Although it sounds like a disadvantage it really is one of the key benefits and here is why. How long will it take for the liquid roof liquid rubber to cure. Heavier films may take longer. Do not apply liquid roof in a heavy film as this will aggravate the swelling reaction in the sheet.

At 70 degrees fahrenheit and above it will take approximately 14 hours for the rubber to feel solid to the touch. The lowest temperature at which any cure takes place is 55 degrees. At first glance this may seem like a disadvantage until you realize that even when wet the material provides a waterproof barrier. If rafters are too skimpy the roof will sag especially along the ridge.

Another unique advantage is the slow cure time or the time it takes for the liquid material to fully adhere and harden on the roof deck. Generally 24 hours until it develops a skin and approx 72 hours until you can walk on it. Other coatings dry quickly leaving air trapped between the substrate and the coating this provides for an unstable roof coating and eventually leads to cracking and separation.
