When it comes to home decoration, many households opt for a semi-package approach, where they purchase materials like ceramic tiles, sanitary ware, and paint themselves. However, due to the information gap in the market, consumers often fall into traps when buying these items. Gaining some basic knowledge about purchasing can save time and effort, while helping you secure genuine and high-quality products that meet your expectations.
Let’s take ceramic tiles as an example. Simply choosing a brand or color isn’t enough. To avoid being scammed, here are some essential tips:
1. **Check the Store’s Legitimacy**
Not all branded stores sell authentic products. Some may carry fake items or even resell old stock without proper authorization. Before making a purchase, always verify with the manufacturer to ensure the store is authorized.
2. **Inspect the Packaging and Labels**
A genuine product should have clear and detailed information on the packaging: factory name, address, product name, after-sales contact, specifications, quantity, trademark, production date, and applicable standards. Avoid “three-no†products (no name, no address, no quality). For porcelain tiles, look for the CCC certification mark, and choose those that meet category A radionuclide requirements. For instance, Tianwei Ceramic’s packaging includes ISO9001, ISO14001, and China Environmental Label certifications, ensuring quality and safety.
3. **Examine the Tile’s Appearance**
High-quality tiles should be smooth, with a clear glaze and consistent color. Under good lighting, check for surface defects such as cracks, bubbles, spots, or unevenness. The size should be standard—use a caliper to measure the diagonal. A well-designed tile will have a realistic pattern, sharp edges, and a clean back with minimal imperfections. Take the "Glazed Cool Angel" tile as an example—it has a crystal-clear surface, warm texture, and vibrant colors.
4. **Test the Density and Hardness**
Tap the tile lightly. A crisp sound indicates high density and hardness, while a dull sound suggests poor sintering. You can also scratch the glaze with a hard object; if it leaves marks, the quality is likely low. Check for pinholes, which can trap dirt and affect aesthetics.
5. **Check Water Absorption and Friction Coefficient**
Lower water absorption means better stability, especially for areas like bathrooms or kitchens. Place a drop of water on the back of the tile; if it spreads slowly, the tile is of good quality. For floor tiles, ensure a high friction coefficient to prevent slipping and wear.
6. **Assess the Flatness**
Tiles should have straight edges for easy installation and a neat finish. Place four or more tiles on a flat surface and check if they lie evenly. According to national standards, porcelain tiles should have a deformation of no more than 0.2%, while glazed tiles should not exceed 0.5%.
By following these steps, you can make informed decisions and avoid common pitfalls when purchasing building materials. Taking a little extra time to research and inspect can lead to long-term satisfaction and a beautifully decorated home.
