Peeling paint on your steps can be an eyesore, but it's a common issue with a variety of causes, from excess moisture to poor surface preparation. Before you start repairing, it's important to determine whether the paint contains lead, especially if your home was built before 1978–1979. If you suspect lead-based paint, do not attempt to repair it yourself; instead, hire a professional. If there's no lead, you can start by removing the peeling paint with a paint scraper or wire brush, being careful not to damage the underlying surface. Once the peeling paint is removed, you can fill any cracks or holes with a patching compound or filler, and sand the area to ensure a smooth finish. After cleaning the area, apply a primer to ensure better adhesion and prevent future peeling. Finally, you can repaint the area, using thin, even coats and allowing each coat to dry thoroughly before adding the next.

What You'll Learn
Identify the cause of peeling paint
Peeling paint on steps can be caused by a number of factors. One of the most common causes is moisture, especially in high-moisture areas like bathrooms. If the steps are in an area with high humidity, the moisture can cause the paint to peel.
Another cause could be poor surface preparation. If the steps were not properly cleaned, or if there was leftover wallpaper glue or dust, dirt, or grease on the surface before painting, it could prevent the paint from adhering properly and cause it to peel.
Incompatible paints or primers can also cause peeling paint. For example, applying a latex paint over an oil-based paint without proper priming can lead to peeling.
Other possible causes include natural aging and wear, or the use of low-quality paint that does not adhere well to the surface.

Prepare the surface
Preparing the surface is the most important step in repairing peeling paint. It ensures that the new paint adheres properly and that the repair is durable. Here is a step-by-step guide to preparing the surface:
Remove Old Paint and Clean the Surface
Use a scraper or stripping knife to gently remove any loose, cracked, or peeling paint from the damaged area. Be careful not to damage the surface underneath. For stubborn areas, a wire brush can help remove remaining paint. After removing the paint, clean the area with a damp cloth or a damp lint-free cloth to remove any dust, dirt, or debris. If there is wallpaper glue residue, apply a wallpaper stripper solution and scrub the walls with a coarse scouring pad. Rinse the area with clean water and allow it to dry completely.
Sand the Surface
Lightly sand the edges of the remaining paint with fine-grit sandpaper (100-220 grit) to create a smooth transition between the bare and painted areas. Sanding will also help to remove any irregularities or patches from where the paint has peeled off. It is important to ensure that the surface is as smooth and even as possible before proceeding to the next steps.
Apply a Primer
Priming the surface is crucial, especially if you are working with incompatible paint types, such as latex over oil-based paint. Choose a primer suitable for your surface, such as an oil-based, stain-blocking primer or a multi-surface primer. Apply the primer with a paintbrush or a roller, following the manufacturer's instructions. Allow the primer to dry completely before proceeding to the next step. Priming will help your paint adhere better and will prevent future peeling, cracking, or flaking.
Repair Any Cracks or Holes
Identify and repair any cracks or holes in the surface to create a smooth surface for an even layer of paint. Small cracks or holes can be filled using a patching material or joint compound applied with a putty knife. Allow the compound to dry and then sand the area to smooth it out and make it even with the surrounding surface. For larger repairs, you may need to use a filler or spackle to level the surface.
Prepare the Surrounding Area
Before proceeding to paint the steps, it is important to prepare the surrounding area to avoid accidental paint streaks or splashes. Use masking tape to protect windows, trim, outlet covers, and light switch covers. You may also want to remove furniture and cover the floor with drop cloths to catch any paint drips or spills. Ensure the work area is well-ventilated by opening windows and using fans if necessary, especially if working with old paint that may contain lead.

Remove loose paint
Before you start removing loose paint, it is important to understand why your paint is peeling. Identifying the root cause can help you prevent the problem from recurring. Peeling paint can be caused by excess moisture, poor surface preparation, or ageing. Incompatible paint layers can also cause peeling, such as applying latex over oil-based paint without proper priming.
Now that you know the potential causes of peeling paint, you can begin the process of removing the loose paint. First, put on safety goggles and a dust mask, especially if your house was built before 1979, as it may contain lead paint. You should also ensure your work area is well-ventilated by opening windows and using fans. Next, use a paint scraper or wire brush to gently remove the peeling paint. Be careful not to damage the surface underneath. For stubborn areas, you can use a heat gun on a low setting to soften the paint before scraping. After you have removed the loose paint, sand the edges of the remaining paint with fine-grit sandpaper to create a smooth transition between the bare and painted areas. Finally, clean the area with a damp cloth to remove any dust or debris.

Sand the surface
Sanding the surface is an important step in repairing peeling paint. It helps to create a smooth transition between the bare and painted areas, ensuring a seamless finish. Here is a step-by-step guide to sanding the surface:
- Choose the Right Sandpaper: Select a fine-grit sandpaper, such as 150-grit or 220-grit, for a smooth finish. Avoid using too coarse a sandpaper, as it may damage the surface.
- Sand the Edges: Focus on the edges of the remaining paint. Gently sand the area to blend the transition between the bare surface and the painted sections. Take your time and work carefully to avoid creating an uneven surface.
- Wrap Sandpaper Around a Sanding Block: For larger areas or flat surfaces, consider wrapping the sandpaper around a sanding block. This provides a comfortable grip and helps apply even pressure across the surface.
- Sand in One Direction: For the best results, sand in a consistent direction. Avoid circular or random sanding patterns, as they may create swirl marks or an uneven finish.
- Remove Dust and Debris: After sanding, use a damp cloth or a dampened rag to wipe down the sanded surface. Ensure all dust and debris are removed, as these particles can interfere with the adhesion of the new paint.
- Repeat as Needed: Depending on the severity of the peeling paint and the condition of the surface, you may need to repeat the sanding process. Lightly sand the area again with the fine-grit sandpaper until you achieve the desired smoothness.
Remember to wear protective gear, such as a dust mask and goggles, to safeguard yourself from dust and paint particles during the sanding process.

Apply primer
Before applying primer, it is important to understand why paint peels. Paint can peel for several reasons, including excess moisture, poor surface preparation, or ageing. Incompatible paint layers, such as applying latex paint over oil-based paint without proper priming, can also cause peeling.
Once you have identified the cause of the peeling paint, you can move on to the priming step. First, prepare the surface by removing any loose, cracked, or peeling paint from the damaged area using a scraper or sandpaper. Be careful not to damage the underlying surface. Then, remove any dust or debris from the area with a damp rag or cloth. If there is wallpaper glue residue, apply a wallpaper stripper solution and scrub the walls clean using a coarse scouring pad. Rinse the area with clean water and allow it to dry completely.
Now, you are ready to apply the primer. Choose a primer that is suitable for the surface you are working on. For example, if you are repairing peeling paint on a metal surface, use a metal primer such as ENDURAPRIME®. If you are repairing peeling paint caused by wallpaper glue residue, use an oil-based primer to seal in any remaining water-based glue and prevent future peeling. Apply the primer to the repaired area using a paint roller or brush, following the manufacturer's instructions. Allow the primer to dry completely before moving on to the next step, which is usually painting.
It is important to note that priming is a crucial step in the painting process. Skipping this step can result in a temporary paint job, as primer helps ensure better adhesion and longevity of the paint. Additionally, if you are working on an older home, take the necessary safety precautions as the paint may contain lead. Wear goggles and a dust mask to protect yourself from dust and paint particles, and ensure the work area is well-ventilated.
