The Uniters edge paint primer/filler is a transparent edge paint primer designed to prepare raw and porous leather edges for a flawless final finish. Applied before Uniters Edge Paint, this primer helps fill grooves and irregularities in the leather, making it especially effective for wide leather edges on items such as bags, belts, and small leather goods. By creating a smooth, even base layer, the edge paint primer improves adhesion and ensures a more refined, rounded edge once the edge paint is applied. The water-based formula is suitable for almost all types of leather and can be applied by hand or by machine, making it ideal for both small workshops and production environments. After drying completely, the primer can be sanded or brushed, allowing you to fine-tune the edge before applying your chosen Uniters Edge Paint color. Thanks to its transparent finish, it can be combined seamlessly with any edge paint shade.
