SYSTEM & SURFACE
They are laid according to the traditional system or with adhesive. Advised width of joints minimum 3 mm. The product’s slight irregularity in width and surface finish betrays the artisan method of working by hand. Preferred use in interiors, particularly for important restorations. To be treated after laying.
USE
-Due to its surface finish, “Levigato” is preferably used for interiors or places without direct contact to exteriors. -For inside use the material requires a protective treatment in order to preserve the material’s original aesthetic and physical characteristics and to maintain the tiles unaltered over the years.
FLASH VERSION
The Brushed Cotto Sannini treated with Flashsystem l’an exclusive method of treatment carried out in the factory by Sannini. It entails a complete cycle of working, using avantgarde techniques and products studied to preserve the terracotta’s natural qualities as a sign of respect to the environment and its ecosystem.
All materials used for the treatment of Flash are non-toxic, and being water-based, do not contain solvents. Essential feature of Flashsystem is its in-depth protection which guarantees resistance to stains, damp rings and efflorescences, although the original transpiring nature of the material is maintained.
As a consequence, the cladding with these ready-to-use products presents itself with the colour and aspect of terracotta treated traditionally on site with acids and waxing. Such operations become superfluous since Flash products do not alter when laid if the mounting instructions are followed correctly.
