POSITION： 
1, view the mosaic specifications
Note that the particles are of the same size and the size of each piece is the same; the edge of each small particle is neat; the single piece of mosaic is placed on the horizontal floor to check whether it is flat.
2, view the mosaic back and back paper toughness strength
The back of the monolithic glass mosaic should have a jagged or stepped groove so that the paving will be stronger. Check the toughness and strength of the backing paper, and the qualified backing paper will not tear during handling and normal construction.
3. Check the mosaic for cracks.
Under natural light, the height of the mosaic is about 40 cm to visually detect the presence or absence of cracks, defects, missing edges and corners.
4, view the mosaic color uniformity
Randomly extract a few mosaics to form a square, lie flat in a place with sufficient light, and visually measure whether the gloss is uniform at a distance of 1.5 meters from it. If the gloss is uneven, it will easily fade in the wet bathroom and destroy the appearance of the wall.
5, pay attention to the test water absorption rate
Low water absorption is the key to ensure the durability of the mosaic. Therefore, it is necessary to check the water absorption rate before the purchase. The water drops to the back of the mosaic, the quality of the water droplets overflowing is better, and the quality of the lower penetration is inferior.
