Ferrocem 528 is a free-flowing grout specifically designed for very narrow tile joints (0.2-3 mm). It contains a special additive that prevents the growth of black mold and bacteria.

Made from Portland cement, silica powder, and special chemicals, Ferrocem 528 ensures the grout won't peel off or crack. It's suitable for both interior and exterior use on floors and walls with large format tiles laid very close together, such as granite tiles.
