In the decoration, paint is an essential material. However, more and more fashionable today, the paint can also make a big change. Many young people choose to paint themselves and draw a variety of beautiful patterns on the wall. However, in the decoration, how can it be used correctly? The correct use of paint is also an important part of environmental protection.
Little primer big effect
When painting the wall, sometimes we will encounter some minor troubles, such as the upper surface of the paint absorbed too quickly, latex paint components can not brush the predetermined area; soon after the brush appeared discoloration problems, and even paint film loss , Blocks, mildew, often let us helpless.
Originally, no matter the new wall or the old wall in the living room, due to excessive alkalization due to excessive water content, it is even more so in the wet environment, which is the fundamental reason that affects the quality of the paint. Applying a layer of water-based sealing primer before brushing the top coat can not only save the decoration cost, but also has the advantage of being more effective when used in the long-term and decorative effect. The excellent sealing properties of these primers make them effective against the penetration of basic substances in the wall, preventing the precipitation of water-soluble salts and preventing the return of alkali to the walls. At the same time, the good adhesion of the primer makes the wall more smooth, making the topcoat easier to apply and reducing the amount of topcoat used. In this way, the wall surface not only avoids the paint disease, but also helps to maintain the brushing effect for a longer time. In addition, it should be noted that the primer and topcoat should preferably use the same brand or matching paint to prevent chemical reactions between the primer and topcoat. When purchasing, please read carefully the type or type of primer (or topcoat) that is specified in the packaging instructions.
High-quality paint can improve the quality and grade of the entire decoration, giving the home a richer culture and connotation. Buying high-quality environmental protection paints is best done by selecting well-known large-scale building materials stores such as Haomei Building Materials Supermarket and Meimei Home Decoration Plaza.
The paint and putty correctly cooperate to solve the wall cracks and shedding
Despite the use of well-known paints, the walls of the room that had just been renovated were cracked and peeled. What are the reasons? Synthetic resin emulsion interior wall coating, commonly known as interior wall latex paint, it has the advantages of convenient construction, easy renovation, quick drying, scrub resistance, safety and non-toxic, but there are also some paints on the market with poor quality and performance standards; Some construction companies do not regulate the construction of the use of putty but off, these will cause a problem with the quality of the wall.
The current coating problems are:
First, poor quality and performance of medium and low-grade products. The national standard stipulates that the scrubbing resistance index is not less than 200 times. The reason for the product non-conformity is that the company cut corners and materials, uses raw materials with poor quality, and does not strictly carry out inspections.
Second, the quality of products of small companies is unstable. Due to the small scale of production of enterprises, limited investment in technological transformation and technological development, relatively backward production processes, weak corporate management, incomplete quality management systems, and poor product quality stability. Among these enterprises, there are still some companies, ranging from a few people to as many as a dozen people. The factory buildings are poorly equipped, technical strength is weak, and the quality of personnel is low. They do not have inspection methods, let alone quality control, and production has some blindness. Although these enterprises have limited output, they have flooded the market with low-grade, low-quality, low-price, and even fake and shoddy products, resulting in low price competition and similar competition in the market.
The third is that the implementation of standards is not strict, and the inspection and control ability is poor. Some companies do not carry out product batch inspections or do not perform ex-factory inspections in accordance with the express standards, reflecting the company's low level of quality management and the lack of attention to product inspections.
Three types of interior wall paint
The first category is low-grade water-soluble paint. Polyvinyl alcohol is dissolved in water and added with other additives such as pigments. The disadvantage of this coating is that it is not water-resistant and alkali-resistant, and the coating is easily peeled off after being exposed to moisture. It is a low-grade interior wall coating, and is mostly used for interior and interior decoration of middle and low-end living rooms or temporary residences.
The second type is latex paint. It is a water-based medium, and the water resistance and weather resistance of aqueous solutions of acrylic esters, styrene-acrylic ester copolymers, and vinyl acetate polymers are greatly improved compared to the first type, and no traces are left after wet scrubbing. There are different types of decoration, such as flat light and high light, which belong to middle-grade paints. Although the price is more expensive, due to its excellent performance and decorative effect, it occupies an increasing market share.
The third category is the colorful paint that is currently very popular. The film-forming substance of the coating is nitrocellulose, which is dispersed in the water phase in the form of oil-in-water, and can be formed in multiple colors by one spray.
Inner and outer wall latex paints have their own special requirements. The outer wall latex paint is used to paint the building facades. Therefore, one of the most important indicators is anti-ultraviolet radiation. Interior wall paints are used for interior wall paints, and UV resistance is much lower than exterior paints. Interior wall latex paint has high requirements for scrub resistance.
