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 . Use only in conjunction with Duram MULTITHANE or Duarm 195 waterproofing membranes . For details refer Duram MULTITHANE or Duram 195 product data sheets. The MULTISEAL dries by evaporation of the solvent and then cures upon contact with water vapour in the air.
Duram MULTISEAL is formulated to prime most surfaces to be waterproofed using Duram MULTITHANE or Duram 195, included are the following: Concrete, cement and cement render. Timber. Plaster Board and Fibre – Cement sheeting. Brick and Block work. Given its inherent properties, it can also be used as a penetrative sealer. Ensure that the MULTISEAL is dry prior to the application of either MULTITHANE or DURAM 195. Refer fore mentioned note.
MULTISEAL may be applied to the following surfaces: Concrete, cement and cement render. Timber. Plaster Board and Fibre – Cement sheeting. Brick and Block work. Ensure surface is dry prior to application.
