HMK® S731 Silane Impregnator is a ready-to-use penetrating sealer formulated to reduce water and dirt absorption in natural stone, concrete, and unglazed brick. It is suitable for both interior and exterior applications and helps protect surfaces while preserving their natural appearance.
The silane-based formulation penetrates into the material rather than forming a surface film, supporting vapor permeability and helping limit moisture-related damage over time.
Key Features
- Silane-Based Penetration: Absorbs into the substrate to reduce water and dirt uptake.
- Vapor Permeable: Allows treated surfaces to breathe and helps reduce trapped moisture.
- Wide Material Compatibility: Suitable for soft and hard natural stone, concrete, and unglazed brick.
- Interior and Exterior Use: Designed for use in a range of indoor and outdoor environments.
- Minimal Surface Impact: Leaves little noticeable change in surface texture or color.
- Freeze-Thaw Support: Helps limit moisture-related frost damage in exterior installations.
