Winter's rolled around again, and you might be wondering if it's worth taking on that painting project you've been putting off. Good news: winter is actually a fantastic time for painting, especially here in Sydney where our winters are pretty mild compared to other places.

Interior Painting is Perfect Right Now

You can paint indoors in winter, even with cold temperatures and rainy weather. You've got complete control over the temperature and conditions. This makes for excelling working conditions and top-quality results.

Lower Humidity

Winter offers some real advantages for indoor painting. The humidity levels are lower, which speeds up drying times compared to sticky summer days.

Controllable temperature

Keep your place between 10-30°C to allow paint to adhere better and dry faster. Regular latex paint typically dries in about 4 hours between coats in ideal conditions, but in winter's lower humidity, you might find it dries even faster indoors. Just make sure you've got adequate air circulation by opening doors and windows when possible, or using fans if needed.

Better finish

Some types of paint dry slower in the cold, which gives it time to level out properly. Additionally, closed windows mean less dust and pollen can get in. This adds to a cleaner finish.

Possible off-peak discounts

Moreover, the colder months are often the off-peak season for painters, potentially leading to cheaper quotes and better scheduling flexibility.

Pro tip: Don’t make the hourly cost of painters your number decision-maker. Experienced painters are more expensive for a good reason.

What About Outdoor Painting?

Exterior painting in Sydney winter can definitely be done since winter temperatures are milder than in colder climates. The key is to understand the challenges and plan accordingly.

Never paint when it's below 10°C: that's your golden rule. Most quality acrylic paints can be applied down to 10°C, with some specialty products formulated for even lower temperatures.

Sydney rarely drops that low during the day, but you need to think about night-time temperatures too.

Cold weather affects paint in several ways:

• Extremely low temp makes paint thicker and slows down both drying and curing times.
• When temperatures drop below 10°C, drying time for regular latex paint can extend from about 4 hours to 6 hours or longer between coats.
• Cold can also prevent paint from curing properly. This can lead to common paint problems like poor adhesion, cracking, or peeling down the track.

Planning for the weather is everything. You need several consecutive dry days where temperatures stay above the minimum required by your paint.

Sydney's winter rain can be unpredictable, and getting caught by a shower before your paint has dried can cause streaking, bubbling, or blistering.

Dew and frost from those chilly winter mornings can also soak into unsecured paintwork and cause staining or adhesion problems.

Timing matters. Paint during the warmest part of the day, typically around midday. This gives surfaces time to warm up and paint time to dry before temperatures drop at night. Make sure surfaces are clean and completely dry before you start. After winter rain, allow plenty of time for walls to dry out properly.

How Paint Reacts to Cold

Different paint types handle the chill differently. Here's a quick rundown:

Oil-Based Paints (Alkyd):

These paints get thick and gloopy when it's cold. You'll need to use more thinners to get them flowing properly and spreading evenly.

Water-Based Paints (Latex):

These can actually freeze solid in really cold conditions because they take longer to dry off. You can add special additives to stop them from freezing up on you.

Additives that can help:

• Frost-resistant additives help your paint dry even when it's cold
• Quick-dry undercoats and fast-curing paints are ideal for painting outdoors
• Thinning additives stop paint from getting too thick and hard to spread

Better quality paint also handles the cold better. The quality of finish and ease of application is how you can really tell the difference between premium and budget paint.

Getting the Details Right

Surface temperature is just as important as air temperature. Walls can be significantly colder than the air around them, especially on overcast winter days. Professional tradies use an infrared thermometer helps you measure this accurately. You want surfaces warm enough for proper paint adhesion and curing.

For outdoor work, consider using cold-weather specific paints or additives that are formulated to cure at lower temperatures.

Paint can become thicker in cold weather, so you might need paint conditioners to make it easier to apply evenly. Using rollers and brushes designed for thicker paint also helps.

Indoor ventilation deserves special attention in winter. While you need air circulation for paint to dry properly, you don't want to let all your heat escape.

Strategic use of internal doors, fans, or even carefully positioned heaters can help maintain the right conditions. Low-VOC latex paints are particularly good for winter indoor projects when windows might be closed more often.

For larger outdoor projects, you can plan in sections that can be completed within dry weather windows. Some professional painters even create heated "bubbles" over painting areas using plastic tarps and heaters. These bubbles can keep temperatures between 15-20°C throughout the drying period.

If you find mould, don't paint over it. Use commercial or home-made solutions to prepare mouldy walls for painting.
