What Are the Best Techniques for Painting Vinyl Siding?

Because vinyl is a low-maintenance type of siding product, it usually does not need painting. However, if the vinyl has faded, you need to know the steps for painting it. Before painting the siding, you will need to clean it. It is always important to clean any surface first to make sure the paint goes on smoothly. Do not paint over any buildup of dirt or grime.

Prep the Surface by Cleaning It

To start the process, clean the siding with a mix of two thirds of a cup of trisodium phosphate (TSP), one third of a cup of laundry detergent, and one gallon of water. Take a soft bristle brush, used for cleaning a car, and dip it into the cleaning solution. Gently scrub the vinyl siding, working from bottom to top. Follow the practice by rinsing off the solution with a hose, beginning at the top and working down.

Hosing the Grime and Dirt

When hosing down the vinyl siding, you should use a pressure washer that has been set at a medium spray, or use a garden hose with a nozzle-type spray. If you choose to use a pressure washer, make sure the spray pattern is wide enough to prevent any damage. Keep the nozzle constantly moving. Begin washing at the bottom and work up before rinsing from top to bottom. To avoid any water drips behind the siding, make sure you are directing the spray toward the overlapping joints.

Selecting a Paint

When you paint vinyl siding, you need to make sure you are using the right type of paint. In this case, the paint should be a premium exterior brand that is made of acrylic latex. Do not paint the siding a darker hue than the siding’s original or factory color. Doing so may cause the material to retain too much heat. If this occurs, the siding will end up warping.

Therefore, you do not want to choose just any paint when you are painting vinyl siding. For the paint to look good and endure, you must select a paint with the following characteristics:

  • As noted, the paint should contain acrylic as well as urethane resins. That is because these kinds of ingredients complement the expansion and contraction of the material, thereby helping the paint to adhere.
  • The paint needs to be either the same shade as the vinyl or a lighter color. As indicated, when vinyl is painted too dark of color, it will naturally retain excess heat, thereby leaving the material susceptible to warping. Darker colors can create unanticipated maintenance issues.

Do Not Use a Primer

Primer is not needed on vinyl unless the vinyl color has eroded, is displaying pits, or has become porous. Otherwise, you simply need to choose a paint and begin painting. Use a roller or a paint sprayer for the project. A brush can be used for the edges and corners of the wall.

Evenly Apply the Paint

Evenly apply the paint and be careful not to apply too much paint in any one area of the siding. Like most paint jobs, it is best to apply several thin coats rather than one or two thicker coats.

After you finish the first coat, permit the paint to dry before applying the second coat. Make sure the second coat has dried for 24 hours before finishing the painting assignment.
