Painting: Complete Guide

Overview

Painting is one of the highest-return DIY tasks. Professional labor costs $2-$4 per square foot, while materials cost only $0.30-$0.60 per square foot. Owner-builders who paint themselves save $4,000-$8,000 while achieving professional results with patience and proper technique.

I always recommend owner-builders paint their own homes. It's tedious but straightforward, requires minimal tools, and dramatically impacts the final appearance while saving significant money.

When This Phase Happens

Painting happens after trim installation but often in two stages.

First coat (before trim installed):

Final coats (after trim):

My recommendation: DIY interior painting, consider hiring exterior (height and safety concerns). Interior painting is straightforward and saves massive money. Exterior involves heights, weatherproofing, and specialized equipment.

Most owner-builders successfully paint their interiors, saving $4,000-$6,000 in labor costs.

Step-by-Step Process

Days 1-2: Preparation (Most Important Step!)

The saying is true: "90% prep, 10% paint."

Drywall prep:

  1. Fill all nail holes with spackle
  2. Sand any ridges or rough spots (120-grit)
  3. Caulk gaps between trim and walls (paintable caulk)
  4. Caulk gaps at corners and joints
  5. Wipe down all surfaces (remove dust)
  6. Vacuum thoroughly

Protecting:

  1. Remove outlet and switch covers
  2. Cover floors with drop cloths
  3. Tape off areas you don't want painted:
    • Windows (tape glass edges)
    • Hardware
    • Floors if installed
  4. Cover light fixtures with plastic bags
💡Pro Tip

Quality prep work makes the difference between amateur and professional results. Don't skip this step. Time spent prepping saves time painting and produces better results.

Days 3-4: Priming

Why primer is essential:

Primer application:

  1. Start with ceiling
  2. Cut in edges with brush (3-4" wide band)
  3. Roll main areas with 9" roller
  4. Use extension pole (saves ladder time)
  5. Apply even coat (not too thick)
  6. Let dry per manufacturer (usually 2-4 hours)
  7. Spot prime any repairs or touch-ups

Walls:

  1. Same process as ceiling
  2. Work top to bottom
  3. One room at a time (maintain wet edge)

Trim (if painted, not stained):

  1. Lightly sand all trim (120 or 150-grit)
  2. Wipe clean
  3. Prime with quality trim primer
  4. Fill any gaps or nail holes after priming
  5. Spot prime filled areas

Days 5-8: First Coat

Painting technique basics:

Cutting in (edges with brush):

  1. Load brush 1/3 to 1/2 way up bristles
  2. Start 2-3" from edge, brush toward edge
  3. Smooth back toward center
  4. Create 3-4" wide band along all edges
  5. Do 4-6 feet at a time, then roll before it dries

Rolling (main areas):

  1. Load roller evenly (not dripping)
  2. Roll in "W" or "M" pattern
  3. Fill in the pattern with parallel strokes
  4. Maintain wet edge (work quickly enough that edges don't dry)
  5. Don't press too hard (creates texture)
  6. Back-roll lightly to even out

Sequence:

  1. Ceiling first (work toward light source)
  2. Walls second (top to bottom)
  3. Trim last (after walls dry)

Common painting errors to avoid:

Days 9-12: Second Coat and Trim

Second coat walls (after 4-24 hours drying):

  1. Same process as first coat
  2. Should cover much better (primer sealed surface)
  3. May only need one coat of quality paint
  4. Touch up any missed spots

Ceiling (if needed):

Trim painting (semi-gloss usually):

  1. Lightly sand between coats (220-grit)
  2. Cut in at edges carefully
  3. Use smooth strokes following grain
  4. Two coats typical for trim
  5. Let first coat dry 4-6 hours minimum

Doors:

  1. Remove doors from hinges (easier to paint flat)
  2. Paint panels first, then stiles and rails
  3. Long smooth strokes
  4. No heavy brush marks
  5. Let dry horizontal (prevents runs)

Days 13-14: Touch-ups and Cleanup

Touch-ups:

  1. Inspect all walls with bright light (raking angle shows imperfections)
  2. Touch up any holidays (missed spots)
  3. Fix any drips or runs
  4. Touch up any damage from trim installation

Remove tape:

Cleanup:

  1. Remove all drop cloths
  2. Reinstall outlet and switch covers
  3. Remove protective coverings
  4. Touch up any paint on windows or hardware
  5. Wash brushes and rollers (or dispose of cheap ones)
  6. Dispose of paint responsibly (dried out or recycling center)

Paint Quality and Selection

Paint quality matters:

Budget paint ($20-$25/gallon):

Mid-grade paint ($35-$50/gallon):

Premium paint ($50-$80/gallon):

💡Pro Tip

Buy quality paint. The labor cost (your time) is the same whether you apply cheap or premium paint. Premium paint covers in fewer coats, lasts longer, and looks better. The $15-$30/gallon premium is worth it.

Sheen selection:

Exterior Painting

Exterior is more complex:

If DIY exterior:

  1. Pressure wash entire house
  2. Scrape loose paint
  3. Sand rough areas
  4. Prime bare wood and stains
  5. Caulk all gaps and joints
  6. Apply 2 coats quality exterior paint
  7. Work in shade (paint won't dry properly in direct sun)

Exterior timeline: 1-3 weeks depending on house size and complexity

My recommendation: Hire exterior painting unless you're comfortable on tall ladders and have scaffolding access. The $3,000-$6,000 cost includes all prep, equipment, and expertise.

What's included:

Common Mistakes

1. Skipping Primer

Why it's a problem: Poor coverage, more coats needed, uneven finish, paint peeling. How to avoid: Always prime new drywall, bare wood, and repairs. No exceptions. Cost if you don't: Extra paint coats, poor results, potential repainting.

2. Cheap Paint

Why it's a problem: Poor coverage, requires many coats, doesn't last, looks bad. How to avoid: Buy quality paint ($35-$50/gallon minimum). It's worth it. Cost if you don't: More coats needed, earlier repainting, poor appearance.

3. Inadequate Prep

Why it's a problem: Paint doesn't adhere, bumps and ridges show through, unprofessional results. How to avoid: Fill all holes, sand smooth, clean thoroughly before painting. Cost if you don't: Amateur appearance, may need to sand and repaint.

4. Wrong Roller Nap

Why it's a problem: Poor coverage, texture issues, visible roller marks. How to avoid: 3/8" for smooth walls, 1/2" for light texture, 3/4" for heavy texture. Cost if you don't: Extra coats needed, texture issues.

5. Not Maintaining Wet Edge

Why it's a problem: Lap marks visible (dried paint edge shows through). How to avoid: Work quickly enough to keep edge wet. Don't let cut-in edges dry before rolling. Cost if you don't: Visible lap marks, may need extra coat.

6. Painting Over Dirty Surfaces

Why it's a problem: Paint doesn't adhere, peels later. How to avoid: Clean all surfaces before painting. Wipe down drywall dust, grease, etc. Cost if you don't: Peeling paint, repainting needed.

7. Wrong Sheen Selection

Why it's a problem: Sheen too high shows imperfections, too low isn't washable. How to avoid: Flat ceilings, eggshell/satin walls, semi-gloss trim. Standard formula that works. Cost if you don't: Repainting with correct sheen.

8. Not Enough Coats

Why it's a problem: Old color or primer shows through, uneven appearance. How to avoid: Two coats minimum for walls, check coverage before declaring complete. Cost if you don't: Amateur appearance, need to repaint.
