Description Firestone Lap Sealant is designed to seal and mechanically protect the exposed cut edge of QuickSeam Products. Lap Sealant is also used as a general purpose sealant in other applications as specified by current Firestone specifications and details. Preparation Surfaces on which Lap Sealant is to be applied must be clean, dry, and free from loose and foreign materials, oil and grease. The surfaces that are to be sealed must be cleaned with QuickPrime Plus. Wait minimum 4 hours between splicing and application of Lap Sealant. Under bad weather conditions, Lap Sealant must be applied before the end of the working day. Restore to room temperature prior to use, if exposed to lower temperatures (< 15ºC) for a prolonged period. Application The sealant is applied with a mastic gun at the specified location using the plastic nozzle applicator supplied by Firestone, being sure to keep the nozzle applicator centred over the lap step-off. Take care to leave a mound of Lap Sealant directly over the splice edge. Coverage Coverage rate of 6 to 7 lm per tube. 4.
