Can I Paint Over Polyurethane Without Sanding? Step-by-Step

Polyurethane is a popular coating for many home furnishings. However, painting over polyurethane can be difficult if not done properly. If you don’t prepare the surface correctly, the paint will peel off, wasting your time and effort. To successfully paint over polyurethane, it’s important to follow the right steps. In this blog post, we will discuss what polyurethane is, the supplies you need for painting over it, and the step-by-step process for achieving a successful outcome.

What is Polyurethane?

Polyurethane is a hard and durable topcoat that is applied to various materials such as kitchen cabinets, wood floors, doors, and furniture. Its purpose is to protect these surfaces from scratches and scuffing. Additionally, it creates a high-gloss finish that is typically achieved by applying multiple coats for enhanced durability. Repainting kitchen cabinets with a polyurethane finish is a common challenge faced by DIYers.

Recommended Supplies for Painting Over Polyurethane

Before you start painting, make sure you have the following supplies on hand to ensure a smooth and successful process:

  • Clean, lint-free cloths
  • Mineral spirits
  • Wood filler
  • Protective face mask
  • Gloves
  • Protective eyewear
  • Fine-grade sandpaper
  • Liquid sandpaper (optional)
  • Paintbrushes
  • Oil-based primer
  • Oil-based paint or acrylic urethane topcoats (if you can’t find oil-based paint)

Remember to gather these supplies before you begin painting over polyurethane.

How to Paint Over Polyurethane

Now that you have all the necessary supplies, let’s dive into the step-by-step process of painting over polyurethane:

The Recommended Safety Guidelines

To ensure your safety while painting kitchen cabinets, it is important to follow these guidelines:

  1. Wear Protective Gear: Put on gloves, a mask, and eyewear to protect your hands, lungs, and eyes.
  2. Work in a Well-Ventilated Area: Make sure you are working in a space with proper ventilation.

Step 2: Remove Cabinet Doors, Drawers, and Hardware

If possible, remove the cabinet knobs and any other hardware. For a small number of cabinets, you may leave the doors in place. However, if you have multiple cabinets, it is best to remove the doors for easier access.

Step 3: Clean and Sand the Surface

To prepare the cabinet for painting, follow these steps:

  1. Clean the Cabinet: Use mineral spirits and a lint-free cloth to wipe the cabinet in a circular motion. This will remove dirt, grime, and stains, creating a better surface for paint adhesion.
  2. Fill Gaps and Scratches: Fill any gaps or scratches with wood filler.
  3. Sand the Cabinet Door: Use fine-grade sandpaper to remove the polyurethane from the cabinet door. You don’t need to remove all of it, just enough for the new paint to adhere. Continuously remove dust with a clean cloth and mineral spirits. Alternatively, you can use liquid sandpaper following the instructions on the bottle.

Step 4: Prime the Surface

To ensure proper paint adhesion and prevent stains from bleeding through, apply oil-based paint primer. Allow the primer to dry overnight for best results. If any wood grain or stain shows through, an additional coat may be necessary.

Step 5: Paint the Surface

Follow these steps to paint the cabinet door:

  1. Apply the First Coat: Start painting with the first coat and let it dry overnight.
  2. Apply the Second Coat: Apply a second coat to ensure full coverage of the cabinet door. Allow this layer to dry for up to 72 hours before adding any hardware.
