Can You Paint UPVC Doors?

Revamping your uPVC door with a fresh coat of paint can instantly enhance your home's exterior, but proper preparation and technique are essential for a long-lasting finish. Cleaning the door thoroughly, selecting the right paint, and applying painter's tape with care are key steps to ensure professional results. Choosing high-performance products like Dulux Weathershield and adhering to ideal weather conditions will help prevent flaking and peeling. From prepping the surface to adding finishing touches, these guidelines will make painting your uPVC door a rewarding DIY project. With the right approach, your door will look fresh and withstand the elements for years to come.

Cleaning and Preparing the Door

Gather necessary tools:

• Bucket
• Sponge
• Dust sheet
• Sandpaper
• Dusting brush
• Masking tape
• Primer
• Paint
• Stirring stick
• Paintbrush

Remove dust and dirt with a brush. Wash the door with warm soapy water and let it dry completely. Sand lightly to create a key for the paint, focusing on window frames. Cover handles and details with masking tape.

Pro tip: Mix the primer and paint well with the stirring stick before use for optimal results.

Choosing the Right Paint for uPVC

Use paint designed for challenging surfaces, such as Dulux Weathershield quick-dry satin or gloss range. Start with Dulux Difficult Surface Primer for better adhesion.

Important: Apply on days when the temperature is above 10°C for proper drying. Avoid regular paint, as it won't adhere well to uPVC and may lead to flaking and peeling.

Select paint products that promise durability and high performance on uPVC surfaces. Remember, the right paint choice is crucial for a long-lasting finish.

Applying Painter's Tape and Removing Accessories

Clear the area around the door of objects and accessories. Tape up all hardware including:

• Handles
• Peepholes
• Letterboxes

Use good quality painter's tape to prevent paint bleeding. Press the tape down firmly to create a seal.

"Proper preparation is the key to a professional finish. Take your time with taping - it's worth the effort."

Painting the uPVC Door

1. Stir the paint thoroughly.
2. Apply the first coat, which acts as a primer.
3. Add one or two more coats for full coverage.
4. Paint in smooth, even strokes to avoid brush marks.

Work on mild days with temperatures above 10°C. Start at the top of the door and work downwards to prevent drips. Maintain consistent brush or roller strokes throughout.

Important: Allow each coat to dry completely before applying the next. Sand and touch up any imperfections between coats.

Once fully dry, carefully remove the painter's tape.

Ensuring Long-lasting Results

Avoid painting uPVC doors less than twelve months old, as resins can interfere with paint adhesion.¹ Use paints that can handle thermal expansion and contraction, especially for sun-facing doors. Choose UV-stable paints to prevent fading.

Caution: Check your door's warranty before painting, as DIY interventions may void it.

Aftercare Tips:

• Clean the door regularly with a damp cloth and mild soap
• Avoid harsh chemicals and abrasive materials
• Address chips or scratches promptly to prevent further deterioration

By following these guidelines, you can significantly extend the life and appearance of your painted uPVC door.
