Evaluate Sealant Elasticity and Durability

What happens here

The video provides a tangible demonstration of sealant quality by comparing the elasticity of a popular, widely-used silicone sealant with Sashco's 'Big Stretch' sealant. The standard silicone sealant, while having some flexibility, eventually breaks under stress. In contrast, 'Big Stretch' demonstrates significantly superior elasticity, stretching much further before showing any signs of failure. This ability to stretch and recover is vital for stucco applications because buildings constantly expand and contract due to temperature changes and structural shifts. A highly elastic sealant maintains its integrity through these movements, preventing cracks and preserving the seal.

Goal: Assess the elasticity of sealants as a key indicator of their ability to endure environmental stresses, preventing cracks caused by structural movement and temperature changes.
