WHAT ARE THE CONSIDERATIONS FOR TILE SELECTION?
• In choosing the right product, visual and aesthetic appearance and technical features of products are important.
• Never apply wall tiles to the floor and outdoors.
• Slabs and porcelain tiles can be applied to the wall using appropriate adhesives.
• Porcelain tiles with low water absorption value can easily be laid outdoors.
• Slabs should only be used together with suitable adhesive and waterproof, frost-resistant joint sealant.
• Tiles to be laid in areas with heavy foot traffic should be selected from products with high abrasion class PEI).
• In wet areas such as near the pool, high non-slip tiles should be used.
WHAT ARE THE TYPES OF CERAMICS?
• Ceramics can be divided into three product groups according to their structure and specifications:
Slabs - Wall Tiles - Porcelain Tiles (Glazed and Unglazed)
DEFINING COLOR, TONE AND TEXTURE DIVERSITY (V classification)
• V1 = SAME APPEARANCE (UNIFORM): Slight and insignificant differences between tiles, each tile has the same texture, color, tone and motif.
• V2 = SLIGHT DIFFERENCE: There may be differences between the same colors in texture and/or pattern. The overall appearance of the tiles is quite similar.
• V3 = MODERATE DIFFERENCE: Although a color in a tile may give information about colors in other tiles, colors in a tile may differ significantly in terms of color intensity. A color that appears to be negligible on the tile can be a predominant color on another tile.
• V4 = RANDOM DIFFERENCE/DIVERSITY: In terms of color, a tile can be completely different from another tile. These tiles cannot be selected by the consumer to create a few patterns. Due to color differences, there is a natural appearance in the tiles. So, each installation has a unique structure.
WHAT ARE ABRASION CLASSES? WHAT DOES PEI STAND FOR?
• Glazed slabs are evaluated in 5 grades based on their abrasion values. The classification of surface abrasion resistance is made according to the test described in TS EN 10545-17 and is defined with a value between PEI 1 and 5.
• Generally, dark colored products have a lower PEI grade than light-colored products.
• When choosing a product, products with appropriate abrasion resistance (PEI grade) should be preferred, taking into account the foot traffic in such area.
PEI .I : Suitable for floors where there are no abrasive materials and on which people will walk with naked feet or soft footwear (such as bathrooms, bedrooms)
PEI .II: Suitable for floors with small quantities of abrasive materials from time to time, on which people will walk with sports shoes and rubber footwear (dining room, living areas)
PEI .III: Suitable for floors with small quantities of abrasive materials, on which people will walk with leather-sole shoes (corridors, hall entrances, terraces)
PEI. IV: Suitable for floors with abrasive materials and high foot traffic (such as pharmacy, bank, school, hotel lobbies)
PEI .V: Suitable for floors with high quantities of abrasive materials and extremely high foot traffic (such as bazaars, cafeteria entrances and circulation areas, restaurants)
PEI. V class products should also have high staining resistance.
WHAT DOES LAPPATO MEAN?
• Polishing of glazed or unglazed porcelain tiles (after firing) by light mechanical abrasion. They are coated with a special film layer - mostly for staining -resistance.
• Surfaces get brighter and gain a more stylish look.
• Semi-polishing (lappato) process is applied to tailored wall tiles and granular slabs, and semi-gloss tiles are also produced. Therefore, a different effect is obtained on the surface of the tile.
WHAT IS RECTIFIED TILE?
• It is a sizing process to remove the size differences between the tiles.
• After this process, the tilted part at the tile edges are also eliminated; so, an integrated image is achieved at the installation.
• It is recommended that the tiles are laid with at least 1 mm joint.
WHAT IS NON-SLIP? WHAT IS A NON-SLIP PRODUCT?
• Slabs / Porcelain tiles have a slippery quality that varies according to their surface properties.
• Tiles with non-slip properties are defined as "anti-slip".
• DIN 51130 and DIN 51097 (German standards) and ASTM C1028 (wet/dry COF) and ANSI B101.3 (wet DCOF) (US standards) are commonly used in non-slip classification.
• Sliding angles or friction coefficients are measured according to the relevant standards and this gives information about suitable locations for their application.
• Anti-slip products are preferred in areas with high risk of slipping, such as pools and near pools, and in industrial areas with slippery floors due to oil etc.
