Yes, vinyl siding can be painted if done correctly with the right preparation, paint, and application techniques. Using premium 100% acrylic exterior paints that are vinyl-safe is crucial. Painting with a darker color than the original vinyl color is generally not recommended unless the paint is specifically formulated to handle the heat absorption, to avoid warping. Thorough cleaning of the siding before painting is essential to remove dirt, mildew, and oxidation. The preferred application method is spraying the paint for an even finish, avoiding brushing or rolling. Proper weather conditions and timing when the house is in an expanded state help to avoid visible gaps after expansion. Painted vinyl siding can last many years if these guidelines are followed with quality paint and preparation.
