EWI Pro Top Coat Render Accelerator 100 ml EWI-020 

EWI Pro Top Coat Render Accelerator 100 ml is a high-quality liquid additive that can be used to accelerate the curing process of Silicone or Acrylic renders.. 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 works to speed up this curing process, allowing for faster job completion rate.

This product is suitable for colour-through textured renders and has no negative effect on their appearance.


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

EWI-020 should be poured directly into a bucket of our render. Thorough mixing with a plaster mixer is needed to reach a good, workable consistency. Mix 100ml of EWI-020 for every 25Kg bucket of render. Do not add water to the render.

It is recommended to follow the product data sheet and manufacturer’s instructions for working conditions and restrictions.

Safety Measures

Avoid skin contact and protect the eyes. In case of eye contact, wash the eyes abundantly with clean water and seek medical assistance. The use of gloves, goggles and protective clothing is recommended.
