All construction coatings have passed ISO9001 Paint Home News: the bedroom wall is the largest indoor area, but also the focus of home decoration Among many wall decoration materials, various latex paints are the most widely used So how to choose the best latex paint for your home? The classification of emulsion paint emulsion paint is a kind of wall paint, which is made of water as medium, acrylate and other aqueous solutions as film-forming substances, adding a variety of auxiliary components Latex paint is a water-borne coating, it is mainly composed of five components: one is water; the two is latex, is a kind of similar white glue things, play the role of adhesion, as the core component of latex paint; three is pigment; four is filler; five is additives, such as anti foaming, anti freezing The main cost of latex paint consists of the second and the third According to the parts used, there are two main types of emulsion paint: exterior wall paint and interior wall paint, but they are all water-based According to luster, it can be divided into low light, half light, high light and other varieties Among them, the film-forming substance of the interior wall latex paint is insoluble in water, the water resistance of the film is high, and there is no trace left after wet scrubbing The basic performance of the exterior wall emulsion paint is similar to that of the interior wall emulsion paint, but the paint film is hard and has stronger water resistance It can also be used in places with high humidity such as toilets ★ tips: the higher the price, the better When choosing latex paint, good cost performance should be taken as the standard, and the corresponding characteristic latex paint should be selected according to the different functions of the room For example, the best choice for toilets and basements is the ones with good mildew resistance, the ones for kitchens and bathrooms are the ones with good stain resistance and scrub resistance, and the ones with certain elasticity are the ones for covering cracks and protecting wall decoration Due to the close relationship and even mutual restriction between various properties of coating products, the single performance may not be prominent for the multi-functional products popular in the market, but the comprehensive performance is generally good Characteristics of emulsion paint (1) fast drying of coating At 25 ° C, the surface can be dried within 30 minutes and completely dried within 120 minutes (2) Good light and color retention Hard film, smooth surface, comfortable appearance (3) Convenient for construction and modulation It can be constructed on the newly constructed wet wall (4) It is safe, nontoxic and does not pollute the environment (5) No fire hazard As the coating is water based, there is no risk of fire (6) The wall is not easy to absorb dust after use (7) Good alkali resistance It can be applied to alkaline newly plastered walls, ceilings and concrete walls without back adhesion and discoloration The quality of latex paint is mainly determined by the quality of latex However, latex paint for household use shall be applied in strict accordance with the construction method After five years of good quality, the adhesion of the emulsion will also fail, and the adhesion of the latex will be invalid for ten years Generally do latex paint will not tell you these situations, so consumers do not think that latex paint is once and for all The purchase of latex paint should be based on their own needs to choose the right type of paint, do not blindly pursue "advanced" or cheap To know that the quality of coating is related to the physical and mental health of residents, we should choose high-quality coatings that meet the national standard (GB) High quality coating has strong adhesion, good antifouling property, and is not easy to turn yellow, and it will be stronger and more durable than ordinary coating, so high quality coating can maintain the best appearance effect for a longer time Inspection points: (1) first look: see if the paint has settlement and caking After a period of time, the surface of the genuine latex paint will form a thick, elastic oxide film, which is not easy to crack; while the inferior product will only form a very thin film, which is fragile and has a pungent smell (2) Second, smell: smell the paint for odor and irritant smell The real environmental protection latex paint should be water-based, non-toxic and tasteless (3) Third wipe: brush a little paint on the cement wall, and wipe with a wet cloth after the coating is dry One or two hundred times rubbing of real latex paint will not have a significant impact on the coating, while only a dozen times rubbing of low-grade water-soluble paint will cause the fading phenomenon of powder loss and exposed bottom (4) Four touch: mix the emulsion paint with a wooden stick and pick it up with a wooden stick When the high-quality emulsion paint flows down, it will form a fan shape Touch with your fingers, the genuine latex paint should feel smooth and delicate ★ tips: visit more building materials supermarkets when you have time to learn the latest coating market Buy more before holidays Many stores or manufacturers will choose to do promotions or launch new products before holidays Choose the right time, you can buy both cheap and satisfactory emulsion paint DIY painting tools and methods now more and more families like their DIY rooms, and try the process of "changing the old look into a new one" by themselves Then, pay attention to the following points when painting DIY There are three general brush tools: brush, roller and spray gun Correspondingly, there are three common methods: brush, roll and spray The painting sequence starts from the ceiling, then walls, doors and windows, and finally skirting boards, mullions, etc Brush painting: the most primitive, the simplest and the most common The advantages are fuel saving, suitable for a variety of shapes and paint varieties The disadvantage is low efficiency, not suitable for fast drying paint If the operation is not skilled, the paint film will produce brush marks, sagging and uneven painting Roll coating method: it is suitable for large-area construction with high efficiency, but its decoration performance is slightly poor Choose a roller with the appropriate length of bristle to avoid coating accumulation at the end of the roller From the edge of the * ceiling, roll up in the "m" or "W" shape to reduce splashing After each painting, do not leave the wall to obtain even and parallel paint film Spraying method: it is suitable for painting high brightness paint, because if the above two methods are used, it is easy to leave traces and produce uneven color effect No matter what kind of painting method, we must pay attention to the use of primer, both to protect the wall and save money The primer can make the base material porosity uniform, improve the coating rate of the top coat, and save the top coat The primer is much cheaper than the top coat, so it costs less Secondly, a brush of primer can help the top coat to improve the fullness of the paint film, making people feel full of color and texture ★ tips (1) after the paint is bought, the dilution must be appropriate To get an ideal paint film, about 15% - 20%, see the manual for details (2) After brushing, remember to thoroughly clean the tools with clean water, so as to ensure repeated use Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
