Plaster vs. Drywall: What’s the Difference?

Plaster and drywall are two common materials used to finish interior walls. While both serve the same purpose, they differ in terms of installation, durability, aesthetics, and cost. Here’s a clear breakdown to help you decide which is best for your project.

Plaster vs drywall

FeaturePlasterDrywall
Material CompositionLime or gypsum + sand + water (applied in layers)Gypsum core sandwiched between paper sheets
InstallationHand-applied over lath or mesh; labor-intensivePre-made sheets screwed to studs; faster install
FinishSmooth, seamless, or textured; flexible designFlat or textured; uniform appearance
DurabilityHarder surface, more crack-proneSofter surface, easier to dent or damage
SoundproofingBetter due to wall thicknessModerate
InsulationSlightly better thermal and acoustic insulationGood, especially with insulation behind
Fire ResistanceHigh (burns slower)Standard fire resistance
Repair DifficultyHarder; often requires a professionalEasier DIY repair with patch kits
Cost (Installed)$2 – $10 per sq. ft.$1 – $3 per sq. ft.
DIY FriendlyNot recommendedYes
Best UseHistoric restorations, high-end interiorsStandard modern construction

Plaster is applied wet over wood lath or metal mesh in multiple coats. It requires more time, skill, and curing.

Drywall consists of gypsum boards screwed into studs, then finished with joint compound over seams.

Plaster

Pros:

  • Superior soundproofing and fire resistance
  • High-end finish with custom textures and curves
  • Long-lasting when installed correctly
Cons:

  • Expensive to install
  • Time-consuming and labor-intensive
  • Can crack with home movement

Drywall

Pros:

  • Affordable and widely available
  • Easy to install and repair
  • Compatible with modern construction standards
Cons:

  • Less durable than plaster
  • Visible seams if not finished well
  • Limited design flexibility

Which One Should You Choose?

Choose plaster if you want a premium, traditional finish or are restoring a historic home.

Choose drywall for cost-efficiency, faster installation, and easier maintenance in modern builds.
