1.03 Terms and Definitions:

a) Architects-Designers: A licensed professional under contract with an owner and specifies the Architectural Details to be used.

b) Adhesive: A material applied to the back of a Promould® Detail which is used to attach the pre-coated Foam Detail to a suitable substrate.

c) Base Coat: The material applied to the shaped EPS foam core, providing a durable, flexible and whether resistant surface to apply specified primer coats and Finished. The Decorawall® trade name is "PROMOULD®" for the acrylic cementitious base coat used as a coating on Promould® Mouldings.

d) Back wrapping: Where a fiber-mesh being used with an application of base coat onto a EPS Detail, is pooled back from the full length of the DEtail and extended from the edges of the Detail onto an existing suitable substrate where the Detail is being applied to. The mesh from the Detail is then embedded within a proper base coat and finished, using a Finish-Coat.

e) Contractor: Qualified and experienced Contractor-Spplicator (sub-trade} installing Architectural Details.
