1. Look

Look at the color, look at the effect of water. Tiles with no chromatic aberration, no size, flat, clear texture (smooth texture, higher intensity and better gradation), and clear color decomposition are better quality tiles. If dripping water on the back of the bricks spreads slowly, the front has little or no water seepage, the density is higher, and the quality of the bricks is better.

2. Than

The comparison is mainly to compare the size, thickness, gloss, weight, etc. of the bricks. Two bricks are randomly selected. The size, thickness, color, gloss, and weight of the brick and the brick must be consistent. The pattern patchwork must be unified, and the gap between the brick and the patchwork must not exceed 1mm. It is also necessary to compare the actual data of the bricks with the value indicated on the product. If the value is inferior, the quality of the brick is also poor.

3. Knock

Tap to hear the sound, tap to see the section. If the sound is crisp and pleasant, the tiles have high density and good strength, while the sound is dull, and the water absorption rate is high.

4. Test

The measurement is mainly to measure the glaze, slip resistance, etc. When testing, scratch the glaze of the tile with a sharp object to see if there are scratches. If there is, it means that the glaze of this type of tile is poor. Lay a few floor tiles flat on the ground, sprinkle some water, step on them and feel it for yourself. If it is really a non-slip product, then there will be astringent feeling under the feet.
