HMK R147 Cement Film Remover – Cement Film Remover Concentrate for Professional Post-Construction Cleaning
After grouting or mortaring, matte films, limescale residues, or cementitious deposits often remain on tiles, porcelain stoneware, clinker, and stoneware. Normal cleaners are usually not sufficient because the residues are mineral-bound. HMK R147 Cement Film Remover is an acid-based special cleaning concentrate for the quick and reliable removal of cement film, mortar residues, limescale deposits, and construction dirt on all acid-resistant surfaces.
For tilers, stonemasons, and cleaning companies, HMK R147 is an extremely economical helper, especially for professional final post-construction cleaning. The concentrate can be flexibly dosed depending on the degree of contamination and is suitable for small renovation areas as well as larger commercial projects. Application can be done either manually or mechanically. The cleaner is free of hydrochloric and phosphoric acid, EMICODE-tested, and universally suitable for indoor and outdoor use.
Technical Data and Product Features:
- Product Type: Acidic special cleaning concentrate
- Application: Removal of cement film, mortar residues, limescale, and construction dirt
- Suitable Coverages: Porcelain stoneware, ceramics, tiles, stoneware, clinker, quartz composite
- Area of Application: Indoors and outdoors
- Processing: Manual or mechanical (ideally matched to cleaning machines, pads, and brushes from the Karl Dahm range)
- Acid Base: Free of hydrochloric and phosphoric acid
- Coverage: Approx. 5–30 m² per litre (depending on contamination and surface structure)
- Delivery Forms: Available in packaging units of 12 x 1 l and 2 x 5 l
Important Application Instructions and Practical Tips:
- Pre-wet the surface well: Before application, the entire surface should be thoroughly pre-wetted. This reliably prevents the acidic cleaner from soaking too deeply into the joints or porous areas.
- Processing: After a short contact time, agitate the dissolved residues with a brush, pad, or cleaning machine and then immediately absorb thoroughly with clear, clean water.
- Important Note: Never allow the cleaner to dry on the surface! Therefore, always work in sections on larger objects.
- Apply a test area: Always try the product on an inconspicuous test area first. This applies particularly to unknown coverings, polished surfaces, or mixed materials.
- Occupational Safety: Protective gloves, safety goggles, and suitable work clothing must be worn during application. Always ensure good ventilation in interior rooms.
- Caution with natural stone: HMK R147 is not suitable for acid-sensitive natural stones such as marble, limestone, or travertine. For these coverings, an acid-free cleaner, such as HMK R155 Intensive Cleaner, must be used.
FAQ – Frequently asked questions about HMK R147 Cement Residue Remover
For which materials is HMK R147 Cement Film Remover suitable?
HMK R147 is suitable for all acid-resistant coverings such as porcelain stoneware, ceramics, glazed and unglazed tiles, stoneware, clinker, and quartz composite.
The cleaner can be used on both wall and floor surfaces. A test area should always be created before full-surface application.
Can HMK R147 be used on natural stone?
HMK R147 must never be used on acid-sensitive natural stones such as marble, limestone, or travertine.
The acid contained can irreversibly attack the surface and cause matte spots. An acid-free intensive cleaner is the right choice for such materials.
Is the cement film remover suitable for outdoor use?
Yes, HMK R147 can be used without restrictions indoors and outdoors.
Typical areas of application are terrace slabs, clinker surfaces, driveways, or outdoor coverings directly after grouting. Adjacent, acid-sensitive components should be protected from splashes.
Can HMK R147 be processed mechanically?
Yes, the cleaner is optimized for both manual and mechanical application.
On larger surfaces, the use of a cleaning machine with a suitable pad or brush system significantly improves surface performance. After the cleaning process, the surface must be thoroughly neutralized with clear water.
Does the surface strictly need to be pre-wetted before application?
Yes, pre-wetting is absolutely necessary, especially with cementitious joints and absorbent edge areas.
This reduces the capillary absorption of the acidic cleaner into the joint. This protects the joint material and supports a more even cleaning effect.
What protective equipment is required during work?
Since it is an acidic concentrate, protective gloves, safety goggles, and suitable work clothing must be worn during processing.
Direct skin and eye contact must be strictly avoided.
Is HMK R147 allowed to dry on the tiles?
No, the cleaner must under no circumstances dry on the surface.
Dried residues can cause new streaks that are difficult to remove. Therefore, always work in manageable sections and absorb the dirty solution thoroughly with water immediately after the contact time.
