EWI-265 One Coat Render (OCR)

EWI Pro’s One Coat Render (OCR) is a cement-lime render, designed to be applied in one pass to achieve a smooth, flat surface before the application of masonry paint. This product comes readily prepared in 25kg bags so that you get the perfect mixture every time. Simply mix the product with water and it is ready to apply.


One Coat Render comes as a dry mix in 25kg bags. The bag needs to be mixed with 5.5 to 6 litres of clean potable water using an electric paddle mix. It is recommended the render is mixed for 2-3 minutes to achieve the required consistency. OCR is then ready for use. When hardened, the product should not be re-mixed with fresh material.


Before application, ensure that the substrate is clean and free of dust, debris and paints. One Coat Render (OCR) can be spray applied or applied by hand to achieve a thickness of 10-15mm. Fibreglass Mesh should be embedded within the render during this stage of application. The desired effect should be a smooth surface, which, once dry, can be painted using Silicone Paint to achieve a decorative finish.
