Vitreo can be installed on horizontal or vertical surfaces, interior or exterior; It is suitable for wet areas, such as showers, swimming pools and building facades. The size of the tesserae (2 x 2 cm | 3/4″ x 3/4″) and the frequency of the joint (~ 1 mm | 2/48”) means that the surface has inherent slip resistance. Although the mosaic is waterproof, this does not preclude waterproofing the foundation for swimming pools and similar applications.
