Application
HMK® R163 is an acid based concentrated cleaner for removing cement and mortar residue, lime and calcium deposits, and heavy duty construction dirt from all acid tolerant natural and artificial stone, ceramic tiles, porcelain, brick, terracotta, clay tiled floors and rough concrete surfaces. Not for use on polished surfaces. Suitable for interior and exterior use. Use the milder HMK® R169 Exterior Stone Cleaner if acid fumes are a concern. Do not apply in direct sunlight. Acid-sensitive surfaces such as polished and honed marble, limestone, agglomerates and concrete products, plastics and certain metal surfaces can be damaged by contact with acid base products like HMK® R163. HMK® R163 is not suitable for latex/resin modified grouts; consider using HMK® R180 Stripper as an alternative.
Instructions
Protect all adjacent surfaces. If under-floor heating exists, switch it off and allow the surface to cool to room temperature. Dilute HMK® R163 with clean water (1:4 to 1:20) depending on the level of contamination. Wet the surface with clean water and apply HMK® R163 with a scrubbing brush, stiff brush or a suitable pad. Leave for a short time to work but do not allow to dry. Scrub the area again and remove the dirty liquid. Afterwards, clean the area thoroughly using HMK® R155 Intensive Cleaner -acid free- diluted with clean water (about 1:20) and remove the dirty liquid and then rinse the area thoroughly with clean water. Repeat the procedure in the case of very strong contamination.
