Decorating a house requires painting not only the interior wall, but also the exterior wall. However, with the continuous research and development of building materials and the increase of brands, consumers do not know what kind of paint to choose. So today, Xiaobian will introduce to you the types of exterior wall paint and what to pay attention to in the construction of exterior wall paint

when decorating a house, not only the interior wall needs to be painted, but also the exterior wall needs to be painted. However, with the continuous development of building materials and the increase of brands, consumers do not know what kind of paint to choose. Therefore, today's editor will introduce to you the types of exterior wall paint and what to pay attention to when constructing exterior wall paint

introduction to the types of exterior wall coatings 1. Wall paint

the main materials of wall paint are film substances fused by polymers such as acrylate and vinyl acetate, in which a variety of auxiliary components are added. Because its film will not dissolve in water, the water resistance and weather resistance of the film are greatly improved. Even wet wiping will not leave any traces, but the color of this kind of paint will be relatively small

introduction to the types of exterior wall coatings 2. Colorful coating

colorful coating is the most popular exterior wall coating at present. Its main substance is nitrocellulose, which is dispersed in the water phase in the form of oil in water. As long as it is sprayed once, it can form a variety of color stripes. Because it is mostly used to imitate stone effects, it is also called liquid stone, also known as horizon exterior wall coating

Introduction to the types of exterior wall coatings 3. Pseudo porcelain coating

pseudo porcelain coating is a popular coating in recent years. Its main material is solvent resin. The paint film formed by it is not only very shiny, but also solid and full. It looks like porcelain glaze. It has very good water resistance, alkali resistance, wear resistance and aging resistance, and its adhesion to the wall is very strong

what should be paid attention to during the construction of exterior wall coating:

1. The influence of construction temperature

during the construction of exterior wall coating, the temperature must be more than 5 degrees Celsius before construction, and a small number of requirements are more than 10 degrees Celsius. Therefore, if the construction is carried out in cold winter, the construction requirements of exterior wall coating can be met only during the period of the highest temperature at noon, but because of the temperature difference between morning and evening, Therefore, the staff must pay attention to adjusting the construction time to avoid bad coating film formation

2. Impact of construction humidity

because the impact of construction humidity on the construction of exterior wall coating is not particularly large, it is often ignored by many construction teams. In fact, when the humidity is greater than 85% or the wall is still wet after raining, construction is not allowed

3. Influence of bottom layer treatment

in addition to the construction humidity is not paid attention to, bottom layer treatment is also a problem that is often ignored. The most common problem is the use of low-strength putty, resulting in the quality of the whole coating being affected and damaged

summary of the editor: the above is all about the introduction of the types of exterior wall coatings and what should be paid attention to in the construction of exterior wall coatings shared by the editor. The greatest function of exterior wall coating is to protect the wall from damage caused by sunlight and rain erosion
