When decorating, many people may encounter the question of whether interior wall paint and exterior wall paint can be mixed together? Some people, in order to save costs and time, simply apply paint all over the inner and outer walls. This practice is not advisable as it can cause too many consequences over time. Let me tell you the difference between interior wall paint and exterior wall paint.
1. Composition difference:
The interior wall paint is mainly composed of latex, resin, solvents, pigments, etc., which makes it have good adhesion, wear resistance, and covering ability. And exterior wall paint usually contains additives and special resins to cope with changes in the outdoor environment, such as ultraviolet radiation and climate change.
2. Characteristic differences:
Interior wall paint focuses on aesthetics and environmental performance. When used indoors, it usually has a low content of volatile organic compounds (VOCs) and does not bring strong irritating odors to people. Meanwhile, interior wall paint usually has functions such as sound absorption, mold resistance, and antibacterial properties, making it suitable for use on indoor surfaces such as walls and ceilings.
The exterior wall paint focuses on durability and weather resistance. It needs to have stronger UV resistance, weather resistance, pollution resistance, and water resistance to cope with the challenges posed by outdoor environments.
