Natural interior plasters, stucco and lime finishes

Natural lime coverings for those who design interiors: natural, breathable, hand-worked materials.

Natural mortars

Breathable plasters, lime stucco and cocciopesto for interiors: finishes that give depth to the surface without solvents or paints. They are designed for architects and interior designers looking for natural materials with an artisan character.

From the bathroom to the living area, lime is worked into matte or glossier finishes, in warm shades and tonal variations that no paint can reproduce.

Interior finishes

Where they are used

Natural interior mortars are used on walls, ceilings, niches, stairs and built-in furniture such as basins, benches and worktops, including sculpted, continuous surfaces. From the bathroom to the bedroom, from the living area to commercial and hospitality spaces, the same finish can cover several elements and give continuity to the room.

Textured finishes and smooth surfaces

Lime does not have a single look. It can be smooth and soft, with gentle clouding, or more textured, with a grain you can see and feel. The choice depends on the project, the light in the room and the character you want to give the space, and is always assessed on a sample.

For designers

Architects and interior designers can count on Prima Materia to choose the material, shade and finish, and for technical support even remotely. We distribute Guglielmino & Labnext natural mortars and, with the Labnext laboratory, develop custom formulations for particular needs.
