HMK® S237 Stone Sealer – Satin Finish


SKU: HMK-S237 Category:


Modified silicone/acrylic base sealer that produces a tough, hard, and highly protective finish. For use on interior honed and textured mineral surfaces.

HMK® S237 is a ready to use color enhancing surface sealant that reduces the penetration of water, dirt and grease into honed, brushed, sandblasted, flamed and riven soft and hard natural stone surfaces, agglomerates, concrete and terrazzo. The color and structure of the surface will be enhanced while leaving a satin finish. HMK® S237 is UV resistant and slip retardant. Facilitates regular cleaning and overall maintenance, especially on rough and textured surfaces. For internal use only.

Important: Do not use in wet areas or on polished, glazed or non-absorbing surfaces. Clean surface thoroughly before treatment using HMK® R155 Intensive Cleaner (diluted) followed by a flood rinse with water and allow at least 24 hours to dry (max residual moisture of 2-4%) before sealing. If under floor heating exists, switch it off and allow the surface to cool to room temperature.

Instructions: Apply HMK® S237 generously and evenly to a chemically clean and dry surface with a natural bristle paint brush or the HMK® Z950-HMK Z951 brushes and leave to dry. Do not allow to puddle. Repeat treatment after 12 hours if further color enhancement is desired. One or two even applications are usually sufficient, depending on porosity of the stone and desired color enhancement.
