How to Avoid Lap Marks When Painting Vinyl Siding

Open one gallon of paint and mix in one cup of paint additive conditioner. Mix it thoroughly with the paint using a paint stir stick.

Pour the mixed paint into a 5-gallon bucket. Hang a metal paint roller screen from the inside edge of the bucket. Dip a mini roller into the paint and roll the roller up and down on the metal paint roller screen until the nap fibers are loaded with paint.

Carry the bucket and roller to the shady side of the house and roll the vinyl siding. Roll one siding slat at a time. Hold the roller handle so the roller cover is vertical on the horizontal piece of vinyl siding. Roll 2 to 3 feet of the vinyl at a time. Roll back and forth, keeping even pressure on the roller length. This minimizes lap marks resulting from the edges of the roller cover.

Roll back over the 2- to 3-foot section just as soon as you have rolled it once to smooth out any lap marks. Follow the shade around the home until all vinyl siding is painted.
