To paint an exterior steel door, follow these steps:
Clean the door thoroughly with a degreaser. Lightly sand the door and wipe it down to remove any lingering dust. Apply the first coat of primer and let it dry. (Apply a second coat if necessary). Apply at least two coats of exterior satin or semi-gloss paint. Let the paint dry completely, then rehang the door.
Prepare the door for a smooth and long-lasting finish. A well-prepared door will not only look better but also help protect the metal from the sun. Primer can be applied directly to the door if it comes pre-primed. If the surface is bare metal or has any bare sections, you will need to apply it.
Remove the door, remove hardware and cover areas that won’t be painted. Sand the door lightly, remove all sanding dust and debris left behind, and apply primer. Apply two layers of paint, allowing each to fully dry in between. Roll on one to two coats of primer with the foam roller. Allow the primer to dry for about 30 to 60 minutes between coats.
For doors out of direct sunlight, two or more coats of high-quality exterior acrylic-latex paint are ideal. Glossier paints like acrylic-latex or oil-based enamels provide excellent adhesion, durability, and better adhesion. Roll on one light coat of exterior paint on the flat areas of the door and use an angled brush for any recessed or beveled panel areas.

- Start by gently wiping down the door to remove any dust or debris. Lightly sand the entire door surface using a fine grit sand paper. Prime the surface with a water-based primer, as oil-based primers can interact with the zinc in galvanized metal, causing premature peeling.

I can’t stress this enough but when you plan to paint metal doors, it is vital to first primer those doors in an oil based primer!
Can you paint over peeling paint on metal?
To prevent paint peeling from a painted galvanized metal surface, it is recommended to remove all peeling paint before repainting. Apply chemical stripper, wait for the paint to bubble off, and use a scraper to chip off the paint. Prime the surface before applying a new coat. If working with a new or unpainted surface, remove the protective oil or passivator layer to prevent paint from peeling. Clean a small test area with a water-based or solvent-based cleaner, then test the clean galvanized area with a copper sulfate solution.
If the surface does not turn black, remove the passivator using SSPC-SP7 to coat the substrate. Avoid hydrocarbon solvents, which leave a thin residue that can cause paint film adhesion failure. Use a water-based cleaner or degreaser instead. Most acrylic coatings will adhere directly to cleaned galvanized metal. Remove white rust from weathered galvanized surfaces using a wire brush or scrubbing. Apply primer to bare steel the same day it is cleaned, and replace severely rusted gutters.
What happens if you paint metal without primer?
Painting metal is a challenging task due to its sensitivity to rust and oxidation. To control rust and weathering, it is essential to use a paint formulated for metal. Metal paints come in oil-based and water-based brush-on or spray-can versions. Oil-based paint is harder to work with but offers longer-lasting results. Water-based acrylic paints are more forgiving but may be difficult to find for exterior use. Spray-can paint is the easiest way to paint metal, especially for pieces with multiple contours like patio furniture or wrought-iron fences or railings.
However, the finish is not as smooth and uniform as brush-on paint, and it may take several coats to achieve the desired finish. Good ventilation and a respirator are essential when spraying paint. Brush-on paint takes longer to apply but provides a smooth and durable finish. Both water-based and oil-based versions are widely available.
Can I paint my front door without sanding it?
It is possible to paint a front door without sanding if the paint or varnish is intact and smooth. Nevertheless, in the event of substantial damage, such as significant nicks, flakes, or dents, it is advisable to sand these areas prior to painting. This will help to prevent the paint from flaking off, cracking, or peeling.
Can I paint raw steel?
Raw steel legs can be painted to prevent rust and provide a simple and affordable way to customize them. If you prefer the raw steel look, use a clear coat instead of colored spray paint. The process should be done outside or in a well-ventilated area. Use rust-oleum spray paint, Rust-oleum Clean Metal Primer Spray, Acetone, rag or paper towels, Scotch brite pad, or any raw steel product. To clean, wipe thoroughly with acetone and let dry. If acetone is unavailable, Windex can be used.
Do you need to sand a steel door before painting?
Steel doors are factory-primed and do not require additional priming. To paint them, wipe them clean with a solvent and allow it to dry completely. After sanding, wash with mild detergent, rinse, and dry. Apply two coats of quality exterior paint with good blocking resistance to all surfaces and door panel edges. Paint can be brushed or sprayed on. Apply paint to various door components, such as door edges, brickmould, jambs, mullions, glazing frames, and wood frames.
Clean the brush and wait at least six hours between each coat. The finish must be completely dry before applying the next coat. Do not sand between coats. Repeat Steps 1 – 4 for each additional coat applied. This will ensure the door panel’s grain texture is not hidden.
How to repaint a metal door that is peeling?
This document outlines the process of removing paint from a galvanized metal surface, addressing issues such as improper surface preparation, failure to use a primer, and failure to sand baked-on enamel finishes or glossy surfaces. The process involves removing loose paint, cleaning the exposed metal of contaminants, treating them with an etching liquid, rinsing the surface with clean water, applying a galvanized metal primer, and then repainting with a high-quality paint. It emphasizes the importance of proper surface preparation and proper sanding before applying paint.
How do you paint an unfinished steel door?
This guide provides a step-by-step guide on how to paint a worn, scratched, or tired-looking steel door. The process involves removing the door, removing hardware and covering areas that won’t be painted, sanding the door lightly, removing all sanding dust and debris, applying primer, and applying two layers of paint, allowing each to fully dry in between.

The process involves removing the door, removing hardware and cover areas that won’t be painted, using a degreaser to clean the door well, sanding the door lightly, removing all sanding dust and debris, and applying primer. Steel doors are durable and can last a lifetime, but their paint may not last as long. Therefore, if your client has a metal front door, they will eventually need to repaint it. The preparation of the project will directly impact the final results, but this is not a difficult DIY task.
Can you paint a metal door without primer?
One common error is the omission of a primer, which serves to prepare the surface for subsequent paint coats by providing a protective barrier and enhancing pigment adhesion. In the absence of a primer, the durability and longevity of a painted surface may be compromised, resulting in an uneven and less robust finish. To rectify this issue, it is necessary to sand the door, reapply the appropriate primer, and repaint. Furthermore, the use of paint that is not specifically designed for metal surfaces can result in the deterioration of the coating through color chipping or peeling.
Do I need to strip metal door before painting?
In order to remove peeling or flaking paint from a metal door, it is recommended that an aerosol paint stripper or a heat gun be used to strip the paint before repainting.
📹 The Fastest Way to Paint a Door with a Brush
Do you have a bunch of doors to paint, and it seems like it takes too long? If you want to “Go Fast,” you’ve come to the right place.
ive painted abunch of doors like this we never primed them but we also used oil base direct to metal paint. id use a 9 inch mohair roller and a purdy oxhair oil brush to cut it in and id dab everything i cut in to give it more of a stipple look instead of brush lines and id add about a cap full of naptha to a pan full of paint after i thinned it alittle with mineral spirits and that would make it dry alittle faster. i got good at doing them almost to where they looked sprayed. dont miss commercial painting one bit though lol
