When we buy a wall paint, we should not be too persistent, such as scrub resistance, and it is not necessary to pursue it excessively, because it does not have much practical significance. Instead, it should pay attention to the actual basic performance of the paint.
Now people's requirements for latex paint are no longer limited to decorative, but also emphasis on functionality, so when purchasing, the function of latex paint is very important, according to different parts of the brush to choose latex paint. For example, latex paints used on the walls of bedrooms and living rooms require strong adhesion, delicate texture, good resistance to differentiation and air permeability, and latex paints for kitchens and bathrooms should be waterproof, mold-proof and easy to wash.
Inferior emulsion paint not only affects the construction quality, but also contains unqualified chemical raw materials that can harm human health. They should try to purchase them from specialty stores or special dealer stores. When purchasing, check the product's packaging, appearance and intrinsic quality.
1. After the lid is opened, the truly environmentally-friendly emulsion paint should be water-based, non-toxic and odorless, so if the latex paint has a pungent odor or industrial flavor when it is smelling, it is not an ideal choice.
2. After a period of time, the surface of genuine latex paint will form a very thick and elastic oxide film, which will not be easily cracked. The inferior product will only form a very thin film, which is fragile and has a spicy smell.
3. Mix the latex paint with a wooden stick and pick it up with a wooden stick. The high-quality latex paint will become fan-shaped when going down the drain.
4. Touch with your finger, genuine latex paint should feel smooth and delicate.
5. The latex paint is applied to the wall and wiped with a damp cloth. The genuine color is bright as new, and the defective product will fade due to poor condensation and water resistance.
6. Look at the ingredients when purchasing. The composition of a good quality coating should be a copolymer resin or a pure acrylic resin.
7. Don't forget to look at the product's shelf life.
Although latex paint has many advantages such as convenient construction, strong hiding power, rich colors, scrub resistance, and strong environmental protection, it also has some common problems of quality, and poor handling will affect the quality of decoration.
