Renia Cork Filler

Renia Cork Filler – 8oz and 16oz.

Renia Cork Filler is a professional-grade filling compound designed specifically for shoemakers, leatherworkers, and repair artisans who require a lightweight, reliable solution for filling cavities in footwear and leather goods. Formulated with high-quality cork granules and a durable binder, this product creates a stable base that adds structure and comfort to layered builds.

Whether you're working on Goodyear welted shoes, orthopedic builds, or bag and case construction, Renia Cork Filler helps bridge voids, reduce weight, and create a smooth surface for final assembly. Once cured, it can be sanded and bonded over—ideal for both new builds and repair work.
