★★★★☆ 4.5 out of 5 · 4,962 ratings
Heavy Duty in the quart cartridge for crews that measure a job in sheets, not boards. The same low-solvent, high-strength formula as the 10 oz tube, with nearly three times the bead: wood, treated wood, plywood, OSB, drywall and tile board for framing, paneling and remodeling, waterproof and weatherproof once cured.
Price and stock are shown on the partner store page that opens from the button.
Not recommended for flooring, ceramics, mirrors, granite, marble, plastic, vinyl, underlayment or installing tile board directly to studs.
