Application
 For ease of application, unroll BG700 and allow it to relax
for at least 15 minutes.
 Install the membrane either horizontally or vertically,
depending upon the project considerations.
 Arrange the membrane in a straight manner and remove
the release film in a gradual fashion. Then apply uniform
pressure using a 28-lb weighted roller to ensure 100%
bond to the underlying substrate.
 Apply the membrane starting at the lowest point,
working the way to the highest point.
Warranty
LeakBarrier BG700 is warranted to be free from manufacturer’s defects.
