According to the scope of our home decoration life, our common paint has three major areas: wall paint, wood paint, metal paint.
Wall paint
Wall paints include exterior paints, interior wall paints and nuclear top coats, mainly latex paints and other varieties. The paint that we paint on the interior walls is the interior wall paint. It can be divided into water-soluble paints and latex paints. The general decoration is latex paint. The latex paint is made of water as a diluent, which is a kind of lacquer that is easy to use, safe, washable, and has good air permeability. It can mix different colors according to different color schemes. The ingredients are basically made up of water, pigments, emulsions, fillers and various additives. These raw materials are not toxic. Exterior latex paints and interior latex paints have similar performance.
At present, the so-called "latex paint" that contains a large amount of formaldehyde in the market is actually a water-soluble paint, not a latex paint. Some unscrupulous manufacturers use inferior water-soluble paint to paint latex paint. Therefore, choosing the right goods and maintaining ventilation is an effective way to prevent pollution.

If possible, ask the seller to open the paint bucket and test it in person.

2. If the product has serious stratification, it indicates that the quality is poor;
3. After gently stirring with a stick, the paint stays on the stick for a long time and covers evenly, indicating good quality.

Wood paint
Wood lacquer is mainly lacquer, polyurethane paint, etc. It is very common in furniture and flooring. According to the gloss can be divided into light (high light), semi-matte, matte effect, as well as water and oily points.
Water-based paint is based on clear water as the only thinner, does not contain benzene, formaldehyde and other toxic substances, is the country's designated environmental protection paint. Oil paint, also known as oil paint, with dry oil as the main coating material of a class of paint, mainly clear oil, thick paint, oil blending paint, oil anti-rust paint and putty, putty and so on. The oils used are mainly tung oil, linseed oil, eucalyptus oil, soybean oil, sunflower oil, fish oil, etc. It is characterized by easy production, low cost, good brushing, flexible coating, and good permeability. The disadvantages are slow drying and poor film physical properties. Most of them have been replaced by synthetic resin paints with excellent properties.
In addition there are some special furniture and flooring instead of paint, but the use of pure vegetable oil or waxing technology, such as mahogany furniture is usually waxing can also ensure the furniture surface gloss and oxidation resistance, some doors and windows use environmental tung oil, some Children's furniture brands use pure vegetable oils.
Metallic paint
Metallic paints are mainly enamel paints. When we buy furniture, we usually paint metal, and we often cannot distinguish between piano paints. Piano paint is common in panel furniture and cabinets, with high gloss, special compactness, and excellent scratch resistance. Metal paint is often used in the machinery industry.
Advantages and disadvantages: beautiful colors, excellent water resistance, but general wear resistance and high temperature resistance.
TIPS: Another kind of so-called “piano lacquer†is actually only a layer of bright varnish sprayed on PVC. The cost is negligible and the durability is extremely poor. In addition to "bright," it is not sticky to the piano paint.
