Repairing Large Cracks: Using Backer Rod & Big Stretch Caulking

Watch on YouTube

What happens here

Choose a high-quality sealant. The video initially considers Sashco Slab, a textured concrete sealant, but discards it because the existing soffit sealant is smooth. Instead, Sashco Big Stretch sealant is selected. Big Stretch is a high-performance, water-based elastomeric sealant known for its strong adhesion, superior elasticity, and ability to stretch and flex with movement without cracking. This is crucial for areas subject to expansion and contraction.

Goal: Choose an appropriate sealant that matches existing textures and offers flexibility.
