FS Darkener Plus X is a ready-to-use, solvent-based stone treatment made with modified silanes that deeply penetrate natural stone surfaces. It enriches the stone’s natural colour, delivering a deep wet-look finish while providing superior resistance to oil, water, and stains.

Designed for long-lasting performance, it remains breathable and is ideal for both indoor and outdoor applications on granite, lime-based stones, silicate-based stones, and other dark-toned surfaces.

FAQs

How does FS Darkener Plus X compare to water-based color enhancers?

Solvent-based FS Darkener Plus X delivers deeper penetration and longer-lasting color enhancement than water-based alternatives. Its robust silane chemistry ensures superior stain resistance, oil repellency, and UV stability.


Perform a simple water-bead test: if water no longer beads, the oil-repellent, stain-resistant barrier has worn off. Reapply FS Darkener Plus X to renew your stone’s color intensification, waterproofing, and breathable sealer performance.


Clean periodically with a pH-neutral cleaner to avoid stripping the wet-look sealer layer. Reapply FS Darkener Plus X every 12–18 months as a stone color intensifier and stain-resistant protector to keep granite and marble surfaces looking richly saturated.


No, because it’s a breathable stone impregnation, not a film-forming finish, it maintains the natural texture and slip resistance of tile, stone slabs, and pool decks while providing waterproofing and stain protection.


Regularly clean with a pH-neutral stone cleaner to avoid stripping the wet-look sealer layer. For heavy-wear areas, reapply FS Darkener Plus X every 12–18 months to restore full stain resistance and color intensity on dark-colored stones.
