EWI-065 One Coat Dash Cover (OCDC)

Do you live in a pebbledash property? Bored of it looking tired and dated? Can’t afford to remove the pebbledash? Our One Coat Dash Cover (OCDC) is the perfect solution to cover up old pebbledash and give your property a modern look.

OCDC is a breathable, lightweight and flexible solution to covering over pebbledash. OCDC can be applied up to 25mm thick in one pass and once dry provides a perfectly flat surface ready to render or paint. This product has a high air content and excellent tensile strength, providing a stable and durable base while allowing trapped moisture within the underlying pebbledash to escape. The finished result is a completely transformed and updated property!


The One Coat Dash Cover comes as a dry mix in 25kg bags. The bag needs to be mixed with 6.3 litres of clean potable water using an electric paddle mix. It is recommended the basecoat is mixed for 2-3 minutes to achieve the required consistency. OCDC is then ready for use. When hardened, the product should not be re-mixed with fresh material.


Before application, ensure that the pebbledash substrate is stable. Any loose pebbles should be removed, and the pebbledash should be primed using EWI-310 Universal Primer.

The OCDC can be applied up to 25mm thick in one pass, up to a maximum thickness of 50mm if applying more than one pass. The basecoat should be applied to the substrate using a plastering trowel or spray machine, and a Fibreglass Mesh should be embedded within it. We recommend the use of our Orange Fibreglass Mesh for thick-coat plasters and renders. OCDC can be applied in either a single pass or multiple layers, depending on how much is required to cover over the pebbledash.

Once set, you can choose to apply either paint or render finish!
