Pentra-Sil H – 5 Gallon Pail
Pentra-Sil H is a Nano-Lithium concrete hardener and densifier formulated for freshly placed concrete and existing cementitious surfaces. Designed for tilt-up construction and power-troweled slabs, it penetrates deeply into the concrete surface, forming insoluble calcium-silica-hydrate for improved abrasion resistance, reduced dusting, and increased durability. The fast-drying, one-coat application creates a dense, breathable surface that resists water, stains, and efflorescence while remaining VOC compliant and easy to maintain.
Key Features
- Penetrating densifier that creates hard, dustproof surfaces.
- One-coat application with no rinsing required.
- Breathable finish with no film to peel or lift.
- Reduces efflorescence and surface sweating.
- Compatible with colored concrete, stains, and dyes.
- Allows curing compounds to be more easily removed.
- VOC compliant; may contribute to LEED points.
- Easy soap-and-water cleanup of tools.
Applications
- Freshly placed, power-troweled concrete slabs.
- Tilt-up construction panels and floors.
- Parking garages, warehouses, and distribution centers.
- Food processing plants, bottling facilities, and freezers.
- Healthcare facilities, laboratories, and office buildings.
- Sidewalks, driveways, loading docks, and common areas.
- Stadiums, schools, retail centers, and restaurants.
