Mapei Kerapoxy Easy Design is a two-component decorative epoxy grout for 1-15mm joints that can also be used as an R2T epoxy adhesive. It is designed for tiled walls, floors, showers, bathrooms, swimming pools and high-hygiene commercial areas where a smooth, non-absorbent, chemical-resistant finish is required.
Kerapoxy Easy Design combines RG-class epoxy grouting performance with R2T adhesive capability. The smooth finish, colour range and BioBlock technology make it especially suited to decorative and hygienic installations where cementitious grout may not provide the required resistance or appearance.
Complete cleaning while the epoxy is fresh. Use a wet cellulose sponge or suitable abrasive pad during finishing, and use UltraCare Kerapoxy Cleaner for final residue removal on compatible surfaces. Hardened residue is substantially more difficult to remove.
Choose Kerapoxy Adhesive when the main job is bonding tiles with a dedicated high-strength epoxy adhesive. Choose Kerapoxy Easy Design when the main requirement is decorative, chemical-resistant epoxy grouting with adhesive capability.

Yes, it creates surfaces that comply with HACCP systems and EC Regulation No. 852/2004 for food hygiene. Its non-absorbent, bacteriostatic finish prevents mould and microbe growth, ensuring a hygienic tiled surface.
No, Kerapoxy Easy Design mixed with MapeGlitter or Mapecolour Metallic is not suitable for swimming pools or external use. The standard product offers resistance for these applications.
Epoxy grouts like Kerapoxy Easy Design offer superior chemical resistance, mechanical strength, and zero water absorption compared to cementitious grouts. This makes it suitable for areas exposed to chemicals, high traffic, or requiring high hygiene, avoiding common grout failures.
Apply this product when temperatures are between +12°C and +30°C. Working outside this range can affect workability and cure performance.
Yes, it is classified as an R2T-class adhesive according to EN 12004, meaning it is an improved reactive adhesive with no vertical slip. It forms a strong, chemically resistant bond.
| Application | Key benefit | Primary trades |
|---|---|---|
| Hygienic environments (e.g., commercial kitchens, hospitals) | Ensures HACCP compliance and high hygiene levels with its bacteriostatic, non-absorbent finish. Certified ISO 22196:2011. | Tilers, commercial builders, food service contractors |
| Decorative interiors (e.g., showrooms, luxury bathrooms) | Achieves superior aesthetic finishes with uniform, UV-resistant colours and optional MapeGlitter/Mapecolour Metallic effects. | Tilers, interior designers, architects |
| Wet areas (e.g., showers, bathrooms, swimming pools) | Provides excellent resistance to moisture and strong mechanical bond, preventing water ingress and grout degradation. | Tilers, waterproofers, plumbers |
| Chemically exposed surfaces (e.g., laboratories, processing plants) | Offers excellent resistance to acids, alkalis, and solvents, ensuring long-term durability where other grouts would fail. | Industrial tilers, chemical plant operators |
| Adhering tiles and mosaics to various substrates | Delivers an R2T-class bond, providing high shear strength and no vertical slip for secure installations on many surfaces including fibreglass and PVC. | Tilers, mosaic artists, shopfitters |
| Repairing degraded grout joints | Restores integrity and appearance of existing grout, offering a durable and chemically resistant solution for refurbishment. | Renovators, maintenance contractors, tilers |
Clean joints thoroughly; remove dust, laitance, and fresh adhesive residues. Joints must be dry and free of contaminants.
Add component B into A and blend using a low-speed drill until a smooth, homogeneous paste forms. Mix only enough for 45 min working time.
Apply with a rubber float, pressing diagonally across joints. Remove excess and immediately wash with water using a damp cellulose sponge, rinsing frequently.
Spread with a notched trowel and press tiles firmly to ensure full coverage. Open time ≈ 40 min; adjustment ≈ 60 min (23 °C).
Allow ≈ 24 h for light traffic, ≈ 4 days before service, ≈ 10 days before pool immersion.
Pro Tip: For large floors, use a single-disc machine with white felt pad to assist final cleaning.
Warning: Causes severe skin burns and eye damage. May cause an allergic skin reaction. Very toxic to aquatic life with long lasting effects.
Wear close-fitting safety goggles or full face protection. Use protective gloves made of Polychloroprene (CR), Nitrile rubber (NBR), Butyl rubber (IIR), or Fluorinated rubber (FKM). Comprehensive skin protection with suitable clothing, e.g., cotton, rubber, PVC, or viton, is required. If exposure levels exceed workplace limits, use adequate respiratory protection.
Ensure adequate ventilation during use. Avoid breathing mist, vapours, or spray.
Store locked up, away from food, drink, and feed, in adequately ventilated premises. Component A should be stored at a minimum of +10°C to prevent crystallisation. Dispose of contents and container according to applicable local, state, and federal regulations. Avoid release to the environment.
Proper surface preparation is crucial for strong bond and durable grout performance, preventing common failures.
Surface prep: For grouting, joints must be dry, clean, free from dust, and empty to at least two-thirds of the tile thickness. Remove any adhesive or mortar seepage while fresh. Ensure installation mortar or adhesive has set and most moisture has evaporated. Joints must not be wet when grouting. For adhesive use, surfaces must be clean, dry, and structurally sound.
Primer: Not required. Kerapoxy Easy Design bonds directly to prepared surfaces.
Surface prep: Ensure surfaces are clean, dry, and free from contaminants. Roughening may be required to ensure mechanical key.
Primer: Not required. Kerapoxy Easy Design is suitable for direct application to these substrates.
Surface prep: Joints must be dry, clean, and free from contaminants. Ensure any prior adhesive has cured. Always conduct preliminary tests to assess potential staining or adhesion issues before full application.
Primer: Not required. Preliminary testing is critical for these surfaces to ensure compatibility and appearance.
