Ms. Xue's home was completed and completed, and her friends and relatives received favorable comments. He called the newspaper and invited the reporter to visit. She told reporters that although her home was just a few days old, there was no "decoration" in the house, because the wall was painted with an exterior paint. According to the reporter’s understanding, “decoration taste†is mostly the taste of free formaldehyde emitted by large core boards and adhesives used in decoration, and has nothing to do with latex paint. But the question in the reporter’s mind is: Can exterior wall paint be used to brush interior walls?
The reporter interviewed experts from the coatings industry, Mr. Zhu Chuan, editor-in-chief of China Paint magazine. He said that the interior walls of the interior walls are painted and brushless, and there is no problem from the perspective of environmental protection, and interior wall paints are not necessary for painting exterior walls.
â– The exterior wall paint focuses on the fast interior wall paint
According to reports, interior and exterior latex paints have their own special requirements. Exterior latex paint is used to paint on the facades of buildings. Therefore, one of the most important indicators is anti-ultraviolet radiation, and it will not change color if it reaches a long time irradiation. Interior wall paints are used for interior wall paints, and UV resistance is much lower than exterior paints.
The interior wall latex paint has high requirements on scrub resistance, and it is easier to contaminate the wall in home life and can be wiped with water at any time.
The exterior wall requires water resistance and requires self-cleaning. The film must be hard, smooth, and dirty.
The elasticity of interior and exterior wall paints is very important, and elasticity can prevent cracking caused by temperature and climate change.
External wall paint can be used for interior wall brushing because it also has water resistance, while interior wall paint does not have anti-sun function, so it can not be used to paint the exterior wall, but experts suggest that it is still special for special purposes.
â– Inner and outer wall paints have the same requirements for environmental protection
People have raised the question of whether exterior paint can be used to paint interior walls. The main concern is environmental issues. They are concerned about the low environmental protection indicators of exterior paint and cause indoor air pollution. In fact, as long as it is latex paint, no matter whether it is interior wall paint or exterior wall paint, there is no pollution.
The reporter and the Ms. Xue used the exterior wall Haobang brand latex paint distribution personnel to get to know that this kind of latex paint is made from the United States imported latex paint puree, both interior and exterior wall paint. Ms. Xue’s home uses the latex paint exterior paint. According to reports, the international requirement for the volatile weight of organic matter in latex paint (English abbreviation VOC) is no more than 250 grams per liter. Haobang brand interior and exterior wall latex paint test results are 160 grams per liter, lower than international standards, so the question of whether the exterior wall paint brushing the inner wall is not worried.
According to another report, the national anti-aging time test for exterior latex paints is 250 hours. The test results of the brand's anti-aging time reach 1,000 hours, and the performance of anti-ultraviolet radiation is very strong. The national standard for resistance to scrubbing of latex paints is: 100 qualified products, 300 first-class products, and over 3,000 times of Haobang brand latex paint.
â– Easy method to distinguish the quality of latex paint
No matter what kind of latex paint is used to brush the interior walls, the quality of the latex paint itself is critical. Consumers need to have some simple identification methods at the time of purchase.
Apply a latex paint to your fingernail or finger and, after a minute or two, a quality latex paint will form a film that is strong and glossy. If it is powdery, no filming is caused by too much additive. The main component of latex paint is a sticky cleaner, which is matched with an appropriate amount of pigment, additional material, and water (solvent). Adding additional materials can reduce the cost and the quality is difficult to guarantee. The counterfeit and inferior latex paint on the market is basically produced in this way. Consumers should pay attention to identification.
â– word solution
What is paint?
Often referred to as "paint." It is mainly made of resin or oil, with or without pigments and fillers, and it is prepared by dispersing media (organic solvents, water, etc.), coated on the surfaces of the objects to be protected and decorated, and can form a firm adhesion. Continuous film of viscous liquid or solid powder.
What is water-based paint?
As a kind of coating product, water-based paint is the main direction for the development of architectural coatings due to its safety, non-toxicity, resource conservation, and environmental protection, and will also be the ultimate destination for the change of paint varieties. There are four main types: water-soluble paints, hydrosol paints, water emulsion paints and powder water paints.
