Flat, satin, or semi-gloss? Start with the room.

Sheen changes how the paint catches light. Choose it alongside the product, the surface condition, and how the room gets used.

Lower sheen, softer reflection.

Flat and matte finishes reflect less light and can help a wall feel visually quiet. They are often considered for ceilings and living spaces. Lower reflection can also make small surface irregularities less noticeable.

Do not assume all flat paints behave alike. Cleanability comes from the coating formulation as well as the sheen. Compare the actual product information if wiping fingerprints is part of everyday life.

A middle ground for everyday walls.

Eggshell and satin sit in the middle of many finish ranges, but those names are not standardized across product lines. A satin in one line may look different from another satin.

Use a finished sample to judge it under your room lighting. Look straight on and from an angle. A long wall lit from a nearby window may show more reflection—and more preparation flaws—than you expected.

More definition on doors and trim.

Semi-gloss is often chosen when a distinct, reflective trim finish is wanted. Cabinets and doors also need a coating designed for that use; increasing the sheen of ordinary wall paint does not turn it into trim enamel.

Preparation becomes especially visible under reflected light. Fill defects, use an appropriate primer where required, and follow the selected enamel’s application and cure instructions.

The easiest way to choose.

Write down the room, surface, and cleaning needs. Then compare two actual finish options within an appropriate product line. Choose the reflection you like without losing sight of the preparation the surface needs.

Keep this in mindCompare real finish samples. Sheen names and cleaning performance vary by product.
