Moeller Stone Care HMK R155 Removes dirt, grout film, construction dirt, and light wax coats. Especially suitable for polished marble and granite. For use on all interior and exterior surfaces and finishes.


HMK® R155 is a superior, mild alkaline, concentrated cleaner for removing general construction dirt, emulsion paint, wax coatings, the residual film built up from regular cleaning products as well as oil, grease, and light cement film from all natural and artificial stone surfaces. HMK® R155 has been specially developed for use on polished and fine-honed marble, limestone, and travertine. Also works on bluestone, granite, ceramic, porcelain, and all other natural and non-natural stone or tile surfaces.  For interior and exterior use.


Instructions: If underfloor heating exists, switch it off and allow the surface to cool to room temperature. Apply HMK® R155 diluted with water (1:2 to 1:10) depending on the intensity of the dirt. Use a scrubbing brush, stiff hand brush, or a suitable pad to work HMK® R155 into the surface. Leave for about 10 minutes but do not allow to dry (if needed sprinkle a little water to keep the area wet). Scrub the area again and remove the dirty liquid. Afterward, flood and rinse the area thoroughly with clean water. Repeat the procedure as necessary. For stubborn stains, HMK® R155 can be used undiluted.


For periodic refreshing of surfaces and to remove protective films use HMK® R155 diluted about 1:20 with water. When using a wet vacuum we recommend that you add HMK® Z702 defoamer to the water to regulate the amount of foam.


Important: Do not apply in direct sunlight. Do not apply on plastic, polished or waxed wood and lacquered areas. If these areas are splashed, remove splashes immediately and rinse thoroughly with clean water.
