How to choose high quality coatings and paints

Coatings can be divided into three main types of film-forming materials, secondary film-forming materials, and auxiliary film-forming materials according to the different roles of various parts. The difference in the main film-forming substance determines the type of coating. The main film-forming substance is oil-based paint called paint and acrylic resin-based paint.

In home decoration, the interior wall decoration is the most economical and economical. With the development of the paint industry, interior wall paints used in decoration projects are mostly water-based paints, especially latex paints. Their excellent performance, solvent-free, good air permeability, good texture, and rich color can meet various requirements. Therefore, it is widely used.

First, the purchase of home improvement coatings

Solvent-based coatings form a fine, smooth and tough film with good hardness, gloss and durability. However, the main disadvantages are flammability, solvent volatilization is harmful to the human body, construction requires dry grass, air permeability of the coating is poor, and the price is expensive. This is the paint commonly used for wood finishes in home renovations.

The latex paint, that is, our commonly used latex paint, this paint saves organic solvents compared to paint, it uses water as a diluent, is cheap, non-toxic, non-flammable, and easy to construct.

There are a wide variety of paints on the market, and customers need to refer to some principles when choosing:

First of all, according to the nature of the paint, type, area of ​​use, parts of the building, the construction season and other reasonable choice of paint. For concrete and cement mortar bases, it is necessary to use coatings with good alkali resistance and strong covering power; for wood base materials such as wood flooring products, it is advisable to use polyester coatings with good abrasion resistance and acid and alkali resistance. Wait. In the rainy south, paints with good water resistance and mildew resistance should be used; cold winters should consider coatings with good freeze-thaw resistance; non-alkaline coatings should be used on wood substrates.

Secondly, when considering the economy, it should be the unity of price and durability, the unity of material price and construction price, the unity of material grade and construction level, and the only way to handle the relationship properly is to obtain economic benefits. Reasonable. Instead of unilaterally pursuing low prices, or ignoring the local construction level, blindly pursuing high-grade coatings will not achieve good economic results.

The third is to pay attention to the reasonable function of the paint. In the interface of public areas, paints with good sound absorption, pollution resistance and adhesion should be used. General room can choose fireproof, antifouling, easy to wash paint. Paints for bathrooms and toilets should have water-resistant, anti-corrosion, anti-fouling and easy-scrubbing coatings.

The fourth is to see the reasonableness of decorative effects. Both the texture and the color of the decorative effect are the basic elements of the paint decorative effect. When choosing a coating, consideration should be given to coordination with the room, and there should be a good supplement effect to the indoor body. For rooms with small areas and insufficient lighting, warm colors can be used to create a sense of space expansion.

For example, the gloss of latex paint is generally divided into four types: matt, half-light, medium-light, and high-gloss. The matt gloss and semi-gloss are generally used for the interior wall surfaces of living rooms and bedrooms; the middle gloss is generally used for door and window frames, hanging mirror lines and wear. Larger areas, such as bathrooms, kitchens, etc. High gloss is used for embellishment of door and window frames.

The last step is to understand the technical properties of some coatings when choosing coatings. If you purchase polyurethane paint, you should pay attention to the content of toluene diiso-acid, because its steam is toxic and can irritate the mucous membranes of the eyes. Generally, its content should not exceed 2%.

In most finishing projects, two or more coatings with different functions are used. Therefore, a complete finishing system often consists of three parts. Primer, which is the first coating of the finishing project, can be applied to metal materials as well as internal and external walls. It can seal the substrate, promote and increase the adhesion of the paint on the substrate, and can prevent mold and bacteria.

In the paint, its main role is to improve the adhesion and hiding power, to provide a clean and even surface for the top coat, to increase the thickness of the entire coating engineering system paint film, but also produce a three-dimensional effect on the surface of the object. Topcoat, which is the final coating in the paint system, has perfect decorative features such as color, gloss, and other visual effects, while also protecting the substrate from foreign materials such as ultraviolet light and chemical substances. These three coatings can use the same coating, but also can choose different coatings according to functional requirements.
