The Flex Seal Liquid Rubber Sealant Coating Spray typically takes 24 to 48 hours to fully cure, but it's dry to the touch within 2 to 3 hours. Factors like temperature, humidity, coating thickness, and ventilation affect how long the seal takes to fully dry. For the quickest and best results, keep the area between 60°F and 90°F, well-ventilated, and with lower humidity, which helps speed up drying. Apply thinner layers of the coating, waiting around 15–30 minutes between each layer to allow it to dry in between.
