When painting outside, it is always best to check the tin for the minimum/maximum temperatures. You must also take into account chill factors, especially on metal, as this can reduce surface temperatures considerably. From a health and safety perspective, there isn't a specific minimum or maximum temperature for a worker to paint in. Dress appropriately and stay ventilated/hydrated.
Start with an exterior house wash. It is important that you spend some time washing the dirt and grime off the exterior of your house before you start painting. If the exterior surface of your house is free of paint-repelling soil, the primer and paint will adhere better, making the paint last longer. Most of the time, a simple wash with a hose, a pump sprayer and a scrub brush is sufficient, but if you decide that you would prefer a professional to help you, a power washer in the hands of a professional can provide a superior clean.
