Why Choose Mapei Kerapoxy Adhesive:
-
Problem: Tiles slipping during wall installations?
Solution: Kerapoxy's non-sag formula holds tiles exactly where you place them—even on vertical surfaces. -
Problem: Harsh conditions compromising your adhesive?
Solution: With resistance to thermal shock, water, and chemicals, Kerapoxy Adhesive is built for Australia's most extreme environments. -
Problem: Tiling over uneven substrates or special tile profiles?
Solution: Apply up to 10mm thickness in one coat, filling tile backs and substrate voids for a seamless bond.
When to Choose Mapei Kerapoxy Adhesive Over Other Options:
- Choose Kerapoxy Adhesive over cement-based tile adhesives when: You need maximum bond strength in submerged or chemically aggressive environments.
- Choose Kerapoxy Adhesive over silicone or MS sealants when: A rigid, structural bond is required rather than a flexible joint.
- Kerapoxy Adhesive is particularly effective for: Swimming pools, commercial kitchens, stone façades, steel substrates, fibreglass pools, and installations on screeds or metal.
- Consider other Adheseal solutions when: You need flexible joint sealing (use Mapesil AC) or work on damp substrates (use Mapeproof or PU-based options).
How to use Mapei Kerapoxy Adhesive
- Essential Tools & Setup: Low-speed electric mixer, notched trowel, Pulicol 2000 (for hardened cleanup), gloves, and protective eyewear.
- Surface Preparation – The Key to Success: Ensure surfaces are dry, dust-free, and stable. Avoid wet or crumbling surfaces—use appropriate primers where needed.
- Pro Tips: Always mix full kits to maintain proper ratio. If retooling after application, do so within 45 minutes before material starts hardening.
Storage, Shelf Life, and Handling
- Storage: Store in sealed containers at 5–25°C. Avoid direct sunlight or extreme temperatures to maintain workability.
- Shelf Life: 24 months in original packaging.
- Handling: Use gloves and goggles. Part B is corrosive—clean spills immediately. Dispose of according to local Australian regulations.
Certifications and Compliance
- EN 12004 R2T Certified: Recognised European standard for improved reactive adhesives with no vertical slip.
- EN 12003 Tested: Complies with mechanical strength and durability requirements.
- Manufactured to strict Mapei quality control standards.
Frequently Asked Questions About Mapei Kerapoxy Adhesive
Q: Can I use Kerapoxy Adhesive in a swimming pool?
A: Yes, it’s ideal for submerged applications including fibreglass and tiled pools. Just ensure the surface is clean, dry, and cured before installation.
Q: How do I remove cured Kerapoxy Adhesive?
A: Once cured, it can’t be cleaned with water. Use Pulicol 2000 or mechanical methods to remove hardened residue.
Q: What’s the maximum thickness I can apply in one coat?
A: Up to 10mm thickness can be applied in a single coat without slump, even on vertical surfaces.
Q: Does it require a primer on metal or gypsum?
A: Yes. On metal, remove rust; for gypsum or plasterboard, use a primer like Mapei Primer EP or Eco Prim T for best adhesion.
