With any home improvement or business renovation, weather will play a significant role in determining the right time to carry out the work. When it comes to UPVC spraying, a common question asked is whether or not it is appropriate to spray paint UPVC whilst it’s raining, or what sort of impacts these wetter conditions might have on the finished result. In this article, we will explore why the weather, specifically rain, can affect the spraying process and why it’s essential to consider the conditions before proceeding with your UPVC spraying project.

Why does rain affect UPVC spraying?

While it might seem like a small detail at first, rain will have a significant impact on the success of your UPVC spray paint projects.

Moisture interferes with paint adhesion

UPVC spray paint is designed to adhere to the surface of the material, creating a smooth and durable finish. However, when it rains, moisture can interfere with the paint’s ability to bond effectively. Water on the surface can cause the paint to bubble, run, or even peel off entirely once it dries. For a professional finish, it’s essential that the surface is completely dry and clean before spraying begins.

Extended drying times

Rain increases the humidity levels in the air, which can significantly extend the time it takes for the paint to dry. This can leave the painted surfaces vulnerable to smudges, dust or other environmental elements that can damage the freshly applied coat. In some cases, this may even require touch-ups or the need to redo sections of the job.

Risk of uneven coverage

Spraying UPVC when it’s wet or raining increases the risk of uneven coverage. The paint may not go on smoothly, leaving patches or streaks on the surface. Additionally, if droplets of rain hit the surface while the paint is still drying, they can create imperfections or water spots.

Should you ever spray paint UPVC in the rain?

While rain is generally not ideal for UPVC spraying, there may be some exceptions. In general, you will want to spray paint UPVC in dry conditions of around 4°C or higher. However, as stated there may be a few conditions in which it might be possible to effectively spray paint during wetter weather.

• Light drizzle – If rain is intermittent, spraying may still be possible with proper precautions. The surface must remain dry, and professionals may use tarpaulins or covers to shield it from moisture.
• Indoor spraying – Spraying indoors in areas with proper ventilation, such as in a garage or workshop, eliminates weather concerns, ensuring optimal conditions for a smooth finish.
• Using weather-resistant paint – Some UPVC spray paints are designed to withstand light rain, drying faster and offering better durability. However, avoiding rain whenever possible is still recommended.

How to ensure successful UPVC spraying in the right weather

If you’re planning to have UPVC spraying done, it’s essential to pick the right day and time for the job. Ensuring the process is carried out successfully requires careful planning, preparation and proactivity.

Check the weather forecast

Before scheduling your spraying, make sure you check the weather forecast. Ideally you want a dry day with minimal humidity which your usual weather reporting channels or apps will be able to give insight on. If rain is forecasted, it’s best to reschedule for another day than risk spraying to achieve less-than-perfect results.

Plan for dry conditions

Aim to complete the spraying on a day when the weather is forecasted to be dry and calm. This will allow the paint to adhere properly and dry without interference from moisture. A temperature of 4°C or higher is ideal for UPVC spray painting, as it prevents the paint from drying too quickly or too slowly. Most professional UPVC spray painters will ask you to book several weeks in advance, so make sure you plan for time ahead.

Use protective covers

If you’re working in an area where there’s a chance of rain, consider using tarpaulins or other covers to protect the surfaces being painted, whether that be windows, doors, conservatories or whatever else. These can help shield the painted areas from rain while still allowing you to get the job done during unpredictable weather.
