The weather plays a significant role in our lives and especially when it comes to painting. When to or not to paint is an essential choice if you require great finishes. There are golden rules that require you not to paint when the Relative Humidity is higher than 85% or if the Dew Point is closer than 3 degrees to the surrounding air temperature.
Humidity is induced by water in the ambiance, and it poses severe problems to painters who would like to work on humid days. Normally a painter is supposed to wait for the humidity to pass, however it is not always the case. Various steps can be adhered to counteract the dilemma of moisture on paint and allow painters to work on humid days.
5 Steps That Can Help You Paint In Humid Weather
1. Clean and dry up the part to be painted as much as probable. Water can occupy wood, stone and metal and encourage the growth of mold. Adding paint in a humid weather can worsen the matter.
2 .Purchase the paints and primers that work appropriately for humid days. Keep away from solvent-based products and use of latex-based primers and mold-defiant paints.
3. Paint early in the morning hours. Paints that are latex-based employ water as a solvent. During drying, water vanishes from the film, leaving behind a tough, hard-wearing coat. The vaporization of water relies on surrounding humidity and temperature. When the temperature rises, humidity falls, encouraging the evaporation of water from the coating. Stop painting in case the temperatures start to fall.
4. Trail the sun’s pattern. Paint first on areas that had been unsheltered from the sun but are no longer directly exposed to sunlight.
5. Allow the primers to dry thoroughly, as indicated on the manufacturer’s instructions, before adding a coat of paint.
1. For the paint to dry out, the water in it must disappear either quickly or simultaneously as the solvents contained in it. The paint might not stick to the painted area appropriately if it does not vanish rapidly enough. The same predicaments crop up with oil-based paints. If the paint tries to cure earlier than the water, then the painted surface will have to be repainted.
2. Ensure that you are very careful while painting metal surfaces on humid days. Humidity hinders the paint from drying and sticking properly. Paint does not stick willingly to metal, and wet weather only worsens the situation.
3. Moisture does not only have an effect on the painting process — it also causes swelling of wood, which results in cracks. Always watch out for this situation and dry, renovate and repaint as needed to avoid rotting of wood.
So When Should You Paint?
The temperature of your home affects the outcome of the paint job. The temperature of the walls must be higher than 10C or 50F during the painting process. Avoid painting in exceedingly cold or hot conditions.
If it looks like it is going to rain, do not dare to paint, there is nothing is more disheartening than seeing your work spoiled!
Play within the temperature instructions for painting as declared on product information sheets while bearing in mind that the finest and easiest temperatures to paint are those in the middle of the suggested ranges i.e. moderate conditions in preference of extremes.
