Please let someone who knows about paint tell me! Thank you!

Let's talk about the concept of paint first!

Paint is a general term, as the name suggests, it is used to paint, it includes wall paint, wood paint, glue, etc.

Wood paint is paint, and it is divided into two categories, one is clear water paint and the other is muddy water paint. Clear water paint is the kind of transparent paint, which can be divided into three categories, polyester paint, resin paint and blended paint. Nowadays, home decoration is mainly based on polyester paint, and the latter two are mostly used for brushing railings or something.

Both polyester paint and resin paint require the curing agent to dry faster, and the blending paint can be directly coated and dried more slowly. Muddy water paint is colored paint, which is also divided into the above three categories.

There is not much distinction between wall paints. Now it is the hardest of the two brands, Duoshi and Nippon. Hope it helps.

It is recommended to make a first-line brand first = after getting started, and then make a second-line brand, so that there is a combination of high and low There are both word-of-mouth products (first-line brands) and products that make profits (second-line products). As for the first-line brands, you can check them, such as Nippon, Dulux, Laiwei, China Resources, Carberry, Bauhinia, etc. Tips: The 2 brands that the friends above said are estimated to be Wang Po selling melons and boasting Haha, especially the red apples, a typical 3-line brand, ** company, we have a new entry into the industry, was fooled by this factory, and the first 500,000 was sold as a result, and there is a warehouse after a year and a half, haha, I met people in the market all day long and asked others to help deal with it (we are a small prefecture-level city).

It is no exaggeration to say that paint is the most popular wall material for home decoration, paint can make our walls colorful, so the owners will consider paint when decorating, but the choice of paint is related to the decoration effect and environmental health, therefore, it is also very important in the purchase of paint, so how to choose paint?

Clause. First, see if the color style matches.

Before buying paint, you should first consider whether the paint matches the color style of the floor, curtains, etc. Since the area of the color card is small, it will become darker after being painted on the wall, so it is advisable to pay attention to the color selection. The color on the color card may be slightly different from the substance, and the substance shall prevail.

Clause. Second, it is best to choose the paint adjusted by the machine.

Many people like to paint their own walls, but the effect may not be ideal. It's best to use ready-to-use machine-adjusted colors, with thousands 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 the order is booked before purchase, or the tinting is available for pick-up in time, and the price of the tinted paint will be slightly expensive.

Clause. 3. Choose paint according to the climate.

In the humid weather in the south, the choice of paint should be mainly moisture-proof and mildew-proof, and it is best to choose latex paint with enhanced anti-mildew effect to avoid mildew and blistering on the wall.

Clause. Fourth, the details that need to be paid attention to when purchasing.

1. Buy the heaviest paint, if the oil drum is going to get up and there is a sparse noise, it means that the packaging is seriously insufficient, and the viscosity is too low;

2. Buy the least consumption, the unit is low, the consumption is often very large, the calculation is more expensive and the cost is more prodigal, and the quality effect is poor.

3. The professional matching of the Mai's hole wheel is strong, and it can provide technical guidance and after-sales service and colorful model color cards; In particular, the environmental protection label on the main paint packaging needs to recognize the "ten rings" icon of China's environmental label, which is also the easiest and most effective way to identify the authenticity of "green products".

What's the difference between PU and PE? 2009-07-28 10:20What is PU paint? What is polyester paint?

Polyester paint is commonly known as "piano paint" inside and outside the industry.

Polyurethane paint is also paint, and polyester paint is only one word difference, but there is a difference of several grades: the volatile organic compounds (that is, the VOC that people talk about tiger discoloration) of polyurethane paint are several times that of polyester paint, which has a strong negative effect on human health.

China needs to use nearly 500,000 tons of various paints every year, of which "polyurethane paint" accounts for eighty percent, and 80 of this part of the mainstream paint have fraudulently used the name of "polyester paint" to enter the market, this kind of polyurethane paint from Guangdong began to call polyester paint practice, in three or four years to develop rapidly. The "habit" has rapidly spread from Guangdong to the whole country, and so far more than 80 enterprises across the country have "slipped away".

The market retail price of polyester paint per kilogram is about 60 80 yuan, while the market retail price of polyurethane paint per kilogram is about 20 35 yuan.

In order to distinguish the products, the industry association marked the product certificate of polyester paint with PE, and the product certificate of polyurethane paint with PU. === At the same time, we can also see the difference between the two paints: unsaturated resin paint, also called polyester paint (PE), its advantages:

1. It has a very good hardness, which can reach more than 3h 2, the topcoat can make a high gloss 3, wear-resistant, acid-alkali resistance, and good heat resistance 4. The fullness is very high and its shortcomings: 1. The operability is more complex because it needs to add initiators and accelerators to play a curing role. The amount of initiator and accelerator should be changed according to the change of temperature and humidity.

In addition, the initiator and accelerator cannot be transferred into the paint at the same time, otherwise it is easy to cause disasters and accidents. There are strict requirements when it comes to blending paints. 2. The active period of the adjusted paint is very short, and the adjusted paint must be used up within 25 minutes.

3. At present, PE topcoat only has bright products, no matte products. Polyurethane coatings are commonly known as polyester paints (PU) Its advantages: 1. Fullness, hardness, and transparency have excellent performance 2. Good stable performance and high product stability 3. It can be combined with other paint varieties to make different performance effects It is a paint with excellent comprehensive performance.

It is also the most widely used. Its disadvantages: 1. The workability is worse than NC paint 2. The fullness and hardness are worse than the common processes of PE paint

1. PU bottom, PU surface: the most common process 2. PE bottom, PU surface: show high fullness, strong anti-sagging, suitable for high-end furniture production 3, PU bottom, NC surface:

Good fullness, fast construction 4, UV bottom, PU surface: the most promising process, extremely high efficiency, excellent product quality 5, PU bottom, W surface: have a certain fullness, strong environmental protection Common construction methods:

1. Spraying (hand spraying, computer spraying) 2. Primer roller coating (not commonly used) 3. Spraying (bottom and surface).

For cracked and cracked parts, you can buy the kind of bagged putty, try to choose ***, this is very cheap.

Clean up the cracks first, remove the hairs and ties at the cracks, and after processing, use the scraper to scrape the wall, smear the cracks, and then try to level the previous wall, if there are depressions in the cracks, then wait for the first putty to scrape and dry, and then scrape the second time, pay attention not to be too thick each time, do not fill it all at once in order to save trouble, which will cause the next cracking. In this way, until it is leveled with the surrounding wall, the putty surface is burred and sanded, and then you can apply the matte latex paint you said.

Considering that the latex paint you used to brush has been for several years, it is estimated that there must be a difference with the color you bought newly, it is recommended to be careful and regular when brushing, considering the current weather, under normal circumstances, the first time it dries quickly, and then the second time after drying, it should be no problem.

The cracks at the gypsum line are not easy to use a scraper, you can roughly wipe them with your fingers, follow the above steps, and finally brush the latex paint.

Personally, I suggest that you don't do it yourself, because you are still unprofessional, which involves the problem of grinding and paint color matching, etc., don't get more and more ugly in order to save these few dollars, and the more worrying you are! It is recommended that you go to an oiler master! Hope it can help you...

I think it's better to find a decoration company to get it, and it's time-consuming and laborious to get it yourself, and it's also troublesome to get unsatisfied.

I am a decoration company. Material needed for wood cracking: instant adhesive.

It is used to deal with cracks. It is not recommended to use plaster treatment, which is prone to re-cracking. No. fine sandpaper.

It is used to polish the paint and unevenness of the surface of wood. The original smooth surface must be polished roughly. 3.

Brush with white primer. It is used to cover surfaces that are not smooth or uneven. Do not apply the topcoat directly.

Otherwise, the surface will be uneven. 4. Brush the topcoat. Dry.

Wall and gypsum line treatment: 1. Hang the original putty from the cracked place, and the most suitable width for hanging is 4 cm, and the length is determined according to the length of the crack. 2：

Prepare the kraft paper belt, white latex, first brush the white latex to the cracks. Then stick the white latex brown paper to the cracks. 3. Use putty to fill the 4 cm recess that has been hung up.

Allow to dry and sand, then brush with latex paint. Get.

I wrote it myself, you first go buy a snatching knife, snatch some cracks, and then scrape the plaster, patch it with a bandage, and then scrape the white, and the sand is polished with latex paint

It is best to use latex paint, please ask professional people to help you pick and construct, it is best to use imported good latex paint, which is not only environmentally friendly but also very healthy! ~

For users with high environmental protection requirements, you can refer to it.

1 High profit: Nippon Paint = (Japanese Paint) China Resources Paint [30% rebate, low cost performance] 2 High rebate: Nippon Paint = (Japanese Paint) China Resources Paint [30% rebate, low cost performance before the draft] 3 Yi Shijing Socks Worker: Nippon Paint = (Japanese Paint) Laiwei Paint.

4. Good effect: Laiwei lacquer, master lacquer, Dulux.

5 high reputation: Nippon Paint = (Japanese varnish) Dulux.

6. High environmental protection: Laiwei Paint, Sherwin-Williams Paint (can protect your workers and family), 7. Small taste: Sherwin-Williams Paint, Laiwei Paint, Dufang Paint, Master Paint, Mowell, Dulux.

I do the renovation. Basically, Nippon Paint and China Resources are used. Dulux. The effect is pretty much the same. It's hard to say anything else.

The best brands: American master paint, ordinary brands, Nippon, Dole Pops, Carberry, Purple Golden, Low-end products, and other not well-known socks.

Also note that the current paint is polyester paint, I don't know if you used to use nitro paint, the two kinds of paint can not be mixed with good knowledge, please decorator to help you confirm before buying.

Nippon Paint and Dulux are good

One look: the outer packaging and environmental protection test report will be marked on the front of the general latex paint with the name, trademark, net content, ingredients, use methods and precautions. Pay attention to the production date and shelf life, the shelf life of each brand of latex paint varies from 1 to 5 years, and buy products that have been produced recently as much as possible.

Now the general brand latex paint has an environmental protection test report or test sheet. Consumers can have a detailed understanding of the environmental performance of latex paint by reading the test sheet clearly. The test report has standards for the test results of free formaldehyde and heavy metal content.

The national standard of free formaldehyde cannot exceed grams per kilogram.

Second: Generally speaking, the quality of latex paint is about 7 kilograms, a barrel of 5 liters; A large barrel of 18 liters is about 25 kilograms. There is also a simple way to lift the paint bucket, the regular brand latex paint shaking generally can not hear the sound, if it is easy to shake the sound, it proves that the latex paint viscosity is insufficient.

Three-hands: open the can to test the high-quality latex paint is relatively viscous, milky white liquid, no hard lumps, uniform state after stirring, and no peculiar smell. Otherwise, it means that the latex paint has quality problems.

In addition, it can be applied evenly on the fingers, and if the conjunctiva dries within a few minutes and the conjunctiva has a certain degree of ductility, it is a safe coating.

Paint is a colloidal solution. It is applied to the surface of the object, and after a period of physical and chemical changes, a tough and continuous film that is firmly bonded to the surface of the coated object is formed to achieve its protective function, decorative function and other special functions. According to the different film-forming substances, coatings can be divided into:

Oil-based paint, which is based on dry oil, added pigments and various additives. Commonly used paints are oil-based paints. Including organic polymer coatings, inorganic polymer coatings, composite coatings.

According to the different dispersion media of coatings, coatings can be divided into: solvent-based coatings, with organic polymer synthetic resin as the main film-forming substance, organic solvent as the dispersion medium (diluent), and added pigments, fillers and additives. Water-soluble coatings are made of water-soluble synthetic resin as film-forming substance, water as diluent, and appropriate pigments, fillers and additives.

Emulsion-based paints, i.e. various latex paints, are very fine synthetic resin microparticles that are dispersed in water by the action of emulsifiers and made with appropriate pigments, fillers and additives. According to the scope of application, coatings can be divided into: interior wall and ceiling coatings, exterior wall coatings, and floor coatings.

According to the thickness and texture of the coating layer, the coating can be divided into: thin coating, water-based thin coating, synthetic emulsion coating. Thick paint:

There are synthetic emulsion thick coatings, synthetic resin sand wall coatings. Multi-layered architectural coatings, including cement-based laminated coatings and synthetic resin emulsion-based laminated coatings.
