Drywall Trowl

The drywall trowel evolved from ancient plastering tools, initially simple wood/stone blades, becoming specialized metal versions for lath & plaster systems in the 19th century, then adapted by painters into larger knives, and finally refined with stainless steel and ergonomic designs for modern drywall finishing, becoming a distinct tool as drywall replaced plaster after WWII for faster construction. Key developments include the rise of companies like Marshalltown, incorporating better materials and automation for efficiency in the booming post-war industry, with the modern trowel offering flexibility and control for smooth joint compound application. Early Origins (Ancient Times - 19th Century) Ancient Roots: Simple trowels of wood, stone, or bone were used for applying plaster in ancient Egypt, Greece, and Rome for everything from pyramids to temples, a tradition continuing through the Middle Ages. Lath & Plaster Era: Before drywall, skilled plasterers used basic trowels and "hawks" (boards holding plaster) to apply multiple coats over wood lath, a labor-intensive process. Transition to Drywall (Late 19th - Mid 20th Century) Proto-Drywall Tools: By the 1890s, as alternatives to lath & plaster emerged, plasterers adapted their trowels for new systems, while painters brought their putty knives, making them larger for drywall taping. Drywall's Rise: Invented in 1916 (USG Corp.), drywall became dominant post-WWII due to wartime labor shortages, offering faster, less skilled construction. Dedicated Tools Emerge: Companies like Marshalltown Trowel Company (founded 1905) specialized, and by 1946, Mel Masterson of Wal-Board Tools designed patented drywall-specific items, creating tools for the new industry. Modern Era (Mid-20th Century - Present) Material & Design Advances: The shift from basic metal to stainless steel blades and more flexible designs improved control and precision. Automation & Specialization: Power tools and automated taping tools streamlined installation, while trowels evolved for specific mudding and finishing tasks, enhancing both speed and quality. Key Innovations: Modern trowels, often made of flexible stainless steel with ergonomic handles, are designed to work the joint compound smoothly, a significant improvement over older, stiffer tools.
