Product Details

Superior Waterproofing Primer for Maximum Membrane Performance

Duram Multiseal is a professional-grade liquid polyurethane primer engineered to improve the adhesion, durability, and application performance of Duram waterproofing membranes. Using advanced cross-linking technology, Multiseal creates an exceptionally strong chemical bond with Duram Multithane, Multithane HV, and Duram 195 membranes, helping deliver reliable long-term waterproofing results.

The penetrating formulation seals porous substrates, binds loose surface particles, reduces dusting, and promotes smoother membrane application while improving overall coverage rates. In addition, Multiseal provides a penetrative secondary waterproofing barrier, making it an ideal primer for a wide range of residential, commercial, and below-ground waterproofing projects.

Its single-pack, moisture-curing design allows for easy application by brush, roller, squeegee, or spray, with a generous top-coating window for efficient project scheduling.
