ASTM International Standard Specification for Reinforced Liquid Coating Encapsulation Products for Leaded Paint in Buildings (Withdrawn 2026) ASTM E1797-12(2017)e1

This specification covers minimum material performance requirements and laboratory test procedures for reinforced liquid coating encapsulation products (single- or multiple-coat systems) for leaded paint in buildings. It applies to any liquid-applied product incorporating reinforcement materials as part of the system. Reinforcement materials are continuous fabric or mesh and are applied in the field. These materials are typically applied between a base and top coat. These products are used to encapsulate a leaded paint surface with the intent of reducing human exposure to lead in paint. These are classified into three types which are Type I which are encapsulation products are intended for interior use, Type II which are encapsulation products intended for exterior use, and Type III which defines encapsulation products intended for either interior or exterior use. Different tests shall be conducted in order to determine the following performance properties for reinforced liquid coating encapsulation products such as impact resistance, adhesion, dry abrasion resistance, water vapor transmission, water resistance, chemical resistance, surface burning characteristics, volatile organic compound content, weathering, aging, scrub resistance, mildew resistance, paint ability and repairability. Testing conducted shall be performed on the entire encapsulation product system, whether single or multiple coat, as applied in the field, except for scrub resistance, volatile organic compound (VOC) content, and permeability, which are performed on the top coat only.
