Unsightly grout lines detract from the finest tiling work. When projects demand flawless, custom-designed grout and bonds that combine high-end decorative aesthetics with unparalleled hygiene, Mapei Kerapoxy Easy Design delivers. This product ensures superior chemical resistance, acid resistance, and simplified cleaning, transforming tiled spaces into durable, attractive, and easily maintained surfaces.
Mapei Kerapoxy Easy Design was formulated to meet the demand for a versatile, highly aesthetic, and extremely durable epoxy grout and adhesive. It excels in environments where hygiene compliance, high chemical resistance, and decorative value are paramount. This two-component system features Mapei's innovative BioBlock technology, providing a bacteriostatic finish that actively prevents mould and bacteria proliferation. Unlike traditional cementitious grouts that can absorb water and foster microbial growth, or less specialized epoxy systems, Kerapoxy Easy Design provides a dense, non-absorbent, and chemically resistant finish that lasts.
Kerapoxy Easy Design offers excellent workability, featuring a creamy consistency that simplifies application and ensures faster finishing times compared to many traditional epoxy mortars. The product has a pot life of 45 minutes and an open time of 40 minutes as an adhesive, providing sufficient time for precise placement. For optimal results, ensure joints are clean, dry, and free from contaminants before application.
For cleaning, emulsify the freshly grouted surface with a cellulose sponge and plenty of water. If residual traces harden, UltraCare Kerapoxy Cleaner can be used for final cleaning. For stubborn, cured residues, UltraCare Epoxy Off Gel is recommended for effective removal.
Mapei Kerapoxy Easy Design is engineered for rigid grout lines and high-strength adhesive bonds in tiled surfaces where chemical resistance, hygiene, and decorative aesthetics are paramount. It is a dense, epoxy-based solution that forms a solid, unyielding joint. In contrast, Mapesil AC is a silicone sealant specifically formulated for flexible expansion joints and areas subject to movement. Where Kerapoxy Easy Design provides structural integrity and resistance to static forces, Mapesil AC accommodates dynamic movement, preventing cracking and failure in areas like perimeter joints or changes in plane. Use Mapesil AC where flexibility is needed to manage stress, and Kerapoxy Easy Design where a hard, unmoving, and highly resistant joint or bond is required.
For searches related to general-purpose chemical resistant tile adhesives or cement-based grouts, other Mapei products like Kerapoxy Adhesive or Ultracolour Plus may be more appropriate for those specific requirements.
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.
