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 .
- 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.
- 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.
- 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.
- 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|
At the time of application, paint shall show no signs of deterioration. Uniform suspension of pigments shall be maintained during application.
You may also refer IS 2395 PART 1&2 and IS 9954 with applicable local laws.
Unless otherwise specified or recommended by the paint manufacturer, the paint may be applied by brush, roller, or spray. Rollers for applying paints and enamels shall be of a type designed for the coating to be applied and the surface to be coated. Wear protective clothing and respirators when applying oil-based paints or using spray equipment with any paints.
Thoroughly work coating materials into joints, crevices, and open spaces. Special attention shall be given to ensure that all edges, corners, crevices, welds, and rivets receive a film thickness equal to that of adjacent painted surfaces.
Each coat of paint shall be applied so dry film shall be of uniform thickness and free from runs, drops, ridges, waves, pinholes or other voids, laps, brush marks, and variations in color, texture, and finish. Hiding shall be complete.
Touch up damaged coatings before applying subsequent coats. Interior areas shall be broom clean and dust free before and during the application of coating material.
- Drying Time: Allow time between coats, as recommended by the coating manufacturer, to permit thorough drying, but not to present top coat adhesion problems. Provide each coat in specified condition to receive next coat.
- Primers, and Intermediate Coats: Do not allow primers or intermediate coats to dry more than 30 days, or longer than recommended by the manufacturer, before applying subsequent coats. Follow manufacturer’s recommendations for surface preparation if primers or intermediate coats are allowed to dry longer than recommended by manufacturers of subsequent coatings. Each coat shall cover the surface of preceding coat or surface completely and there shall be a visually perceptible difference in shades of successive coats.
- Finished Surfaces: Provide finished surfaces free from runs, drops, ridges, waves, laps, brush marks, and variations in colors.
- Film Thickness (DFT): Apply paints, primers, varnishes, enamels, undercoats, and other coatings to a minimum dry film thickness as per manufacturer’s printed recommendations for each coat Coating thickness where specified, refers to the minimum dry film thickness.
