Sometimes in trade practice, you might even hear about &#8216;fourth quality&#8217;. But what do these terms actually mean, and is knowing the &#8216;quality&#8217; enough to judge if a tile is good?  <\/p>\n\n<p class=\"wp-block-paragraph\">The answer is not entirely straightforward. The definitions of first, second, and third quality are usually used as a <strong>commercial classification<\/strong> for the condition and appearance of the tiles. They should not be confused with technical characteristics such as wear resistance, slip resistance, water absorption, or the product&#8217;s intended use.  <\/p>\n\n<p class=\"wp-block-paragraph\">Therefore, when choosing <a href=\"https:\/\/izidaceramica.com\/en\/products\/\" target=\"_blank\" rel=\"noreferrer noopener\">porcelain and ceramic tiles<\/a>, it is advisable to consider both the quality of the specific batch and the technical specifications of the product simultaneously.<\/p>\n\n<h2 class=\"wp-block-heading\">What does first quality porcelain tile mean?<\/h2>\n\n<p class=\"wp-block-paragraph\"><strong>First quality<\/strong> usually refers to production that meets the requirements set by the manufacturer for the respective series and has passed standard quality control.<\/p>\n\n<p class=\"wp-block-paragraph\">With these tiles, the dimensions, shape, surface, edges, and decorative finish are within the product&#8217;s permissible limits. This does not necessarily mean that every tile will be absolutely identical to the others. <\/p>\n\n<p class=\"wp-block-paragraph\">In many modern porcelain tile series, especially designs imitating natural stone, marble, or wood, <strong>differences between individual tiles are a desired decorative effect<\/strong>. Colour and graphic variations should not automatically be considered a defect. <\/p>\n\n<h2 class=\"wp-block-heading\">What constitutes second quality?<\/h2>\n\n<p class=\"wp-block-paragraph\">Second quality usually designates tiles that may have certain visual or dimensional deviations that prevent the production from being categorised as first quality.<\/p>\n\n<p class=\"wp-block-paragraph\">Depending on the manufacturer and the specific batch, this may include:<\/p>\n\n<ul class=\"wp-block-list\">\n<li>small deviations in size or geometry;<\/li>\n\n\n\n<li>a more pronounced difference in shade;<\/li>\n\n\n\n<li>slight surface imperfections;<\/li>\n\n\n\n<li>small defects in the glaze or decoration;<\/li>\n\n\n\n<li>minor defects along the edges;<\/li>\n\n\n\n<li>differences between individual tiles within the batch.<\/li>\n<\/ul>\n\n<p class=\"wp-block-paragraph\">This does not necessarily mean the tiles cannot be used. In some situations, second quality can be an economical solution, but it is important for the buyer to know in advance what type of deviations are possible and whether they are acceptable for the specific project. <\/p>\n\n<h2 class=\"wp-block-heading\">Are there also third and fourth qualities?<\/h2>\n\n<p class=\"wp-block-paragraph\">Labels such as <strong>third quality<\/strong>, and sometimes fourth quality, can also be found on the market. Here we must be particularly careful \u2013 there is no universal system where all manufacturers necessarily classify porcelain tiles on the same scale from first to fourth quality. <\/p>\n\n<p class=\"wp-block-paragraph\">Lower categories usually involve production with more visible deviations \u2013 for example, more serious differences in dimensions, surface defects, damaged edges, or other imperfections. However, the exact meaning of the label depends on the specific manufacturer or retailer. <\/p>\n\n<p class=\"wp-block-paragraph\">Therefore, when purchasing a product labelled as second or third quality, it is sensible to ask <strong>exactly what deviations are permissible in that specific batch<\/strong>.<\/p>\n\n<h2 class=\"wp-block-heading\">Quality is not the same as PEI<\/h2>\n\n<p class=\"wp-block-paragraph\">One of the most common mistakes is confusing the quality of porcelain tiles with their <strong>wear resistance<\/strong>.<\/p>\n\n<p class=\"wp-block-paragraph\">PEI, for example, is an indicator related to the surface resistance of certain ceramic tiles to wear. A higher value does not mean &#8216;higher quality&#8217; in the sense of first or second quality, but indicates suitability for a specific load. <\/p>\n\n<p class=\"wp-block-paragraph\">Similarly, <strong>slip resistance<\/strong> ratings, often denoted by values like R9, R10, or R11, describe the surface behaviour under certain conditions, rather than the manufacturing quality of the tile.<\/p>\n\n<h2 class=\"wp-block-heading\">Size, calibre, and shade<\/h2>\n\n<p class=\"wp-block-paragraph\">In porcelain tiles, the <strong>calibre and shade of the batch<\/strong> are also important. Even a high-quality product can have minimal permissible dimensional differences or a difference in tint between different production batches. <\/p>\n\n<p class=\"wp-block-paragraph\">That is why it is recommended that the required quantity of tiles for a room be purchased all at once and from the same batch, whenever possible.<\/p>\n\n<p class=\"wp-block-paragraph\">It is also good practice to open several boxes before tiling and arrange the tiles beforehand. This allows natural variations in graphics and colour to be distributed evenly. <\/p>\n\n<h2 class=\"wp-block-heading\">How to recognise good porcelain tiles?<\/h2>\n\n<p class=\"wp-block-paragraph\">Instead of only being interested in whether a product is &#8216;first quality&#8217;, a better approach is to look at all the information about it.<\/p>\n\n<p class=\"wp-block-paragraph\">Check the size and thickness, the intended use for wall or floor, the surface, wear resistance, slip resistance, and other technical specifications. Requirements can vary for a bathroom, kitchen, hallway, terrace, or a high-traffic area. <\/p>\n\n<p class=\"wp-block-paragraph\">Also, browse the latest <a href=\"https:\/\/izidaceramica.com\/en\/catalogue\/\" target=\"_blank\" rel=\"noreferrer noopener\">Izida Ceramica catalogues<\/a>, where you can compare different series, sizes, colours, and surfaces.<\/p>\n\n<h2 class=\"wp-block-heading\">Are cheap porcelain tiles necessarily lower quality?<\/h2>\n\n<p class=\"wp-block-paragraph\">No. Price alone does not determine quality. A reduced price may be due to a promotional campaign, stock levels of a certain series, a change in collection, or other commercial reasons.  <\/p>\n\n<p class=\"wp-block-paragraph\">Therefore, a product at a good price should not automatically be perceived as &#8216;second quality&#8217;. When choosing, it is more important to check the specific product and its characteristics. You can also view the current <a href=\"https:\/\/izidaceramica.com\/promo\/\" target=\"_blank\" rel=\"noreferrer noopener\">porcelain tile promotions<\/a> from Izida Ceramica.  <\/p>\n\n<h2 class=\"wp-block-heading\">Which quality of porcelain tile should we choose?<\/h2>\n\n<p class=\"wp-block-paragraph\">For a standard home renovation, the safest choice is usually a product offered as <strong>first quality<\/strong> with technical specifications suitable for the specific room.<\/p>\n\n<p class=\"wp-block-paragraph\">Second quality may be suitable for certain projects when the buyer is aware of the possible deviations and they do not pose a problem for the intended use.<\/p>\n\n<p class=\"wp-block-paragraph\">The most important thing is not to view the terms &#8216;first&#8217;, &#8216;second&#8217;, or &#8216;third quality&#8217; in isolation. <strong>The quality of porcelain tiles is a combination of production control, geometry, surface, technical indicators, and correct intended use.<\/strong><\/p>\n\n<p class=\"wp-block-paragraph\">Well-chosen porcelain tiles are not simply those with the highest number or the highest price, but those whose characteristics match the place where they will be used.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>When choosing porcelain tiles, you have likely come across terms like first quality, second quality, or third quality.
