DAP Alex Plus Spackling is a professional-strength, ready-to-use spackling compound designed to fill holes, cracks, dents, and surface imperfections in drywall, plaster, wood, brick, metal, and stone. Its one-coat formula resists sinking and shrinking while creating durable repairs that resist cracking, crumbling, and flaking. It sands easily to a smooth, paint-ready finish, and its superior paintability helps minimize flashing under flat and low-sheen paints. Suitable for interior and exterior use, it offers convenient application and easy water cleanup while wet.
