Generally speaking, the kitchen and bathroom first decide on the wall tiles, and then match the floor tiles. The wall tiles are light-toned matte tiles, about 300mm × 450mm for larger areas, about 250mm × 330mm for smaller areas, and decorative pattern tiles. Generally, only 2-3 pieces are used for a room. Any more will affect the effect. Use anti-slip tiles for kitchen and bathroom floor tiles. Living rooms and bedrooms generally use 600mm×600mm and 800mm×800mm floor tiles. 2. Choose regular brands. Matt tiles have rich colors and textures, and the paving effect is warm and elegant. They are stain-resistant and slip-resistant. Polished tiles have a high finish. In addition to infiltrated polished tiles, there are also micro-powder polished tiles. The surface particles of micro-powder polished tiles are more delicate and have higher smoothness and stain resistance. High-quality polished tiles have no jagged edges, no chipping, pure colors, clear patterns and textures, and strong three-dimensionality. When consumers choose ceramic tiles, they can scratch the surface with iron nails or keys if possible, leaving no traces for high hardness; they can also pour ink and tea on the surface and wipe it off after 10 minutes, leaving no traces for durable tiles. Strongly polluting. Choose a regular brand. In addition to ensuring quality, regular brand tiles also have perfect after-sales service. If the tiles have color differences, they can be replaced for free. Bode Tiles sales staff believe that when choosing vitrified tiles, you should choose ones that are smooth, bright, delicate and comfortable to the touch. Similarly, the "test ink" method can also be used to identify the anti-seepage performance of vitrified bricks. The fastest-selling vitrified tiles now are 800 mm×800 mm. Fewer and fewer people are buying 600 mm×600 mm, while more and more people are buying 1000 mm×1000 mm. When selecting ceramic tiles, the ones with crisp knocking sounds are of good quality; those with low water absorption rates generally have higher density, and those with the same specifications and weight have greater density; overlapping two bricks can check the flatness of the ceramic tiles; measure the color difference of the ceramic tiles. In addition, pay attention to whether the ceramic tile grade and color difference between the sample and the warehouse are consistent. Also, you should buy a few more pieces than the actual budget to avoid color differences between different batches, or if you don’t have enough, buy it immediately and delay the construction period. 3. Check the test report When consumers choose ceramic tiles, they can identify the quality of the ceramic tiles by checking the test reports and certification certificates provided by the merchants. The best time for the test report to be issued is within half a year. The final "judgment conclusion" of the test report must be qualified, and the inspection unit that issued the test report must be authoritative. Test reports generally have CMA (Measurement Certification), CAL (Censorship Approval), CNAL (National Laboratory Accreditation) and other chapters. The number of chapters reflects the qualifications of the inspection unit. CMA is the most basic must have, and some have lower qualifications. Inspection units do not have CAL seals, while national-level and provincial-level inspection units with higher qualifications have CNAL seals. When checking the certification certificate, the certificate must correspond to the product being sold. This year, 3C certification for ceramic tiles has begun. 3C certification is a unified national certification standard. Other previous related certifications will be unified into 3C certification. Ceramic tiles that have passed 3C certification are reliable. The sex is better than average. The main testing items for ceramic tiles are radioactivity. Whether radioactive substances exceed the standard is the primary issue that consumers pay attention to when purchasing ceramic tiles. The radioactivity testing of ceramic tiles is based on the "National Mandatory Standard for Radionuclide Limits of Building Materials GB6566-2001", which mainly detects the radioactivity of radium, thorium and potassium. At present, the radioactivity testing of regular brand ceramic tiles rarely exceeds the standard. (3) Pay attention to the following matters when laying ceramic tiles: 1. Before tile laying, random inspections are required to see if the grade and color difference are consistent with the samples seen. If confirmed, it is best to have the person in charge of the construction sign for it, otherwise notify immediately Tile sellers. 2. If the wall is made of putty or calendered cement, it must be removed and roughened first. Wall tiles must not have less than 1/3 of a brick. 3. The ground should be fully wetted, and horizontal lines should be drawn on the wall and pre-arranged on the ground to ensure that the low bricks in each room are on the same level. 4. It is best to use the "dry laying" method for floor tiles. 5. The bathroom floor tiles should have a slope of about 1, and should be about 10mm lower than the outside floor tiles. The slope of kitchen floor tiles should be appropriately reduced. 6. When meeting the sun angle, a 45-degree cut angle should be used, and the lower edge of the waistline should be the upper edge of the window. 7. Drilling will be carried out 3-5 days after the wall tiles are laid, and construction will be carried out the next day after the floor tiles are "dry laid".
