Painting a room may seem simple at first, but the time it takes to complete the process properly may vary more than most people would expect. The size of the space, wall condition, prep time needed, drying time, and whether you will be doing it yourself or hiring a professional play an important role. Understanding those factors can help you set realistic expectations and prevent surprises once the painting work begins.
Typical Timeframes
For a standard 12’ x 12’ bedroom with 8 ft. ceilings:
- Professional: 6 to 8 hours
- DIY: 10 to 16 hours
These estimates include:
- Prep work: 2 to 3 hours
- Cutting in(borders and edges): 1 to 2 hours
- Rolling:2 to 4 hours
- Drying between coats: 2 to 4 hours
- Cleanup: 1 to 2 hours
Note: Larger rooms, higher ceilings, or complex room layouts will increase the total time. For instance, a full interior house painting project may typically take about 3 to 7 days. Professionals with a crew can complete the work faster.
Factors that Determine How Long A Painting Job Takes
Room Size
The biggest factor to consider when it comes to how long a painting job takes is square footage and ceiling height. A smaller bedroom will be much quicker than a wide open concept living room.
Estimated Timelines:
- Small room: 4 to 8 hours (Pro), 8 to 10 hours (DIY)
- Standard bedroom: 6 to 10 hours (Pro), 10 to 16 hours (DIY)
- Large living room: 10 to 20+ hours (depending on height, layout, and condition of the walls)
Prep Work: An Underestimated Step
Prep work often takes as long as the actual painting. Skipping this step may lead to uneven finishes and premature paint failure. Typical prep tasks include:
- Moving and covering furniture
- Cleaning walls
- Taping trim, windows, doors, outlets, etc.
- Repairing holes and cracks
- Patching and sanding drywall
- Priming (if needed)
Moreover, older homes, textured surfaces, or dark existing paint colors can extend prep time because they require additional work.
Painting Process
Cutting In
This painting work requires precision along edges where rollers may not be able to reach.
- DIY: 1.5 hours to 3 hours
- Pro: 45 mins to 1.5 hours
Rolling
This process will cover most of the wall surface. However, to get full coverage, you may still require multiple coats. Most rooms will require two coats for the best results.
- DIY: 2 to 4 hours per coat
- Pro: 1 to 2 hours per coat
Drying Time
Drying time is essential, especially when painting walls. Skipping this process will cause streaks, peeling, and overall poor results.
Typical Drying Time Between Coats
- Latex paint: 2 to 4 hours between coats
- Oil based paint: 6 to 24 hours between coats
Additionally, if the wall needs a primer and multiple coats, this will also add to the drying time
Other Factors That Add Time
Some features may require additional detail work or additional paint. For instance:
- Textured walls
- Custom patterns and designs
- Repairs to dents or uneven surfaces
