Why the Best Paint Jobs Start Long Before the First Coat

Most homeowners assume pressure washing is all that's needed to prepare an old wood porch for paint. Sometimes that's true. Often, it isn't.

At Henderson Custom Painting LLC, we let the condition of the wood determine the preparation—not the calendar.

In the project shown here, the porch was first power washed to remove dirt, mildew, chalking, and loose paint. Once the surface dried, it became clear that years of weathering had left stubborn, failing paint that remained tightly attached but was no longer a sound surface for a new coating.

Rather than paint over it, we mechanically sanded the porch decking to feather rough edges, remove additional failing paint, and expose a more stable substrate.

But we didn't stop there.

After sanding, we performed a second power wash. Why? Because sanding often loosens paint that wasn't ready to release during the initial wash. The second cleaning removes sanding dust while also revealing any remaining weak paint that needs additional attention before primer and finish coats are applied.

This extra step isn't required on every project, but when conditions warrant it, it provides a significantly better foundation for a long-lasting finish.

You can see that process in these photos. The decking has already been sanded, and our crew is performing the second wash before moving on to repairs, priming, and painting.

We often refer to this approach as the Cadillac of wood surface preparation. It requires more time and labor, but exceptional paint jobs are built on exceptional preparation.

Because in painting, the finish is only as good as the surface beneath it.
