ABC FIBERLOCK BRIDGING ENCAPSULANT-GREEN X 5GAL

Description

GREEN 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 ACM.

1. Encapsulates fireproofing and soil
2. Class A fire rated
3. Exceeds EPA standards for encapsulation
4. Available in off-white, clear and green

How to Use

SURFACE PREPARATION

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 different applications.

APPLICATION TOOLS

Professional models of all brands of airless spray equipment can be used to successfully apply ABC. Use the settings below when applying ABC:

PENETRATING

Pressure: 1300 – 1400 P.S.I. Tip: .017 – .031

BRIDGING

Pressure: 2200 – 3000 P.S.I. Tip: .017 – .023

REMOVAL/LOCKDOWN

Pressure: 2200 – 2300 P.S.I. Tip: .015 – .025

PRODUCT APPLICATION

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.

BRIDGING AGENT

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.

REMOVAL/LOCKDOWN

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 on substrate.

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.

BRIDGING AGENT

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

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.

DRYING TIME

• @ 70°F 50% R.H
• Drying time will vary based on thickness and porosity of the ACM being encapsulated.
• To Touch – 1-2 hours

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 all waste according to current local, state and federal regulations.

PRECAUTIONS

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.
