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.
- 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.
