Product Definition
Bottled Waterborne Epoxy Colored Sand is a two-component joint filler engineered for premium architectural finishes. Built on a waterborne epoxy resin base with natural quartz aggregate (Mohs hardness 7-8) and an eco-friendly amine hardener, it eliminates the solvent emissions, mold issues, and aesthetic limitations of traditional cement and polyurethane grouts.
Core Technical Specifications
| Property | Value | Standard / Certification |
|---|---|---|
| VOC content | <30 g/L | French A+ Certified |
| Abrasion resistance | Class M1 (loss <250 mm³) | EN 13888 |
| Aggregate particle size | 0.1 – 1.2 mm (selectable) | Matte stone finish (Gloss <10 GU) |
| QUV weathering | 1000 h, ΔE <2.0 | UV stable for outdoor use |
| Mix ratio | 10:1 (resin : hardener, by weight) | ±0.5% tolerance at ΔT ±5°C |
Third-Party Certifications:
- French A+ (VOC <30 g/L) — Issued under French VOC regulation (arrêté du 19 avril 2011 relatif à l’étiquetage des produits de construction). Highest grade: ≤ 30 g/L TVOC after 28 days.
- EN 13888 Class M1 (abrasion <250 mm³) — European standard for tile grouts; Class M1 is the highest abrasion-resistance category.
QUV 1000 h ΔE <2.0 is a manufacturer-declared value (internal lab). Third-party QUV report available on request.
Substrate Preparation Requirements
- Joint width: 1 – 5 mm
- Joint depth: ≥ 3 mm
- Substrate moisture content: ≤ 8% (verified by infrared moisture meter)
- Surface must be dust-free (vacuumed) and oil-free (acetone wipe)
Standard Application Procedure
- Mix — Stir 3 minutes at 800 rpm → rest → secondary stir for 1 minute (electric mixer required).
- Apply — Press into joint at 45° angle using 60° hardness rubber float; repeat 2-3 strokes for full compaction.
- Clean — Before surface dry (~40 min @ 25°C), wipe surface with damp sponge in circular motion.
- Cure — Full cure 72 hours @ 25°C / 60% RH. Avoid water contact during cure.
Best Practice & Troubleshooting
- Color consistency: Use same production batch within a single area; avoid direct sunlight on uncured zones.
- Cold-weather application: Pre-warm material to 15-25°C when ambient < 10°C.
- Residential application: Choose mold-resistant variant (kitchens, bathrooms) or stain-resistant variant (living rooms).
- Commercial application: Prioritize abrasion + crack resistance variants (malls, hospitals).
Three Defining Advantages
| Mold-Proof & Waterproof | Eco-Friendly Formula | Convenient Application |
|---|---|---|
| Sealed joint structure prevents biological growth | French A+ certified, <30 g/L VOC | Standard tools, no specialized equipment |
Target Applications
- Premium residential — bathrooms, kitchens, foyers (matte stone finish)
- Hospitality — hotel lobbies, spa floors (1000h UV stable)
- Healthcare — hospitals, clinics (mold-proof, easy-clean)
- Commercial — malls, showrooms (M1 abrasion class)
