2. 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 defective paint will only form a thin film, which is fragile and has a pungent smell.
3. Mix the emulsion paint with a wooden stick, and then pick it up with a wooden stick. When the emulsion paint flows down, it will become a fan.
4. Touch with your fingers. Authentic latex paint should feel smooth and delicate.
5. When the emulsion paint is brushed on the wall and wiped with a wet cloth, the color of the authentic product is as bright as new, while the inferior product will fade with a gentle wipe because of poor condensation and water resistance.
6. When purchasing, check the composition. The composition of the paint should be copolymerized resin or pure acrylic resin.
7. Don't forget to check the shelf life of the product.
Although latex paint has many advantages such as convenient construction, strong hiding power, rich colors, scrub resistance, strong environmental protection, etc., it also has some common quality problems, and poor treatment will affect the decoration quality.
