The following latex paint, wallpaper, diatomite PK, affordable latex paint can be preferred, focusing on home style can be preferred wallpaper, focusing on environmental protection and budget can choose diatomite, diatomite brand can be considered Tmall Yunquan. Of course, different wall materials can be selectively applied to different walls to meet the needs of different living, but no matter what kind of wall materials should be recognized regular business products, especially for environmental protection has high requirements, more carefully check the product indicators.

Latex paint, wallpaper, diatomaceous earth PK
Who is better in the end
Since the home wall coverings latex paint, wallpaper, diatomaceous earth three worlds of the situation, the community has been controversial on the three, the love of the people as a guideline, the hate of the scorn. Merchants in order to their respective interests is also to take each other slammed, denigrate the mentality: a variety of PK, experiments, data to see people dazzled ...... Here, don't pretend brother would like to say, you have considered the feelings of the wall cloth?
PK results: latex paint, wallpaper, diatomaceous earth in the end which is better, the scientific community so far inconclusive.
In fact, the use of ordinary consumers are increasingly concerned about environmental protection as a gimmick, will be three completely different materials to do the comparison, such an experiment, in itself, is not very meaningful. Objectively speaking, latex paint, wallpaper, diatomaceous earth belongs to three different industries, when a product can develop into a mature industry, its existence must be reasonable.
As for people most concerned about environmental protection, each industry has the relevant standards set by the state, each industry also ignores the national standards for the production of unscrupulous businesses, whether latex paint, wallpaper, diatomaceous earth, the market can be found from dozens of dollars to thousands of dollars ranging from the product, consumers need to be rational when choosing, keep your eyes peeled and try to choose a big brand is more reliable.

Don't listen to the merchants who are fooling around
The one that suits you is the best
"Our diatomaceous earth can adsorb formaldehyde, and my latex paint can purify the air ......." When you hear the shoppers boast about the various additional features of their products and indecisive, do not forget the original purpose of our choice of wall coverings - decoration. Solve the problem. Latex paint / wallpaper (including wallpaper, etc.) / diatomite?
1. First, a brief introduction to the construction of the three wall coverings
The process of grass-roots treatment of the wall is: repair (gypsum, cement mortar, etc.) - sealing (on the interfacial agent) - leveling (the first thick leveling, and then leveling, fine leveling, fine leveling will be used to putty).
Rolling latex paint
Then brush latex paint: sanding with gauze, clean the surface of floating dust, paint a primer, and then brush the top coat twice (domestic latex paint almost all have to be on-site mixing of paint, mixing paint need to be mixed into the color paste, mixing out of the color and the target color may be chromatic aberration);
Playing wallpaper
And paste wallpaper is: after the grass-roots level of the wall. Apply a layer of base film on the wall, and then use the environmental protection adhesive to pave the wallpaper according to the design.
Diatomite
Diatomite construction is in the grass-roots level after treatment, adjust the color of diatomite on the wall, on the wall there are many kinds of S construction, depending on what effect to be.
You have found, diatomite and latex paint are required to modulate the color, while the wallpaper is not required to mix the color.

Is diatomaceous earth really purifying?
Re-recognize diatom mud wall
Speaking of diatom mud, in your mind is not immediately appear to absorb/purify formaldehyde, regulate humidity, release negative ions. A variety of sellers exaggerate the advantages of the sky. The fact is how? First of all, there are two misunderstandings about diatomite:

-Diatomite is not equal to 100% diatomaceous earth
Diatomite is the remains of the diatom after the death of the diatom (diatomaceous earth), mixed with gypsum, lime and other materials (to increase the viscousness) and become. Diatomaceous earth is the main raw material of diatomaceous earth, diatomaceous earth's porous structure makes its adsorption capacity is higher than that of activated carbon, but only adsorption.

Diatomaceous earth in diatomaceous earth content, according to the "diatomaceous earth self-regulatory convention" in the provisions of the diatomaceous earth content of the optimal range of 15% -35% (not the higher the better, because the content is too high, you need to use the organic gel in order to meet the requirements of the wall viscosity), will increase the risk of indoor pollution. The diatomaceous earth content of the best range is 15%-35% (not the higher the better, because the content is too high, need to use organic gel to achieve the viscosity requirements on the wall, will increase the risk of indoor pollution), no matter how much adsorption will be saturated, and this diatomaceous earth content is so low, the amount of adsorption of formaldehyde really quite limited.
A diatomite product page
-Diatomite decomposition of formaldehyde is very limited
The above businessman also said, if only adsorption and not decomposition, if the absorption of formaldehyde will be saturated, will also be released, the most important thing is that it can be decomposed, he said himself can be decomposed, but the specific can not be decomposed, all walks of life have different opinions, I learned that titanium dioxide light decomposition of formaldehyde, the reaction is able to occur in the laboratory. This reaction in the laboratory is able to occur, but that is in a variety of appropriate experimental conditions occur, in normal indoor conditions, this reaction even if there is, but also weak.
In short, in order to diatomite can decompose formaldehyde this reason to buy diatomite, is very unnecessary, in order to its face value and so on, or can.
In addition to the above two points, we will take the diatomite as a common wall decorative materials to see on the line, its biggest feature is Indeed, can regulate the indoor humidity, diatomite in Japan is often produced as a bath mats, umbrella bracket, etc., is because it can absorb water, at the same time, if the room is relatively dry, it can also be absorbed by the release of the water to achieve the effect of regulating the indoor humidity.
As latex paint and wallpaper, to see the following performance of diatomite:
Environmental protection: Well, a good diatomite itself does not release formaldehyde, this is still considered environmentally friendly, but note that the formaldehyde absorption is easily saturated and adsorbed on the wall of formaldehyde, will be released when the hot air conditioning or floor heating, so open the window to ventilate more.
Decorative: diatomite decorative than latex paint rich, diatomite can be a variety of colors, patterns, like painting on the wall, but also raised, depressed, and other three-dimensional effects, and then than the wallpaper is still inferior. A few days ago to visit some building materials market, saw the diatomite color, texture, feel and carving significantly more ~ decorative and not inferior to latex paint.
To the following effect, in fact, there is no impact ~ ↓ ↓ ↓ ↓
Price: the same is a website with high sales of an "interior wall environmental protection paint" diatomaceous earth (the use of the product and the construction of the company's personnel, free of charge warranty for 2 years), 70 square meters of the house assuming that the 60 square feet of the painting area, about the need for 3 barrels, that cost 1139 * 3 = 3417, in addition, the brand said to brush a layer of putty layer on top of a layer of "interior putty layer reinforcing substrate" Golden Shield, about 2 barrels, that is, 392 * 2 = 784 yuan, a total of 4201 yuan of materials, labor costs will be different depending on the construction process. Generally speaking, the price of diatomaceous earth will be about 70%-140% higher than the price of latex paint.
Life expectancy:?15-30 years.
Repair and renovation difficulty: As the construction of diatomite is relatively simple, where you need to repair when directly painted there. Renovation of diatom mud, you also need to remove the wall, redo the grass-roots treatment, re-construction.

Environmental comparison
Emulsion paint and wallpaper of various performance comparison
Emulsion paint: domestic production and construction technology is relatively mature, the state for the interior wall emulsion paint has strict quality control standards, so the regular brand of emulsion paint products is relatively safe. And, after years of improvement, many low voc (will produce harmful volatile organic compounds), nearly zero formaldehyde products more and more, but also appeared a number of new functional products that can purify the smell and improve air quality.
Wallpaper: compared with latex paint, the domestic wallpaper industry is relatively chaotic, the national standard is not uniform, the market has a lot of imported brands, while the domestic wallpaper of mixed quality. At present, the domestic market is still cheap to pvc material, pvc wallpaper is likely to have plasticizers, but also volatile organic compounds.
In addition, the wallpaper used in the selection of base film and glue is more important, the wallpaper selection of environmental protection, auxiliary materials did not choose good are equal to nothing, the amount of formaldehyde rubbing up. Base film is a protective film between the wallpaper and the wall, curing and protection putty surface layer, easy to paste wallpaper. Wallpaper glue is the biggest problem affecting the degree of environmental protection, at present, the wallpaper glue on the market there are four main categories:
A. Powder + pulp: powder is mainly potato starch, pulp is mainly white glue (polyvinyl acetate) or a transparent glue (one of the raw materials of transparent glue is formaldehyde). The use of powdered glue poured into the water to mix, and then added to the pulp to enhance viscosity. Some businesses in order to save costs, will use transparent glue instead of white glue, so it is best to smell the smell when shopping, ask for test reports.
B. Wet glue: the raw material is glutinous rice starch, corn or wheat starch, when used to add water to dilute on the line, is currently the most commonly used wallpaper glue. But there will be unscrupulous merchants in which to add substandard chemical synthetic glue to increase the bonding force.
C. Rabbit glue powder: the raw material is modified potato starch or plant fiber, its environmental performance is not as good as glutinous rice wet glue.
D. Barrel finished glue: direct use, its main ingredient is also white glue - starch, but it is mostly imported glue, very expensive, good environmental performance.

(2) decorative comparison
Latex paint: latex paint color is very much, almost any color can be adjusted, and, in recent years, a lot of composite color and three-dimensional effect of the texture of the paint. But the domestic mixing paint may have color difference, mixing the color and on the wall - after drying the color will also have a tiny color difference, the pattern is still not as rich as wallpaper.
Wallpaper: rich pattern is the biggest feature of the wallpaper, no matter what pattern can be realized through the wallpaper, and there are convex, velvet, plants and other crafts and materials used to create almost any atmosphere you want.
(3) price comparison
Latex paint: latex paint varieties are more, there are a variety of functional coatings, the price range is also larger to a brand of "second generation five-in-one net flavor" paint 18L * 2 + primer 18L * 1 set, for example, 70 square meters of the house about 2029 yuan (purchase) A set, excluding labor costs), another brand of "gold net flavor 5 in 1" topcoat 5L * 2 + primer 5L * 1 set, 70 square meters about to buy 3-4 sets of sets, spending about 698 * 3.5 = 2443 yuan (excluding labor costs). (These two brands are well-known brands of domestic latex paint, two brands of theoretical paint consumption of about 12-14 square meters / L / single)
Wallpaper: talking about latex paint you may know a lot of brands, talking about wallpaper you can think of what brand? There seems to be no very well-known domestic wallpaper brands. The better wallpaper on the market seems to be imported. Therefore, its price is relatively high. A very good sales on a website "simple modern living room bedroom room background wall linen wallpaper" 59 yuan / square meter, the area of 30 square meters that package accessories package installation (I do not know with which kind of glue), assuming that 70 square meters of the house paved the area of wallpaper and wall paint in line with the area of pavement = (70-kitchen and bathroom area is set to 10) * 3 = 180 square meters, that is, the cost of 106 square meters. 180 square meters, that cost 10,620 yuan.
Note: painted latex paint or wallpaper wall area is calculated as: the use of the area (total area minus the area of the kitchen and bathroom) multiplied by 2.7-3.5.
(4) service life
Latex paint: the main factor in determining the life of the latex paint is the base material, that is, the film-forming agent of the adhesion of the film for the duration of time, specifically in its ability to withstand scrubbing and alkaline resistance. The specific performance is shown in its scrub resistance and alkaline resistance. Scrub resistance reflects the ability of the paint to adhere to the surface, while alkaline resistance reflects to a certain extent its ability to resist environmental erosion. The life span of latex paint is also affected by the condition of the wall, humidity in the space, human factors, etc. Usually, the life span of latex paint is 5 years. Usually the life of latex paint in about 5-7 years, after which, latex paint will appear different degrees of powder, peeling phenomenon.
Wallpaper: wallpaper itself, the strength and performance of the material, and wallpaper binder use of the time limit, which determines the service life of the wallpaper, and the latter is the most important. Many wallpapers appear warping, leakage, yellowing, etc., are because the binder quality is not good. Usually paper wallpaper life in about 5 years, pvc wallpaper life can be up to 8-10 years, cloth wallpaper is a little longer.
(5) repair renovation difficulty
Latex paint: repair directly brush the need to repair the place can be, but it is easy to have color difference. Renovation, the best way or to shovel the wall, redo the grass-roots treatment - sanding - a bottom two sides. Directly on the latex paint surface to brush the new color, will affect the decorative effect and service life.
Wallpaper: wallpaper repair depends on the pattern, but most of them are still all torn off and replaced. Renovation of wallpaper is more convenient for different materials of wallpaper using a slightly different way to tear down the wallpaper, check the wall for damage, no, then directly paste the new wallpaper on the line.
