Paint coat quick guide

When painting an interior wall, several factors can influence the number of coats needed.

What increases the number of coats

  • Painting on rough or textured surfaces like fresh drywall or plasterboard
  • Using darker colours or painting over darker colours
  • Matt finish usually requires more than gloss and silk to get an even finish

Tips for reducing the number of coats

  • Rough or textured surfaces Increasing the amount of paint can compensate for extra absorption when painting on
  • Stains or watermarks Use a primer or apply an additional coat to ensure proper coverage when painting over
  • Darker colours: Purchase slightly more paint than calculated to account for potential additional coats
  • Matt finish: Consider using a primer or applying an extra coat for even coverage.
