More Worry-free Purchase Guide

Must-see core parameters: Don't be fooled by the salesperson. These 5 parameters determine the quality of ceramic tiles
When choosing tiles, focus on the parameters before considering the design. Only if the parameters meet the standards can we talk about durability. The key points to pay attention to are water absorption rate, wear resistance, anti-slip rating, stain resistance, and thickness. Remember the "domestic qualification standards". No matter how much the salesperson says, let the parameters speak for themselves:
1. Water absorption rate: the "lifeline" of household tiles, the lower the better
Qualification criteria: floor tiles ≤0.5%, wall tiles (full-ceramic) ≤0.5%, ceramic tiles ≥10% (excluding use in kitchens and bathrooms);
How to judge: If the packaging is labeled "GB/T 4100-2015 Ceramic Tile (Bla)", it indicates that the content of all-ceramic is ≤0.5%. If it is labeled "Ceramic Tile (Blb/Blc)", avoid it.
2. Wear resistance: Judged by "Mohs hardness + number of revolutions", a level of ≥4 is sufficient for household use
Mohs hardness: **≥4 grade** for household use, capable of resisting daily furniture friction and shoe sole trampling, with grades 5-6 suitable for high-frequency trampling areas (entryway, living room);
Wear resistance rating: For household floor tiles, **≥6000 cycles**, and for commercial use, ≥10000 cycles. Products marked with "Wear resistance grade Ⅲ or above" on the packaging are considered qualified.
3. Anti-slip grade: It is of utmost importance, especially for elderly people, children's rooms, kitchens, and bathrooms
National standard grade: Judged by the "R value", household floor tiles should be at least Grade R10, and wet areas such as kitchens, bathrooms, and balconies must be at least Grade R11. For households with elderly or children, Grade R12 is preferred;
Avoid pitfalls: Matte tiles do not necessarily mean anti-slip tiles, and glossy tiles also come in high anti-slip versions. Don't rely on visual judgment. Ask the salesperson for an anti-slip test report, or conduct a "water pouring test" on site (if there is no slippery feeling when stepping on it, it is qualified).
4. Stain resistance: Determined by the glazing/surface craftsmanship, the denser it is, the better its stain resistance
Test method: Draw a line on the tile surface with a marker pen on site, let it stand for 1 minute, and then wipe it with a dry cloth. If there are no residual marks, the stain resistance is considered to be qualified;
Key point: The surface of fully-glazed marble tiles and polished tiles is coated with a nano-anti-fouling layer, providing superior stain resistance compared to ordinary polished tiles. For kitchen and bathroom tiles, styles with an anti-fouling layer are preferred.
5. Thickness: Thicker is not necessarily better; it's the suitable application scenario that matters
Floor tiles: For regular tiles, the thickness is 8-10mm. For large-sized tiles (750×1500mm and above), the thickness is selected to be 10-12mm, taking into account both flatness and impact resistance;
Wall tiles: For kitchen and bathroom all-ceramic tiles, choose 6-8mm thickness, which is thin and lightweight and less prone to hollowing. For background wall decorative tiles, you can choose 12-20mm thickness according to the design.
Additional reminder: Qualified tile packaging must bear "3C certification, implementation standards, water absorption rate, specifications, and manufacturer". It is absolutely not advisable to purchase "three-no tiles" without any identification, as they are prone to quality issues in the future.
