Rockcote Otsumigaki Japanese Clay/Lime Finishes

A beautiful alternative to painted walls, Otsumigaki ("Otsu" for short), delivers a smooth, evocative aesthetic with a subtle lustre.

Formulated in the tradition of lime and clay based Japanese plasters, Otsumigaki is inherently sensuous: its presence in a room enlivens the senses and brings us back in touch with the natural world.

Meaning “polished and compressed “in Japanese, the product is applied with a trowel in two tight coats and then polished with a Japanese Trowel and Carnauba Wax. The polishing process compresses the lime and clay creating a soft, smooth, even feel across the surface and a pearly lustre finish.

ROCKCOTE Otsumigaki can be used in interior high traffic areas in residential settings such as entrances, stairwells and halls.

In contrast with the often dramatic and highly polished appearance of European inspired plasters (such as Venetian Plaster), Otsumigaki offers a dreamier, slightly stony look with a more subtle colour range in its patina.

Otsumigaki has a subtle elegance that gives walls life yet allows the surrounding elements in the space to speak for themselves. Create a dreamy feature wall in its natural colour and lightly polished to give warmth, depth and lustre.It can also be left natural for a smooth, natural aesthetic.

ROCKCOTE Otsumigaki can be tinted to a wide variety of colours, however it is neither possible nor desirable to achieve an exact colour match due to the uniqueness and variations in a natural mineral product.

ROCKCOTE Otsumigaki can be used over traditional natural plasters such as ROCKCOTE Earthen Render Coarse, as well as all common building substrates when prepared with a coat of Resene Construction Systems Resin with grit. It is not suitable for exteriors or wet areas.
