HMK® R165 is a heavy duty acid based concentrated cleaner for removing grout and cement residue, construction dirt, persistent lime deposits and efflorescence from unglazed terracotta, clay tiles, brick & block paving, unglazed ceramic and porcelain tiles, concrete blocks, bricks and acid tolerant natural and artificial stone. Special inhibitors control oxidation of vanadium salts, manganese, pyrite and other metallic deposits commonly found in clay tiles and bricks. For interior and exterior use.
Note: Do not apply in direct sunlight. Acid-sensitive surfaces such as polished and fine honed marble & limestone, metal and plastics, etc. can be damaged by contact with acid base products like HMK® R165. For the removal of light construction dirt use HMK® R155 Intensive Cleaner -acid free- as an alternative.
Protect all adjacent surfaces. If under-floor heating exists switch it off and allow the surface to cool to room temperature. HMK® R165 should be diluted with clean water (approx. 1:2 to 1:10) depending on the intensity of the dirt. Working on manageable sized areas at a time, wet the surface to be treated before application and apply HMK® R165 to the wet surface and work in using a scrubbing brush, broom or a suitable pad. Let sit for a short time but do not allow it to dry, scrub the area again and remove the dirty liquid. After the application process is completed, clean the area thoroughly, using HMK® R155 Intensive Cleaner -acid free- diluted approx. 1:10 with clean water. Afterwards, rinse the area thoroughly with clean water. Repeat the cleaning procedure in the case of very strong contamination.
