At Ignas we are very happy that the weather is slowly but steadily improving! Why is it so important to us? Apart from the fact that we love the sun, these are also perfect conditions for painting and decorating the outside of buildings!
The impact of weather on painting and decorating
Many of our customers ask us how the weather affects exterior wall painting. The most common questions are – what is the best weather for painting? Under what conditions does the coating dry best? When are paints best applied? That’s perfectly understandable – customers who choose to paint and decorate their homes themselves, usually do so in their spare time, and this doesn’t always conveniently line up with when the weather is just right for painting – especially considering that the weather in London can be fickle.
The conditions under which we paint affect not only the comfort of painting – although this is of course also an important factor for our customers – but also the effect. The properties of the paint coating formed during painting vary depending on the temperature during painting and the weather conditions when the paint dries off. We believe that the ideal temperature is 15-20 ° C. However, it is not only the temperature that impacts the effect – air humidity and wind intensity are just as important. In our experience as painters and decorators in London, the ideal conditions are around 70-80% for humidity and a very light wind. Of course, this does not mean that you cannot paint under different conditions – it just requires a slightly different approach and more experience.
Apart from the humidity, wind intensity and temperature mentioned, the sun and the associated UV radiation also play an important role. Strong, direct sunlight will affect the properties of the paint binder, causing the coating to erode. Of course, some types of paints are more resistant to this weather factor – for example, water-based paints offer more resistant binders, as opposed to solvent-based paints, which decompose harder under the influence of UV radiation.
