A successful exterior paint job is a sequence, not a single event. Miss a step — or do them out of order — and you pay for it in adhesion failures or wasted weekends. This checklist covers every phase from planning to final touch-up, in the order the work should actually happen. Before you begin, lock in your quantities with the Open the Exterior Paint Calculator.
Phase 1: Planning and Measuring
- Measure every wall (length × height), including gables and garage — use the estimating guide worksheet
- Count and deduct windows (~15 ft² / 1.4 m² each) and doors (~21 ft² / 2.0 m² each)
- Identify your siding material and pick the correct coverage rate
- Calculate primer, two finish coats, and trim separately
- Decide DIY vs pro — see the DIY vs pro guide
- If pre-1978: test for lead paint and review code compliance before disturbing anything
- Check HOA color approval or historic-district rules; get written approval
Phase 2: Buying Materials
- Choose paint type and sheen per surface — see the material guide (100% acrylic latex body, semi-gloss trim is the classic combo)
- Buy all paint at once; box (intermix) gallons of the same color
- Round every quantity up to the full gallon; keep one spare gallon of body color for touch-ups
- Stock primer, caulk, wood filler, sandpaper, tape, drop cloths, brushes, and rollers
- Confirm VOC compliance for your region on the product data sheet
- Budget check: compare against the cost guide ranges
Phase 3: Preparation
- Pressure-wash all surfaces; allow 24–48 hours to dry
- Scrape all loose and peeling paint to sound edges
- Sand feather edges smooth (80–120 grit)
- Repair or replace damaged wood, fill holes and cracks
- Caulk joints (trim-to-siding, window/door casing) — never the bottom edge of horizontal siding
- Mask windows, doors, fixtures, and landscaping; lay drop cloths
- Spot-prime every bare patch the same day it’s exposed (tint primer toward finish color)
Phase 4: Painting
- Check weather: 50–85°F (10–30°C), humidity under ~70%, no rain within 4–6 hours
- Start after morning dew dries; follow the shade around the house
- Paint in order: soffits and fascia → body siding → trim and doors
- Maintain a wet edge; apply two thin coats, not one thick one
- If spraying, back-brush or back-roll into the surface for adhesion
- Respect recoat times on the can (typically ~4 hours for latex)
- Keep a wet-edge log if the job spans multiple days — note where you stopped
Technique details that separate good from great are in the pro tips guide.
Phase 5: Inspection and Touch-Up
- Walk the full perimeter in daylight; check for misses, drips, and thin spots
- Touch up with the boxed original paint, not a fresh can
- Remove masking promptly; inspect caulk lines and cut-in edges
- Photograph the finished job and record paint brand, product, color formulas, and sheens
- Label and store leftover paint in a climate-controlled space for future touch-ups
- Clean tools properly; dispose of waste per local rules (never into storm drains)
Phase 6: Maintenance Schedule
- Annual: visual walk-around each spring; wash off dirt and mildew
- Every 2–3 years: re-caulk failing joints, touch up south/west exposures
- Every 8–15 years: full repaint depending on climate, exposure, and siding material
- Keep gutters and flashing sound — water intrusion kills paint jobs faster than sun
Frequently Asked Questions
How long does a full exterior repaint take?
A pro crew: 3–7 days on an average home. DIY: typically 2–4 weekends, heavily dependent on prep.
What should I do first — wash or scrape?
Wash first. Pressure washing removes loose material and reveals what actually needs scraping.
Can I skip primer if I’m using paint-and-primer-in-one?
On previously painted sound surfaces, yes. On bare wood, bare masonry, or heavy stains, use a dedicated primer — combination products aren’t a substitute there.
When can I put the shutters and fixtures back?
After the final coat has cured per the data sheet — usually 24–48 hours, longer in cool or humid weather.
What’s the one step people skip most?
Caulking. It’s tedious, invisible when done right, and critical for keeping water out of the wall assembly.
How do I handle a project that spans multiple weekends?
Finish complete sections (whole walls, not partial ones) each work session so stop points land at natural breaks like corners. Seal paint cans tightly between sessions, keep brushes wrapped airtight or cleaned, and note exactly where you stopped. Never leave a wall half-coated through a rainstorm — an unfinished coat edge can show as a lap mark permanently.
Avoiding Checkout Mistakes
The store trip is where good estimates go wrong. Run through this before you pay:
- Verify every can’s color formula matches — one mistinted gallon in a boxed batch tints the whole batch.
- Confirm sheen on each label: satin body and semi-gloss trim look identical in the can.
- Count lids and labels: primer, body, trim, and accent colors are four separate products — make sure none was substituted.
- Buy the caulk, tape, and sandpaper now, not on a second trip mid-prep.
- Ask the store to shake every can, including the spare for touch-ups.
Documentation to Keep
File these with your home records — future painters, buyers, and your future self will need them:
- Paint brand, product line, color name/number, formula, and sheen for every color
- Primer product used and where it was applied
- Contractor name, license number, and warranty terms (if hired)
- Lead test results and renovator certification (pre-1978 homes)
- HOA or historic-district written color approval
- Dated photos of bare-wood repairs and finished work
- Receipts with quantities — they prove what was actually applied
Good records turn the next repaint from a research project into a reorder. If anything in the regulatory column is unclear, revisit the code compliance guide before work begins.
