EWI-221 Rapid Set EPS Basecoat is a fast-setting, versatile adhesive designed for time-critical applications where efficiency and reliability are essential. Suitable for use both as a basecoat reinforcement layer and for fixing EPS insulation boards to the substrate, it delivers a compact, durable and waterproof finish with accelerated setting times. While it performs reliably in cooler conditions, its primary benefit is enabling faster programme turnaround, making it ideal for projects where time constraints are a key consideration throughout the year.
