How to Paint a Room in One Day: And Why Bananas Might Be the Secret to a Perfect Finish

Painting a room in a single day might seem like a daunting task, but with the right preparation, tools, and mindset, it’s entirely achievable. Whether you’re looking to refresh your living space or preparing your home for sale, a fresh coat of paint can work wonders. In this guide, we’ll explore the step-by-step process of painting a room in one day, while also diving into some unconventional tips—like why bananas might just be the secret to a perfect finish. Let’s get started!


Step 1: Plan and Prepare

Choose Your Paint Color

The first step in painting a room is selecting the right color. Consider the mood you want to create—calm and serene, vibrant and energetic, or cozy and warm. Don’t forget to test paint samples on your walls to see how they look in different lighting conditions.

Gather Your Supplies

To paint a room efficiently, you’ll need the following:

  • Paint (primer and topcoat)
  • Paint rollers, trays, and extension poles
  • Paintbrushes (angled and straight)
  • Drop cloths or plastic sheeting
  • Painter’s tape
  • Sandpaper or a sanding block
  • Spackle and a putty knife
  • Cleaning supplies (sponges, soap, and water)
  • A ladder (if needed)

Clear the Room

Remove as much furniture as possible. For larger pieces, move them to the center of the room and cover them with drop cloths. Take down curtains, wall art, and outlet covers. This will give you a clear workspace and prevent accidental paint splatters.


Step 2: Repair and Prep the Walls

Patch Holes and Cracks

Inspect your walls for any holes, cracks, or imperfections. Use spackle to fill them in, and once dry, sand the area smooth. This step ensures a flawless finish.

Clean the Walls

Dust, dirt, and grease can affect how well the paint adheres to the walls. Wipe down the walls with a damp sponge and mild soap. Allow the walls to dry completely before moving on.

Apply Painter’s Tape

Use painter’s tape to protect trim, baseboards, windows, and door frames. Take your time with this step to ensure clean lines and avoid paint bleed.


Step 3: Prime the Walls

Why Primer Matters

Primer creates a uniform surface for the paint to adhere to, especially if you’re covering dark colors or stains. It also helps the topcoat appear more vibrant and last longer.

How to Apply Primer

Use a roller for large areas and a brush for edges and corners. Work in sections, starting from the top of the wall and moving downward. Allow the primer to dry according to the manufacturer’s instructions—usually 1-2 hours.


Step 4: Paint the Walls

Cut In the Edges

Before using the roller, use an angled brush to “cut in” around the edges of the room, including corners, ceilings, and trim. This creates a clean border and makes rolling easier.

Roll the Walls

Pour paint into a roller tray and load your roller evenly. Start at the top of the wall and work in small sections, using a “W” or “M” pattern to distribute the paint. Roll over the area in straight lines to smooth out the paint. Repeat until the entire wall is covered.

Apply a Second Coat

Once the first coat is dry (check the paint can for drying times), apply a second coat for a more even and durable finish. Don’t forget to remove the painter’s tape while the paint is still slightly wet to avoid peeling.


Step 5: Clean Up and Reassemble

Clean Your Tools

Rinse brushes and rollers thoroughly with water (for latex paint) or the appropriate solvent (for oil-based paint). Proper cleaning ensures your tools last longer.

Reassemble the Room

Once the paint is completely dry, move the furniture back into place, rehang curtains and wall art, and replace outlet covers. Step back and admire your work!


Bonus Tips for a Perfect Finish

The Banana Trick

Here’s where things get unconventional. Some DIY enthusiasts swear by using a banana to clean up small paint smudges on trim or glass. The natural oils in the banana peel can help lift dried paint without damaging the surface. Give it a try—it might just work!

Work in Natural Light

Natural light helps you spot missed spots or uneven coverage. If possible, schedule your painting project during daylight hours.

Stay Organized

Keep your supplies within reach and work systematically. This minimizes downtime and keeps the project on track.

Don’t Rush

While the goal is to finish in one day, rushing can lead to mistakes. Take your time, especially during prep and cutting-in stages.


Frequently Asked Questions

Can I paint over wallpaper?

It’s possible, but not recommended. Paint may not adhere well to wallpaper, and seams or patterns could show through. It’s best to remove the wallpaper first.

How long should I wait between coats?

Drying times vary by paint type and environmental conditions. Generally, wait 2-4 hours for latex paint and 24 hours for oil-based paint.

Do I need to sand the walls before painting?

Sanding isn’t always necessary, but it helps smooth out imperfections and improves paint adhesion. Lightly sanding between coats can also create a smoother finish.

What’s the best way to store leftover paint?

Store paint in a cool, dry place with the lid tightly sealed. Label the can with the room and date for future reference.

Can I paint over a dark color with a lighter one?

Yes, but you may need multiple coats or a tinted primer to ensure full coverage.


Painting a room in one day is a rewarding challenge that can transform your space. With careful planning, the right tools, and a little creativity (bananas included), you’ll have a freshly painted room to enjoy in no time. Happy painting!
