​There is a suggested temperature application range for all paints. Depending on the type of paint (water, oil, or solvent), the brand, and whether the paint is intended for internal or outdoor usage, this varies amongst various paints. So in this blog post, we’ll cover whether you can spray paint UPVC windows in Winter.

What are good temperature ranges?

Perfect conditions

Applying spray paints while the air temperature is between 12°C and 30°C is a reasonable general rule of thumb. The paint won’t dry out too quickly or too slowly in this temperature range. It will adhere to the UPVC with the aid of a slow drying process.

Does the paint type affect temperature?

With ordinary plastic paint, 12°C is about as low as you want to go. But, if you use solvent-based paint, you may apply it down to 8°C.

Unsuitable conditions

At temperatures below 8°C, UPVC spray painting in Cardiff is impossible without compromising the finish’s quality. Drying times are slowed down in cold weather, and re-coat times are prolonged. Also, dew often forms during colder weather and this can completely ruin the finish. It’s also a similar reason why we can’t spray paint in the rain.

Does a solvent-based paint help?

A solvent-based paint should always be used to paint UPVC. This is because the solvents in the paint produce the durable finish required for windows, doors, fascia, and gutters. Furthermore, it’s not necessary to use a plastic primer before painting because the solvents in the paint also serve as a bonding agent.


It’s crucial to take the weather into account in addition to the temperature range. Therefore, painting UPVC should only be done in dry conditions. Ideally on cloudy days or in the shade to prevent the paint from drying out too soon. So, you can spray paint UPVC windows in Cardiff in any season as long as the air temperature is between 12 and 30 degrees Celsius, or between 8 and 30 degrees Celsius for solvent-based paint. We hope this clarifies your inquiry. But if it hasn’t then don’t hesitate to give us a call in Winter, rain or shine and we’ll give you whatever information you need.
