What does Render Accelerator do?

Render Accelerator reduces the curing time of silicone and acrylic renders, allowing faster job completion and improved efficiency on site. It helps maintain the performance and appearance of the render while mitigating the challenges posed by cold or damp conditions. It’s important to note that Render Accelerator doesn’t cause the render to dry instantly. Instead, it protects the render surface during colder nights, helping it to set evenly and consistently.

Why should I use a Render Accelerator?

Using EWI-020 Render Accelerator provides several benefits: Enables rendering in colder weather conditions Reduces drying time by up to 50% Prevents the render from freezing overnight Maintains render appearance and performance Improves project efficiency and flexibility In short, it helps you stay on schedule even when temperatures drop below the ideal curing range for renders.

How do I use the Render Accelerator?

To use EWI-020 Render Accelerator, pour it directly into a bucket of render before mixing. Thoroughly mix with a paddle mixer to achieve a consistent texture. Mix 100ml of EWI-020 per 25kg bucket of render Do not add water to the mixture Mix until the render reaches a smooth, workable consistency This additive is suitable for all colour-through textured renders, such as EWI-075 Silicone Render, EWI-076 Premium Bio Silicone Render, EWI-040 Silicone Silicate Render and EWI-077 Nano Drex Silicone Render.

How much Render Accelerator should I use per bucket?

Only 100ml of EWI-020 Render Accelerator is needed per 25kg bucket of render. Using more than the recommended amount will not accelerate the drying process further and could affect the performance of the render.

Will Render Accelerator change the appearance of my render colour?

No, EWI-020 Render Accelerator has no negative effect on the colour or texture of silicone or acrylic renders. It is suitable for colour-through textured renders and maintains the original finish and tone.

Can I use multiple bottles in one bucket?

No, adding multiple bottles of Render Accelerator to one bucket will not make the render cure faster. The correct dosage is 100ml per 25kg of render. Using more than this will not enhance performance.

What are the best conditions for applying silicone render with Render Accelerator?

The ideal conditions for applying silicone render are: Temperature: Between 5°C and 25°C Humidity: Moderate levels are ideal Weather: Avoid direct sunlight, heavy rain or strong winds The substrate should also be within the same temperature range and dry before application. EWI-020 helps stabilise performance when conditions are less than ideal, especially during colder or more humid periods.

How should I store Render Accelerator?

Store EWI-020 Render Accelerator in its original packaging in a cool, dry place. It has a shelf life of up to 12 months from the date of manufacture.

This render remover is the business. Sorted out dried monocouche that looked stuck fast on the window glass and uPVC cladding. Safely cleaned both without a mark! Saved me a massive headache and cut the cleaning time in half just like the description says. It’s proper easy to use as well, no messing around with mixing, which is a doddle. Top value from the 5L container. Will order this every time now.

Good kit, shifts the dried stuff, but takes a minute longer. Spot on for getting dried silicone render off, which is the main thing I needed it for. The surface finish it left on the uPVC cladding was brilliant, came up looking new. Gave it four stars as it did take longer than advertised that '1-minute' general clean felt more like 3 or 4 minutes for me, and I needed an extra pass on the medium soiling patch. Also, noticed it struggled more on the deeper monocouche spillage compared to the silicone render on the same wall. You have to keep it wet; it dries too quick in any kind of breeze on a site, which is a bit of a faff. Overall, happy with the purchase, it delivers on the core promise efficiently. Only complaint for a trade user is that the 5L container is a little too bulky to be hauling around on a ladder set up.

Brill stuff for shifting silicone off the uPVC. Worked quickly as it's RTU, but the price is high and that smell is a killer. Needed a second application on some bad spots.
