When purchasing tiles, there are several key factors to consider in order to ensure you select high-quality products that meet your needs. First, pay attention to the water absorption rate of the tile. The lower the water absorption, the more stable the tile is, making it ideal for areas with high humidity or moisture, such as bathrooms and kitchens. A good tile will not develop black spots or other issues due to moisture. To test this, place a drop of water on the back of the tile. If the water spreads slowly and the tile feels dense, it’s likely a top-grade product.
Next, check the density and hardness of the tile. Tap the tile lightly with your hand. A crisp, clear sound indicates a high-density, hard tile, which is a sign of quality. If it makes a “squeaky†noise, it may be weak and poorly sintered. A slight “click†suggests better quality and durability.
Look at the color and surface finish. Use a hard object to gently scratch the glazed surface. If it leaves marks, the quality may be poor. Also, check for pinholes—these can trap dirt and affect the appearance over time. The color should be even and consistent, without visible flaws.
Assess the flatness of the tile by placing four tiles on a flat surface and checking if they sit evenly. If they are uneven or don’t align properly, it could lead to an unattractive installation. Additionally, tap the surface of the tile with your palm. A low, dull sound usually means a good tile, while a bright, echoing sound may indicate poor quality. Don’t overlook the importance of comparing tiles directly, as this is often the most reliable method.
Examine the glaze carefully. High-gloss tiles should appear clear and shiny, while matte or semi-matt finishes should look soft and evenly reflective. Scratching the surface with a hard object can reveal whether the glaze is sufficient. If scratches appear, the tile may not be well-glazed, and cleaning could become difficult after polishing.
Check the size and specifications of the tiles. Use a caliper to measure the diagonal lines and ensure the dimensions are standard. Irregular tiles can create an uneven layout when installed, leading to an unprofessional appearance. Also, inspect the tile for any signs of warping or deformation. A straight, flat edge indicates better quality and easier installation.
Evaluate the pattern and design. The colors should be vivid and realistic, with no obvious defects like missing color, broken lines, or misalignment. This ensures the final look is visually appealing and professional.
Pay attention to the packaging. Look for clear labels including the factory name, address, and trademark to avoid purchasing “three-no†products (no name, no address, no trademark). Check the water absorption level, as lower absorption generally means higher strength and better frost resistance. For floor or outdoor use, porcelain or enamel tiles are recommended. For interior walls, ceramic tiles with higher absorption rates may be suitable, but they require stronger resistance to cracking, thermal shock, and chemical damage.
Consider the friction properties if the tiles are for flooring. Check the friction coefficient and wear level to ensure they are safe and durable for foot traffic.
Finally, assess the overall surface quality. Stand about one meter away from the tile and observe under good lighting for any defects like chipped glaze, cracks, or dirt. At three meters away, check for color variation to get a sense of the gloss and consistency. Tap the tile with your hand or a hammer—if it produces a metallic echo, it suggests a solid structure. A dull or muffled sound may indicate internal structural issues.
By taking these steps, you can make a more informed decision and choose tiles that are both functional and aesthetically pleasing.
