Convergent Pentra-Sil® (HD)

High-Performance Lithium Densifier for Harder, More Durable Concrete

Pentra-Sil® (HD) is a high-solids Nano-Lithium® densifier and hardener designed to penetrate concrete and increase surface hardness, abrasion resistance, and durability. It helps eliminate concrete dusting while improving resistance to everyday wear and staining.

Ideal for existing concrete surfaces and polished concrete applications, this penetrating formula can enhance the appearance of the surface and help prolong the life of polished finishes. Because it penetrates the concrete rather than forming a surface film, there is no film to peel or lift.

Key Features & Benefits

• High-Solids Nano-Lithium® Formula — Provides penetrating hardening and densification.

• Increases Abrasion Resistance — Helps concrete stand up to everyday wear and traffic.

• Reduces Dusting — Hardens the surface to help create a cleaner, easier-to-maintain floor.

• Improves Stain Resistance — Helps concrete resist stains and simplifies maintenance.

• Enhances Polished Concrete — Adds a slight sheen while helping prolong the finish of polished surfaces.

• Penetrating, Non-Film-Forming — Reacts within the concrete rather than leaving a film that can peel or lift.

• Helps Reduce Efflorescence & Surface Sweating — Supports a cleaner, more durable concrete surface.

• VOC Compliant — Meets applicable VOC requirements.

Harder Concrete. Better Performance.

Pentra-Sil® (HD) penetrates, hardens, and densifies concrete from within—helping create a more durable, dust-resistant, and easier-to-maintain surface.
