The normal life span of silicone units is approximately 20 years, however continuous high temparature applications may affect the service life. All surfaces to be bonded must be clean and dry and free from contaminants such as old sealant or oil.The maximum open time for some sealants is ten to fifteen minutes in humid conditions, with thirty minutes the maximum in dry conditions. 

The sealant should be applied in a continuous steady flow to achieve a fully filled void free joint. The roofing silicone should be applied throughout the line of the intended fasteners for bonding to avoid entrapment of air and to ensure that the fasteners are thoroughly sealed within the lap.The sealed lap should not exceed 25mm. 

Wider laps should be sealed at each end of the lap if necessary rather than filling the total lapped area. When the sealing is complete, any excess roofing silicone should be removed. We recommend a plastic spatula as opposed to a cloth, which has a tendency to contaminate the area with residue and look untidy if dust adheres to it.
