When decorating a house, you should buy tiles. There is also some knowledge about how to buy value-for-money and satisfactory tiles. Generally speaking, the principle of choosing ceramic tiles is: look, listen, three drops of water and four feet.

First, look at the appearance.

The color of ceramic tiles should be uniform, the surface smoothness and flatness should be better, the periphery should be regular and the pattern should be complete. Take out four or five pieces from a box to see if there are any defects such as color difference, deformation and lack of edges and corners.

Second, listen to the sound.

Tap with a hard object, the clearer the sound, the higher the porcelain degree and the better the quality. You can also hold a corner of the tile with your left thumb, forefinger and middle finger and hang it down easily. Tap the middle and lower part of the tile with the index finger of your right hand. If the sound is crisp and pleasant, it is the top grade; if the sound is dull and stagnant, it is the inferior grade.

Third, the dripping test.

You can drop water on the back of the tile to see seepage velocity after the water is dispersed. Generally speaking, the slower the water absorption, the greater the density of tiles; On the contrary, the faster the water absorption, the rarer the density and the better the internal quality.

Fourth, the ruler.

The higher the accuracy of the side length of ceramic tile, the better the effect after paving. Buying high-quality tiles is not only convenient for construction, but also saves working hours and accessories. Measure the size and periphery of each tile with a tape measure, and the one with high accuracy is the top grade.

In addition, observing its hardness, the ceramic tile is top grade, with good hardness, strong toughness and no breakage. Scrape each other with the edges and corners of tile fragments to see whether the broken fragments are fine or loose, brittle or soft, leaving scratches or loose powder. If the former is top grade, the latter is poor quality.

Whether the size is standard or not is the key to judge the quality of ceramic tiles. Use a tape measure or caliper to measure whether the diagonal and four sides of the tile are consistent in size and thickness. A good ceramic tile has a crisp sound, indicating a high porcelain content. If the sound is "click" and stubble breaks, it means that there is a crack in the brick.

Good tiles are easy to be installed by the master, and the installed effect is standardized.
