Exterior painting projects can vary depending on the age and condition of the home, but there are common steps and missteps that can make all the difference in the final result.

Do: Clean and Prep the Surface Properly

A clean surface is critical for ensuring that new paint adheres correctly. Power washing, scraping off peeling paint, and sanding rough areas will help create the ideal base. Prepping also includes sealing gaps and repairing damaged siding.

Don’t: Paint Over Dirty or Damaged Areas

Applying paint to dirty, wet, or deteriorating surfaces can trap moisture and cause blistering or peeling. Even high-quality paint will not perform well without proper preparation. Taking shortcuts during this phase often leads to costly do-overs down the road.

Do: Use the Right Paint and Tools

Exterior paints are formulated to withstand different weather conditions, so choosing the right type for your climate and surface is key. Using the appropriate brushes, rollers, or sprayers also ensures smoother application and better coverage across large areas.

Don’t: Paint in Poor Weather

Painting during high humidity, rain, or extreme heat can impact drying times and finish quality. That is why timing is everything. Understanding the best times of year to paint your home’s exterior (typically spring and early fall) helps ensure the paint cures properly and delivers long-lasting results.
