Deep Dive: Historical Background 🕰️
Origin of “Lath”
The word lath comes from Old English and Germanic roots referring to thin strips or boards. Historically, laths were essential in home construction before drywall became common.
Builders nailed wooden laths horizontally across wall studs. Wet plaster was then spread over them to create durable walls.
Even today, many historic homes still contain original lath-and-plaster walls.
Origin of “Lathe”
The word lathe has ancient roots connected to shaping and turning materials. Early lathes date back thousands of years.
