After the Spring Festival, everything is back on track, and in the home improvement industry, there will be a new year of decoration. Year-round renovation of the owners is best to re-calculate whether the renovation of building materials is sufficient before, if you do not do a good enough assessment before the year, the year after the resumption of work will encounter the case of inadequate decoration materials, the need to supplement the renovation of building materials When you need to pay attention to the main points of each type of building materials.

First, the main points of buying tiles

1, ceramic porcelain to distinguish

Tiles are generally divided into two types of ceramics and ceramics, which are subdivided into various small types. Porcelain bricks are crisp and melodious when tapped, with low water absorption and fine structure. They are not prone to cracks in the spring when the temperature difference between day and night changes; the ceramic bricks have higher water absorption, more structural holes, and the sound of the tapping sounds dull. .

2, view the test certificate

In addition to tapping the tiles, consumers can also ask merchants to present textural materials such as test lectures and certifications for the tiles. The best time to issue a test lecture is within half a year. The final “judgment conclusion” of the test lecture must be qualified, and the inspection and repair unit that issued the test lecture should have power. Test lectures generally include chapters such as CMA (Measurement Accreditation), CAL (Certification Accreditation), and CNAL (National Laboratory Accreditation). CMA is a basic necessity. A lower-qualified maintenance unit does not have a CAL chapter, and is national and highly qualified. The provincial maintenance unit has the CNAL chapter. When viewing a certificate, the certificate must correspond to the product being sold.

Now the certification of the tiles has been used 3C (CCC) certification, 3C certification is the same national certification standards, the previous other related certification will be the same to the 3C certification, through the 3C certified tiles, the reliability is better than the average.

Second, the purchase of decorative wood points

1, observe the appearance of wood

When purchasing plywood, composite panels, solid wood panels and other wood, pay attention to the appearance of wood. There are many burrs on the inferior plate, the quality of the plate after drying is clean and smooth, and the sandwich is even and dense, the plate surface is flat, the brilliance is uniform, there is no bending deformation, no broken rot, no wood grain slope, no resin marks, white spots And honeycomb eyes, and the festival is small and small.

2, see wood moisture content

The purchase of wood depends on the moisture content of the wood. When the moisture content of the wood is higher than the equilibrium moisture content of the environment, the wood shrinks and contracts, and vice versa. The main cause of dry cracking and deformation of wood is the high or low moisture content. Finally, don't just buy cheap, low-priced materials are usually shoddy and seriously overweight materials, should go to the regular market to buy, it is best to buy a brand of material. After receiving the wood, it must be opened for the first time to check if there is a package lost or if there is moisture.
