ROCKCOTE Earthen Render Coarse is a heavily textured render designed to deliver a thick natural, rustic clay finish. Clay is highly breathable and has the capacity to absorb odours and impurities in the air and to regulate humidity, thus providing a very comfortable and healthy living environment.
Suitable: for straw bale and other natural substrates but has good adhesion to many surfaces. Interior walls only. Can also be used as a base render for applying ROCKCOTE Clay Plaster Decor and Otsumigaki over. Can be used as a finish coat on wood fired ovens if protected from weather.
Appearance : is a thick matt render finish (3- 8mm build) that will hold large particles such straw and chopped hemp through to shells, coffee beans and glass or ceramic chips.
Colour: is an off-white colour. It can be tinted to a range of colours with powdered oxides. See Advice on tinting with oxides.
Odour: is nil
Durability: When dry, clay is a naturally dirt repellent surface. However, it can be clear coated with ROCKCOTE Repel for extra water repellency in vulnerable areas such as kitchens and exposed exterior walls.
Vapour Permeability: is superb. Clay allows surfaces to breathe and offers positive moisture regulating and mould inhibiting properties.
Application: is with a trowel, as for regular plasters and renders. May be applied by hand.
Preparation: see ROCKCOTE Systems Guide for the correct preparation and application procedure on different substrates.
Coats: 1 – 2 coats
Drying Time: 2 – 3 days
Coverage: 3m2/20Kg based on 3mm build
