For fresh cleaning during installation and removing post-lay epoxy residues, UltraCare Kerapoxy Cleaner is a ready-to-use liquid detergent that removes traces, marks, and stains of epoxy grouts without emitting hazardous fumes. It is formulated to clean porcelain, glazed ceramic, glass mosaics, and other non-absorbent surfaces without damaging the coating surface or the finished grout joints when used correctly.
What it does
This concentrated liquid detergent dissolves and lifts residues of all MAPEI epoxy grouts, including Kerapoxy, Kerapoxy CQ, and Kerapoxy Easy Design. It acts directly on the binder matrix to clean the face of the tile or mosaic during the installation process or as a final washdown after laying work is complete. The formulation is also suitable for cleaning epoxy residue from application tools before the grout cures. It carries a pH of 11, providing the alkaline action needed to break down epoxy films without attacking the underlying glazed ceramic or glass substrates.
Numbers that matter
- pH 11: High-alkalinity formulation provides the chemical action needed to break down stubborn epoxy binders without releasing hazardous fumes.
- Up to 15-20 minutes waiting time: The maximum standing window required for residues that have begun to set or have been on the surface for several hours.
- 0°C to +40°C application range: The allowable surface and ambient temperature window for cleaning operations.
- 36-month shelf life: Long-term storage stability when kept in its original, sealed packaging in a cool place.
Where to use it
The cleaner is suitable for removing epoxy residues on:
- Porcelain tiles
- Glazed ceramic tiles
- Glass mosaics
- Non-absorbent wall and floor surfaces
Limitations
- Do not use on polished marble or natural stone. For unpolished natural stone, perform a preliminary test on a hidden area first.
- Do not use on wood substrates or wood surfaces.
- Do not use on methacrylate baths.
- For materials with unknown surface resistance, test the product on a trial area before full application.
- For fully cured epoxy residues that have hardened over time, use UltraCare Epoxy Off Gel instead.
How to apply
UltraCare Kerapoxy Cleaner is supplied pre-diluted and ready to use; do not dilute with water. Protect all adjacent surfaces that could be damaged by direct contact with the liquid before commencing.
Apply the liquid directly onto the affected tiles or grout residues. For fresh cleaning, leave the solution to stand for a few minutes. For residues left for several hours, allow the cleaner to stand for 15 to 20 minutes; repeat the application cycle if residues persist. Work the surface using a Scotch-Brite pad to loosen the film. For large-scale flooring applications, a single-disc cleaning machine can be used. Wipe away the suspended residue solution and rinse the entire surface thoroughly with clean, fresh water.
Frequently asked questions
Can I use Mapei UltraCare Kerapoxy Cleaner on natural stone?
No, do not use this product on polished marble or sensitive natural stone without a preliminary test. Always conduct a hidden spot test first to check compatibility and avoid surface etching or discolouration before full application.
Do I need to dilute Mapei UltraCare Kerapoxy Cleaner?
No, this product is ready-to-use and requires no dilution. Apply it directly, allow a dwell time of 15–20 minutes, then scrub and rinse thoroughly with clean water.
Is ventilation important when using this cleaner indoors?
Yes, good ventilation is recommended when working indoors. While the product does not emit hazardous fumes, adequate airflow maintains safe air quality and assists with drying after rinsing.

Applying Mapei UltraCare Kerapoxy Cleaner: Enhanced Protocols & Best Practices
-
Step 1 – Surface Preparation
Remove excess epoxy grout from tiles or mosaics using a rubber float or sponge. Sweep or vacuum away dust and debris to allow the cleaner to work effectively.
Pro Tip: Always protect adjacent sensitive surfaces (e.g., natural stone, timber) before applying cleaner to avoid accidental splashes. -
Step 2 – Application
Spray or pour UltraCare Kerapoxy Cleaner directly onto the surface or grout haze. Spread evenly to cover affected areas.
Manual Cleaning
Use a Scotch-Brite pad or white nylon scrub pad to agitate the surface in a circular motion.
Machine Cleaning
For large areas, use a single-disc cleaning machine with a soft pad for uniform cleaning and efficiency.
Timing: Allow 15–20 minutes dwell time for fresh grout haze; extend dwell or repeat for cured residues. -
Step 3 – Rinse & Finish
Remove the cleaner and loosened residue using a damp sponge or wet vacuum. Rinse thoroughly with clean water until no product remains on the surface.
Pro Tip: Work in small sections and change rinse water frequently to prevent re-depositing residue.
Product limitations
- Not for: Polished marble or sensitive natural stone without prior testing, as etching or discolouration may occur. Not for wood or methacrylate baths.
- Extended contact: Prolonged dwell time on sensitive substrates can cause surface dulling. Adhere to recommended contact times and rinse thoroughly.
Safety and handling
Personal protective equipment
Wear chemical-resistant gloves (nitrile or neoprene), long sleeves, and safety goggles. Avoid direct skin or eye contact.
Ventilation
Use in well-ventilated areas. Ensure cross-ventilation when working indoors to maintain air quality and assist with drying after rinsing.
First aid
- Eyes: Immediately flush with plenty of water for at least 15 minutes. Remove contact lenses if present and easy to do.
- Skin: Wash with soap and water. Remove contaminated clothing. Seek medical advice if irritation persists.
- Inhaled: Move to fresh air. Seek medical attention if breathing difficulty or discomfort occurs.
- Swallowed: Rinse mouth thoroughly. Do not induce vomiting. Seek immediate medical attention.
Storage and disposal
Store in original sealed packaging in a cool, dry place away from direct sunlight. Product has a shelf life of 36 months when stored correctly. Dispose of waste in accordance with local regulations.
Substrate guide
Proper surface preparation ensures effective cleaning and prevents damage. Follow these guidelines for compatible surfaces.
Porcelain, Glazed Ceramic & Glass Mosaic Tiles
Surface prep: Ensure surfaces are free from loose debris and dust. Remove bulk epoxy grout mechanically before applying the cleaner to improve efficiency.
Primer: Not required. Apply cleaner directly, allow 15–20 minutes dwell time, then scrub with a Scotch-Brite pad and rinse with clean water.
Application Tools & Equipment
Surface prep: Remove major grout residue from tools. This allows the cleaner to target embedded or cured epoxy more effectively.
Primer: Not required. Soak tools directly in the cleaner to dissolve epoxy build-up. Scrub and rinse thoroughly. Repeat if stubborn residue remains.
