OCCUPATIONAL TRAINING AND SUPPLY
ABC Asbestos Binding Compound is an asbestos sealant that
encapsulates friable Asbestos Containing Material (ACM), such as fireproofing
and insulation material, and meets the requirements for effective encapsulation
and removal of ACM. ABC provides maximum flexibility for specific asbestos
abatement needs, including lockdown, removal, penetrating encapsulation and
bridging encapsulation, and is an effective tool for controlling the documented
health hazard of exposure to asbestos fibers found in soil.
ABC was tested for the EPA by Battelle Laboratories and
found to meet the requirements for the effective encapsulation and removal of
- High solids asbestos encapsulant/sealant, designed to
encapsulate friable Asbestos Containing Material (ACM)
- Applications: Ideal for use on fireproofing and insulation
material *Effective for controlling asbestos fibers in soil
Prior to application it is important to determine if the
existing asbestos matrix is well adhered to the substrate. Correct any surface
defects and clean all surfaces thoroughly. Be careful not to agitate asbestos
fibers during preparation; this could increase asbestos exposure. Stir ABC
thoroughly to achieve a uniform consistency. ABC may be diluted with water for
Professional models of all brands of airless spray equipment
can be used to successfully apply ABC. Use the settings below when applying
Pressure: 1300 – 1400 P.S.I. Tip: .017 – .031
Pressure: 2200 – 3000 P.S.I. Tip: .017 – .023
Pressure: 2200 – 2300 P.S.I. Tip: .015 – .025
ENCAPSULATION INSTRUCTIONS PENETRANT
For most fibrous asbestos applications such as “cotton
candy” style fireproofing or compressed acoustic material less than 2 inches
thick, add 1 part water to 1 part ABC. Using the proper spray equipment
settings listed, apply ABC to the ACM until saturated. Multiple passes may be
required, allowing time between passes for dissipation of the solution into the
matrix. Full saturation is achieved when the ACM will not absorb any more of
the encapsulant into the matrix. Coverage, depending on thickness and porosity
of the material, can vary between 50 – 75 sq. ft./gal.
A qualified asbestos professional should determine the
necessary dry film thick ness for individual abatement projects. 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). For bridging applications, apply ABC at full strength with an
airless sprayer in accordance with the settings listed below. Typical bridging
applications are applied at a coverage rate of 75-100 sq. ft./gallon, which
yields a dry film thickness between 6-10 mils on hard, cementitious ACM. For
more information, contact Fiberlock or visit our website for the complete
Specification for ABC.
Removal is recommended for loosely adhered ACM. Mix 4 parts
water to 1 part ABC and apply to ACM. ABC will facilitate removal by
penetrating into the ACM keeping it moist and sticky. After the ACM has been
removed, apply 1 part ABC diluted with 1 part water to seal residual fibers left
SOIL ENCAPSULATION INSTRUCTIONS PENETRANT
For encapsulation of soil contaminated with asbestos, mix
one part ABC with one part water. Apply as a penetrating encapsulant to
increase the dimensional stability of the soil, while reducing its
porosity. For heavy clay or hard packed
soils, the dilution rate may need to be increased to 2 parts water to one part
ABC to improve penetration. Porous
soils, such as those with high sand or gravel content, may require more product
per square foot, or multiple applications of penetrating encapsulant solution.
Apply ABC full strength as a bridging encapsulant. Dry film thickness and application rate
should be determined by a qualified asbestos professional as appropriate to the
project site and goals.
Coverage depends on thickness and porosity of the material.
Penetrant: 50-75 ft2 per gallon
Penetrant (Soil): 30-35 ft2 per gallon.
Bridging Agent: 75-100 ft2 per gallon.
Bridging Agent (Soil): 75-100 ft2 per gallon.
@ 70°F 50% R.H
Drying time will vary based on thickness and porosity of the
ACM being encapsulated.
To Touch – 1-2 hours
Tools and drippings should be cleaned with warm soapy water
before coating dries. Follow equipment manufacturer’s directions to clean spray
equipment. Dispose of all waste according to current local, state and federal
Store in a dry place at temperatures between 40°F (4.5°C)
and 90°F (32°C). Approved respirators must be used to prevent inhalation of
asbestos fibers that may be present in the air. Protective clothing should be
worn. When applying with a sprayer, wear a NIOSH approved respirator with any
R, P, N or HE filter.
