Natural Materials

Natural Materials

The Natural Materials by ROCKCOTE range draws inspiration from nature to provide beautiful natural interior and exterior finishes that don’t compromise your health or the environment.

From the glass-like polish of ROCKCOTE Venetian Plaster through to the on-trend textured look of ROCKCOTE Earthen Render, our Natural Materials are versatile and help bring a distinctive personality to each project.

Drawing on the traditions of the original master artisans of Europe and the Orient who applied natural wall plasters by hand, ROCKCOTE's natural decorative finishes are applied by passionate modern artisans. The finishes are suitable for a range of project types including homes, offices, bars, hotels and restaurants.

These breathable plasters and paints can be used on a wide variety of wall surfaces, including modern plasterboard and concrete as well as traditional or eco-build materials like straw bale and hempcrete, with stunning results. Most products are based on natural lime or clay or a combination of both and specially formulated for exceptional performance on modern buildings. 

All products in the range are completely natural, free of dangerous chemicals and Volatile Organic Compounds (VOCs) and produce no residual odour or offgassing. They have low embodied energy (energy necessary for the entire product lifecycle) and are fully recyclable which means they can be returned to the earth after use.

Colouring Natural Materials by ROCKCOTE

Most products in the Natural Materials range can be tinted to a wide range of colours using natural oxides. View the Natural Materials by ROCKCOTE Colour Range

The benefits of lime plasters

Lime is an amazing building material: more environmentally friendly and economical than cement, and also carbon neutral. Like cement, lime gives off carbon dioxide during manufacture. Yet, unlike cement, lime actually re-absorbs carbon dioxide when it sets making lime an ideal choice for conscious living. Lime is burnt at a lower temperature than cement in the production process (900°C as opposed to 1300°C) and therefore produces 20% less carbon dioxide. Lime is essential in the building of any natural house, including straw bales, timber and earth.

ROCKCOTE Venetian Plaster, ROCKCOTE Velvetino and ROCKCOTE Lime Plaster Bascote are all lime based plasters with ROCKCOTE Otsumigaki a combination of lime and clay.

Benefits of Lime: 

  • Biodegradable

  • Recyclable

  • Allows the building to "breathe". Water can escape by evaporation, unlike cement where water can only escape by being absorbed into the bricks, risking damp and substrate erosion.

The benefits of clay plasters

Clay based plasters can create stunning effects ranging from a rustic earth natural clay to a smooth, polished finish. 

  • They are porous, allowing the building structure to breathe

  • They have a thirst for moisture that helps to regulate relative humidity in the atmosphere, improving air quality and resisting mould growth.

  • Create a healthier indoor atmosphere by releasing healthy negative ions into the air (See RHS box)

ROCKCOTE Earthen Render Medium, ROCKCOTE Earthen Render Coarse and ROCKCOTE Clay Plaster Decor are all clay based plasters with ROCKCOTE Otsumigaki a combination of clay and lime.

Choosing the right product for your project

Choosing the right natural material for your project needs to take into account more than just aesthetics  The following also need to be considered and should be addressed by the applicator with the client for each natural materials project:

  • Location 
  • Environment
  • Substrate
  • Construction type (residential, commercial, high rise)
  • Green Rating (ie. use of environmentally friendly materials)
  • Skills and expectations of the applicator or artisan
  • Expectations of the client

The application of ROCKCOTE Natural Materials is a highly skilled process that requires experience working with natural building products and systems. It is the responsibility of the applicator to select the right product and system for the job and ensure correct installation and application according to the above and other relevant criteria.

Using a certified Artisan

ROCKCOTE has developed a certification program for licensed tradespeople in the architectural coatings field to be recognised as an artisan to work with our Natural Materials.

Artisans complete a two-day workshop followed by on site experience and have the most up-to-date information on application and usage of our products.

ROCKCOTE highly recommends the use of Certified Artisans for all projects using Decorative Finishes from our Natural Materials range. More about Becoming an Artisan or Natural Materials Workshops.

Natural Materials and Colour

ROCKCOTE Natural Material products are made with pure ingredients and are free from synthetic nasties and toxins, therefore colour consistency is not desirable nor possible when these products are used.

Being traditional natural products, ROCKCOTE Natural Materials will display their natural patina over time in different ways. Many of these products can be tinted with oxides, however colour consistency and accuracy will depend on a large variety of factors such as dispersing time, oxide type and drying times as well as polishing and burnishing techniques. ROCKCOTE strongly recommends a colour and finish sample be provided for sign off by the selected applicator or artisan prior to the start of each project.

Being natural products, slight colour changes occur from batch to batch. It is therefore important to order enough material for the entire project at the same time.

We've drawn inspiration from nature to develop a Colour Range for our natural materials.
