If possible, remove the steel door from its hinges. Lay it flat on a pair of sawhorses to prevent drips. If removal isn't practical, you can still paint the door vertically but be extra cautious to avoid runs.
Use a degreaser or mild soap solution to clean the door. This step is crucial to remove any oils, dirt, or manufacturing residues. Hele Doors’ products from their steel door factory come clean and ready for minimal prep, but cleaning ensures the best results.
Lightly sand the door with medium-grit sandpaper to remove the gloss and create a surface the primer will adhere to. Follow up with fine-grit sandpaper for a smooth finish.
Apply a thin, even coat of high-quality metal primer using a foam roller. Priming is essential, especially if you are painting a steel door for exterior use. A good primer helps prevent rust and improves paint adhesion.
Using the best paint for a steel door, apply thin, even coats with the foam roller. Start with the panels (if any), then move to flat sections. Allow each coat to dry completely before applying the next.
Tip: Thin coats minimize drips and create a smoother finish.
After the final coat dries, inspect the surface under good lighting. Use a small brush or foam applicator to touch up any missed spots for a flawless finish.
