Moistop Sealant can be used as both a sealant and flashing, providing a multi-tasking solution for improved weatherization effectiveness and jobsite efficiency. It is an advanced polymer engineered to be compatible with virtually all building materials. Moistop delivers excellent adhesion and moisture resistance to prevent door and window water leaks, and the expensive callbacks they cause. It also provides flexible, gap-free flashing even around curved intrusions and can fill construction joints up to ½ inch thick.
When used as part of the Henry® 1-2-3 Moisture Control System™, Moistop Sealant is backed by an industry-leading 15-year warranty. Repairs are covered for both materials and labor with a single point of contact.
