Masonry Enhanced EPS Dash System

The Wetherby Enhanced EPS Dash System is a staple in Local Authority refurbishments, offering a resilient, waterproof finish on masonry substrates. In combination with the Enhanced EPS insulation, Dry Dash provides a high-impact , durable, low maintenance finish which has a proven track record in the UK.

Known as spar dash, pebble dash, or dry dash, it provides durability and freshness. The aesthetic outcome of any dash project greatly relies on the dashing mortar colour paired with a complementary aggregate.

Wetherby Dry Dash Finish is versatile, suitable for full elevations or in combination with other Wetherby finishes like brick effect render or brick slip. It’s perfect for render-only projects and final touches on external wall insulation systems.
