Masonry Stone Wool Dash System
The Wetherby Stone Wool Dash System is a staple in Local Authority refurbishments, offering a resilient, waterproof finish on masonry substrates.

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.
