To paint over painted wood floors, you must first prepare the surface by sanding and cleaning it thoroughly.
Preparing Painted Wood Floors for Repainting
Surface Preparation
Preparing your painted wood floor is crucial for ensuring the new paint adheres properly and provides a durable, attractive finish. Follow these detailed steps to get your floor ready:
1. Sanding
If your wood floor has been previously painted or stained with a glossy finish, sanding is necessary. This process helps to dull the existing surface, creating a better grip for the new paint.
- Materials Needed:
- Medium-grit sandpaper (120- to 150-grit)
- Sanding sponge or block
- Process:
- Attach the sandpaper to your sanding block or use a sanding sponge.
- Lightly sand the entire floor surface. The goal is to remove the gloss and create a slightly rough texture, not to remove the existing paint entirely.
- Focus on areas with noticeable wear or unevenness to ensure a uniform surface.
2. Cleaning
After sanding, it's essential to remove all dust and debris to ensure a clean surface for painting.
- Steps:
- Vacuum thoroughly to remove all sanding dust and loose particles. Pay special attention to corners and edges where dust tends to accumulate.
- Mop the floor using a damp mop and a mild cleaner suitable for wood floors. This helps to remove any remaining dust and residues.
- Allow the floor to dry completely before proceeding to the next step. Any moisture left on the floor can interfere with the paint's adhesion.

Additional Tips
- Ventilation: Ensure the room is well-ventilated during the sanding, cleaning, and painting processes. Open windows and use fans to improve airflow.
- Protection: Wear a dust mask and safety goggles during sanding to protect yourself from dust and debris.
- Even Application: When applying primer and paint, use smooth, even strokes to avoid streaks and ensure a uniform finish.
- Drying Time: Follow the manufacturer's recommendations for drying times between coats of primer, paint, and sealant.
