Painting Time by Room Size
| Room | Prep | Painting | Total (2 coats) |
|---|---|---|---|
| Small bathroom 5×8 | 30 min | 1.5 hrs | ~2–3 hours |
| Small bedroom 10×10 | 45 min | 2 hrs | ~3–4 hours |
| Average bedroom 12×14 | 1 hour | 3 hrs | ~4–6 hours |
| Living room 15×20 | 1.5 hrs | 4 hrs | ~6–8 hours |
| Large open plan 20×30 | 2 hrs | 6 hrs | ~8–12 hours |
How Long Does Each Stage Take?
Prep (20–30% of total time). Moving furniture, laying drop cloths, filling holes, sanding, and taping edges. Prep is the most time-consuming part — but the most important. Rushing prep means imperfect results that are visible for years.
First coat (30–40% of total time). Cutting in with a brush around all edges and corners, then rolling the main wall surfaces. Allow 2–4 hours before applying the second coat.
Drying time between coats. Latex paint needs 2–4 hours between coats. This is dead time — use it to clean brushes, eat lunch, or prep another room.
Second coat (similar to first coat). Goes faster than the first coat as edges are already cut in cleanly.
Cleanup (15–20 minutes). Remove tape while paint is still slightly tacky to avoid peeling. Clean brushes and rollers. Replace furniture after 24 hours.
How to Paint a Room Faster
Use a quality roller. A good 9-inch roller with a 3/8 inch nap applies paint twice as fast as a cheap one and gives better coverage in fewer passes.
Cut in all edges first. Cut in the entire room before you start rolling. This lets you roll quickly without worrying about edges and creates a consistent wet edge.
Work wall to wall. Complete each wall fully before moving to the next. Do not roll halfway across a wall and leave it — this creates lap marks.
Paint the ceiling first. If painting both ceiling and walls, do the ceiling before the walls — any drips are covered when you roll the walls.
