About This Product
Premium Impregnating Sealer for Stone Surfaces
HMK® S234 Stain Protection - Extra is a solvent-based impregnating sealer formulated to protect natural stone, artificial stone, terrazzo, and agglomerates from water, dirt, oil, and grease. The penetrating formula helps reduce staining while maintaining the natural appearance of the treated surface.
Protection Without Changing Surface Appearance
S234 penetrates below the surface to provide long-lasting stain resistance without forming a surface film. Treated surfaces remain vapor permeable and experience little to no aesthetic enhancement, making it suitable for polished, honed, and textured finishes.
Interior and Exterior Stone Applications
Suitable for both interior and exterior installations, HMK S234 is food hygiene compliant and can be used on countertops, floors, walls, and other stone surfaces where resistance to oil, grease, water, and everyday contaminants is important.
