Lacquer paint construction is a very important project in home renovation. The majority of latex paints for wall treatment are used. If you haven't come into contact with the decoration related matters before, you must not know the construction of latex paint, if you want to understand Some information about the construction process of latex paint may wish to take a closer look at this article.
| 一ã€Introduction of latex paint |
Latex paint is mainly based on clear water as a diluent, but also as an organic solvent diluent, known as solvent-based paint (also known as oil-based cement paint), but not used in home interior wall decoration. Latex paint is also divided into primer and topcoat. The main role of the primer is to fill the pores of the wall to prevent the alkaline material from seeping out of the topcoat. The topcoat plays a major role in decoration and protection, distinguishing light from brightness, semi-gloss and peace (or matt), and the luminosity diminishes in turn.
What are the requirements for the performance of latex paint? The performance of latex paint for interior decoration mainly requires three aspects: hiding power, scrub resistance, and alkali resistance.
Covering power is the area where a certain amount of paint can cover the wall surface. It is usually expressed by the contrast ratio or the amount of paint required to cover a certain area. Scrubbing is the ability of a latex paint to withstand repeated scrubbing during use. Alkali resistance is an indicator of the stability of a latex paint. Because the wall material is mostly alkaline, it has a destructive effect on the paint film, and the durability of the latex paint determines the durability of the paint.
Latex paint requires good leveling in construction, no foaming, and moderate drying speed. Environmental protection requires low toxicity and low pollution.
How to choose latex paint When choosing latex paint, you can also check the manual first, and then get a preliminary impression on the outer package, trademark, and standard number. It is possible to ask the distributor for a product inspection report to see if the product meets the national standards.
Through the appearance judgement first to see if there is irritating odor, if it shows that VOC is too high. The paint of good quality is lacquer-free layering, no precipitation, no bubbles, no hard block. A light yellow liquid layer on the paint surface is normal.
What are the possible hazards to humans from latex paint? Many people have a misconception that latex paint is diluted with water, so it is an environmentally friendly product. In actual fact, latex paint may still cause harm to the human body. The main ones are:
Organic Volatile Compounds (VOC): There are as many as dozens of additives in latex paints. These additives are not properly selected. When latex paints dry, organic volatiles are released. If the concentration exceeds a certain concentration, it will cause harm to the human body.
Pigments: Some improperly-selected pigments contain lead, mercury, and other heavy metal elements that are harmful to human health.
