Earthen Render Coarse

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 that is applied in thick coats to deliver an authentic rustic, natural clay finish.

It is designed to be used as a base coat render which can be overcoated with finish coats of any other ROCKCOTE natural material (Lime Wash, Clay Plaster Decor, Venetian Plaster and Marrakesh). 

Earthen Render Coarse is also ideal as a final finishing coat for straw bale projects. Ideally, slip coats and second coats should be applied with clay from the site. Earthen Render Coarse is then applied as a nice, even 3-4mm finishing coat, offering consistency of product, ease of application and a more even finished coat.

ROCKCOTE Earthen Render Coarse can also be used as a finish coat for ROCKCOTE Traditional Wood Fired Ovens.
