EWI Pro EWI-269 Lightweight Basecoat 25kg is a grey dry mix powder manufactured from a mixture of Portland cement, hydrated lime and perlite that can be used internally or externally on high performance blockwork, lightweight masonry structures and stonework.

The Lightweight Basecoat EWI-269 is a breathable, lightweight and flexible levelling compound that can be hand or machine applied to the substrate and can be applied up to 20mm in one pass.

EWI-269 Basecoat has a unique chemical composition with declared thermal efficiency of 0.47W/mK. 

This heritage-friendly EWI Pro lightweight basecoat provides a strong, flexible and waterproof layer.

Lightweight Basecoat can be applied in a thick layer, it is ideal for use with fibreglass rendering mesh roll.

EWI-269 Lightweight Basecoat Render comes as a dry mix powder in 25kg bags and should be mixed with 5 litres of clean cool water.

EWI-269 Lightweight Basecoat: approx. coverage 5m2

Mixing time: approx. 2-3 minutes

Mixing ratio: 5 litres per 25kg bag

Application: by hawk and trowel

Weight: 25kg

Consistency: dry mix powder


EWI Pro EWI-269 Basecoat 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.

 · Internal areas should be well ventilated to allow the application layer to cure and dry out.


Substrate Preparation for EWI-269 Lightweight Basecoat:

 · When using the EWI-269 Lightweight Basecoat as a levelling layer, ensure the substrate surface is clean and free from any debris, salts and dust.

 · If the surface is dusty prior to starting the installation process, then consider using a jet wash first before coating the surface with the EWI-301 Substrate Primer.

 · For painted surfaces, check for structural stability first, then consider using EWI-310 Universal Primer, which will create an abrasive surface ready for the EWI-269 Lightweight Basecoat to key onto.

 · For internal or external new build application, we recommend a period of settlement and drying out of the underlying substrate.

 · Substrates ready for the application of the Lightweight Basecoat should be durable, rigid and dimensionally stable to avoid applying the product thicker than necessary. 


EWI-269 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.
