Product Specifications:
The document lists various porcelain tiles under different categories such as Rauk-R Sand, Rauk-R Nube, Tors-R Beige, Tors-R Gris, Tepuy-R Basalto, Tepuy-R Mix, and Lenar-R series. Each category includes tiles of different sizes, such as 29.3x29.3 cm, 59.3x59.3 cm, 44.3x89.3 cm, and 80x80 cm. The tiles are described as having low water absorption, high mechanical performance, and resistance to chemicals and frost, making them suitable for both interior and exterior use in residential and commercial buildings.

Fixing Procedures:
The document provides detailed instructions for fixing porcelain tiles. It emphasizes the importance of ensuring the correct size, shade, and quality of tiles before installation. It recommends mixing pieces from several boxes for uniformity and using C1 or C2 adhesives for high adherence and water resistance. The document advises against the Dot and Dab Method and recommends the Thin Layer Method for tile installation. It also highlights the importance of not walking on tiles during the adhesive drying time and maintaining a minimum joint width between tiles.

Maintenance Recommendations:
After installation, tiles should be protected from damage during construction work. Cleaning should be done with commercial detergents or acid-based cleaners, considering the chemical resistance of the tiles. Acid cleaning should not be performed on newly laid tiles. Routine cleaning requires only water and possibly an alkaline cleaner. The use of waxes or oils is discouraged.

Technical Standards and Characteristics:
The document outlines the technical standards for the tiles, including water absorption, flexion resistance, surface abrasion resistance, slip resistance, thermal expansion, and chemical resistance. It specifies that the tiles conform to UNE-EN 14411 standards and provides detailed technical data for each characteristic.

Important Notes:
The document notes that technical specifications are valid only for first-choice products. It disclaims responsibility for tiles not fixed or maintained according to the manufacturer's recommendations. Special care is advised for hand-painted tiles during fixing and cleaning.
