Joint Compound Vs. Plaster: Differences And Applications

Joint compound, used for smoothing drywall seams and walls, comes in premixed and powder forms, while plaster, a more durable material, is available as plaster of Paris and gypsum plaster. Joint compound is applied in multiple coats to reinforce and conceal imperfections, while plaster is used for more significant repairs, leveling surfaces, and creating decorative finishes. Both require specialized tools, including drywall knives for joint compound and trowels and hawks for plaster.

Joint compounds (aka drywall mud) are the unsung heroes of any drywall project. They fill and smooth out the gaps between drywall panels, creating a seamless surface ready for paint or wallpaper. There are two main types of joint compounds:

  • Hot Mud (Setting-Type): Dries hard and fast, making it ideal for larger gaps and repairs.
  • Cold Mud (Pre-Mixed): Easy to use and perfect for smaller jobs like filling nail holes and smoothing out imperfections.

Plaster of Paris and Gypsum Plaster: The Dynamic Duo

Plaster of Paris and gypsum plaster are used for different purposes, but they both have one thing in common: they’re made from gypsum, a naturally occurring mineral.

  • Plaster of Paris: Quick-setting and strong, making it perfect for molds and casts.
  • Gypsum Plaster: Slower-setting and more versatile, making it ideal for patching walls, ceilings, and even creating decorative moldings.

  • Plastering:
    • Skimming: Applying a thin layer of plaster to smooth imperfections
