Eco-Flo Gum Tragacanth is a water based, low V.O.C., natural gum based edge slicking and burnishing compound for use on natural or colored veg-tanned leather. Produces a professional looking, smooth, shiny, burnished edge. Directions for use: Shake well before each use. For best results, round off edge of leather with an edge beveler prior to application. Apply a thin coat of Gum Tragacanth to beveled edge of leather with a wool dauber, cloth or slightly damp sponge. Rub edge very briskly with an edge slicker, bone folder or piece of canvas. As the Gum Tragacanth dries and heats up due to friction caused by rubbing, treated edge will darken and shine. Repeat until desired burnish is achieved. Use caution when applying Gum Tragacanth on leather that is to be stained, antiqued or dyed, as it may resist or block penetration of some color.
