ProtectGuard® HD Bluestone Sealer is the smarter way to protect your bluestone without compromising its natural beauty. Unlike generic penetrating sealers, this formulation is built specifically for natural basalt — avoiding the patchiness or discolouration often caused by reactive minerals in bluestone.
It creates a breathable, non-film-forming barrier that repels water, oil, dirt, food spills, grime, and even graffiti — while preserving the stone’s original appearance and grip. Perfect for high-traffic areas like paths, patios, public walkways, and around pools where slip-resistance is critical.
Used in both residential and commercial settings, this eco-friendly sealer provides long-lasting protection without any silicones, solvents or strong odours.
Why Choose ProtectGuard® HD Bluestone:
✔️ Designed specifically for natural bluestone and basalt
✔️ Prevents permanent stains — oil, red wine, foot traffic grime, etc.
✔️ Protects from graffiti — safe for up to 5 cleanings with GraffiGuard®
✔️ Non-slip — keeps surface texture and grip unchanged
