EWI-360 Fungicidal Wash EWI Pro 5l is an ideal product for killing mould, algae, lichen, and mildew to prepare a substrate prior to applying External Wall insulation (EWI) or render systems.

This product takes just 24 hours to kill all microorganisms on the substrate, including algae, mould and lichen.

You can apply the wash using either a brush, sponge or cloth.

EWI-360 Fungicidal Wash can be used internally or externally on many different surfaces including brickwork, stone, wood and plaster.

The active ingredient in EWI-360 is a Benzalkanium Chloride, a proven biocide.

EWI-360 is ready to use straight out of the bottle, but should be mixed within its container before use, it should not be diluted with water or any other material.

A 5-litre jerry can of the EWI-360 will cover between 20 – 30m2.

Do not add Fungicidal Wash to paints, primers or renders.

EWI-360 Fungicidal Wash 5l is a standalone product.


EWI Pro Render Cleaner Application:

 · One coat of EWI-360 Fungicidal Wash should be applied by a brush or spray machine to a damp (but not waterlogged) substrate.

 · Where there is an excessive amount of organic growth, apply two coats but allow the first coat to dry properly before applying the second.

 · After application, leave for 24 hours and then wash down the surface if it is to be rendered or decorated.

 · A 5 litre tub of the fungicidal wash will cover between 20 – 30m2.


Substrate Preparation:

 · Ensure that the substrate is clean, dry and dust-free.

 · Before application, remove all organic growth, dirt, dust, grease etc. with a stiff bristled brush.

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.
