Plastering in a Heatwave

Someone asked me “How do these instances of super high temperatures in the UK affect plastering and What can you do about it? Can you still come and do the work?”

High temperatures in the UK can affect plastering in several ways:

1. Faster Drying: High temperatures can cause plaster to dry more quickly. This can be problematic because it may not give you enough time to properly work with the plaster, leading to a rough finish or cracks.

2. Increased Risk of Cracking: Rapid drying due to high temperatures can also increase the likelihood of cracks forming in the plaster. These cracks can be unsightly and may require additional repair work.

3. Reduced Workability: Hot weather can make plaster harder to work with as it can become stiffer and less malleable, making it challenging to achieve a smooth and even finish.

To mitigate the effects of high temperatures when plastering in the UK, consider the following:

1. Work in the Shade: If possible, work in the shade or during the cooler parts of the day to slow down the drying process.

2. Use Retarders: Plaster retarders are additives that can extend the drying time of plaster, giving you more time to work with it in hot weather. The manufacturers instructions on a popular one called “Extra time” could be used but even that has limits, there are no guarantees over 30 Degrees.

3. Keep Plaster Cool: Store your plaster in a cool, shaded area to prevent it from overheating before use.

4. Hydration: Keep the plastered surface moist by misting it with water occasionally. This can slow down drying and help prevent cracks.

5. Consider Professional Help: If you're not experienced with plastering, it may be wise to hire a professional who can navigate the challenges of hot weather plastering effectively. If you are in the Medway towns & North-Kent area of the UK, give J.E Plastering services a call and we can accurately price the work and get it done for you whatever the weather !

Remember that working with plaster in hot weather can be challenging, and it may require some adjustments to your usual techniques. Patience and careful attention to the drying process are key to achieving a satisfactory plastering job in high temperatures.
