Paint knowledge: what are the disadvantages of Chenyang water paint

Core tip: do you know about waterborne paint? Water based paint is different from ordinary paint It has little pollution to the environment, and because it uses water as the diluent, it does not contain toxicity and taste It is in line with modern people's concept of environmental protection, so it is highly praised by people Let's use a brand to learn about the shortcomings of Chenyang water-based paint, let's have a look Hebei Chenyang industry and Trade Group Co., Ltd is a modern group company integrating water paint production, e-commerce, housekeeping, building materials trade and engineering construction It is located in Chenyang street, Xushui, the hinterland of Beijing Tianjin stone economic golden triangle, Paint knowledge | precautions for wall paint color selection Recommended introduction: when painting the wall, the owner sometimes has difficulty in choosing what color of the wall paint to paint In fact, there is no ugly color in the wall paint, only the disharmonious color matching The use of wall color contains the knowledge of health Too strong color will stimulate people's perception, make people have a sense of fidgety, affect people's mental health Grasp the basic principles of wall color and paint a colorful space 1、 Wall paint color selection notice 1 Light color is generally used for the top surface Light colors make people feel light, dark colors make people feel heavy Usually, the treatment of rooms is from top to bottom, from shallow to deep For example, the ceiling and walls of rooms are white and Paint Home News: do you know about waterborne paint?
