QUAD MAX seals trim and siding and stays put
Caulk that cracks or pulls away from the joint is worse than no caulk. Water gets behind it, and now you have a hidden problem. QUAD MAX is built to bond tight and stay flexible, so the seal moves with the house instead of splitting open.
It’s made by OSI. You can paint over it in about an hour, which means you caulk and keep working instead of standing around. The clear version is the one to reach for on finished wood or stained trim. Unlike older silicones, it stays clear and resists yellowing from UV.
Colors
- White. The standard for painted trim and siding.
