What effect does high relative humidity or freezing temperatures have on Liquid Roof/Liquid Rubber?
Liquid Roof/Liquid Rubber can be applied under high humidity conditions as long as the roof is dry and its temperature is above the dew point. The solvent evaporation is governed by temperature only and is not influenced by relative humidity. If the temperature drops below freezing after it has been applied no damage will result. The rubber will slowly stiffen as the solvent evaporates and begin to cure when the temperature exceeds 55 degree F. The ultimate physical properties of the EPDM rubber membrane will always be the same regardless of the length of time needed to reach the full cure stage. Q:: How much time is available to work with it after the catalyst has been mixed in? A: On a hot day (above 80 degrees F. the working time will be approximately four hours until the rubber becomes noticeably thicker and more difficult to apply. Working time is considerably longer at lower temperatures. The rubber will thicken faster in direct sunlight and when liquid level is low in the contai
