Look at the packaging
First of all, identify the factory name, address and trademark to avoid buying "three noes" products. Secondly, look at the product quality grade and water absorption.
Water absorption
The lower the water absorption, the higher the strength and the better the frost resistance. If users buy tiles mainly for paving or outdoor walls, they need to buy products with low water absorption, such as porcelain tiles or stoneware tiles. If the bricks purchased by users are mainly used for indoor walls, such as kitchen and bathroom walls, you can choose products with high water absorption, such as ceramic tiles.
Friction performance
If users buy tiles for paving, they need to check the friction coefficient and wear grade of the products.
