💡 Why Choose This Solution?
Tenax T8 represents the professional standard for critical areas in sink and kitchen countertop production. The filler creates an inseparable bond between the reinforcement and the material (stone/gres). It eliminates the risk of cracking in weakened sections during handling and ensures long-term rigidity of the entire piece with minimal shrinkage.
🛠️ Professional TIP from practice: When embedding reinforcements, ensure the groove is 2–3 mm wider than the reinforcement itself. The T8 filler must completely "submerge" the reinforcement on all sides to prevent point stress. Mix with the activator at a ratio of 1–3% (never more than 3%, otherwise the filler becomes brittle).
🔍 Expert Perspective: T8 is our standard for manufacturing bonded sinks, where we primarily use it for embedding metal reinforcements. Without this structural reinforcement, the material is highly susceptible to cracking in critical areas. With T8, we ensure the metal reinforcement integrates perfectly with the material, allowing the sink to safely withstand both transport and installation.
✅ Main Benefits
- Extreme structural adhesion to ceramics and granite
- High mechanical resistance and minimal shrinkage
- Lightning-fast strength gain (workable within 30 min)
⚠️ What to Watch Out For
- Characteristic odor (work in a ventilated area)
- Not intended for aesthetic visible joints
- Strict necessity of precise activator dosage (max 3%)
Practical Questions (FAQ)
Can T8 be used on vertical surfaces?
Yes, the filler has thixotropic properties, meaning it does not run out of milled grooves and holds its shape even in a vertical position.
Which reinforcement is recommended for use?
For structural elements, the best results are achieved with metal or fiberglass rods, which the T8 filler perfectly encapsulates.
Can I sand the slab immediately after curing?
Yes, T8 filler becomes very hard after approx. 30 minutes and can be sanded flush with the slab surface without clogging the abrasives.
