HMK® S239
Topical Stone Sealer – High Gloss Finish

Professional Use Recommended

- Not for use on Polished Stone Surfaces - NOT for wet or Exterior Areas - 

HMK® S239 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 high gloss finish. HMK® S239 is UV resistant. Facilitates regular cleaning and overall maintenance, especially on rough and textured surfaces.

Important: HMK® S239 will not be effective on most polished and very fine honed stones, glazed ceramic/ porcelain or non-absorbing surfaces. For internal use only. 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® S239 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. One or two even applications are usually sufficient, depending on porosity of the stone and desired color enhancement. Do not allow to puddle. Repeat treatment after 12 hours if further color enhancement is desired.

Drying time is about 4-6 hours. Protect surface from rain and humidity for 12 hours. Do not apply to rubber, plastics, lacquered or varnished surfaces and solvent intolerant materials. Remove all foodstuffs from the area to be treated before work is commenced. Once dry the residual material is not harmful to health. For regular cleaning and continued protection use HMK® P324 Liquid Stone Soap.
