Leather sealer
A liquid topcoat, such as Resolene, applied after dyeing to protect color and add a light sheen or water resistance.
A leather sealer is a liquid finish, often an acrylic resin product like Resolene, brushed, sponged, or sprayed over dyed or painted leather as a final protective topcoat. It is usually the last step in finishing a piece, applied once dye or paint has fully dried.
Sealing locks dye pigment in place so it rubs off less onto clothing or hands, and it adds a degree of water resistance along with a sheen that ranges from a matte, natural look to a glossy finish depending on the product and how many coats are applied. Unsealed dyed leather, especially darker colors, is far more prone to transferring color with handling.
Thin, even coats dry more reliably clear than one heavy coat, which can pool, streak, or dry cloudy in spots. Testing sheen and coverage on a scrap piece first is worth it since sealers vary in finish and some interact differently with different dye types. A common mistake is sealing over leather that has not fully dried after dyeing or conditioning, which traps moisture and can cause the topcoat to haze or peel later.
