Pentra-Pel™ (SI)



Pentra-Pel™ (SI) is a surface-impregnating based stain guard designed for interior or exterior concrete, stone and masonry surfaces. This two component product provides a protective barrier that resists staining and creates an abrasion resistant, easy-to-clean surface. It densifies, seals, and repels while maintaining breathability and doesn't alter the appearance of the substrate.

Pentra-Pel™ (SI) combines the benefits of Nano-Lithium® silicate densification with silicon reactive chemistry (SiRE)™ for superior stain protection. This penetrating sealer produces a water repellent, less porous surface to keep out aggressive salts, such as chlorides and sulfates. Pentra-Pel™ (SI) may be used at the end of the polishing process in place of traditional film-forming guard products. This treatment is easy to use and is VOC compliant.
