Cosflex Prime and Seal is a non-toxic, water-based brush-on primer and semi-gloss top coat designed for cosplay, prop-making, and crafting. This versatile formula applies smoothly, dries clear with minimal tackiness, and maintains flexibility even on curved or deformed surfaces. Thicker than typical glue-based primers, it provides excellent coverage with fewer layers needed. Ideal for use on EVA foam, thermoplastics, fabrics, wig fibers, and more, Cosflex creates a strong yet flexible bond. Easy to use and clean, it features a low-odor, water-soluble formula that rinses off with water—no harsh chemicals required. For extra protection, simply top coat with a clear acrylic sealant spray.
