The benefits of painting UPVC windows

UPVC windows have become increasingly popular due to their durability, energy efficiency, and low maintenance requirements. However, typically most window manufacturers produce a plain white finish, which may not always suit everyone’s taste.

That’s where painting comes in.

By painting your UPVC windows, you can transform their look and ensure they complement the overall aesthetic of your home. Not only does this allow for greater customisation, but it also offers the opportunity to give your home a fresh, modern look without the need for expensive window replacements.

But, there is another option. At Sealtight Windows, we design our windows for you and your taste and offer our windows in a variety of different colours and finishes to suit your preference.


Factors to consider before painting UPVC windows

Before diving into the world of painting UPVC windows, it’s important to consider a few factors.

Let’s go through the main factors below:

  • Warranty on your windows: Some manufacturers may void the warranty if the windows are painted. Please be aware, we at Sealtight windows do not recommend you to paint your windows if you have bought these through us.
  • Assess the condition of your windows: Are they in good shape, or do they require repairs? It’s essential to address any issues before painting to ensure a smooth finish.
  • Climate in which you live: Extreme temperatures or high humidity can affect the drying process and the longevity of the paint job.


Step-by-step guide to preparing UPVC windows for painting

Preparing UPVC windows for painting is crucial to achieving a flawless finish.

Here is a step-by-step guide to help you through the process:

  • Clean the windows: Start by thoroughly cleaning the windows to remove any dirt, dust, or grime. Use a mild soap and warm water, along with a soft cloth or sponge. Rinse the windows with clean water and allow them to dry completely.
  • Sand the surface: Next, lightly sand the surface of the windows using fine-grit sandpaper. This helps to create a rough surface, allowing the paint to adhere better. Be sure to wipe away any dust with a clean cloth.
  • Apply a primer: Apply a high-quality UPVC primer to the windows. This provides a smooth base for the paint and improves its adhesion. Follow the manufacturer’s instructions for application and drying times.
  • Choose your paint: Select a paint specifically formulated for UPVC surfaces. This type of paint is designed to expand and contract with the windows, preventing cracking or peeling. Consider the desired colour and finish of your windows and choose a paint that matches your preferences.
  • Paint the windows: Use a high-quality brush or roller to apply the paint evenly to the windows. Start with the edges and corners, then move on to the larger surfaces. Apply multiple thin coats rather than one thick coat for a smoother finish. Allow each coat to dry completely before applying the next.
  • Finishing touches: Once the paint is dry, inspect the windows for any areas that may require touch-ups. Use a small brush to fix any imperfections and ensure a flawless finish.


Choosing the right paint for UPVC windows

Choosing the right paint for UPVC windows is crucial to achieving a flawless finish that lasts. You should be looking for a paint specifically formulated for UPVC surfaces. This type of paint is designed to withstand the unique properties of UPVC, such as expansion and contraction due to temperature changes.

You should also opt for a paint that offers UV protection to prevent fading and discoloration over time. Consider the desired colour and finish of your windows to select a paint that best suits your aesthetic preferences.

Techniques for painting UPVC windows

When it comes to painting UPVC windows, there are various techniques you can employ to achieve a flawless finish.

Here are a few techniques to consider:

  • Brush painting: Brush painting is a traditional method that allows for precise control. Use a high-quality brush and apply the paint evenly in smooth strokes, following the grain of the UPVC. This technique works well for small areas and detailed sections.
  • Spray painting: Spray painting is a popular technique for larger surfaces or when working with multiple windows. It provides a uniform finish and can be more efficient than brush painting. However, it requires careful masking and protection of surrounding areas to prevent overspray.
  • Roll and tip: The roll and tip method involves using a roller to apply the paint and then using a brush to smooth out any imperfections or bubbles. This technique is particularly useful for achieving a smooth, brush stroke-free finish.


Common mistakes to avoid when painting UPVC windows

While painting UPVC windows can be a rewarding project, there are some common mistakes that should be avoided to achieve a flawless finish.

Here are a few to keep in mind:

  • Skipping the preparation: Properly preparing the windows is crucial to a successful paint job. Skipping steps such as cleaning, sanding, and priming can result in poor adhesion and a less durable finish.
  • Using the wrong paint: Using the wrong type of paint can lead to cracking, peeling, or fading over time. Always choose a paint specifically formulated for UPVC surfaces to ensure longevity and optimal performance.
  • Applying too thick of a coat: Applying a thick coat of paint may seem like a time-saver, but it can result in uneven drying, drips, and an overall poor finish. Opt for multiple thin coats instead, allowing each coat to dry completely before applying the next.
