Natural Renders

ROCKCOTE's Natural Renders are authentic earthen renders made from clay and lime, compatible with modern and traditional construction methods. 

Our Natural Renders impart a textural warmth, honesty and authenticity, naturally. We combine modern technology and ancient methods to produce natural, durable renders.

Earthen Renders are a natural earthy loam colour and can be tinted with oxides onsite if required. Coloured sands, quartz, marble chips, dry straw, crushed glass and other decorative elements can be added to create stunning unique effects. 

ROCKCOTE Lime Plaster Basecote is specified as a base coat for ROCKCOTE Marrakesh and ROCKCOTE Lime Wash. However it can also be used as an interior or exterior lime render for heritage work giving the finish of a more vintage, older finish (where ROCKCOTE Marrakesh gives a more modern, polished finish). ROCKCOTE Velvetino is used as a base coat to address substrate imperfections in plasterboard prior to application of ROCKCOTE Venetian Plaster.

They are easy to use, contain no cement and are free of dangerous chemicals. They have low embodied energy (energy necessary for the entire product life-cycle) and are fully recyclable which means they can be returned to the earth after use. The natural composition also means that they can play an active role in improving internal air quality.


ROCKCOTE Earthen Render Coarse is a hard, durable render developed for straw bale buildings and other natural substrates. Our most heavily textured natural material, Earthen Render Coarse is a true earthen render applied in thick coats to deliver an authentic rustic, natural clay finish.

ROCKCOTE Earthen Render Medium is a natural material formulated to create a natural earth plaster finish over modern substrates. The medium formulation is produced without the coarse aggregates in Earthen Render Coarse, making it more suitable for use in conventional buildings where a smoother textured look is desired.

A fine grained lime plaster that can be used both interior and exterior including areas of high humidity such as bathrooms and laundries.It is not suitable for shower recesses, bath tubs or hand basins as a finished product. It will comply with regulations on the refurbishment and repair of heritage listed and architecturally sensitive buildings. Lime Plaster Basecote is composed of hydrated lime, natural aggregates and additives. It is an ideal base coat for ROCKCOTE Marrakesh.

ROCKCOTE Velvetino is a traditional lime plaster developed as a base coat to address substrate imperfections in plasterboard prior to application of ROCKCOTE Venetian Plaster. ROCKCOTE Velvetino delivers a fine levelling coat that effectively covers the textured appearance of plasterboard, evening out vertical lines and smoothing joints, creating an homogenous surface for the subsequent application of ROCKCOTE Venetian Plaster.
