More Details About Project A common challenge for architects is how to combine multiple finishes into the interior of a project, especially if they are unlike materials. In this project's case, the architect wanted to achieve a look of cast stone on all the door surrounds and base moulding (like cast stone) but have the appearance of stone continue to the light coves in the ceiling bays. Echo-Stone was used since it can be cast in a solid form for the cast stone applications, but also sprayed for the thin wall light cove applications. The critical element is the identical texture and color regardless of the location was needed to give continuity. Echo-Stone was the answer to this hotels design challange.
