Pentra-Pel™ (SI)

Advanced Penetrating Stain Protection for Concrete, Stone & Masonry

Pentra-Pel™ (SI) is a penetrating lithium-based stain guard designed to protect interior and exterior concrete, natural stone, and masonry surfaces. Its advanced chemistry penetrates the substrate to densify, seal, and repel, creating a durable protective barrier against water, oil, and staining while maintaining the substrate’s natural breathability.

Unlike film-forming sealers, Pentra-Pel™ (SI) provides protection without significantly changing the appearance or character of the surface. It is especially well suited for polished concrete and natural stone where preserving the original look is important.

Easy to apply and VOC compliant, Pentra-Pel™ (SI) combines durable surface protection with the benefits of patented Silicone Reactive Lithium® (SIR®Li) chemistry.

Key Features & Benefits

• Stain Protection — Creates a protective barrier that helps resist water, oil, and stains.

• Densifies & Hardens — Helps strengthen and densify concrete surfaces while improving surface durability.

• Silicone Reactive Lithium® Chemistry — Utilizes patented SIR®Li chemistry for penetrating protection and performance.

• Abrasion Resistant — Helps create a durable surface capable of withstanding everyday wear.

• Ideal for Polished Concrete — Protects without creating a visible film or altering the natural appearance of the surface.

• Freeze-Thaw Protection — Helps reduce the potential for moisture-related freeze-thaw damage.

• Water & Oil Repellent — Helps prevent liquids and contaminants from penetrating the substrate.

• Natural Appearance — Preserves the original look and character of concrete, stone, and masonry.

• Excellent for Natural Stone — Provides penetrating protection while maintaining the appearance of many natural stone surfaces.

• Breathable Protection — Allows moisture vapor to escape from the substrate, helping reduce moisture-related sealer issues.

• VOC Compliant — Formulated to meet applicable VOC requirements and may contribute toward applicable LEED® credits, where qualifying criteria are met.

Protection That Works Below the Surface

Pentra-Pel™ (SI) penetrates into the substrate rather than simply forming a surface film. The result is long-lasting protection that helps surfaces resist staining and moisture while maintaining their natural appearance and breathability.
