Flexbond by Rosco - Prime and Seal - Primer and Sealant for Eva Foam, Plastazote, and Worbla - White - 16oz and 32oz Options Available (White, 16oz (Twin Pack))

Flexbond by Rosco is a strong, pliable glue-based primer and sealant. It’s ideal for use with EVA foam, thermoplastics, fabric, Fosshape, paper, wig fibers, and more. It dries to a clear, semi-gloss finish and remains flexible and durable—without the tackiness often found in similar products—even as the coated materials bend or deform. Flexbond is non-toxic, has a minimal scent, and is water-soluble, making it easy to clean up spills or project residue. It brushes on smoothly and works well as both a paint primer and a semi-gloss topcoat. However, we recommend applying a clear acrylic sealant spray over your Flexbond layer to provide additional protection for your project.
