The uneven color of the base layer and the lack of treatment can result in uneven coating color, which must be covered by applying putty or brushing a primer. Consumers can choose coatings with strong coverage, dilute and apply them according to the prescribed ratio, which can also avoid uneven color; In addition, when selecting interior and exterior wall paint manufacturers, it is important to choose products from the same manufacturer, variety, and batch number, otherwise color differences may occur.

There are various reasons for such problems: for example, the base layer is not treated flat and clean, the brushes used have sand particles, debris, or the operating environment is not clean, dust and dirt fall on the newly applied paint, etc.

Avoidance measures include: the base layer must be cleaned and leveled, and putty powder must be applied as required, and sandpaper must be used to polish it flat. Used brushes must be cleaned in a timely manner, carefully inspected, and the environment of the interior and exterior wall coating manufacturers should be well protected against dust during construction.

If the base layer is too smooth, or has oil stains and dust, it is easy for the coating to not adhere firmly and produce peeling phenomenon; In addition, the putty is not firmly bonded, and the coating adhesive is strong, forming a "crispy on the outside and tender on the inside" state. In the case of large temperature differences or uneven humidity, the surface of the coating is also prone to cracking and peeling. Preventive measures include: using steel wire to brush and clean the smooth substrate, using solvents to remove oil stains, and rinsing with clean water; When applying primer, choose products that match the topcoat; The coating should not be too thick, based on the principle of being able to cover the base layer without penetrating, the coating should be full and uniform, and the color should be consistent; Select different putty according to different base layers, so that the bonding strength of putty and the bonding strength of coating can adapt to each other. In addition, during construction, it should be noted that the base layer must be dry before painting, and the areas that do not require painting and the painted areas should be protected in a timely manner.

Nowadays, homeowners generally use latex paint for wall decoration, and the quality of latex paint coating directly affects the painting effect of the wall. Before purchasing latex paint coating, we should first understand the method of identifying the quality of latex paint coating. Next, we will explain to the majority of homeowners which type of coating is used for wall refreshing. We will introduce five aspects of coating, including leveling performance, construction performance, covering ability, PVC height discrimination, and scrub resistance.

Environmental performance is currently the most concerned issue for consumers around the world. Chinese consumers pay attention to environmental protection and health in all aspects of their lives. Judging from the most environmentally friendly and cost-effective wall renovation latex paint on the market, its main parameters are far below the Chinese national standard. The heavy metal content is only 2% of the national standard, and VOCs (volatile organic compounds) are not detected. Choosing such latex paint is the only way to live with peace of mind.

Use a wooden stick or spoon to stir the paint evenly, then lift the spoon to a high place and observe the posture of the paint flowing down. If it falls in blocks, the leveling performance is poor. If the paint flows in a linear pattern, it indicates that the paint has certain leveling performance. Secondly, mix the paint with water according to the ratio specified in the construction manual, and apply it onto the non absorbent surface with a hard bristled brush. After it dries, the smoother the surface of the coating, the better its leveling performance. In this regard, the original imported latex paint used for the renovation of Feima wall is made very well, with a viscous texture and excellent leveling performance, which can be regarded as the first in the industry.
