This liquid exposure agent, manufactured by Advanced Pebble Solutions LLC (APS) under model number APS-GRE-FL, is a water-based surface retarder designed for use with fresh concrete. It functions by delaying the setting of the surface mortar, allowing the aggregate to be exposed for decorative finishes or to create a bonding surface for subsequent concrete toppings. Specifically formulated for quartz finishes, this green-colored agent is typically spray-applied onto the concrete surface after the bleed water has evaporated. It ensures consistent aggregate exposure without the need for harsh acids or intensive mechanical methods, while the underlying concrete cures normally to full strength. The product is supplied in a 5-gallon container and is VOC-compliant and non-flammable.
