Application
HMK® S242 is a ready to use solvent based impregnator for use on all natural stone surfaces (soft and hard), agglomerates, reconstituted stone and terrazzo, and can be used on polished, honed and textured surfaces. By reducing water and dirt penetration, regular maintenance is facilitated. Algae, fungus and other problems occurring with exterior installations are reduced. Color enhancement will bring out the grain and structure of the stone. HMK® S242 is especially suited for wall and floor surfaces. Vapour permeation is only slightly diminished. Please note that HMK® S242 is not effective against oil and grease. For exterior and interior use.
Important: 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® S242 generously and evenly to a chemically clean and dry surface with a natural bristle paint brush. One saturating, wet-on-wet application is usually sufficient depending on porosity of the stone. Thoroughly remove excess before drying on the surface. For more absorbent surfaces additional applications may be required. Subsequent applications may be done within fifteen minutes of the initial application, but it is best to wait 24 hours between applications to best determine saturation level. Smears or imperfections left after the application process can be removed using a soft clean cloth moistened with HMK® S242 and buffing.
Do not walk on the treated surface until 4 to 6 hours after treatment is completed. Resistance to dirt and water is developed over 24 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.
