General Installation Information:

See applicable instructions for detailed information on new roofingand reroofing for various deck types. Field application and flashingtechniques are critical in securing a watertight roof. Applicationinstructions must be followed exactly. There is no substitute for goodworkmanship by experienced, trained applicators.

Follow the specific, detailed instructions for the specific application.Do not substitute materials. If questions arise, contact your Tremcorepresentative.

Notes:1) Do not use BURmastic as the adhesive for a water dam.2) Do not use BURmastic Base Sheet Adhesive on systems applied

over Tectum or gypsum decks.3) Wood and Tectum decks require a rosin sheet below the base sheet.

BURmastic 100B - 3 Ply Roof Membrane Installation:

After adhering base sheet, install layers of BURmastic Glass Ply feltsin shingle fashion. Place in such a manner as to ensure that water willflow over or parallel to, but never against, exposed edges.1) Install base sheet in continuous layer of BURmastic Base Sheet

Adhesive or Premium III or Premium IV Asphalt.2) Starting at the low point of the roof, spray or brush apply a uniform

coating of BURmastic Adhesive over the base sheet at the rate of1.2 L/m2 (3 gal/100ft2)*.
