<\/span> PAINTING TIPS<\/span>

In coastal South India, humid days are the norm, not the exception. Paint can still go on well, but humidity changes how it dries. Here is what happens to paint in humid weather, when it is too humid, and how to get a good result.<\/p>

Short answer:<\/strong> Yes, you can paint when humidity is high, but paint dries more slowly and needs more care. In humid air, water in the paint evaporates slowly, so coats stay soft longer, take longer to recoat and are more easily marked by dew or rain. Very high humidity, especially when it is near the point where dew forms, can cause poor adhesion, streaks and a cloudy finish. Paint in the warmest, driest part of the day, ventilate well, apply thin coats, allow extra drying time, and never paint a surface that is damp or covered in condensation.<\/p><\/div>\n

How does humidity affect paint?<\/h2>\n

Water-based paint dries as its water evaporates. Relative humidity is how much moisture the air already holds. The more moisture in the air, the slower the water in the paint can escape.<\/p>\n

How humid is too humid to paint?<\/h2>\n

There is no single number for every product, but many paint makers advise against painting in very high humidity, often above about 85% relative humidity, and when the surface is close to the dew point, where moisture can condense on it. For steel, a common protective-coatings rule is that the surface should be at least 3°C above the dew point. Always follow the product label and your dealer’s advice.<\/p>\n
