Please tell me what kind of paint to use to re-whiten the walls of an old house? Please answer in detail. Brush it yourself.

Old house renovation is recommended to use water-based interior wall paint painting, construction using one interior wall primer two interior wall topcoat construction method. Water-based coatings are coatings that use water as a solvent or dispersion medium. Water-based paint has the advantages of saving resources, no pollution, good protection and good corrosion resistance. Water-based coatings are mainly used in automotive coatings, metal coatings and interior and exterior wall coatings.

Expanded Information:

People in the renovation of the house, the toxicity of the building materials, especially the toxicity of the paint there is a misunderstanding of the main table:

First. It is unscientific to think that the toxicity of the paint will evaporate in a short period of time, and there is no harm as long as a few weeks pass. At room temperature, the volatilization of these toxic substances, dispersal is a long process, and long-term low-dose exposure to toxic substances will produce serious non-acute (due to non-acute, often unnoticeable) hazards, which has been confirmed by a large number of toxicological research results.

Secondly, it is unscientific to think that the amount of volatile organic compounds (VOC) in the paint can represent the size of the toxicity, VOC is only a source of the size of the toxicity of the paint, and not all VOC have high toxicity, and some volatile organic compounds do not have a great deal of toxicity, which is the basis for the development of a new generation of low-toxicity products. As a class of chemical indicators VOC does not equal toxicity.

Third, the toxicity of the paint can only be expressed through biological testing, physical and chemical testing is not a complete expression of toxicity.

Fourth, the toxicity of paint control refers to similar products in comparison with each other, is a process of dynamic development with technological progress. Therefore, it can not be compared with the non-toxicity of distilled water, good paint products, scientific expression should be low toxicity, not non-toxic.
