Akemi Darkener Super — Colour-Intensifying Stone Impregnation
AKEMI® Darkener Super is a ready-to-use, solvent-based impregnation that intensifies colour shades exceptionally well. Drawn into the pores by the stone’s own capillary action, it deepens and enriches colour while helping to even out damaged areas such as hairline cracks for a more homogeneous appearance. It is especially suited to dark and black stone — such as Nero Assoluto, Impala Black, and Galaxy — and works on fine-ground, ground, satin-finished, antique, and polished surfaces. After hardening it is harmless on contact with food (certified by an external German testing institute).
- Deep colour intensification — enriches dark and black stone
- Penetrating impregnation — absorbed into the pores by capillary action
- Evens out hairline cracks for a more homogeneous look
- Food-safe after hardening (externally certified)
- Indoor & outdoor — weather-resistant, long-term effect
