HMK® R163 – Cement Film Remover

HMK® R163 – Cement Film Remover

Heavy-Duty Acid-Based Cleaner for Cement, Grout & Lime Deposits

HMK® R163 is a professional-grade, acid-based concentrated cleaner designed for removing cement film, mortar residue, lime scale, efflorescence, and heavy construction dirt from acid-tolerant natural and artificial stone, ceramic tiles, porcelain, brick, terracotta, clay tile floors, and rough concrete surfaces.

⚠️ Not for use on polished or acid-sensitive surfaces such as marble, limestone, agglomerates, concrete products, plastics, or certain metals. For milder cleaning with fewer fumes, consider HMK® R169 Exterior Stone Cleaner. For latex/resin-modified grouts, use HMK® R154 Stripper / Stain Remover instead.

Directions for Use

1. Preparation: Protect adjacent surfaces. If underfloor heating exists, switch it off and allow the surface to cool. Pre-wet the surface with clean water.

2. Dilution: Mix HMK® R163 with clean water (1:4 to 1:20 depending on contamination level).

3. Application: Apply using a stiff brush, scrubbing brush, or suitable pad. Allow to work briefly, but do not allow to dry.

4. Cleaning: Scrub the area again and remove the dirty liquid.

5. Aftercare: Clean thoroughly with HMK® R155 Intensive Cleaner (acid-free) diluted 1:20, then rinse well with clean water.

6. Repeat if necessary for stubborn contamination.

💡 Pro Tip: When using a wet vacuum, add HMK® Z702 Defoamer to control foam.
