About This Product
Gloss-Enhancing Surface Sealer for Natural Stone
HMK® S239 Stone Sealer – Gloss Finish is a modified silicone/acrylic surface sealer that produces a tough, hard, protective finish while enhancing the natural color and structure of stone. It creates a high-gloss appearance while helping reduce the penetration of water, dirt, and grease into absorbent surfaces.
Compatible Stone and Masonry Surfaces
This ready-to-use sealer is suitable for interior honed, brushed, sandblasted, flamed, and riven natural stone, agglomerates, concrete, and terrazzo. Its UV-resistant formula helps maintain the enhanced appearance while making routine cleaning and maintenance easier, particularly on rough and textured surfaces.
