EWI-065 EWI-Pro One Coat Dash Cover OCDC Pebbledash is a durable, vapour permeable, lightweight and flexible solution to covering over pebbledash that provides a perfectly flat surface ready to render or paint.

OCDC Pebbledash One Coat Cover EWI-065 can be applied up to 20mm thick in one pass or up to 25mm thick in one pass if machine applied.

EWI-065 EWI-Pro is intended for use as a basecoat for applying on top of pebbledash surfaces and then can be painted or rendered to refurbish the look of the property and achieve the desired finish

One Coat Dash Cover OCDC EWI-065 contains lime, which provides a stable and durable base while allowing trapped moisture within the underlying pebbledash to escape.

The finished result of using Lightweight EWI-065 One Coat Dash Cover is a completely transformed and renovated property for years to come.

One Coat Dash Cover (OCDC) is the perfect solution to cover up old pebbledash and give your property a modern refurbished look.

EWI-065 comes as a dry mix powder in 25kg bags and should be mixed for 2-3 minutes with 5 litres of clean cool water (use an electric paddle to mix the product thoroughly to achieve the required consistency).

Depending on the conditions of application and the mixing process, check the first batch of mortar when it is mixed for the appropriate consistency and if necessary, adjust the amount of added water to the mixture.

Hardened basecoat should not be remixed with fresh material.




Nominal thickness: 5mm - 50mm 

EWI-065 One Coat Dash Cover OCDC: approx. coverage 1.15m2

Mixing time: approx. 2-3 minutes

Mixing ratio: 5 litres per 25kg bag

Application: Plastic, metal, felted float or Machine

Weight: 25kg

Consistency: dry mix powder


EWI Pro EWI-065 One Coat Dash Cover Application:

 · Apply the mortar uniformly across the substrate and level it with a plastering trowel.

 · When plastering in single coats of approx. 5-20mm, the final float finish (using a plastic, metal or felted float) should be completed after the initial setting process (approx. 2 hours for primed substrates, approx. 1.5 hours for substrates with a rough coat).

 · When plastering in multiple coats, each subsequent layer should be applied after the previous layer has set and therefore provided a natural key.

 · All plaster works should be carried out in dry, mild weather.

 · For external application, always consider scaffold netting and appropriate protection for the working surface to mitigate the impact of adverse weather conditions.


Substrate Preparation for OCDC Pebbledash Cover:

 · When using the EWI-065 OCDC as a levelling layer on top of pebbledash, ensure the substrate surface is clean and free from any debris, salts and dust.

 · All loose pebbles should be removed before application, and the EWI-310 Universal Primer should be applied to ensure stability.

 · For painted surfaces, check for structural stability first, then use EWI-310 Universal Primer, which will create an abrasive surface ready for the EWI065 OCDC to key onto.


EWI-065 Certification and Standards:

 · PN-C-81913:1998 Dispersion paints for façade painting.

 · European Technical Approvals ETA – 15/0576 and ETA – 15/0575.

 · BBA Approval Inspection Testing Certificate 18/5503.

No matter whether you choose a local installer or a national company, there’s a few tips to help you find the right installer for your home insulation improvements, such as asking for recommendations and making sure that they’re part of a certification scheme. This makes sure that they have the right skills and standards of workmanship to carry out the installation, and you can be sure that they know exactly what they are doing.


1. Thermal inspection picture in portfolio

It’s worth seeing a installer’s previous work. There’s no harm asking if you can see any properties nearby that they’ve installed insulation in. Best way would be to see Infrared Thermal Imaging Inspections. Thermal cameras spot small, but key changes in temperature in different areas of a house, identifying problematic areas that the human eye never could and some that a visual inspection could only hypothesize.

2. Reviews

Along with checking recommendations and previous work, finding reviews online can often be a great way to find out if they provide a good service or not. However, it’s best not to solely rely on reviews you may find or review websites, as there’s no controlling who writes them.

3. Compare prices

Comparing prices will also ensure companies can’t take advantage of you and give you a fair price. 

4. Word of Mouth

The best way to find a great insulation installer is through recommendations. Make sure you ask friends and family. They will most likely give you their honest opinion and can tell you from first hand experience.


Whether you require a wall, cladding, external wall, loft or floor insulation fitted, you can find and hire your local insulation installers from popular UK web pages. A simple internet search will return thousands of potential installers near your area.
