One Coat Render EWI-265 – 25kg


One Coat Render (OCR) is a cement-lime wall coating, designed for creating a smooth surface on a range of substrates. This particular render is ideal for application using a spray machine, as it is very easy to process. The product is applied in just one pass before a Fibreglass Mesh is embedded within it to enhance the tensile strength. Once set, OCR can be painted to achieve a decorative finish or a thin coat render can be applied on top for a high-performance topcoat finish.

Intended Uses

One Coat Render is intended for creating a smooth surface on external walls, prior to applying a decorative finish. The render comes as a dry-mix and therefore requires the addition of water. OCR is ideally applied using a spray machine into brickwork, blockwork, concrete/reinforced concrete, autoclaved aerated concrete and silicate blocks.

Application Conditions

  • One Coat Render should be applied in temperate weather and should not be used in temperatures above 30°C. Likewise, if the materials or the substrate are frozen, or if there is any risk of frost damage within the first 24 hours, work should be postponed.
  • One Coat Render should not be applied in rain or humid conditions, or if wet weather is expected before the render has set.
  • Setting time is dependent upon environment and humidity. OCR will reach optimal strength after 28 days.
