Broadcast Systems

     Petra’s Natural Quartz system is multi-coat broadcast system that is applied over mechanically scarified (shot-blasted) surfaces. The  Single Broadcast System is typically 55-60 mils thick, and Double Broadcast Systems are generally 80-100 mils thick. These floors have a textured finish that provide an even, non-skid surface. Natural Quartz systems have one or more base coats of pigmented 100% solids epoxy that receive full broadcasts of natural quartz aggregate. Once the broadcast coats have cured and the remaining loose aggregate has been swept off and vacuumed, a top coat of pigmented 100% solids epoxy is applied to seal in the aggregate and set the level of texture desired for the floor.  Finally, a top coat of aliphatic urethane is applied for added UV stabilization and gloss retention, and chemical resistance.  This system is often installed with and integral cove base in areas where seamless transitions are required from floor to wall surfaces. Natural Quartz floors are very durable, and offer much higher scratch and impact resistance than standard rolled on epoxy systems.
