What are the Differences Between Interior & Exterior Paint?

Tuesday, May 21, 2013

Though both types of paint may have similar basic elements, understanding the differences between interior paint and exterior paint is crucial for the overall look and safety of your business. All paints contain four major parts: solvents, resins, additives and pigment.

 

Solvent provides moisture and evaporates when paint dries, pigment is simply the color of the paint, resin binds the pigment to wall (epoxy resin or acrylic resin) and additives are chemicals that supply extra benefits depending on the purpose of the paint. The major difference between indoor and outdoor paint is typically the binding resin, but here’s an overall glimpse into their unique features.

 

Interior:

  • Additives provide consistent coverage
  • Easier to remove
  • Usually more resistant to splatters and scuffs
  • Responds well to cleaning
  • Blends in small roller and brush error marks

 

Exterior:

  • Stands up to wear from temperature and moisture
  • Anti-fade UV protection for constant sunlight exposure
  • Additional fungicides and pesticides
  • Mildew prevention
  • Durability
  • Extra pigment and resin
  • Higher VOCs and thus unsafe for indoor use
  • Withstands flexion and contraction due to environmental conditions

 

Painting and organizing your business is no easy task. For challenging interior or exterior paint jobs, you may want to hire a painting company.
