Wall primer is applied in different fields, and the process methods and purposes for polishing tiles also differ. Common wall primer treatment and modification of object interfaces can be divided into four process types: wetting and impregnation, coating treatment, coupling agent treatment, and surface modification. Wall primer is applied in the construction field, including concrete interface agents, tile interface treatment agents, building insulation panel interface treatment agents, etc.

What should be paid attention to when purchasing?

1. The color of wall primer products. The natural color of wall primer products is milky white. One disadvantage is that after the wall is primed, the marks are not aesthetically pleasing to the eyes, and the primed wall looks the same as an unprimed wall. So now most wall primers have color. However, it is not true that the darker the color, the higher the product quality. The variety of colors creates differences in people's choices, leading us to select the wrong product. Currently, the colors of wall primers on the market are yellow or blue.

2. Thicker wall primer is not necessarily better. Many manufacturers advertise how thick their products are and how good their adhesion is. But it is not true that thicker is better. The adhesion strength can only be obtained based on the actual parameters of the product and cannot be simply judged by viscosity. Some unscrupulous manufacturers add thickeners to wall primer, but the actual bonding effect is not good.

3. During construction, pay attention to the thickness of the wall primer and the timing of brushing it on the wall. According to the instruction manual, wall primer can be brushed 1-2 times, and it does not need to be brushed very thickly. When brushing wall primer on the wall, it should not be done too early. Some construction personnel brush the wall primer as soon as they enter the site, and then proceed with the electrical and plumbing work. The correct method is to first complete the electrical and plumbing work, and then prime the wall before leveling it.
