Viaduct Blackbox for GP-2 Grout
Viaduct Blackbox for GP-2 Grout is a pre-engineered formulation system developed to help manufacturers produce consistent, smooth-finish, and durable tile grout for residential and commercial applications. Built on a controlled polymer-based formulation, it simplifies grout manufacturing while ensuring uniform colour, strong joint filling, and long-lasting performance.
Just open the Blackbox, mix it with the prescribed raw materials in the recommended ratio, and the complete GP-2 grout formulation is ready for production. No formulation trials. No colour inconsistency. No R&D investment.
This engineered system delivers excellent joint filling, reduced shrinkage, improved adhesion to tile edges, and consistent batch quality—allowing manufacturers to offer a reliable GP-2 grout suitable for internal and external tile joints. Easy to manufacture, simple to control, and trusted in performance, Viaduct Blackbox is the smart way to produce grout with confidence.
