<p><strong>1. How are black spots formed on the surface of polished tiles?</strong></p><p><br></p><p>The black spots on the surface of the <a href="https://www.overlandceramics.com/procelain-tile" rel="noopener noreferrer" target="_blank"><strong>polished tiles</strong></a> are mainly due to the raw materials containing iron. There are many reasons for the formation. For example, the raw material impurities are not cleaned up, and the impurities in the furnace during the firing will cause black spots to appear.</p><p><br></p><p><strong>2. Cracks appear on the polished tiles after a period of time</strong></p><p><br></p><p>Polished tiles are fired at high temperature, and the green body must be porcelainized to be considered a qualified product. Normal use will generally not cause cracks. If the strength of the cement is too high, the hardening of the cement will cause cracks in the polished tile with a sharp change in volume; if the tile does not leave a seam during the paving, the tile will expand due to thermal expansion and contraction, and cracks will also appear.</p><p><br></p><p><strong>3. Can polished tiles be used in toilets and kitchens?</strong></p><p><br></p><p>The bathroom and kitchen are damp areas, generally not suitable for laying polished tiles, and matte <a href="https://www.overlandceramics.com/glazed-tile" rel="noopener noreferrer" target="_blank"><strong>glazed tiles</strong></a> can be used. In addition to these two areas, polished tiles can be applied to other areas.</p><p><br></p><p><strong>4. The reason for the color difference of polished tiles after paving</strong></p><p><br></p><p>1）The products have been mixed at the factory, and the polished tiles of different color numbers are mixed;</p><p><br></p><p>2） The construction workers did not arrange and paste according to the color number on the packing box;</p><p><br></p><p>3）The light conditions at each location are different after paving, which causes visual chromatic aberration.</p><p><br></p><p><br></p><p><strong>5. Will it be easy to arch in winter with polished tiles?</strong></p><p><br></p><p>If the indoor temperature is lower than 5°C, there is ice residue in the mud, and the tile is not suitable for room temperature construction, etc. In addition to these conditions, it is not suitable to lay tiles. There is no direct relationship between the arching of tiles and the laying of tiles in winter. The reason for the arching of the tiles is caused by the absence of gaps in the tiles, the gaps being too narrow or the hollowing of the tiles.</p><p><br></p><p><strong>6, deal with the problem that the polished tile is easy to break</strong></p><p><br></p><p>The hardness of polished tiles is high. When the cutting machine is used, the temperature of the cutting position of the tiles and the proficiency of the workers will cause the tiles to crack. Therefore, a professional worker is required to cut the <a href="https://www.overlandceramics.com/product" rel="noopener noreferrer" target="_blank"><strong>ceramic tiles</strong></a>, and water is sprayed at the cutting position to reduce the temperature while cutting, so as to ensure the quality of the cutting.</p><p><br></p><p><strong>7. Repairing the polished tiles</strong></p><p><br></p><p>If the polished tiles falling off are not damaged, the mud on the back of the tiles can be scraped off, and the back of the tiles can be evenly coated with tile adhesive or mud, and then pressed tightly to stick the polished tiles.</p><p><br></p><p><strong>8. Daily maintenance of polished tiles</strong></p><p><br></p><p>1） Mold spots, black spots, tea stains, etc. can be removed using bleach, as long as the bleach is soaked in the stain for a few minutes and then wiped clean. If it is a stain that has penetrated into the tile for a long time, the soaking needs to be extended for several hours.</p><p><br></p><p>2）Paint, oil stains, etc. should be removed with alkaline cleaners; cement, scale, rust spots, etc., must be wiped with hydrochloric acid several times until clean.</p><p><br></p><p>3）If the polished tiles have been used for too long and the surface scratches and stains are already very serious, you need to ask a professional cleaning company to re-wax and refurbish.</p>
