How to Paint Shoe Molding
Painting shoe molding gives it a clean, uniform appearance and allows it to match your baseboards and other painted trim. Whether you are painting before or after installation, proper preparation makes the difference between a smooth, professional-looking finish and a sloppy one.
Before or After Installation?
Both approaches work, and each has advantages:
- Before installation: Easier to get smooth, even coverage. No need to tape off the floor. You can lay pieces across sawhorses and paint all sides. Touch up nail holes and corners after installation.
- After installation: Allows you to caulk the top edge and fill nail holes first, so the final paint coat covers everything. Requires careful taping or cutting-in along the floor.
A common approach is to prime and apply the first coat before installation, then fill nail holes, caulk, and apply a final topcoat after everything is in place.
Preparation
- Sand the shoe molding lightly with 150-grit sandpaper. This smooths the surface and helps paint adhere.
- Wipe down with a tack cloth or damp rag to remove dust.
- If the molding is bare wood, apply a coat of primer (latex or shellac-based). MDF molding usually comes pre-primed. PVC molding may not need primer — check the manufacturer's instructions.
- After primer dries, lightly sand with 220-grit for a smooth base.
Painting
- Use a good-quality acrylic latex trim paint in a semi-gloss or satin finish. Semi-gloss is the traditional choice for trim because it is durable and easy to clean.
- Apply with a small brush (2-inch angled brush works well) or a small foam roller for long, straight runs.
- Apply two thin coats rather than one thick coat. Sand lightly with 220-grit between coats if you want the smoothest possible finish.
After Installation Touch-Up
Once the shoe molding is installed:
- Fill nail holes with lightweight spackling compound
- Sand the filled spots smooth
- Caulk the top edge where the molding meets the baseboard
- Apply a final coat of paint over everything for a seamless look
