Welcome to the Bunnings Workshop community. Thank you for joining us and sharing your question about painting your pebblecrete driveway.
One of the products suggested in this discussion - Re-surfacing pebblecrete was Megatreat. It is a two-part application of primer and topcoat. These products need to be ordered at your local store's Special Orders Desk. Unfortunately paving paint and garage paint systems are not compatible with pebblecrete.
