If you want to give your uPVC doors a makeover, you’ll need the right supplies and some knowledge. So what paint and primer should you use?

A paint specifically made for hard plastics is best, and a primer specifically designed for plastic should be applied first to help the paint adhere better and last longer. A finish with a semi-gloss or gloss sheen is best for durability since it will be more resistant to scratches and fading from the sun.

4 Factors to Consider When Choosing Paint for uPVC Doors

When it comes to painting uPVC window frames, there are a few factors to consider before you start (don’t miss my full guide to painting uPVC window frames). Here are some of the most important things to keep in mind:

1. Quality of the Paint

The quality of the paint is important when painting uPVC window frames. You want to ensure that the paint you choose will adhere properly and last a long time. Look for paints specifically designed for plastic surfaces and that have good reviews from other users.

2. Finish

The paint’s finish is also an important factor to consider. Most paints come in matte, satin, or gloss finishes, so you can choose one that best suits your environment, needs, and preferences. Gloss finishes are more durable and easier to clean than matte or satin finishes.

3. Color Selection

Color selection is also an important factor to consider when choosing paint for uPVC window frames. You can find a variety of colors, from classic white and everything in between. Be sure to select a color that complements the overall look of your home or office space.

4. Flexibility

Another important factor is the flexibility of the paint. uPVC window frames expand and contract in response to temperature changes.

Therefore, the chosen paint must be flexible enough not to crack or peel off as the frame expands and contracts in response to external temperatures.

What Type of Paint Is Best?

Oil-based paint

Oil-based paint is a type of paint that uses oil as its main binder. It is often used for exterior painting projects due to its durability and resistance to weathering.


  • Durable and resistant to weathering
  • More resistant to fading, cracking, and peeling than water-based paints
  • Provides a smoother finish


  • More difficult to apply than water-based paints
  • Higher VOC content
  • Longer drying time

Water-based paint

Water-based paint is a great option for exterior painting projects. It is eco-friendly, odorless, and has a wide range of color options, making it easy to find the perfect color for your home.


  • Easy cleanup
  • Eco-friendly and low-VOC content
  • Dries faster than oil-based paints
  • Wide range of colors available


  • Less durable than oil-based paints
  • More susceptible to cracking, peeling, and fading

What Paint Finish is Best?

One of the most important considerations when choosing a finish for uPVC doors is how well it stands up to the elements.

The four main finishes for uPVC doors are matte, satin, semi-gloss, and high-gloss. A higher gloss is generally best for durability and longevity in outdoor exposure.

High-gloss finishes offer superior protection against UV rays and other weathering effects such as rain, snow, and wind.

This means that your door won’t fade or become discolored over time. In addition to superior durability, high-gloss finishes provide a visually appealing aesthetic that many homeowners enjoy thanks to its reflective shine. 

Matte finishes are less durable than their glossier counterparts, but they still offer some protection from UV exposure and other environmental factors.

While matte finishes will eventually require recoating or refinishing due to wear from sunlight or moisture exposure, they’re generally easier to clean and maintain than higher glosses.

Satin finishes lie somewhere between matte and glossy regarding protection against the 

elements. They balance aesthetics and durability, making them ideal for many uPVC door applications.

Satin’s subtle sheen makes it attractive without making it overly shiny or reflective, as higher glosses can be. Its light sheen also makes it more resistant to fingerprints and smudges than higher glosses while still providing moderate protection from UV rays compared to mattes. 

Semi-gloss finishes are less popular than the other finishes, but they may be preferable if you want something with more shine than satin but less reflection than high-gloss.

However, they don’t reflect as much light as higher glosses. Semi-gloss paints are slightly more durable outdoors because they provide better resistance against fading due to UV radiation than matte options.

The Best Paint and Primer for uPVC Doors

When considering what type of paint to use on uPVC doors, there are a few things to remember. Firstly, it is important to determine if the paint is suitable for the door’s material.

You must also pick a paint specifically designed for outdoor use, as the UV rays in sunlight can cause regular interior-grade paints to fade quickly. 

Spray paint can be used on uPVC doors and is often recommended because it gives an even layer of paint without leaving brushstrokes or other marks behind.

However, because of the nature of spray paint, extra care must be taken when using this method, as each coat should go on evenly rather than having patches of thicker and thinner areas.

Additionally, because spray painting creates overspray, you must cover any surrounding surfaces with plastic sheeting and wear safety gear such as protective glasses and gloves before beginning.
