FAQs
Q: How do you know when a detail area needs sealant instead of just coating?
A: Detail areas like penetrations, seams, and transitions typically require a sealant when there are gaps, movement points, or irregular shapes that a coating alone cannot fully bridge.
Q: Will this hold up in areas that see frequent movement or expansion?
A: This type of elastomeric sealant is designed to remain flexible after curing, allowing it to accommodate movement in areas where different materials meet or expand and contract.
Q: What makes a pourable grade better for certain applications?
A: Pourable grade is useful when the material needs to flow into tight or uneven areas, helping create a more complete seal in spots where thicker flashing materials may not fully contact the surface.
