Latex paint, also known as cement paint, has its advantages: at present, latex paint on the market is water-based, and water-based paint is liquid paint with water as diluent. The biggest difference between water-based paint and traditional oily paint is that water-based paint does not need to add any curing agent and diluent, but only needs to be mixed with water, so it does not contain harmful substances such as formaldehyde, benzene and xylene, thus eliminating the possibility of air pollution. At present, it has basically replaced oily paint in developed countries such as Europe and America, and the permeability has reached over 90%. This is an environmentally friendly coating. Disadvantages of latex paint: single color, no visual effect of wallpaper and liquid wallpaper. Advantages of wallpaper: visual comfort, soft touch, diverse colors, rich patterns, diverse styles, rich artistry, and can create different life styles and tastes at will. Compared with ordinary decorative materials such as latex paint, wallpaper expresses richer emotional information through patterns, textures, colors and techniques, which can better reflect the owner's taste and preferences. Disadvantages of wallpaper: the service life is not long, the edge will become warped where there are seams, and the moisture-proof performance is not very good. Ordinary wallpaper requires higher humidity on the walls and indoors. Ordinary wallpaper is not very breathable, so it is difficult to give off the smell of glue (high-grade wallpaper with good glue will be much better, but you have to pay for it). Good wallpaper costs more. Advantages of liquid wallpaper: rich colors, diverse patterns, strong personalization, strong visual effects, many styles, artistic, and can create different living styles and tastes at will. Environmental protection performance is the same as latex paint. Because it is deepened on the basis of latex paint, its service life is the same as latex paint. Because it is a water-based paint, it has good moisture-proof and antibacterial properties, and is not easy to be moth-eaten and aging. The transformation is convenient and the cost is not high. Disadvantages of liquid wallpaper: liquid wallpaper is also a kind of water-based paint, but it depends on the effect of wallpaper made by decoration workers on the spot. So it needs to put forward certain requirements for technology, and not everyone can operate the construction. The effect is directly related to the master's technology, construction quality control and color matching, so it needs the training and support of certain manufacturers.
