Why Paint Interior uPVC?
uPVC, or unplasticised polyvinyl chloride, has long been a popular material for doors and windows due to its durability and low maintenance. However, like any surface, it can become dull or outdated over time. Painting the inside of your uPVC front door or window frames can give your space a new lease of life and create a more cohesive design with your interiors – whether it’s at home or at work. We’ve never met a small business owner that isn’t proud of their workspace!
Many homeowners and businesses focus on the exterior of their property, but the inside of your front door and windows also play a crucial role in your overall aesthetic. Whether you want to match your door with your skirting boards or introduce a bold colour statement, painting your uPVC surfaces can bring harmony and style to your living space.
Preparation is Key
Before you begin painting the inside of your uPVC front door or window frame, preparation is essential. uPVC is a smooth material, which means that without proper prep, paint might not adhere well, leading to peeling or chipping over time. By taking these preparatory steps, you’ll help the paint adhere properly, ensuring a longer-lasting finish:
Clean the Surface Thoroughly
uPVC tends to collect dust and grime over time. Start by wiping down your surfaces with a mixture of warm water and mild detergent to remove any dirt, oil, or debris.
Sand the Surface Lightly
Once the surface is dry, use fine-grit sandpaper to lightly roughen the surface. This will create a better bonding surface for the paint.
Wipe Away Dust
After sanding, clean off any dust with a damp cloth and allow it to dry completely before proceeding to the next step.
Choosing the Right Paint for Interior uPVC
When it comes to painting uPVC, selecting the right product is crucial. Not all paints are suitable for uPVC surfaces, and using the wrong type could result in poor adhesion or a finish that doesn’t stand the test of time. Fortunately, there are excellent multi-surface paints available that are specifically formulated for uPVC, and they can also be used on wood and metal surfaces such as doors, window frames, skirting boards, and even furniture. Always read the manufacturer’s product data sheet for its recommended application, preparation, and any primers or cleaners required.

Painting the Inside of a uPVC Front Door
Now that your surfaces are prepped, and you’ve chosen the right paint, it’s time to begin painting. The inside of your front door can be a focal point in your hallway, so choosing a complementary or contrasting colour can elevate your entryway.
Steps to Paint the Inside of Your Front Door:
Apply a Base Coat (if necessary)
Some paints, like the ones mentioned above, do not require a separate primer. However, if you’re working with a bare or particularly glossy surface, a base coat might help enhance the topcoat’s durability.
Paint the Panels First
Start by painting the recessed panels of your door. Use a brush to apply paint evenly, working from the edges inward. This ensures any excess paint can be smoothed out as you go.
Move to the Larger Surfaces
Once the panels are done, switch to a roller for the larger areas. Roll in even strokes to avoid drips and ensure a smooth finish.
Leave to Dry
Check the manufacturer’s instructions for drying times, but most water-based paints dry in as little as two hours. Solvent-based paints may take longer, so plan accordingly.
Painting the Inside uPVC Window Frame
Painting the inside of a window frame presents a few more challenges than painting a door, as it involves more intricate surfaces. However, with the right approach, you can achieve a beautiful result.
Steps to Paint Inside a Window Frame:
Mask Off the Glass
Protect the glass with masking tape and paper to avoid getting paint on it. Precision here will save time on clean-up later.
Use a Small Brush for Detail
For the trim and smaller sections of the frame, use a small, angled brush. This will allow you to get into tight corners and edges without making a mess.
Roll the Larger Sections
If the frame has wider sections, use a mini roller to apply paint evenly. This ensures you get a smooth, brushstroke-free finish.
Check for Drips
Because windows often have grooves and corners, check for any paint drips as you go. Wipe them away with a damp cloth or sponge before they dry.
Finishing Touches and Curing Time
Once you’ve applied the paint, be sure to allow enough time for the surfaces to fully cure. Even though the paint might feel dry to the touch within hours, it can take several days to harden fully. During this time, be gentle with your doors and windows to avoid damaging the fresh coat.
Conclusion
Painting the inside of your front door and window frames can significantly enhance the look and feel of your home or business. With the right preparation, tools, and materials, it’s a manageable DIY project that delivers professional results. Whether you’re going for a bold, modern look or a subtle, cohesive design, the products recommended here will ensure a durable, long-lasting finish.
