About This Product
Color-Enhancing Penetrating Sealer
HMK® S748 Stain Protection – Premium Color is a ready-to-use, solvent-based oleophobic impregnating sealer that enhances the natural color and structure of absorbent stone surfaces while helping reduce the penetration of water, dirt, oil, and grease. The penetrating formula provides long-lasting stain protection without forming a surface coating and is suitable for both interior and exterior applications.
Protection for Natural Stone, Artificial Stone, and Terrazzo
HMK® S748 is designed for absorbent natural stones, artificial stones, and terrazzo, including polished, honed, and textured marble, limestone, travertine, granite, gneiss, agglomerate marble, and Solnhofen slabs. The sealer helps simplify routine maintenance by reducing staining and making dirt easier to remove while preserving the natural appearance of the surface.
Breathable, Food-Safe Formula
The sealer does not yellow with age and only slightly affects the natural vapor permeability of treated materials. Once cured, the remaining material is approved for contact with foodstuffs under the German LFGB standard, making it suitable for many residential and commercial stone applications.
Long-Lasting Performance
Service life depends on the surface absorbency, level of saturation, traffic conditions, and maintenance practices. Under normal conditions, HMK® S748 provides protection for several years and can be reapplied when the surface requires renewed protection.
