Materials and Tools Needed
- List of Materials
For the painting project, one will need a variety of materials to ensure a successful outcome. Begin by getting a rust-inhibitive primer such as Diamond Vogel’s CoteAll Multi-Purpose Alkyd Primer or Iron Prime 600 Fast Dry Universal Primer, which is crucial for areas with severe surface oxidation.
Additionally, an acrylic latex topcoat like Diamond Vogel’s Palisade Ultra Premium Exterior Acrylic Latex is recommended for long-term durability. For cleaning, trisodium phosphate can be used to effectively remove grime and rust, but ensure to have protective gear due to its caustic nature.

- Essential Tools
The proper tools are essential for a smooth and efficient painting process. A high-pressure washer (2500 psi minimum) is essential for removing loose dirt, chalk, and contaminants from the metal siding. For the application of paint, a reliable paint sprayer or a paint roller with an extension can be used, depending on the type of primer chosen. Additionally, to handle rust and loose coatings, one should have tools for scraping, sanding, or other abrading methods ready.
Step-by-Step Cleaning Process
- Removing Dirt and Grime
Begin the cleaning process by diluting a mild detergent or trisodium phosphate TSP in water to create a cleaning solution. This solution is effective for general cleaning and removing light dirt build-up on metal siding. For more stubborn grime, a stronger solution may be necessary, and for pre-painted metal, products like Glass Wax or a similar cleaner are recommended. Always start spray chemical on the siding from the bottom of the panel and work upwards to prevent streaking, and rinse thoroughly with clean water to avoid leaving any residue.
After spray cleaning solution pressure wash the surface with 3000 psi pressure washer to remove dirt and film from old siding with fades.
- Dealing with Rust
For areas with rust, start by using a wire brush to scrub off flaky and powdery surface rust. If the metal is heavily rusted, consider using a drill with a wire wheel or a rust converter to treat and prepare the surface. For extensive rust, products like Evapo-Rust® or OSPHO can be used to remove rust without scrubbing; just immerse the rusted items in the solution and then rinse. Ensure all rusted areas are treated with a rust-inhibitive primer before painting.
- Final Cleaning and Drying
After addressing dirt and rust, ensure that all surfaces are rinsed well with water to remove any cleaning agents or loose debris. Use a soft cloth or sponge for a final wipe-down to ensure no cleaner or water spots are left behind, which could affect paint adhesion. Allow the metal siding to air dry completely, which might take several hours depending on the weather conditions. Before proceeding with painting, a final inspection should be done to ensure the surface is clean, dry, and free of imperfections.
Painting Techniques and Tips
- Spraying vs. Rolling
When painting exterior metal siding, choosing between using a paint sprayer or a roller is crucial. Sprayers offer a smooth, even finish and are excellent for large, flat surfaces due to their ability to provide uniform coverage without brush strokes. However, rollers might be preferable for those who need more control over paint application, especially on smaller or detailed areas. Rollers are also noted for their ability to apply paint more thickly, which can be beneficial for achieving even coats on porous surfaces.
- Best Practices
For optimal results, always start with thorough surface preparation. This includes cleaning the siding to remove all dirt, mildew, and loose paint, and then sanding any rough sections. Skipping this step can lead to peeling or cracking of the paint. When applying paint, whether spraying or rolling, ensure each coat is thin and even to prevent drips and uneven textures. If using a sprayer, remember that while the actual spraying may be faster, the preparation may take longer, balancing out the time needed.
- Common Mistakes to Avoid
One of the critical errors in painting metal siding is using the wrong type of paint, which can result in poor adhesion and durability. Always select a high-quality exterior paint that is suitable for metal surfaces. Additionally, do not rush the drying time between coats. Each layer needs sufficient time to dry completely to ensure proper adhesion and a flawless finish. Lastly, using low-quality tools can lead to a below an average level finish, so investing in high-quality brushes, rollers, or sprayers is recommended.

Pressure washing and then continue the cleaning process by removing all loose dirt, chalk, and other contaminants from the siding.
