Two part sealants like Polysulphide sealant, Polyurethane sealant, and Silicone sealant take approximately 2-3 hours to fully cure. During this time, they chemically bond to the glass, creating a durable and airtight seal. At Glasscraft, we ensure our Polysulphide sealant and Silicone sealant are correctly cured for maximum performance.
