Night-Lock™ Roofing Sealant

  • Environmentally Friendly
  • High Rising & Flexible
  • Fast Application

Night-Lock is a flexible, solvent-free, quick-setting, night tie-in foam sealant—the unique formulation results in a foam with a weatherproof "skin" that is secured almost immediately. Application is quick and easy since no expensive specialty pumps or spray rigs are required, resulting in significant labor savings for the contractor. Night-Lock is intended for temporary tie-in locations between new roof covers and existing roof systems. Night-Lock replaces asphalt mastics and bitumens or less reliable porous surface foams by providing a clean, secure seal for overnight waterproofing protection.

High Rising & Flexible

As a fast-acting, high-rise foam, Night-Lock accommodates surface irregularities to form a watertight seal to keep your roof system dry. Night-Lock's elastomeric composition allows it to absorb stress in the roof system and remain flexible in application and protection.
