How to Choose Paint

There’s a basic rule to be followed when choosing paint type & sheens: The higher the sheen, the higher the shine — and the higher the shine, the more durable it will be. Gloss, Semi-Gloss, Satin, Matte and Flat are the most popular paint sheens (also called paint finishes) for your home .

High Gloss

  • The glossier the finish, the greater the durability.
  • Higher the gloss, a more washable and easy to clean.
  • High-gloss paint is hard and light-reflecting.
  • Application area: Cabinets, trim, and doors.

Semi-Gloss

  • The durable and easy to clean.
  • Good for rooms where moisture, drips, and grease stains challenge walls. Also great for trim work that takes a lot of abuse.
  • Application area: kitchens, bathrooms, trim, chair rails.

Satin

  • Durability is medium.
  • Satin is used in the same way as the gloss but is slightly less shiny and is increasingly popular, especially for interior woodwork and wall.
  • Application area: Family rooms, hallways, kids’ bedrooms.

Eggshell

  • Between satin and flat on the shine (and durability) scale is eggshell, so named because it’s essentially a flat (no-shine) finish with little lusters, like a chicken’s egg.
  • It is commonly used on interior surfaces as an alternative to semi-gloss, although some manufacturers will specify that the paint may be used on exterior surfaces.
  • Application area: dining rooms, living rooms.

Flat or Matte

  • Is the least reflective sheen available.
  • Flat is normally used for walls and ceilings.
  • Offers great depth of color.
  • Durability is medium to low.
  • Application Area: Bedrooms and other interior rooms.

MPI Gloss Levels-

MPI system of defining gloss: Seven (7) gloss levels (G1 to G7) are generically defined under the Evaluation sections of the MPI Manuals. Traditionally, Flat refers to G1/G2, Eggshell refers to G3, Semi-gloss refers to G5, and Gloss refers to G6.

Gloss levels are defined by MPI as follows:

Gloss Level  Description      Units at 60 degrees    Units at 85 degrees
G1 Matte or Flat 0 to 5 10 max
G2 Velvet 0 to 10 10 to 35
G3 Eggshell 10 to 25 10 to 35
G4 Satin 20 to 35 35 min
G5 Semi-Gloss 35 to 70
G6 Gloss 70 to 85
G7 High Gloss
