It has the same gypsum core that you’ll find on standard drywall all over homes, but it comes with a thicker coating of paper that’s protected by wax for water resistance.
Why are American houses made of drywall?
The primary advantage of drywall over plaster is labor savings — you can install drywall in considerably less time than plaster, and it makes for a very smooth wall. In addition, if you use 5/8″ thickness or greater, the walls you build are fire resistant — even over wood studs.
Why would you plaster over drywall?
Veneer plaster is much harder than a regular drywall surface, making it less likely to get unsightly dents and scratches. On a drywall surface, paint can dry differently on the paper surface than on the joint compound base at drywall seams.
