# Interior painting

> Walls, ceilings and trim inside the house. Ask with your Sheet attached: homeowners who’ve done it and verified pros answer, and anyone can read it.

## Before you ask

The room size, what’s on the walls now, the sheen you want, and any stains or peeling.

- **Attach your Sheet** so people see your sizes and the math.
- **Your town is enough.** Never your address; check photos for house numbers and plates.
- **Is it safe?** A safety question here goes to pros verified in painting, unless you pick another trade. Only they can call it safe or unsafe.

## Paint a room

14′ × 12′ room, 2 coats: 365 sq ft of wall after the doors and windows, 2.25 gallons of paint in all.

What people get wrong:

- **Skipping primer when it’s needed.** On new drywall or a big color change you get blotchy “flashing” and one or two extra coats.
- **Not boxing the paint.** Two gallons of the “same” color can differ.
- **Wrong nap, overloaded roller.** Drips and texture that doesn’t match.
