Prepare the area around the soffit you are painting by placing a drop cloth over any exposed concrete. Cover bushes in the area as well. Attach the drop cloth around pillars, if there are any in the area, by securing the drop cloth with painter's tape.
Scrape away old, flaking paint and fill holes and cracks with wood filler, applied with a putty knife, before painting. If there are areas that are rough and need to be smoothed out, use sandpaper to smooth.
Paint the soffit with primer and allow the coat to dry thoroughly before placing the first top coat of paint on the soffit.
Using a brush or a roller, paint the soffit with the house paint of your choice. Select paint that is for outdoor surfaces. Soffits are usually painted the same color as the siding of the house.
Paint the fascia after the soffit is complete. Fascia is the vertical trim piece between the eave and the soffit.
