Are External Respray Suitable For Winter?

One of the most if not the most important factor to consider when carrying out external spray works is the weather. Temperature and moisture have a substantial effect on paint application meaning external respray works should be avoided in poor weather conditions such as: rain, snow and freezing temperatures. Ideally, external respray works are best suited to the Spring/Summer months where the weather is most likely to be dry and warm.

As a company, we do recommend to keep internal respray works to the winter months and of course external works to the summer months. We do understand that this isn?t always achievable, so below is a quick-tip guide on how to spray outdoors in the winter. With the correct materials, in-depth training and some experience there should be little hindrance to your projects.

Always ensure that moisture is removed from surfaces which are to be resprayed. Prior to paint application. This is one of the most important steps to carry out during the winter months! It is common that moisture and frost sits on surfaces which are to be resprayed of course, this is where issues arise as a coating will not adhere to a damp substrate. If it does appear that the coating has bonded to the surface and the moisture has not been removed properly prior to the recoating this will cause the moisture to become trapped – which leads to premature failure of the paint work.

Curing time will always increase in lower temperatures. Ensure your newly coated surfaces are given enough protection once complete avoiding any damage to paintwork whilst it is still soft.

Weather!?Not only is it important to check the weather for the day of the respray works but also up to two days after your coating has been applied. As mentioned above, curing takes a lot longer in colder months therefore poor weather conditions such as heavy rain may damage the surface once complete.

It is essential to check your coatings temperature range! It is close to impossible for some systems to cure at all in extremely low temperatures. Always do your research and ensure you are using the correct product in line with the correct weather.
