What You Will Need
- Paint stripper
- Wire brush
- Sandpaper (medium and fine grit)
- Primer
- Paint (choose a high-quality paint suitable for metal surfaces)
- Paintbrush or paint sprayer
- Dust sheets or newspaper
- Masking tape
- Protective gloves and goggles

Step 1: Prepare the Area
Start by placing dust sheets or newspaper around the area where you will be working to protect the floor from any paint or debris. Additionally, open windows or provide proper ventilation in the room to ensure good airflow.
Step 2: Strip the Old Paint
Before you can apply a new coat of paint, you need to remove any existing paint. Apply paint stripper following the manufacturer’s instructions, and allow it to sit until the paint starts to bubble. Once the paint has bubbled, use a wire brush to scrape off the old paint. Be sure to wear protective gloves and goggles during this step.
Step 3: Smooth the Surface
After removing the old paint, use sandpaper to smooth the surface of the cast iron radiator. Start with a medium grit sandpaper to remove any remaining paint or rough spots, and then switch to a fine grit sandpaper for a smoother finish. Wipe away any dust with a clean cloth.
Step 4: Apply Primer
Applying a primer is essential to ensure proper adhesion and long-lasting paint on the cast iron surface. Use a high-quality metal primer and apply it evenly onto the surface of the radiator. Allow the primer to dry completely according to the manufacturer’s instructions.
Step 5: Paint the Radiator
Once the primer is dry, it’s time to paint the cast iron radiator. Choose a paint suitable for metal surfaces and apply it using a paintbrush or paint sprayer. Start painting from the top and work your way down, being careful to apply an even coat. Allow the first coat to dry completely before applying a second coat if needed.
Step 6: Finishing Touches
After the final coat has dried, carefully remove any masking tape. Inspect the radiator for any drips or imperfections and touch up as necessary. Allow the paint to cure completely before turning on the radiator.
