How to choose a good paint? How to choose paint?

1. Look for environmental protection labels.

If it is an environmentally friendly paint, the paint barrel will have a clear China environmental protection product certification mark, which indicates that the product meets the national environmental protection standards and meets the minimum indicators for decoration and use. In addition, the big brand paint products not only meet the national standards, but also meet the international standards, such as ISO9001 environmental protection testing and certification.

2. Check the product sample.

In the paint store, there are relevant construction effect models for the main products. Before buying the product, you can carefully check the sample effect, the sample paint film made by good paint products is delicate, strong scratch resistance, high hardness, and will not appear paint film peeling and paint film cracking. If the paint film effect is not good, it means that the product is a substandard product, and the product is even poor.

3. Test the effect of the product.

When buying paint products, you can test the samples yourself. For example, whether there is a pungent smell when the paint is just opened, how the flatness and covering power are after painting, whether there are bubbles or particle protrusions after the paint film is dry, whether there will be yellowing in the short term, etc.

1. There should be an environmental protection product mark.

Health and environmental protection products are the first choice of consumers at present, and the packaging of health and environmental protection products has passed the China Environmental Protection Product Certification, and the China Environmental Protection Product Certification Mark is the most stringent certification mark in the country. Good paint has high hardness, good scratch resistance, is not easy to scratch, and can play a good role in protecting wood.

2. Feel the sample.

Good paint, you can know it by touching it. Good paint has high solid content, plump and moist feel, delicate and silky, while inferior paint due to low solid content, even if it is painted many times, it still feels brittle and thin, and paint containing impurities will have obvious graininess.

As an indispensable material in home decoration, paint is not only a messenger for dressing up the home, but also a dangerous product with formaldehyde. 1. Pay attention to the environmental protection product mark: health and environmental protection products are the first choice of consumers at present, and how to identify health and environmental protection products in the face of various certification certificates placed on the counter.

Experts remind consumers that with the country's standardization of packaging, there are China environmental protection product certification marks on the packaging of health and environmental protection products, which is the most stringent certification mark in the country. Qualified paint products will have a test report issued by a third-party testing agency, and consumers can ask the merchant for and identify this test report. 2. Look at transparency:

Most of the excellent paint brands in China provide product sample experience in specialty stores. Consumers observe the transparency of the sample, and the paint with high transparency is shiny and moving, which can highlight the natural texture of the wood, and can well modify the wood and make the wood more exquisite and beautiful. And those paint samples with whitish surfaces are definitely inferior products.

3. Scratching model: good paint has high hardness, good scratch resistance, is not easy to scratch, and can play a good role in protecting wood. Consumers can try to scratch the surface of the sample with their fingernails or paper, and the surface of the good paint will be smooth and undamaged, while the paint with low hardness will be noticeable.

4. Touch the model: whether it is a good paint or not, you can also know by touching it. Good paint has high solid content, plump feel, delicate and silky, while inferior paint has low solid content, even if it is painted many times, it still feels brittle and thin, and the paint containing impurities will have obvious graininess.

5. Specific yellowing resistance: yellowing resistance is an important indicator to reflect the performance of paint, and the paint with poor yellowing resistance leads to discoloration and oldness of furniture, which is especially obvious in white paint and light-colored paint. Under strong ultraviolet exposure, the worse the quality of the paint, the faster the yellowing will be.

1. Look at the shape.

When the eco-friendly paint is turned on, a layer of resin floats on the surface of the paint. After stirring, the paint texture is thick, and the bright paint color is white and crystal clear; The matte paint is translucent and slightly cloudy, without redness, blackening and sedimentation. When the eco-friendly paint drips, it is in a straight line and continuous.

When the inferior paint drips, it is intermittent and has a caking phenomenon.

2. Smell. The smell of environmentally friendly paint is mild, elegant, and the aromatic fragrance is pure; Inferior lacquer can emit a strong pungent odor or other unidentified odors. Even if some inferior paints are added with spices and pretended to be environmentally friendly paints, they still smell bad.

3. Check the content of VOCs.

VOC refers to the total amount of organic compounds contained in paint. Volatilization of organic compounds can cause harm to the environment and the human body, and the amount of these solvents should be minimized when carrying out home renovations. However, VOC is also the main part of the paint film-forming, if the VOC content is too low, it may lead to a decrease in the viscosity of the paint, powder loss, blistering, cracking and other situations.

Generally, doors and windows, household wood, and metal surfaces are more suitable for alkyd enamel. Latex paint is mostly used for home walls. Good latex paint has strong hiding power, strong adhesion, scrub resistance, strong and long-lasting paint film, long-lasting color and mildew resistance.

Buy the least consumption: consult the merchant about the number of paints and the area of painting, calculate the amount and cost of materials per square meter, do not be deceived by the unit price of each group (barrel), the paint is composed of solid components (film-forming substances) and volatiles, the solid content is high to 70 to 80, the low is less than 10 to 20, the unit is often very expensive, more expensive and wasteful, and the quality effect is poor.

Buy professional and supporting: first-class products are often more professional, according to the texture, color, structure or use of the object has different design and strict process requirements, and provide technical guidance and after-sales service, regular manufacturers are provided with colorful model color cards.

Buying business-led: the best-selling degree of the product, whether it is dominant, whether it is prominent from the position of the shelf, and the size of the display area can be inferred.

Poor quality wall paint can produce pungent gases that can damage the lungs, trachea and nasal passages if inhaled over time. When choosing paint, you must choose environmentally friendly and low-carbon healthy paint, but at present, there are too many domestic brands, all of which are said to be healthy paint. When choosing, look at its color to be pure and fresh, followed by the smell to be light, and third, the feel to be slippery.

Last year, our company used the desert oasis paint in Zhongshan, Guangdong, which feels good, you can go and find out.

To choose a good paint or coating, you must first look at his ten-ring certification, that is, the international environmental quality system certification, and generally large and well-known international enterprises will have this certification! Secondly, we must choose the kind of big brand, at least there is a guarantee, whether it is in sale or after-sale!

Paint is one of the most popular wall materials, most people only think that paint is just a choice of shade, but in fact, there are many types of paint, and there is a certain amount of knowledge when choosing. Eco-friendly paint, Bangyun paint recommends you:

1.Before buying paint, you can take the paint card and the floor, the curtains together to see if it is coordinated, because the area of the color card is very small, it will become darker after being painted on the wall, and it is advisable to pay attention to the color when choosing it. The color on the color card may be slightly different from the substance, and the substance shall prevail.

2.Many people like to paint their own walls, but the effect may not be ideal, it is best to use ready-made machine-adjusted colors, with thousands of options to choose from. However, the tinting service is generally only provided by the designated paint factory showroom, and it is necessary to pay attention to whether it is an order or a timely tint for pick-up before purchasing, and the price of the tinted paint will be slightly expensive.

3. To decorate the room for children, it is best to choose natural paint or water-based paint without chemical smell, because the heavy metals contained in the paint will affect the development of intelligence. In addition, children like to graffiti on the wall, so it is advisable to use washable paint.

4.Families living in damp areas are advised to choose latex paints with enhanced anti-mold effect to prevent mold and blistering on the walls.

5.The better the resin quality and higher content of latex paint, the more elastic the paint film will be, which can resist the tensile force of minor cracks, and is easier to clean, and has better waterproof effect. However, the actual paint cans are not marked with resin composition, so it is difficult to distinguish, so consumers can only pay attention to the functional introduction on the color card and listen to the master's opinion.

6.When choosing paint, pay attention to the instructions on the paint can, such as the type of paint suitable for painting, the suitable thinner, the drying time required, and the area that can be covered per can, etc., to determine the amount of paint needed.

Now it must be the first choice of water-based paint, which is environmentally friendly and non-toxic.

Look at the brand, look at the quality, and its professional effect, such as wear-resistant and waterproof, formaldehyde resistant and so on. Now paints like Dulux, Nippon, these brands of paints are listening well.

Fairness is king! Kyolong lacquer is recommended.

Brands, Nippon, Dulux, Carberry, Bauhinia, Red Apple, Three Trees, these are all well-known environmental protection brands in China. **, it is recommended to go to a formal authorized store, the above brands ** are guaranteed, and there should be no problem with the quality.

performance, analysis of the wall environment, according to the local climate or building structure, etc.

**, the performance is suitable, not necessarily the most expensive.

1. Try to choose brand paint.

2. See if it is a "green" environmental protection product, and pay attention to the fact that all kinds of paints and coatings are basically marked with the word "green". But the "green" building materials on the market are not necessarily environmentally friendly? What kind of products are "green" and environmentally friendly?

Is it that meeting national standards is equivalent to environmentally friendly products? The confirmation of green products should be confirmed by the Certification and Accreditation Administration of the People's Republic of China, and the "Ten Rings" icon of China's environmental labels should be recognized when purchasing green home improvement and building materials, which is also the easiest and most effective way to identify the authenticity of "green products".

3. Look at the weight, don't be sloppy, there are various paint packaging specifications on the market, you should pay attention to it when buying.

4. Understand the consumption of paint: consult the merchant about the number of times the paint is painted and the area of the paint, calculate the amount and the cost of materials per square meter, the paint is composed of solids (film-forming substances) and volatiles, the solid content is high to 70% to 80%, and the low is less than 10% to 20%.

First, it is necessary to see the quality qualification test report of environmental protection coating products, especially the VOC content on the quality inspection report.

Second, it is necessary to see whether the coating meets the national mandatory standards and whether it is certified by China's environmental label.

The third is to pay attention to the brand when purchasing, and it is best to choose products produced by well-known large enterprises. It is also necessary to observe whether there is rust and leakage at the joints of the iron drum; Pay attention to whether the logo on the iron drum is complete; Imported products also depend on whether there is a description in Chinese.

The relative transparency of paint purchase is high, and the choice of brand is best from a few big brands, Nippon, Dulux, and masters. The color of them can be adjusted by the machine, which is very convenient. The degree of environmental protection is actually about the same, you don't need to choose a very expensive one, just a mid-range one.

The following points should be paid attention to when purchasing paints:

There are many kinds of paints, different properties, and their excellent quality depends on their protection, decoration, craftsmanship and economy, environmental protection and other aspects of comprehensive trade-offs, in order to facilitate construction and ensure quality, you can refer to the quality indicators on the manual when purchasing.

Protection: The paint film is required to have a certain mechanical strength, necessary heat resistance, water resistance and weather resistance, and be able to resist the corrosion and cold resistance of chemicals. At the same time, it must be elastic enough to withstand deformation caused by changes in the moisture content of the wood.

When purchasing, you can refer to the quality indicators on the manual.

Decorative: The paint film is required to be plump and thick, flat and smooth, with strong light or matte. For transparent paints, it is necessary to be able to clearly show the grain of the wood. For opaque paints, it is required to have an aesthetically pleasing color that will last for a long time.

Manufacturability: It is required to be convenient for construction and fast drying. Economy: low cost and low cost. But don't use paint that is past its shelf life for the sake of cheapness, as the shelf life of paint is generally one year (from the date of manufacture).

Environmental protection: environmental protection factors have attracted more and more attention, and the paints currently sold on the market contain more or less free isocyanates and xylene, which are harmful to the human body. If you look at the long-term effects on the human body, of course, the varieties with lower content are preferred.

Try to choose brand paint, there are often advertisements on TV, so you don't need to introduce them. When buying paint, don't tell the painter that you want to buy paint, learn about the approximate dosage from the side, go to the store to buy it yourself, and don't tell the store about the painter who gave you construction.

2. If you don't choose brand paint, then I suggest that you pay attention to the origin of the paint when purchasing: at present, the paint in our market is divided into two major production areas (I don't know how other places), Shanghai, Jiangsu, Zhejiang and Guangdong, my suggestion is to choose Guangdong goods, because in the process of my construction, I feel that the quality of paint Guangdong goods at the same price is better.

3. See if it is"Green"Environmental protection products, pay attention to the current ** all kinds of paints and coatings are basically marked"Green"Words. Available on the market at the moment"Green"Building materials are not necessarily environmentally friendly? What kind of product is"Green"Eco-friendly products?

Is it that meeting national standards is equivalent to environmentally friendly products? The confirmation of green products should be confirmed by the Certification and Accreditation Administration of the People's Republic of China, and China Environmental Labels should be recognized when purchasing green home improvement and building materials"Ten rings"icon, which is also the identification"Green products"The easiest and most effective way to authenticity.

4. Look at the weight, don't be sloppy, there are all kinds of paint packaging specifications on the market, in our place, the lightest is 3 kilograms, and the heaviest is kilograms. When you buy, you should pay attention to the fact that there are two kinds of 5 kg, 5 kg gross weight and 5 kg net weight, I think you should be very clear which one to choose!

5. Understand the consumption of paint: consult the merchant about the number of paint brushing times and the painting area, calculate the amount and material cost per square meter, the paint is composed of solids (film-forming substances) and volatiles, the solid content is high to 70% to 80%, and the low is less than 10% to 20%.
