Bellinzoni Idea Black is a penetrating black pigmented colour enhancer and anti-stain protective designed for absorbent textured black and dark granite slabs. It covers surface defects, unifies colour, and shields stone from water, humidity, oils, greases, and fats without leaving a film. Prevents mold, mildew, freeze-thaw damage, and efflorescence. Apply to 800–1200 grit surfaces with brush or roller on completely dry slabs. Allow 48 hours drying time, then finish with final polishing heads. Coverage: 15–25 m² per application depending on texture and porosity. Always test first on a small area before full application.
