Asbestos Containing Material: Encapsulant

Latex Paint with solids content greater than 15 percent may be used as an encapsulant only as follows:

As a lockdown sealant for coating all non-metallic surfaces, or

For sealing of cementitious ACM.

Encapsulants shall be field tested prior to use by applying each to a small area to determine suitability of the material to be encapsulated.

Testing is to occur only after the isolation barriers are in place.

Testing shall be by the LSEPA method specified in the appendix of "Guidelines for the Use of Encapsulants on Asbestos-Containing Materials" (June, 1981) or ASTM Standard Test Method E736-80. The encapsulated materials shall achieve a cohesive/adhesive strength of 100 lb/ft perpendicular to the surface.

Application of bridging encapsulants over ACM shall provide the manufacturer's specified number of inches or minimum dry film thickness.

A different color for each coat of encapsulant (per manufacturer's specifications) shall be used.
