Description
When speed matters and preserving the stone's original color is non-negotiable, Tenax Epoxart Kit 4:1 is the professional's choice. Its high reaction speed gets you back to grinding, polishing, or installing faster, while its natural-effect formulation leaves the stone looking exactly as it should — no darkening, no tinting, no color shift. Combined with superb cold reactivity and low yellowing over time, this is the go-to epoxy for high-volume fabrication shops and outdoor stone applications.
Key Features
- Fast cure — high reaction speed minimizes downtime between application and next fabrication steps
- Natural effect — formulated to leave stone color unchanged; no darkening or tinting of the material
- Low yellowing — maintains a clean, neutral appearance over time even with sunlight exposure
- Superb cold reactivity — cures reliably in cold shop or jobsite environments where other epoxies slow down
- Medium viscosity — thicker than water-thin formulas; ideal for fiberglass reinforcement and surface consolidation
- Medium hardness — balanced flexibility to resist re-cracking under load
- Good UV stability — suitable for outdoor stone surfaces and sun-exposed installations
Ideal Applications
- High-speed fiberglass mesh reinforcement of granite and stone slabs
- Stone consolidation where color preservation is critical (light-colored marble, white granite)
- Cold-weather fabrication and outdoor jobsite applications
- High-volume production environments requiring fast turnaround
- Outdoor stone surfaces, pavers, and cladding exposed to sunlight
Kit Contents
- Epoxart A-1006 — 1 kg (Resin, Part A)
- Epoxart B-BB25 — 0.25 kg (Hardener, Part B)
- Total kit weight: 1.25 kg
- Mix ratio: 4 parts resin : 1 part hardener (by weight)
How to Use
- Clean and thoroughly dry the stone surface — remove all dust, oils, and debris.
- Measure by weight: 4 parts resin (Part A) to 1 part hardener (Part B); verify dosing pump ratios daily if using automated equipment.
- Mix thoroughly for several minutes using clean plastic tools; clean tools with acetone or butyl acetate.
- Apply to the prepared surface wearing safety gloves and glasses; work efficiently — fast cure means reduced open time.
- Reseal containers immediately after use; avoid freezing conditions.
Storage & Shelf Life
- Store below 35°C (95°F), away from heat, direct sunlight, humidity, and freezing
- Resin (Part A): 24-month shelf life at 20–25°C
- Hardener (Part B): 12-month shelf life in original sealed containers
Choosing the Right Epoxart Kit
- Epoxart Kit 2:1 — water-thin, water-clear; best for hairline crack repair by capillary action
- Epoxart Kit 3:1 — ultra-clear, slow-cure; best for crack filling where maximum transparency and working time are needed
- Epoxart Kit 4:1 (this product) — fast-cure, natural effect; best for fiberglass reinforcement and color-sensitive stone
Works Well With
- Tenax Epoxart Kit 2:1 — Water-Thin, Water-Clear — use for initial hairline crack consolidation before fiberglass reinforcement
- Tenax Epoxart Kit 3:1 — Ultra-Clear Slow-Cure — when extended working time and maximum clarity are needed
- Tenax Fixtop Knife Grade Epoxy — knife-grade 2-part epoxy for bonding and laminating stone
- Tenax Mixing Cups 12oz (50/Sleeve) — disposable cups for measuring and mixing epoxy components
- Tenax Colored Knife Grade Polyester — for surface chip and void repairs after slab reinforcement
