Craftsmen Specification 4 – Large Ground Profile ( US Patent Numbers : 7,614,820 B2 , 8,079,775 B2 ) Was first introduced on museum projects . This specification and these patents permit interior type finishes to be used on exterior applications without the hazard of slip and falls using a structural concrete mix that is embedded with surface-applied select materials then ground smooth to expose the aggregates and remove grind marks then washed with acid to create a non-slip ADA profile . The ability to pour greater volumes allows lower pricing . This accompanied with its unique look has spurred its popularity . Large Ground Profile is currently being used on all types of projects and makes the perfect transition from interior to exterior space .
