorating. However, since many owners are renovating for the first time, they are not aware of the order of renovation. So, can lime walls be painted with latex paint directly?

What are the advantages of lime walls? In fact, these two questions have always been a problem in the hearts of decorators, so let's explore the answers together!

1. Can lime walls be directly painted with latex paint?

Lime walls cannot be painted directly with latex paint. Because the surface of the lime wall is rough, and the flatness is not enough. The most important thing is that if the latex paint is directly brushed on the lime wall, the latex paint may crack and peel.

Usually when this phenomenon is encountered in the decoration process, the decoration workers will brush the glue on the lime wall, because this can effectively increase the adhesion of the putty layer.

2. What are the advantages of lime walls?

1. Paint the wall with lime, which is more environmentally friendly than latex paint and putty paste containing chemical components. However, it should be noted that the effect of painting the wall with lime may not be as good as that of paint, because lime does not contain mammoth glue, stains cannot be wiped clean, and the fineness and acceptance are worse than wall paint and latex paint.

Destroying the Bureau. >2. It should be noted that when painting the wall with lime, you must wait until the outer layer of lime is dry before you can carry out the next step of decoration, otherwise it will make the wall appear spotted, which will eventually affect the aesthetics. In addition, in the process of brushing lime slurry, it is necessary to continue to stir the lime slurry, otherwise the lime will precipitate, and the wall will also appear with different shades of patterns.

The lime wall cannot be directly brushed with latex paint, because the Shiyou stuffy gray wall is absorbent and alkaline, and the latex paint is not easy to adhere. Before painting latex paint, the following treatments need to be carried out:1

Clean the walls: Wash the walls with clean water and mandated hail soap to remove dust and dirt. 2.

Repair the wall: Fill in the cracks and depressions in the wall to make it smooth. 3.

Brush latex paint: Wait for the primer to dry before applying latex paint. Note:

Before painting latex paint, you need to make sure that the wall is dry, otherwise it will affect the adhesion and quality of the silver paint.

No. It is necessary to treat the wall surface roughness (such as ditching and dotting) so that the putty powder scraped after scraping can be closely pasted with the wall. In order to ensure long-term use.

1. Paste non-woven fabric on the lime wall, scrape a layer of gypsum powder, then scrape putty (powder) twice, polish and brush latex paint after polishing;

2. Shovel off the lime layer, scrape a layer of gypsum, then scrape putty (powder) twice, polish and brush latex paint.

Standard classification. Our national standard divides the finished putty into: general putty (type Y) and water-resistant putty (type N). Note: The product inspection report indicates which model standard index is used for inspection.

General putty (type Y) is used in places where water resistance is not required. It is composed of double fly powder (i.e. calcium carbonate), starch gum and cellulose. Among them, starch gum is a kind of gum that dissolves in water, dissolves in water, and is not resistant to water.

Water-resistant putty (n-type) is used in places where water resistance and high bond strength are required. It is composed of double fly powder (i.e., calcium carbonate), gray calcium powder, cement, organic rubber powder, water retention agent, etc. It has water resistance, alkali resistance and bond strength.

After the test of water resistance and alkali resistance, no blistering, cracking and falling off were found, and there was no abnormality in 48 hours of immersion in water and 24 hours of alkali resistance. As moisture absorbs year after year, the water-resistant putty layer of the wall will be maintained to be harder and stronger.
