Do you know the difference between silicone structural sealant and silicone weatherproof sealant?
Silicone sealant manufacturer note: weatherproof sealant focuses on joint sealing and exposure resistance, while structural sealant is for load-bearing bonding/structural glazing—select per project specs and the product TDS.

How can one determine whether the phenomenon of blistering is caused by the silicone sealant itself or by the substrate?
A simple way to distinguish bulging vs bubbling and assess whether the issue is more likely related to the sealant or the substrate, based on surface appearance and cross-section inspection.
