Duram Multiseal – 4L or 15L

Duram Multiseal is a moisture curing, single pack, liquid polyurethane penetrating waterproofing primer. It is formulated to compliment Duram Multithane and Duram 195 membranes as it is manufactured from identical resins contained in Multithane or Duram 195. As the resins employ cross-link technology the chemical bond between the Multiseal, Multithane or Duram 195 is exceptionally strong.

Multiseal as a primer: Improves the adhesion and performance of the membrane, ‘locks -down’ dust and loose materials, improves the spreading and application of the subsequent membranes, provides a penetrative secondary waterproof barrier and improves the coverage of the Multithane and Duram 195 membranes.

Multiseal is a penetrative sealer and provides a penetrative waterproof barrier when applied in 2 coats or more.

DO NOT use as a primary waterproofing membrane.

The MULTISEAL dries by evaporation of the solvent and then cures upon contact with water vapour in the air.
