SpecHard – Intraseal 
Water-based siliconate sealer/densifier
SpecHard-Intraseal is a water-based silicate/siliconate sealer/densifier that significantly enhances the durability and appearance of concrete floors exposed to pedestrian and vehicle traffic. This proprietary, colorless blend of silicates and siliconates effectively penetrates concrete surfaces to seal, densify, and harden them, extending their lifespan and reducing maintenance costs. It is environmentally friendly, VOC compliant, and odorless, making it a safe choice for various applications. SpecHard-Intraseal is designed to resist dusting for years, offering a low sheen that beautifies the concrete surface without altering its non-slip texture.
