House Painting Preparation: What Proper Prep Involves

Preparation is the part of a painting project that decides how the finish looks and how long it lasts. It is also the part most often reduced when a quote is unusually low.

Interior preparation

  • Clear and cover furniture; protect floors across all work and traffic areas
  • Clean surfaces, especially in kitchens, bathrooms and high-traffic hallways
  • De-gloss any previously glossy or oil-based finish
  • Fill nail holes, cracks and dents; sand flush
  • Spot-prime all repairs so they do not flash through the finish
  • Caulk trim gaps and mask edges for clean cut lines

Exterior preparation

  • Wash to remove dirt, chalking, pollen and organic growth, then allow to dry fully
  • Scrape and sand loose coatings back to a sound, feathered edge
  • Repair or replace deteriorated wood before any coating goes on
  • Prime all bare and repaired areas with an appropriate exterior primer
  • Caulk joints and penetrations after priming, not before
  • Protect windows, walkways, landscaping and adjacent surfaces

What homeowners can do in advance

  • Decide colours and sheens before the start date
  • Clear small items, wall hangings and window coverings
  • Point out known problem areas such as past leaks or persistent cracks
  • Arrange access, parking and pet containment
  • Trim vegetation away from exterior walls before the crew arrives

Warning signs in a quote

A quote that lists surfaces and colours but says nothing about washing, repair, priming or protection has left the largest variable undefined. Ask for the preparation to be described in writing — it is the fairest way to compare two prices.
