Your Step-By-Step Guide to Painting the Perfect Wall

Painting a room is a manageable task that even renovation novices can tackle in one weekend unlike retiling your kitchen floor. But before you grab your brush and dive right in, it’s important to master a few basics—like how to prep the walls and the tools you’ll need to avoid any painting mishaps.

Necessary Materials

Like any home project, there are a few things you’ll need in your arsenal in order to get the job done.

• Spackle (if you need to fill in holes)
• Spackle knife
• Sandpaper
• Tack cloth
• Primer
• Painter’s Tape
• Drop cloths
• Paint brushes
• Shedless Rollers
• Paint tray
• Paint

Prepare Walls for Painting

If your walls are in need of a fresh coat of paint, it’s evident that they haven’t been touched up in a while. Fill in holes and clean up stains or marks before adding more paint to these imperfections.

Check for Imperfections

Inspect your walls for cracks, holes or stains before you open a paint can. “First, look at the wall and see if there are repairs that need to be made,” says Chris Richter, senior paint merchant at The Home Depot. “Fill holes from things like pictures and peel away areas of chipping paint.”

Sand Patched Areas

Sand down the areas if you found any flaws that needed to be repaired prior to painting. If you don’t, your paint job may look uneven from spackling left behind. After sanding, use a tack cloth to clean up any dust from sanding. “You can spot prime those patched or repaired areas, but a primer on its own is generally unnecessary,” says Richter. He adds that priming an entire wall is only necessary if it’s in bad shape or stained.

Clean Wall Marks

If your wall has a few marks, Richter asks to use a rag and a household cleaner to wipe the area. For tough grease stains, he suggests using a trisodium phosphate cleaner—a non-toxic cleaner which is a good choice if you need to lightly wipe down the wall and remove any dirt or oils.

How to Paint a Wall

1. Cover Areas You Don’t Want Painted

Use painter’s tape to protect baseboards and other areas like moldings, door and window casings, light fixtures, and switch plates once your wall is in good shape. Also cover nearby valuables. Move furniture out of the room, or place in a centralized location in the room, and cover with plastic or a canvas tarp. Protect the floors with a drop cloth.

2. Pour Your Paint

Now it’s time to open up your paint can and pour it into a tray. “The ramp of the tray helps distribute paint evenly on the roller,” says Richter. “And trays can also be a good way to work faster if you have more than one person painting.” For bigger jobs he recommends using a roller screen combined with the 5-gallon bucket for an even more efficient system.

3. Paint Along the Trim

Known by professionals as “cutting in” Richter recommends using a paint brush to paint the top and bottom areas of your wall along the trim. When painting, move the brush in a smooth, side-to-side motion. According to Richter, you should paint the trim before moving to the ceiling or middle sections of your walls. However, he notes that you should only work in small, 4-foot sections of the trim at a time.

4. Paint the Ceiling

If you’re painting an entire room including the ceiling, Richter recommends tackling the ceiling before the walls.

5. Paint the Walls

Move onto the walls once you’re done with the ceiling. Dip you roller in paint and move your roller in a vertical motion, going from the top of your walls to the bottom.

6. Leave a Wet Edge

When painting the ceiling and walls, you want to keep a “wet edge.” This means that the “cut in” sections of paint need to stay wet and not dry before you go back in vertically with your roller. This is why it’s best to work in small sections.

Drying Time

When you’re finished painting, Richter recommends not touching the walls for at least two hours. Instead, focus your energy on preserving your brushes and any remaining paint. “Rinse your brushes and rollers with warm water and maybe a little bit of mild soap,” he says. “Most paints are water-based so they clean off easily. Keep rinsing until all the paint is gone and then it’s ready to dry and store.” For the cans of paint, just hammer the lid back on and store in a cool, dry place.
