Joint compound is essential for drywall finishing, patching, and surface smoothing, creating seamless, professional-quality walls and ceilings. Used to fill seams, cover screw holes, and repair cracks, it ensures a smooth, paint-ready surface. Lightweight joint compound dries quickly for easy sanding and finishing, while all-purpose joint compound provides excellent adhesion and durability for multiple drywall applications. Topping compound enhances final coats for a polished appearance, and setting-type joint compound offers faster drying and shrinkage resistance for large repairs and high-humidity areas. Whether used for new drywall installations, patching dents, or leveling surfaces, joint compound ensures strong, durable, and smooth finishes for residential and commercial construction.
