Modified silicone/acrylic base sealer that produces a tough, hard, and highly protective finish. For interior and conditional exterior use on honed and textured mineral surfaces.
HMK® S235 is 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 matte finish. HMK® S235 is UV resistant, and slip retardant. Facilitates regular cleaning and overall maintenance, especially on rough and textured surfaces.
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 underfloor heating exists, switch it off and allow the surface to cool to room temperature.
Instructions: Apply HMK® S235 generously and evenly to a chemically clean and dry surface with a natural bristle paintbrush or the HMK® Z950-HMK Z951 brushes and leave to dry. One or two even applications are usually sufficient, depending on the porosity of the stone and desired color enhancement. Do not allow to puddle. Repeat treatment after 12 hours if further color enhancement is desired.
Do not walk on the treated surface until 4 to 6 hours after treatment is completed. Protect the 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.
