Proactive Troubleshooting
Scenario: Using on Sensitive Surfaces
Potential Outcome: Risk of etching or discolouration on polished marble or natural stone.
Adheseal Best Practice: Always perform a hidden spot test first and protect adjacent surfaces before application.
Scenario: Inadequate Rinsing After Application
Potential Outcome: Residual cleaner may leave streaks or compromise final appearance.
Adheseal Best Practice: Rinse thoroughly with clean water after scrubbing to ensure a completely clean finish.
Applications in Practice: Trade Scenarios
For Tilers (On-Site Applicator): Post-Grouting Epoxy Haze Removal
The Professional's Challenge
Epoxy grout haze left on tiles after installation can harden and become difficult to remove, risking damage if aggressive mechanical methods are used.
The Adheseal Solution
Apply UltraCare Kerapoxy Cleaner within hours of grouting and allow 15–20 minutes dwell time. Agitate with a Scotch-Brite pad, then rinse thoroughly to achieve a perfect, haze-free finish.
Best Practice Note
Work in manageable sections to prevent the cleaner from drying. Always check grout joints to ensure they remain intact after cleaning.
For Remedial Contractors (Problem Solver): Restoring Cured Epoxy Residue
The Professional's Challenge
Older epoxy grout stains are often resistant to basic cleaners, leading to prolonged downtime and potential surface damage.
The Adheseal Solution
For stubborn cured residue, use UltraCare Kerapoxy Cleaner with extended dwell time or repeat the cleaning cycle. For extreme build-up, follow up with UltraCare Epoxy Off Gel as per its TDS.
Best Practice Note
Perform a patch test first, especially on sensitive or unknown substrates, to confirm compatibility and prevent accidental surface damage.
Frequently Asked Questions
Can I use UltraCare Kerapoxy Cleaner on natural stone or polished marble?
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.
Do I need to dilute the product before using it?
No dilution required – UltraCare Kerapoxy Cleaner is ready-to-use. Apply it directly onto the affected surface, allow the recommended dwell time (15–20 minutes), then scrub and rinse thoroughly with clean water.

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.
Limitations & Safety
Product Limitations
Not suitable for polished marble, wood, or methacrylate baths — may cause etching or damage. Always test on a hidden area before full application.
Extended contact time on sensitive substrates can lead to surface dulling. Follow recommended dwell time and rinse thoroughly.
Safety & Handling Requirements
Personal Protective Equipment
Wear chemical-resistant gloves (nitrile or neoprene), long sleeves, and safety goggles when handling. Avoid direct skin or eye contact.
Ventilation Requirements
Use in well-ventilated areas. Ensure cross-ventilation when working indoors to maintain air quality and speed drying after rinsing.
Fire & Handling Precautions
Non-flammable under normal conditions, but keep away from food preparation areas and store in a cool, dry place away from direct sunlight.
