Sealcoating & Connecticut’s Weather
Weather conditions play a critical role Sealcoating & Connecticut’s Weather. It determining whether a sealcoating job will be an overwhelming success or a dismal failure. Primarily, it all has to do with the rate at which the water in the sealant will evaporate. There are four weather conditions that can affect this rate of evaporation.
Sealcoating & Connecticut’s Weather – The Four Primary Weather Factors Affecting Evaporation
Evaporation is the process during which the molecules in a liquid break free from the bond holding them to the liquid’s surface. Once freed, water molecules convert to the gaseous state. The four primary factors that influence evaporation are:
3. Air flow
4. Solar energy
The Effect of Heat on Evaporation
Suppose you have three cups of water. You freeze one cup of water and place it beside a cup of water that is at room temperature. Eventually, both cups of water will evaporate; the ice will evaporate slower than the water that is at room temperature. However, if you boil the water in the third cup, it will evaporate much faster than the water in the first two cups. This is because heat makes the water molecules move faster and collide with each other repeatedly, making it easier for the surface bond to be broken.
The basic concept is the same for sealcoating. As temperatures decrease, the water molecules in the sealant do not move as much, so they cannot break free as easily as they can when the temperature is warmer. With the rate of evaporation slowed, the sealant will take longer to dry.
This might lead you to believe that it can never be too hot to apply sealcoating. However, this is incorrect. At very high temperatures, the evaporation occurs too quickly for the sealant to bond to the pavement as it should.
The Effect of Humidity on Evaporation
When water molecules break free and convert to vapor, they need somewhere to go. That somewhere is the air above the liquid. If the air is already saturated with moisture, the escaping molecules have nowhere to go. This slows the drying process, and if the humidity is over 50 percent or so, the impact on drying time can be substantial.
The Effect of Air Flow on Evaporation
As water molecules escape from the sealant, they form a boundary layer over the top of the surface. If they remain there, they prevent additional water molecules from escaping. Wind, even a light, steady breeze, blows away this boundary layer, enhancing evaporation.
The Effect of Solar Energy on Evaporation
Sunlight produces energy that raises the temperature of the air as well as the temperature of the ground. As long as the sun continues to shine, temperatures will be renewed, but if a cloud cover forms, temperatures will slowly begin to decline. Without sunlight, the sealant will take longer to dry completely. Most driveway and commercial asphalt sealcoating jobs are scheduled so that there will be several hours of sunlight remaining after completion.
