Ultrafire Crack Repair Kit

SKU: Ultrafire
Sale price$74.95

Ultrafire Crack Repair Kit – Authentic Pizza Ovens
Restore the pristine look of your wood-fired oven with the Ultrafire Crack Repair Kit. Specifically designed for Portuguese brick and clay ovens, this silicone-based, paint-like sealant is the professional standard for maintaining the aesthetic integrity and longevity of your outdoor oven.
Why Use It
  • Cosmetic Restoration: High temperatures naturally cause expansion, leading to thin "spider" cracks on the exterior. This kit fills those gaps to keep your oven looking brand new.
  • Weatherproofing: The silicone-based formula acts as a protective barrier, helping to seal the exterior against moisture, humidity, and the elements.
  • Thermal Flexibility: Unlike rigid cement, this mixture is designed to handle the expansion and contraction cycle of a heating oven without immediately popping back out.

Why Buy It
  • The Authentic Choice: This is the exact proprietary material used by Authentic Pizza Ovens during manufacturing, ensuring a perfect match for their brick oven lines.
  • Ease of Application: No complex masonry skills are required. If you can use a paintbrush, you can repair your oven.
  • Paintable Surface: Once dried, the Ultrafire sealant provides a smooth finish that can be painted over with high-heat masonry paint, allowing you to customize your oven’s color.

Winterizing Your Oven
Winterizing is critical to prevent the "freeze-thaw" cycle from turning small cosmetic cracks into structural issues.
  • Seal Before the First Frost: Use the Ultrafire Kit to seal any existing cracks before temperatures drop. This prevents water from entering the cracks, freezing, and expanding.
  • Moisture Barrier: Applying a fresh layer of Ultrafire acts as a water-repellent skin for the winter months.
  • Breathable Protection: Always use a high-quality, breathable weather cover after the oven has cooled. This prevents snow and rain from sitting directly on the brickwork.

Instructions for Use
  1. Heat the Oven: For the best results, apply the mixture while the oven is hot. This ensures the cracks are at their maximum width during the filling process.
  2. Clean the Surface: Use a steel brush or vacuum to remove any dust, loose debris, or old soot from the cracks.
  3. Initial Application: Using a brush, push the Ultrafire mixture deep into the cracks. If the material sinks as it sets, apply a second layer while the oven is still warm.
  4. Cool Down: Allow the oven to cool completely. Ensure the exterior is dry and free of any grease.
  5. Final Smoothing Coat: Apply a thin, even layer over the repaired areas (or the entire dome) to create a uniform, seamless appearance.
  6. Curing: Let the repair dry for at least 24 hours before your next fire.
Note: This product is intended for external cosmetic repairs only. Do not use it on the internal cooking floor or the interior dome
