Description
This 4-1/2-Gallon USG Sheetrock® Midweight™ Joint Compound is a lighter-weight finishing compound designed for faster, more user-friendly drywall work. You’ll appreciate that it weighs up to 15 percent less than conventional-weight compounds while still offering low shrinkage, excellent slip and good crack resistance, so taping, bedding and finishing are smoother and truer. It provides more open time and extended wet-edge life, which helps you work back into seams without rolling or tearing previously laid compound, even under fast-drying conditions. The formula delivers strong bonding and maintains performance in humid job environments. Off-white in color and composed of attapulgite, limestone, mica and perlite, this compound meets ASTM C475 and covers roughly 1,000 sq ft, making it suitable for most residential drywall repairs and finishing runs.
