What are the classifications of home improvement coatings? How to choose decoration coatings?

Paint is one of the most basic main materials in home improvement, which can be used in many places in home improvement. The quality of paint determines the overall decoration effect and living environment, and even directly affects the health of family members, so the purchase of home decoration paint is very important. So what are the common home improvement coatings? How to choose decoration coatings? Let's take a look together.

What are the classifications of home improvement coatings?

1. According to different parts, paints are mainly divided into wall paint, wood paint and metal paint. Wall topcoat includes exterior wall coating, interior wall coating and topcoat, mainly latex paint and other varieties; Wood paint mainly includes nitrocellulose paint, polyurethane paint, etc., and metal paint is mainly enamel.

2. According to different states, coatings can be divided into waterborne coatings and oily coatings. Latex paint is the main waterborne paint, while nitrocellulose paint and polyurethane paint are mostly oily paints.

3. According to different functions, coatings can be divided into various types: waterproof coatings, fireproof coatings, mildew-proof coatings, mosquito-proof coatings and multifunctional coatings.

4. According to the action form, it can be divided into volatile paint and non-volatile paint.

5. According to the surface effect, it can be divided into transparent paint, translucent paint and opaque paint.

What are the common home improvement coatings?

1. Latex paint: Latex paint is a common name for latex paint. It is made by a certain process with synthetic resin emulsion as the base material, water as the dispersion medium, pigments, fillers (also called bulk pigments) and additives. Latex paint has many advantages different from traditional wall paint, such as easy brushing, quick drying, water resistance and good scrub resistance of paint film. Common latex paints include water-soluble interior latex paints, water-soluble coatings, general latex paints, anti-pollution latex paints, and antibacterial latex paints.

2. Wood coating: Wood coating refers to a resin coating used on wood products, including polyester and polyurethane coatings, which can be divided into water-based coatings and oily coatings according to materials; According to the gloss, it can be divided into high gloss paint, semi-matte paint and matte paint; According to the purpose, it can be divided into furniture paint, floor paint and so on.

3. Waterproof coating: Waterproof coating refers to the coating that can prevent rainwater or groundwater from leaking. It is a one-component water emulsion waterproof coating based on pure acrylic polymer emulsion and other additives. The waterproof film formed after curing of waterproof coating has certain extensibility, elasticity, crack resistance, impermeability and weatherability, which can play a role in waterproofing, seepage prevention and protection.

4. Liquid wallpaper: Liquid wallpaper is a new type of artistic paint, also known as wallpaper paint and wall art paint. It is an environmentally friendly water-based coating that combines the characteristics of wallpaper and latex paint. Liquid wallpaper is made of acrylic emulsion, titanium dioxide, pigment and other additives, and some shells are made by high temperature treatment. Liquid wallpaper is a water-based coating, so it also has many advantages, such as good moisture resistance, antibacterial, insect-proof, aging resistance and so on.

5. Exterior wall coatings: Exterior wall coatings are used to paint the exterior walls of buildings, so the most important indicator is ultraviolet resistance, which requires no discoloration after long-term exposure. Since 20 13, people have paid more and more attention to energy-saving and environmental-friendly liquid stone paint waterborne coatings. Some exterior wall coatings also require water resistance and self-cleaning. The paint film should be hard and flat, and the dirt will come off as soon as it is washed.

How to choose decoration coatings?

1, latex paint purchasing skills:

(1) Look at the packaging: look at the packaging appearance of the product, and look at the barcode, pattern, font, definition, specification and date of the product. Authentic products are basically close to imitations, and most imitations are also very realistic, even made directly from real cans.

(2) Look at the surface: observe the color, luster, average pigment and symmetry of latex paint. Pick up the paint with chopsticks and see the speed at which the paint slides down from chopsticks into the jar. According to the scraping situation, the high-quality latex paint will flow in a fan shape. After a period of time, a thick and elastic oxide film will be formed on the surface of genuine latex paint, which is not easy to crack; The defective products will only form a thin film, which is fragile and spicy.

(3) Look inside: See if the latex paint after opening the cover is consistent with the color clarity marked on your appearance.

(4) Price comparison: there is a gap in the price of latex paint in every region and every store, but the gap should be very small. If the gap is too big, it can basically be determined that the quality is not good, and the merchant can't sell it to you at a loss.

(5) Smell: The moment you open the lid, it is the best time to smell the smell of paint. The truly environmentally friendly latex paint should be water-based, non-toxic and tasteless, so when you smell pungent smell or industrial essence, you can't choose.

(6) Handle: Mix latex paint with chopsticks and touch it with your fingers. Authentic latex paint should feel smooth and delicate. The imitations of inferior paint are mostly like water, leaving them directly, which is not smooth and delicate.

(7) Anti-pollution ability: you can directly brush a little paint on the wall, wait for about 15 minutes, and then scrub the paint surface with a wet rag. Depending on the situation, genuine latex paint has strong scrub resistance, and it will not have a significant impact on the appearance of the coating after being rubbed for one or two hundred times; The low-grade water-soluble paint will fade after rubbing for more than ten times.

2. The main points of buying wood paint:

(1) Look at the packaging: Consumers should carefully check the packaging when buying wood paint. Because polyester paint is volatile, the product packaging should be sealed, and there should be no leakage. Metal packaging should not rust, otherwise it means poor sealing or too long time. Carefully check the production date and shelf life, and first remove the inferior wood paint from the outer packaging.

(2) Look at the brand: When consumers buy wood paint, they should try to choose a reputable regular dealer to buy the corresponding brand of wood paint products. If they find quality problems, they should respond or complain in time, otherwise it is hard to say whether it is the poor quality of wood paint or the construction technology and environmental factors.

(3) Look at the weight: According to insiders, different wood paints have different packaging specifications and different weights. Consumers can know the pros and cons in a simple way when buying: take out each can and shake it. If it is shaking, it means that the weight is insufficient or volatilized.

(4) Look at the quality: Generally speaking, it is not allowed to open the container when buying wood paint, but consumers should carefully check the contents of the paint before unpacking. There should be no crust on the surface of the main paint, and the paint solution should be transparent, uniform in color, free of impurities and have good fluidity; The curing agent shall be a water-white or yellowish transparent liquid, free from delamination and condensation, clear and transparent, and free from impurities; Diluent, scientific name "Tiannashui", commonly known as "banana oil", has clear and transparent appearance, no impurities and good dilutability.

(5) See the construction effect: After the high-quality wood paint is prepared in strict accordance with the requirements of the specification, it should have delicate feel, uniform luster, uniform color, suitable viscosity, good construction tolerance and good construction effect.

3, waterproof coating selection method:

(1) Long durability: waterproof parts such as indoor toilets and kitchens have high humidity, many pipes, great leakage risks and high rework costs, so waterproof coatings with permanent leakage-proof, seepage-proof and moisture-proof effects should be preferred.

(2) Environmental protection: non-toxic, tasteless and pollution-free are the basic requirements for indoor waterproof materials. Waterproof coatings with strong odor are highly toxic and will volatilize carcinogens such as benzopyrene for a long time, so don't use them for indoor waterproofing.

(3) No corrosion: select waterproof coating with neutral PH value to avoid acid return, alkali return, cracking and corrosion of metal parts in the waterproof layer after construction.

(4) Convenient construction: Waterproof construction of interior decoration is mostly completed by ordinary Plaster workers. The simpler the construction, the more waterproof coating can ensure the quality of waterproof construction.

(5) Reliability: choose the best from the best. Choose brand products with high popularity, good reputation, high anti-counterfeiting degree and international quality system certification, and don't give "crooked" goods an opportunity.

4, liquid wallpaper purchase knowledge:

(1) Look at the color: A major feature of liquid wallpaper lies in its pearlescent color and metal refraction effect. This kind of luster and brightness can make the pattern look lifelike, so when you buy liquid wallpaper, you need to look at its coating effect first to ensure its bright and vivid color.

(2) Smell: The material of liquid wallpaper is relatively natural, and there is no obvious pungent smell and oily smell. Most of them only give off a faint smell of substances. If a few people can smell a certain smell, it belongs to the spice added in the later stage to improve the sensory quality of the product, which has nothing to do with the quality of the product itself.

(3) Look at viscosity: With proper ready mixed paint, there will be no impurities and particles floating up after uniform mixing, and the shape of the material will not be too thin or too thick. You can also try to stir the raw materials with clear water. Good quality coatings are relatively independent and clearly visible in clean water, and will not make water turbid.

(4) Look at floating objects: Good quality liquid wallpaper usually has no floating objects on the surface of protective glue. If a large number of floating objects or even colored particles have accumulated to a certain thickness on the surface of raw materials, it proves that the paint has certain quality problems.

5, exterior wall coating procurement strategy:

(1) Look at quality: enduring brands are trustworthy. Fichter brand exterior wall coating has low VOC, which has been well received by consumers since its listing. Over the years, we have won the bid for many major construction projects, and the accumulated word of mouth can explain the quality of a paint.

(2) Look at the function: Inferior paint will cause immeasurable harm to the environment and human body. Environmental-friendly exterior wall coating can not only decorate the exterior wall, but also protect it. With the development of science and technology, such as the appearance of heat insulation coatings and new coatings, the air in urban smog has been purified and our living environment has been optimized.

(3) Look at the color: the color of the paint is not only the interior decoration, but also the exterior wall paint. The color selection of the external wall of the building should conform to the architectural style and the surrounding environment to avoid light pollution. Paints with rich color structure are more popular.
