One Coat Render (OCR) is a cement-lime coating that is designed to create a smooth surface on external walls before applying a decorative finish. It is intended to be applied using a spray machine which can be achieved in just one pass. Once applied, OCR is embedded with a Fibreglass Mesh to enhance its tensile strength. Then, once set, OCR can be coated with paint to achieve a decorative finish or a thin-coat render to enhance the durability of the topcoat finish.
One Coat Render is intended for creating a smooth surface on a substrate before applying a decorative finish. The render comes as a dry mix; therefore, it requires mixing with water. OCR is ideally applied using a spray machine onto brickwork, blockwork, concrete/reinforced concrete, autoclaved aerated concrete and silicate blocks.
