EWI-020 Render Accelerator 100ml is a special liquid additive used to reduce the curing process / drying time of External Wall Insulation (EWI) Systems and thin coat renders.

It accelerates the curing time of the coloured through textured renders, enabling faster completion of jobs and allowing users to install external wall insulation and render systems year-round.

Render Accelerator is an ideal product for use in low temperatures as well as fog.

If you live in a colder climate, where the drying process takes a long time, this product is a worthwhile investment.

It allows installers to continue to install thin-coat render systems throughout the winter months.

EWI-020 Render Accelerator is suitable for colour-through textured renders and has no negative effect on their appearance.


EWI-020 Render Accelerator Application:

 · Before applying the EWI-020, it is important to take appropriate Health & Safety measures.

 · EWI-020 should be poured into a bucket of our render.

 · Thorough mixing with a plaster mixer is needed to reach a good, workable consistency.

 · A typical mix of the EWI-020 is 100mm for every 25kg bucket of render.

 · It is recommended to follow manufacturer’s instructions for working conditions and restrictions.

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.
