EWI-020 Render Accelerator

Product Overview
EWI-020 Render Accelerator is a ready-to-use additive designed to speed up the curing and drying times of Premium Bio Silicone, Silicone, Silicone Silicate and Nano Drex Silicone Renders. By improving curing performance in lower temperatures, it helps reduce the risk of application issues associated with slow or incomplete render set. While particularly useful in colder conditions, the accelerator is intended to support consistent and reliable curing whenever site conditions may otherwise impact programme times.
Intended Uses
EWI-020 Render Accelerator is used to aid the curing of thin coat render systems where reduced temperatures or challenging site conditions could affect performance. It allows installers to maintain productivity and continue using silicone-based render finishes throughout the year without compromising the quality or long-term performance of the render.

The accelerator should be poured directly into the render bucket and mixed thoroughly before application. A dosage of 100 ml per 25 kg bucket of render is recommended. EWI-020 is supplied ready to use in 100 ml bottles and does not affect the performance or finish of the render when used at the recommended rate.
