Tools and materials needed for painting an interior door

• Spray paint (Maston ONE)
• Primer (Maston ONE)
• Clear coat (Maston ONE or e.g. Maston Metallic Clear Coat)
• Degreaser (Maston Degreaser)
• Spray handle (for easier application on large surfaces)
• Sandpaper (grit 180) or a sander
• Painter’s tape
• Protective paper or plastic
• Screwdriver
• Protective gear (mask, gloves, safety glasses)

Step-by-step instructions for painting an interior door:

1. Preparation

• Make sure the door surface is suitable for painting. Maston ONE spray paint adheres to most materials, including wood, MDF, laminate, plastic, and various metals.
• Choose a well-ventilated area for painting.
• Cover surrounding areas to protect them from paint overspray.

2. Remove the Door and Hardware

• Use a screwdriver or appropriate tools to remove the door and all hardware such as handles and hinges.
• Label each part to make reassembly easier.
• If desired, you can also paint handles or pulls. For better durability on high-wear parts, remember to apply a clear coat.

3. Clean and Sand the Surface

• Thoroughly clean the surface to remove grease and dirt.
• Lightly sand the surface with 180-grit sandpaper to improve paint adhesion.
• Wipe down the surface using Maston Degreaser.

4. Apply Primer

• Test the paint on a hidden area first.
• Apply 2–3 thin coats of Maston ONE primer. This ensures better adhesion and creates an even base.
• Allow the primer to dry according to the instructions on the can.

5. Paint the Door

• We recommend using Maston ONE acrylic spray paint, which dries quickly and provides excellent UV protection for a long-lasting result.
• Spray evenly in light coats.
• Let each layer dry before applying the next. Typically, 2–3 coats provide good coverage.
• For improved durability, apply two coats of clear coat after painting. Follow the instructions on the product.

(In the example video, Maston Metallic Clear Coat was used for a subtle sparkling finish.)

• A spray handle can make painting easier and can be reused with any spray can.

6. Reassemble the Door

• Once the paint is completely dry, reattach all hardware.
• Remove protective coverings and clean the workspace.
• Install the door back in place.

Tips for Best Results

• Always work in a well-ventilated area to avoid inhaling fumes.
• Test the spray paint on a small, inconspicuous area to ensure the desired color and finish.
• Take your time with each step to achieve a high-quality result.

By following these instructions, you can refresh your home’s look without major renovations. Spray painting is a cost-effective and relatively easy way to update your interior elements.
