1. Look at the appearance of the tiles. To see if the color of the entire tile is uniform, whether the surface finish and flatness are good, and the surrounding rules and patterns are complete, we can take out four or five tiles from a box to observe and see if there is no color difference, distortion or lack of edges. Angle and other defects.
2. Listen to the sound. Tap gently with a hard object. If the sound is more crisp, the higher the density of the tile, the better the quality. You can also pinch the corner of the tile with your fingers and sag easily, then tap the middle of the tile with the index finger of your right hand. If the sound is clear and pleasant, the quality is good. If there is a "click" sound in the clear knocking sound, there is a crack in the brick. Therefore, a good tile is easy for the master to install and the effect is very beautiful.
3. Drip test. You can apply some water and drip it on the back of the tile to see how fast the water will spread after the water is dispersed. Normally, the slower the water absorption, the higher the density of the tile. On the contrary, if the water absorption is fast, the tile The density is sparse, so the higher the density, the better the quality of the tile.
4. Ruler. Whether the size is standard is also the key to judging the quality of the tile. Use a tape measure or a ruler to measure the size of the four sides and whether the diagonal and thickness of the tiles are uniform. The better, buying a good brand of tiles will not only facilitate construction, but also save construction time and use auxiliary materials.
