Full advantage should be taken of weather conditions to carry out painting when the weather is favorable. Paints should never be applied on a wet surface. Not only should painting be avoided in rain, sleet or fog, but also attention must be paid to the presence of condensation on the surface. Generally, painting should be done at over 0 -5°C and below 85% R.H. condition. However, below 5°C some paints such as epoxy slow down dramatically or even stop curing. Other paints such as chlorinated rubber, acrylic and vinyl paints are quite applicable at temperatures even below O°C if the surface is clean and free from ice or frost. Painting should not be carried out when the surface temperature is less than 3°C above the dew point, no matter what the R.H. is at that time.
