Trade terms for professionals and design studios
On a U.S. project the tile is only half the submittal; the other half is paper. For Otto, Mutina lists what it can put behind the product: a Health Product Declaration, an Environmental Product Declaration, a Declaration of Contents, an SVHC declaration, VOC emission data and its ISO 14001 environmental certificate, all available on request. The collection is also stated to contain more than 20% recycled material under LEED v4.1.
For designers who have to defend a finish to a sustainability consultant, that list matters as much as the color. And the color is the point of Otto: a palette of eight muted porcelain tile colors keyed to Emilia as Ghirri saw it through his lens, made with pigments ground in water, on one plank 6″ × 36″ and ⅜″ thick.
Mutina lists it for interior and exterior floors and walls alike, with a DCOF of 0.68. In an executive bathroom a single color can cover floor and ceiling-high walls with a matching base. La Mercanti requests the declarations from Mutina with the quotation, so they reach the architect in the same package as the samples.

The nominal size is 6″ × 36″; the actual caliber is 35.26″ × 5.81″, and the thickness is ⅜″. Use the actual size when you set out a layout to the joint, because the nominal figure is rounded.
Mutina makes them only with ceramic pigments and glazes ground in water, without digital printing. The process gives naturally pastel tones with a dusty, quiet finish rather than a printed image sitting on the tile.
Yes. Mutina rates it for exterior floors: it is frost resistant under ISO 10545-12, with a wet pendulum value of 40 and R10. The setting bed, drainage and slope still have to follow the project’s own exterior detail.
More than 20%, as stated by Mutina for LEED v4.1. It applies to the whole collection, so every shade counts toward the same credit in a submittal.
Both work: Mutina designed the plank for aligned and staggered layouts alike. Straight emphasizes the length of the room; a half-offset stagger breaks the relief into a denser rhythm and asks for a little more cutting at the ends.
Otto’s colors are soft and shift with the light. Five steps to pick the right one on site, not on screen.
From the eight Otto shades, keep three that fit the materials already chosen: millwork, fixtures, wall paint.
La Mercanti ships Otto samples of those three; the cost is fully credited against the order once it is confirmed.
Lay the Otto samples on the floor where they will go and check them in the morning and late afternoon. Pastels read warmer or cooler with the sun.
Hold a grout sample against each Otto shade. With a 1/16″ joint the grout barely shows, but a strong contrast still changes the field.
Write the chosen Otto shade with its code, for example Salvia S7, on the finish schedule so the order matches the approved sample exactly.
