Joint filler, also known as caulking agent or crack filler, is a powdery building material mainly composed of white cement, inorganic pigments, polymers, and antibacterial agents. It is commonly used indoors to join drywall or for repairs, and is more flexible than gypsum or cement-based joint compounds. The addition of cellulose ether provides it with good edge adhesion, low shrinkage, and high abrasion resistance, protecting the base material from damage and preventing penetration throughout the building. Ready-mixed joint fillers are specifically designed for inlay tape and are a reliable choice for efficient and durable building repairs.
