Winter Application Tips for Andura Wall Coatings: Ensuring Quality Results in the Cold Weather

Applying wall coatings during winter can be tricky, especially in the UK, where temperatures can drop to freezing levels. Yet, with the right approach, you can achieve excellent results even when it's cold outside. This blog post offers practical advice on using Andura wall coatings during winter, guiding you toward successful and durable projects.

Understanding Temperature Limitations

To ensure the effective use of Andura wall coatings, you first need to understand their temperature limitations. Most solvent-based coatings, like the Classic Smooth range, require a minimum application temperature of 5°C. If the temperature dips below this, issues such as poor adhesion can occur, resulting in peeling or flaking. For instance, in areas that regularly see winter temperatures around 0°C, it is vital to plan ahead and apply coatings only when the forecast shows stable temperatures above 5°C.

Preparing the Surface

Surface preparation is critical, especially during the chillier months. The surface should be cleaned, dry, and free from frost or ice. If frost or moisture is present, use a heat gun or a blow heater to dry the area before application. According to studies, poor surface preparation can reduce coating lifespan by 30% or more. This means taking the time to ensure the surface is ready could save you from future headaches.

Choosing the Right Products

Selecting the appropriate products is essential for winter applications. The Classic Smooth solvent-based coating is an optimal choice for cold months, praised for its durability and weather resistance. Additionally, using a specialised low-temperature primer can significantly improve adhesion and performance.

Application Techniques

Effective application techniques can make a big difference. Use a high-quality brush or roller for an even coating. Avoid applying thick layers, as this can trap moisture and slow down drying. Instead, aim for two or three thin coats, allowing each to dry fully before applying the next. This method has been shown to improve curing outcomes, especially in cooler temperatures, making it more likely that the finish will last.

Monitoring Weather Conditions

Understandably, it is hard to determine the weather conditions within the UK as it can vary dramatically. However, it is crucial to keep a close eye on weather forecasts during your application. Select days when temperatures are steady and there is no rain or snow expected for at least 24 hours. For example, if you anticipate a sudden drop in temperature within a few hours, consider delaying your project. As stated on our product labels, Andura coatings should not be applied when rain is imminent, during frosty or foggy weather, when air or substrate temperature is below 5C or where these conditions may occur before the coating has dried. Low temperatures and high humidity will considerably lengthen drying times. A significant temperature fluctuation can lead to complications like incomplete curing. Overall, this leads to future problems and ongoing problems with the properties.

Post-Application Care

After applying your Andura coatings, protecting the newly coated surface is key. If possible, cover the area with tarps or plastic sheeting, especially if rain or snow is expected. This precaution will help gases escape and allow the coating to cure correctly, especially in conditions where humidity is high or temperatures are low. Ensure ventilation is possible to avoid condensation forming on the inside of the plastic covering.

Summing It All Up

Winter applications of Andura wall coatings can be successful with adequate preparation and techniques. Understanding temperature limitations, preparing surfaces correctly, choosing appropriate products, and monitoring weather conditions can help you achieve a high-quality finish that endures. Approach these projects thoughtfully, and you’ll ensure that your winter work remains not only successful but also visually appealing.
