Details
Use
Bituthene Mastic is designed to seal terminations,
edges of patches and overlaps in detail
areas. On vertical applications, the mastic
must be applied to both the top and bottom
terminations.
Limitation
Bituthene Mastic is an integral part of the
Bituthene waterproofing system. This mastic
should not be applied where it will be covered
with Bituthene waterproofing membrane,
except as permitted as a temporary cutoff.
It should not be used as a primary waterproofing
material.
Application Procedures:
Safety, Storage and Handling Information
Bituthene products must be handled properly.
Vapors from solvent-based primers and mastic are
harmful and flammable. For these products, the
best available information on safe handling,
storage, personal protection, health and environmental
considerations has been gathered. Material
Safety Data Sheets (MSDS) are available at
graceconstruction.com and users should acquaint
themselves with this information. Carefully read
detailed precaution statements on product labels
and the MSDS before use.
Application
Apply Bituthene Mastic either with a caulking
gun or trowel. If applied with a caulking
gun, level the bead with a trowel to about
0.125 in. (3 mm) thickness and 0.5 in. (13 mm)
to 1 in. (25 mm) width.When applied as a
temporary cutoff, trowel Bituthene Mastic to
0.060 in. (1.5 mm) thickness. Bituthene
waterproofing membrane may be placed over
the thin cutoff the next day.On the bottom edge of vertical applications,
Bituthene Mastic should be troweled upward.
Use it liberally at membrane terminations.
Material usage requirements for Bituthene
Mastic will vary widely from job to job. On
large horizontal plaza areas with few protrusions,
only about one quarter of a tube may be
required per roll of membrane. A vertical
application may require one half tube or more
per roll of membrane. Applications involving
other protrusions may require one or more
tubes per roll.
Clean tools with mineral spirits at the end of
each day. Mineral spirits is a combustible
liquid and should be used only in accordance
with the manufacturer’s safety recommendations.
Do not use solvents to clean hands
or skin.
