Full title and description

ASTM E1795-25 — Standard Specification for Non‑Reinforced Liquid Coating Encapsulation Products for Leaded Paint in Buildings. This specification establishes minimum material performance requirements and laboratory test procedures for non‑reinforced, liquid‑applied encapsulation products (single or multiple‑coat systems) used to encapsulate leaded paint in buildings; it defines three product types for interior, exterior, or either application and describes the performance properties and tests the products must meet.

Abstract

The standard covers minimum material performance and laboratory test procedures for non‑reinforced liquid coating encapsulants intended to reduce human exposure to lead from painted surfaces. Required performance and test areas include impact resistance, adhesion, dry abrasion resistance, water‑vapour transmission, water and chemical resistance, surface burning characteristics, volatile organic compound (VOC) content, weathering and aging, scrub and mildew resistance, paintability/repairability, flexibility, and tensile properties.

Scope

This specification applies to non‑reinforced liquid applied products that rely primarily on adhesion to encapsulate leaded paint surfaces in buildings. It defines the performance properties and laboratory test methods used to evaluate encapsulant materials (impact resistance, adhesion, abrasion, water vapour transmission, water/chemical resistance, surface burning, VOC content, weathering/aging, scrub and mildew resistance, paintability/repairability, flexibility, tensile properties) and notes that the standard does not prescribe the selection of an encapsulant for every specific field condition (see Guide E1796). The standard excludes requirements for corrosion‑inhibiting primers on industrial steel or residential coated metal surfaces and warns that laboratory results may not fully predict field performance.

Key topics and requirements

• Classification of non‑reinforced liquid coating encapsulation products into Type I (interior), Type II (exterior), and Type III (interior or exterior).
• Mandatory performance tests for impact resistance and adhesion.
• Dry abrasion resistance and water‑vapour transmission limits.
• Water and chemical resistance requirements and surface burning characteristics.
• VOC content limits and requirements to test weathering, aging, scrub resistance, and mildew resistance.
• Paintability/repairability, flexibility, and tensile property testing.
• Notes and exclusions: does not select products for specific use conditions; does not include corrosion‑control primer requirements for certain metal substrates.

Typical use and users

Used by encapsulant manufacturers and product development teams to design and certify liquid encapsulation products; by third‑party and in‑house laboratories to perform standardized testing; by lead‑abatement contractors, building owners, architects/specifiers, and regulatory or compliance bodies to evaluate and select encapsulant materials for projects seeking to reduce lead exposure in buildings. The standard is intended to inform specification, testing, and procurement decisions rather than to replace project‑specific evaluation.

Related standards

This specification references or complements other ASTM documents used for selection and testing, notably Guide E1796 (selection considerations for encapsulation products) and Specification E1797 (reinforced liquid coating encapsulation products). Earlier and alternate versions of E1795 (for example E1795‑20A, E1795‑12) provide historical context and revision history.

FAQ

Q: What is this standard?

A: ASTM E1795‑25 is a material performance specification and test procedure standard for non‑reinforced, liquid applied coating products intended to encapsulate leaded paint on building surfaces.

Q: What does it cover?

A: It covers minimum performance requirements and laboratory tests (impact, adhesion, abrasion, water vapour transmission, water/chemical resistance, surface burning, VOCs, weathering/aging, scrub and mildew resistance, paintability/repairability, flexibility, tensile properties) for Type I, II, and III non‑reinforced encapsulants. It also notes exclusions and that field performance may differ from laboratory results.

Q: Who typically uses it?

A: Manufacturers, materials developers, test laboratories, lead‑abatement contractors, building owners, specifiers (architects/engineers), and regulators use the standard to test, qualify, specify, and compare encapsulation products.

Q: Is it current or superseded?

A: E1795‑25 is the active/current edition (published in 2025) and supersedes prior editions (for example E1795‑20A / E1795‑12). The ASTM product page lists E1795‑25 as the active version.

Q: Is it part of a series?

A: Yes — it is part of a family of ASTM documents addressing liquid coating encapsulation for leaded paint: Guide E1796 (selection guidance) and Specification E1797 (for reinforced liquid coating encapsulants) are directly related; prior and amended editions are part of the E1795 revision series.

Q: What are the key keywords?

A: Encapsulation, encapsulant, lead, leaded paint, liquid coating, non‑reinforced, abatement, VOC, adhesion, abrasion, weathering.
