How to Paint the Overhang on a House

by Si Kingston

An overhang not only adds to the architectural design, but it can also shade the windows and porch from sunlight. Weather destroys the paint on many overhangs over time. The sun will often fade the overhang paint, and rainwater will cause it to peel. A peeling overhang is unsightly, and can devalue your home or building. You can fix this problem with a fresh coat of paint.

Items you will need

  • Bucket or pump sprayer
  • Bleach
  • Sponge
  • Pressure washer or garden hose
  • Sandpaper
  • Trisodium phosphate
  • Oil or latex primer
  • 2 stirring sticks
  • 2 paintbrushes, 3 to 4 inches
  • Exterior paint
  • Ladder
Step 1

Fill a bucket or pump sprayer with a solution of one part bleach and three parts water.

Step 2

Apply the solution to the overhang trim down with a sponge or the sprayer to remove any mildew. Rinse the trim with a garden hose or power washer.

Step 3

Smooth any uneven surface or peeling paint from the overhang with sandpaper.

Step 4

Mix trisodium phosphate with water in a bucket or pump sprayer. Read the manufacturer's instructions for the correct amount of trisodium phosphate to add to the mixture. Spray off the sand particles from the surface with a power washer or garden hose. Allow the overhang to dry completely.

Step 5

Prop a ladder against the building so you have access to the overhang.

Step 6

Open an oil or latex primer paint can, and stir it with a stirring stick. Oil primer adheres better to wood surfaces than latex. Latex is often preferred to paint overhangs that are not composed of wood.

Step 7

Climb the ladder with the paint and a 3- to 4-inch paintbrush. Attach the paint can to the ladder hook.

Step 8

Apply the primer onto the overhang with the paintbrush and allow it to dry.

Step 9

Apply another coat of primer to the overhang and allow it to dry.

Step 10

Open the can of exterior paint and stir it with a stirring stick.

Step 11

Apply the paint to the overhang with a 3- to 4-inch paintbrush.
