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.

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.
Benefits of Lime:
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)
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:
- 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.
