Do You Paint Trim or Walls First? The Case for Each Approach
Painters generally follow two common methods:
Painting trim first, then walls
Painting walls first, then trim
Each method has its advantages, and the best choice depends on factors like drying time, masking difficulty, and your painting skill level.
Method 1: Painting Trim First, Then Walls
Many professional painters prefer to paint the trim first. This includes baseboards, door casings, crown molding, and window trim.
Pros of Painting Trim First
Easier to Tape Off the Trim: Since trim pieces are straight and narrow, it’s easier to apply painter’s tape to protect them when painting the walls later.
Less Dripping on Walls: If you paint the walls first and then do the trim, there’s a risk of dripping trim paint onto the freshly painted walls.
Better Cutting-In Control: It’s easier to cut in neatly along the trim when painting the walls rather than trying to cut in perfectly around wall paint when doing the trim last.
Cons of Painting Trim First
Requires Extra Taping: Once the trim dries, you’ll need to tape it off to protect it when painting the walls.
More Risk of Smudging: If you’re not careful, painting the walls later might lead to accidental scuffing or marks on the trim.
Method 2: Painting Walls First, Then Trim
Some people prefer to paint the walls first and tackle the trim afterward.
Pros of Painting Walls First
Easier and Faster Coverage: Rolling out the walls first allows for quick, broad strokes without worrying about staying inside trim lines.
Less Tape Needed Initially: You won’t need to tape off the walls as you would with the trim-first method.
Good for Sprayers or Large Wall Areas: If you’re using a paint sprayer or have a large wall area, it's more efficient to do the walls first.
Cons of Painting Walls First
Harder to Cut In Around Trim: When painting trim after the walls, you’ll need a steady hand or more taping to avoid getting trim paint the walls.
Potential for Drips on Walls: If you’re painting trim last, it can be difficult to avoid getting white or semi-gloss trim paint on the finished walls.
Which Method Is Best?
The best choice depends on your situation. Here are of our recommendations based on different scenarios:
For Beginners: Painting trim first is usually easier, as it allows for more controlled cutting in.
For Speed: Painting walls first allows you to roll quickly without worrying about trim edges.
For Professional Results: Trim-first provides a cleaner final look because walls can be cut in more precisely.
If Using a Sprayer: Paint the walls first, then do the trim carefully by hand.
How to Paint the Walls of Your Home
Painting your home’s walls is one of the most cost-effective ways to rejuvenate and update your living space. With the right tools and preparation, you can achieve a professional-looking result. Here is our step-by-step guide to help you paint your walls, including instructions on painting the trim first and then the walls.
Step 1: Gather Your Supplies
Before you start, ensure you have the necessary materials:
Paint (latex or oil-based)
Primer (if needed)
Paint rollers and trays
Angled paint brushes
Painter’s tape
Drop cloths or plastic sheeting
Sandpaper (120- to 150- grit)
Spackle and putty knife
Ladder or step stool
Step 2: Prepare the Room
Preparation is crucial for a smooth finish.
Clear the area—Move furniture away from the walls and cover it with plastic sheets
Protect the floors—Lay down drop cloths or plastic sheeting.
Remove outlet covers and switch plates—This prevents paint from getting on them.
Clean the walls—Usea damp cloth or mild detergent to remove dust and grease.
Fill holes and cracks—Applyspackle to any imperfections and sand them smooth once dry.
Tape off edges—Use painter’s tape to mask baseboards, windows, and door trim.
Step 3: Painting the Trim First
Many professionals recommend painting the trim before the walls.
Use an angled brush—Dip your brush into the paint and tap off excess.
Start with the baseboards—Paint in long, smooth strokes.
Paint the door and window trim—Follow the wood grain for a natural finish.
Let the trim dry—This usually takes 24 hours.
Apply a second coat—If needed, apply another coat for an even finish.
Remove the tape carefully—peel it off slowly at a 45-degree angle to avoid peeling paint.
Step 4: Painting the Walls
Once the trim is dry, you can move onto the walls.
Prime the walls (if needed)---If you’re painting over a dark color or new drywall, apply a primer first.
Cut in the edges— Use an angled brus to paint along the edges where the wall meets the trim and ceiling.
Use a roller for large areas—Dip the roller in the paint tray, remove excess paint, and roll in a “W” or “M” pattern for even coverage.
Work in sections—Paint one wall at a time to maintain a wet edge and prevent streaks.
Let the first coat dry—wait at least 2-4 hours before applying a second coat.
Apply the second coat—Repeat the process for a smooth, even finish.
Step 5: Finishing Touches
Remove painter’s tape—Do this while the paint is still slightly wet to avoid peeling.
Touch up any mistakes—Use a small brush to correct any drips or uneven areas.
Reinstall outlet covers—Once the paint is dry, put everything back in place.
Clean up—Wash brushes and rollers, and dispose of used drop cloths properly.
By following these steps, you can achieve a beautiful, long-lasting paint job in your home.
Best Paint Types for Trim and Walls
Choosing the right type of paint can make a big difference in durability and appearance.
Trim Paint: Use a semi-gloss or high-gloss finish for easy cleaning and durability.
Wall Paint: Matte, eggshell, or satin finishes work best for most interior walls.
