Safety Data SheetHow to UseSURFACE PREPARATION
Use a vacuum with a HEPA filter specifically designed to
capture hazardous dust and waste. Use MSHA/NIOSH approved or equivalent
respiratory protection suitable for concentrations and types of air
contaminants encountered. All Transite substrates must be primed with one of
Fiberlock’s surface conditioners prior to applying TBC. For detailed and
specific information regarding surface preparation, refer to the TBC
specification. TBC must be applied when the atmosphere and surface temperatures
are above 50°F. Do not apply when rain is imminent within three hours after
last application. Inspect all surfaces to be treated to insure they are clean,
dry and free of all foreign matter including: dust, rust, grease, oil, mildew,
loose paint, etc. If Transite is aged and friable, use a liquid applied surface
adhesive such as Grip-Tack to yield a dimensionally stable surface prior to
application of TBC. Mix thoroughly, clear liquid present when container is
opened is an integral part of the product and must be mixed in completely.
APPLICATION TOOLS
Apply TBC with brush, roller or airless spray equipment.
Brush: Synthetic, nylon or polyester bristle
Roller: Synthetic fiber 3/8”-1/2” nap roller
Spray: .019 to .021 tip @ 2500-3000 P.S.I. (Select a machine
capable of a minimum output capacity of 0.50 gallons per minute.)
PRODUCT APPLICATION
Apply liberally and uniformly. Multiple coats may be
necessary to achieve desired dry thickness. Allow TBC to dry before applying
additional coats. TBC may be top coated with paint to provide desired color or
aesthetic finish. The necessary dry film
thickness of a bridging encapsulant for asbestos containing materials (ACM) will
vary from project to project as ACM can have a wide range of characteristics,
including density, porosity, and surface profile. In the EPA’s Guidance for
Controlling Asbestos-Containing Materials in Buildings (EPA 560 / 5-84024, June
1985), the primary instruction regarding dry film thickness states that when
encapsulating ACM, the coating is to be applied “considerably thicker than
recommended for painting. Coverage should be no more than 100 sq. ft. per
gallon and should create a continuous, unbroken coating” (Section 5.1.3, page
5-8).
COVERAGE
Transite Surface: 50-100 ft2/gal. [Coverage depends on
porosity of material and desired film thickness.]
DRYING TIME
@ 70°F 50% R.H
To Touch: 1 to 2 hours
To Recoat: 8 to 16 hours
To Full Cure: 12 to 24 Days
CLEANUP
Tools and drippings should be cleaned with warm soapy water
before coating dries. Follow equipment manufacturer’s directions to clean spray
equipment. Dispose of waste according to all existing local, state and federal
regulations.
PRECAUTIONS
Store in a dry place at temperatures between 40°F (4.5°C)
and 90°F (32°C). Close container after each use; keep container tightly sealed
when not in use. When applying with a sprayer, wear a NIOSH approved respirator
with any R, P, N or HE filter. Use adequate ventilation to avoid over exposure.
Surfaces coated with TBC must be inspected routinely. Damaged surfaces should
be repaired and TBC should be reapplied immediately to prevent exposure to the
asbestos hazard. Do not dilute, thin or mix with any other product. Store in a
dry place at temperatures between 50°F and 80°F. TBC is sensitive to heat and
time. Asbestos abatement activities must be performed in accordance with all
applicable regulations including EPA, OSHA, federal, state and local. For more information always contact the
appropriate agencies prior to beginning any abatement project.
