XR-10 is a high-performance air-dry filler designed to fill fine cracks or bare spots in leather. It can also be used to level out other air-dry fillers. Its thin viscosity formula provides an extremely durable and flexible repair. To achieve a textured finish, XR-10 can be lightly grained using the sizzle grain technique or by warming it to cure it part of the way, then pressing a grain pad into it. Be sure the filler is fully dry before removing the grain pad to avoid any potential lifting. Once fully dry, lightly sand with 600-grit sandpaper and apply a texture using Grain-X spray grain or Texture Paste. Finally, apply color to finish the repair. XR-10 is part of our XR series of extreme repair products, designed to provide superior results for leather repairs.
