About This Product


The primary cause of water intrusion is the lack of properly integrated flashing around windows, doors, and other fenestrations. The cost of these repairs and potential exposure to litigation can be staggering, particularly when water leakage leads to problems with mold and mildew. Moistop Sealant and Liquid Flashing can be used as both a sealant and flashing, providing a multi-tasking solution for improved weatherization effectiveness and jobsite efficiency.

Moistop Sealant and Liquid Flashing is an advanced polymer designed to be compatible with virtually all building materials. Moistop delivers excellent adhesion, compatibility, durability and moisture resistance to prevent door and window water leaks, and the expensive callbacks they cause. It is also suitable for use in construction joints up to one-half inch in width. Moistop exceeds ASTM C920 and AAMA 808.3-92 (Exterior Perimeter Sealing Compounds) standards.

Durable Liquid Applied Flashing used as a liquid flashing system, Moistop Sealant and Liquid Flashing provides gap-free protection to rough and irregular surfaces. It is particularly useful when applying flashing to curved intrusions like vents and plumbing, and is highly effective with masonry window and door installations. Where specified as a liquid applied flashing, the product exceeds AAMA 714 standards. And even though Moistop is tough enough to repair torn vapor barriers, it is smooth enough to take paint in visible application areas.

  • Exceeds AAMA 808.3 and ASTM C920 standards
  • Optimal adhesion on most surfaces
  • Conforms to any shape and fills joints up to ½" wide
  • Paintable and durable
  • Excellent balance between water resistance and permeability
