For tiled walls, floors, and swimming pools where standard cementitious grouts degrade, Kerapoxy Easy Design Grout and Adhesive provides a chemical-resistant, bacteriostatic epoxy barrier. This two-component reactive resin formula is engineered for areas with high hygiene requirements, such as showers, bathrooms, thermal facilities, and commercial showrooms, bonding to traditional construction substrates as well as fibreglass and PVC.
Kerapoxy Easy Design Grout and Adhesive functions as both an RG-class grout (EN 13888) and an R2T-class adhesive (EN 12004) with no vertical slip. Formulated with glass micro-spheres, it cures to a smooth, non-absorbent finish that resists commercial cleaning agents, acids, and alkalis. The integration of BioBlock technology prevents the formation and proliferation of mould and bacteria on the grout surface, making it suitable for food-preparation environments in compliance with the HACCP system and EC Regulation No. 852/2004.
This system is suitable for internal and external installations across several demanding trade scenarios:
The pre-dosed packages must be mixed in their entirety; do not estimate or split quantities, as incorrect catalysing ratios compromise the hardening process. Apply the mixed paste at temperatures between +12°C and +30°C using a rubber grout float, ensuring joints are filled to the bottom.
Cleaning must be completed while the grout is still fresh. Emulsify the residue with a wet cellulose sponge, or use a Scotch-Brite abrasive pad for rough or structured tiles. UltraCare Kerapoxy Cleaner may be used for final cleaning. Hardened residues cannot be cleaned with water and must be removed mechanically or with Pulicol 2000 and UltraCare Epoxy Off Gel.
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.
