ZÜNDER is a drywall finishing tool designed to make the process faster and easier than ever before. It simultaneously applies compound and joint tape for sealing seams on flat joints, inside corners, and square connections. Its unique dual-sided applicator switches in seconds, maintaining full control over compound application with a precision regulator. The tool features a large 0.58-gallon capacity and accommodates joint tape rolls up to 500 feet long. Constructed from polycarbonate, it offers impressive durability and impact resistance. Two adjustable soft-grip handles provide comfort for both right- and left-handed users, while the one-latch design allows quick access for loading and cleaning. Compatible with paper or fiber tape such as FibaFuse.
