Wood lacquer selection skills

In the decoration of a household, the environmental protection of the wood paint in the decoration paint determines the environmental protection index of 90% of the decoration paint. Therefore, the choice of the decoration wood paint is very important, and must not be underestimated. At present, there are three types of wood lacquers on the market: NC (nitrocellulose lacquer), PU (polyester lacquer) and W (waterborne wood lacquer). These three products have their own advantages, so we have to choose when purchasing. Ideal for your home renovation needs.

The advantages, disadvantages and suitable groups of these three types of products:

·NC lacquer

·W waterborne wood lacquer

After a clear understanding of the various wood lacquers used in home decoration, I basically know what kind of wood lacquer is needed in my home, but in the face of the marketing of many brands in the market or some construction units such as decoration companies and oil carpentry groups. When recommending, consumers often don't know how to choose a brand. Here are some practical tips.

A. Look for the brand or the regular and powerful distributors. Paint and coating products are not only related to the aesthetics and comfort of the living environment, but more importantly, they are related to the health of the family and cannot be sloppy. The products operated by regular dealers are regular brands that have passed the quality and meet the environmental protection standards, and have many years of experience in product use. For its own long-term development, it will never do anything to harm consumers.

B. Focus on product matching. Primers, topcoats, etc., can't buy or buy less because of the high price of such things, but should consider the amount of demand put forward by the oil carpentry master and the advice of the shopping guide, and then purchase.

C. Conduct anti-counterfeiting queries for products. Nowadays, most big brands have anti-counterfeiting inquiry systems, so consumers should not feel that they have spent a few cents on the inquiry fee or wasted ten minutes, so they will not inquire about the products.

D, seriously understand the brand's after-sales service. After confirming the brand's after-sales service content, determine whether to purchase.

E. When the master is working, pay attention to smell. If the smell has no odor or a particularly weird taste, if it smells aromatic, it is recommended that you pay special attention to the highly toxic substances; if it is PU, NC paint is recommended to just feel it, if it is water-based wood paint you can Free to stay in the room during construction, because the waterborne wood paint will not cause any physical harm to the constructor.
